CSQX001I

csect-name Channel initiator starting

Severity

0

Explanation

The channel initiator address space is starting, in response to a START CHINIT command.

System action

Channel initiator startup processing begins. Message CSQX022I is sent when the startup process has completed.

CSQX002I

csect-name Queue sharing group is qsg-name

Severity

0

Explanation

This is issued during channel initiator startup processing or in response to the DISPLAY CHINIT command if the queue manager that the channel initiator uses is in a queue sharing group.

System action

Processing continues.

CSQX003I

csect-name Obsolete parameter module ignored

Severity

0

Explanation

The START CHINIT command specified a parameter module name using the PARM keyword. The use of a channel initiator parameter module is obsolete, so the name is ignored.

System action

Processing continues.

System programmer response

Channel initiator parameters are specified by queue manager attributes. Use the ALTER QMGR command to set the values you want.

CSQX004I

Channel initiator is using mm MB of local storage, nn MB are free

Explanation

Displays the amount of virtual storage currently used and available in the extended private region. Both values are displayed in megabytes (1048576 bytes), and are approximations.

This message is logged at channel initiator start and then either every hour if the usage does not change or when the memory usage changes (up or down) by more than 2%.

System action

Processing continues.

System programmer response

No action is required at this time. However, a frequent occurrence of this message might be an indication that the system is operating beyond the optimum region for the current configuration.

The ddname data set could not be opened, as reported in the preceding messages.

System action

Processing continues, but functions that require the data set will be inhibited. For example, if the exit library data set CSQXLIB cannot be opened, user channel and channel auto-definition exits will not be available, and channels that use them will not start. If the error information data set CSQSNAP cannot be opened, the error information will be lost.

System programmer response

Investigate the problem reported in the preceding messages.

CSQX013I

csect-name Address conflict for listener, port port address ip-address, TRPTYPE=TCP INDISP=disposition

Severity

4

Explanation

A STOP LISTENER or START LISTENER command was issued specifying TRPTYPE(trptype) and INDISP(disposition), but that listener was already active for a port and IP address combination that conflicted with the requested port and IP address. If ip-address is '*', all IP addresses were requested.

The port and IP address combination specified must match a combination for which the listener is active. It cannot be a superset or a subset of that combination.

System action

None.

System programmer response

Reissue the command correctly if necessary.

CSQX014E

csect-name Listener exceeded channel limit, TRPTYPE=trptype INDISP=disposition

Severity

8

Explanation

The number of current channels using the indicated communications system trptype is the maximum allowed. The listener cannot accept an incoming request to start another channel; if the maximum is 0, the listener itself cannot start. (The name of the channel requested cannot be determined because the listener could not accept the request.) Current channels include stopped and retrying channels as well as active channels.

disposition shows which type of incoming requests the listener was handling:

QMGR

those directed to the target queue manager

GROUP

those directed to the queue sharing group.

The maximum allowed is specified in the TCPCHL or LU62CHL queue manager attribute, but may be reduced if a dispatcher fails, or if TCP/IP resources are restricted (as reported by message CSQX118I).

System action

The channel or listener does not start.

System programmer response

If the maximum allowed is zero, communications using the indicated system trptype are not allowed, and no such channels can be started. The listener also cannot be started. If the maximum allowed is non-zero, wait for some of the operating channels to terminate before restarting the remote channel, or use the ALTER QMGR command to increase TCPCHL or LU62CHL.

CSQX015I

csect-name started dispatchers started, failed failed

Severity

0

Explanation

The channel initiator startup procedure has started the requested number of dispatchers; started dispatchers started successfully and failed dispatchers did not start.

System action

The channel initiator startup processing continues. The number of current TCP/IP and LU 6.2 channels allowed will be reduced proportionately if some dispatchers did not start.

System programmer response

If the message indicates that some dispatchers failed, investigate the problem reported in the preceding messages.

Severity

0

Explanation

The Distributed Pub/Sub command Offloader task has stopped. This can be for one of three reasons:

• The channel initiator is stopping.
• The channel initiator is starting and the queues used by the distributed pub/sub offloader have not been defined because distributed pub/sub command processing is not required.
• An error has occurred.

System action

Processing continues, but distributed pub/sub is not available.

System programmer response

If an error has occurred, investigate the problem reported in the preceding messages.

CSQX066E

csect-name Refresh proxy subscriptions failed

Severity

8

Explanation

A REFRESH QMGR TYPE(PROXYSUB) was issued, but could not complete. This could be because the Channel Initiator is shutting down, or as a result of an error.

System action

Processing continues, but remote subscriptions are not resynchronized.

System programmer response

If an error has occurred, investigate the problem reported in the preceding messages.

CSQX067E

csect-name Error removing non durable remote subscriptions

Severity

8

Explanation

The Pub/Sub Offloader task is ending but was unable to remove one or more remote proxy subscriptions. If no previous error has occurred, this is likely to have been triggered by Queue Manager shut down.

System action

Processing continues, but remote subscriptions might continue to exist which are no longer valid. This could cause a build-up of publications for this Queue Manager on remote transmission queues.

System programmer response

If the Queue Manager is to be restarted immediately, these subscriptions will be cleaned up when initial resynchronization with the cluster occurs. If this is not the case, proxy subscriptions might need to be manually removed using DELETE SUB on other Queue Managers in the cluster. Investigate the problem reported in the preceding messages to see why resynchronization failed.

CSQX068I

csect-name Channel initiator has scavenged mm MB of transmission buffers

Explanation

Displays the amount of virtual storage that has been freed by the channel initiator transmission buffer scavenger task. This virtual storage value is displayed in megabytes (1048576 bytes), and is an approximation.

This message is logged when the amount of virtual storage used by the channel initiator is more than 75%. If storage has been freed the CSQX004I message is issued.

System action

Processing continues.

System programmer response

No action is required at this time. However, a frequent occurrence of this message might indicate the system is operating beyond the optimum region for the current configuration.

CSQX069E

Severity

4

Explanation

Use of TCP/IP with the UNIX System Services (USS) sockets interface was requested, but an error occurred. return-code and reason are the return and reason codes (both in hexadecimal) from the USS service serv that gave the error.

The most likely causes are:

• The user ID that the channel initiator uses is not set up correctly for use with USS. For example, it may not have a valid OMVS segment defined or its security profile may be incomplete.
• The TCPNAME queue manager attribute does not specify a valid TCP/IP stack name. These stack names are defined in the SUBFILESYSTYPE NAME parameter in member BPXPRMxx for SYS1.PARMLIB.
• The MAXFILEPROC or MAXPROCUSER parameter in member BPXPRMxx for SYS1.PARMLIB is too small.

System action

Processing continues, but communications using TCP/IP with the USS sockets interface will not be available.

csect-name TCP/IP channel limit reduced to nn

Severity

0

Explanation

This is issued during channel initiator startup processing and in response to the DISPLAY CHINIT command if the maximum number of current TCP/IP channels allowed is less than is specified in the TCPCHL queue manager attribute. This error can occur because:

• TCP/IP resources are restricted. The UNIX Systems Services MAXFILEPROC parameter (specified in the BPXPRMxx member of SYS1.PARMLIB) controls how many sockets each task is allowed: that is, how many channels each dispatcher is allowed
• Some dispatchers have failed and not been restarted; the number of current TCP/IP channels allowed is reduced proportionately

System programmer response

If TCP/IP resources are restricted, consider increasing either the UNIX Systems Services MAXFILEPROC parameter or the number of dispatchers if you need more current TCP/IP channels.

CSQX119I

csect-name LU 6.2 channel limit reduced to nn

Severity

0

Explanation

This is issued during channel initiator startup processing and in response to the DISPLAY CHINIT command if the maximum number of current LU 6.2 channels allowed is less than is specified in the LU62CHL queue manager attribute.

CSQX191I

csect-name Channel channel-name beginning message reallocation

Severity

0

Explanation

The channel channel-name is entering message reallocation because it cannot currently deliver messages to the destination queue manager.

System action

Messages that are not bound to a particular queue manager will be workload balanced. This may take some time if there are a large number of messages assigned to this channel. Check how many using the DISPLAY CHSTATUS(channel-name) XQMSGSA command.

System programmer response

If reallocation is not required, for example because the destination queue manager is now available, reallocation can be interrupted using STOP CHANNEL MODE(FORCE).

CSQX192E

csect-name Channel channel-name unable to stop, message reallocation in progress

Severity

8

Explanation

A request to stop channel channel-name was made, but the channel cannot stop immediately because message reallocation is taking place.

System action

The channel continues to reallocate messages. This process can take some time to complete if there are a large number of messages assigned to the channel on its transmission queue. An increase in CPU utilization might be observed during this time. Upon completion of the reallocation process the channel ends.

System programmer response

The number of messages to be reallocated can be determined using the DISPLAY CHSTATUS(channel-name) XQMSGSA command.

Turn on the MONCHL attribute of the channel and check how many users are using the DISPLAY CHSTATUS(channel-name) XQMSGSA command. The value of MONCHL should be LOW,MEDIUM or HIGH. See MONCHL for further information.

If reallocation is not required, for example because the destination queue manager is not available, reallocation can be interrupted using the STOP CHANNEL MODE(FORCE) command.

TCP

TCP/IP

LU62

APPC/MVS

The return code from it was: (in hexadecimal) return-code, (in text) return-text. For some errors, there may also be an associated reason code reason (in hexadecimal) giving more information.

System action

The channel is not started.

System programmer response

The error may be due to an incorrect entry in the channel definition or some problems in the APPC setup. Correct the error and try again

It could also be that the listening program at the remote end is not running. If so, perform the necessary operations to start the listener for trptype, and try again.

See Communications protocol return codes for information about the cause of the return code from the communications system. If using TCP/IP, see the z/OS UNIX System Services Messages and Codes manual for information about the reason code.

The return code from it was: (in hexadecimal) return-code, (in text) return-text. For some errors, there might also be an associated reason code reason (in hexadecimal) giving more information.

System action

The attempt to start the channel is retried.

System programmer response

Try again later.

A likely cause is that the listener at the remote end was not running or has been started using the wrong port or LU name. If this is the case, perform the necessary operations to start the appropriate listener, and try again.

See Communications protocol return codes for information about the cause of the return code from the communications system.

If using TCP/IP, see the z/OS UNIX System Services Messages and Codes manual for information about the reason code.

If you receive reason code 468:

• You are not using the correct IP address.
• The listener for the port might not be active.
• A firewall does not allow the connection.

  When there are multiple links defined on a z/OS image, the image can have multiple host names depending on the link. You need to ensure that the correct host name is used as the sender end. Use the NETSTAT HOSTs command to display the host names on the image.

The return code from it was: (in hexadecimal) return-code, (in text) return-text. For some errors, there might also be an associated reason code reason (in hexadecimal) giving more information.

System action

The channel is not started.

System programmer response

See Communications protocol return codes for information about the cause of the return code from the communications system.

Probable causes are:

• If the communications protocol is TCP/IP:
  • The connection name specified is incorrect, or that it cannot be resolved to a network address, or the name may not be in the name server. Correct the error and try again.
  • If the return code is zero, there is a name server problem. The OMVS command OPING usually fails in the same way. Resolve this failure and restart the channel. Check the /etc/resolv.conf file and check that the correct name server address is specified in the NSINTERADDR statement.
• If the communications protocol is LU 6.2:
  • One of the transmission parameters (MODENAME or TPNAME or PARTNER_LU) in the side information is incorrect, or that there is no side information for the symbolic destination name specified as the connection name. Correct the error and try again.
  • An LU 6.2 session has not been established, perhaps because the LU has not been enabled. Issue the z/OS command VARY ACTIVE if this is the case.

See the z/OS UNIX System Services Messages and Codes manual for information about the reason code.

csect-name Listener stopped - error accepting new connection, TRPTYPE=TCP INDISP=disposition

Severity

8

Explanation

An error occurred in the listener accept processing. The listener was notified by TCP/IP, but no attach request was received.

disposition shows which type of incoming requests the listener was handling:

QMGR

those directed to the target queue manager

GROUP

those directed to the queue sharing group.

System action

The listener stops. The channel initiator will attempt to restart it, at the intervals specified by the LSTRTMR queue manager attribute.

System programmer response

The failure might be transitory, try again later. If the problem persists, it might be necessary to stop some other jobs that use TCP/IP, or to restart TCP/IP.

CSQX259E

csect-name Connection timed out, channel channel-name connection conn-id (queue manager qmgr-name) TRPTYPE=trptype

Severity

8

Explanation

The connection conn-id timed out. The associated channel is channel-name and the associated remote queue manager is qmgr-name; in some cases the names cannot be determined and so are shown as '????'. trptype shows the communications system used:

TCP

TCP/IP

LU62

APPC/MVS

Probable causes are:

• A communications failure.
• For a message channel, if the Receive Timeout function is being used (as set by the RCVTIME, RCVTTYPE, and RCVTMIN queue manager attributes) and no response was received from the partner within this time.
• For an MQI channel, if the Client Idle function is being used (as set by the DISCINT server-connection channel attribute) and the client application did not issue an MQI call within this time.

System action

The channel stops.

System programmer response

For a message channel, check the remote end to see why the time out occurred. Note that, if retry values are set, the remote end will restart automatically. If necessary, set the receive wait time for the queue manager to be higher.

For an MQI channel, check that the client application behavior is correct. If so, set the disconnect interval for the channel to be higher.

CSQX261E

csect-name No suitable IP stack available, channel channel-name, connection conn-id

Severity

8

Explanation

An attempt to allocate a conversation on connection conn-id for channel channel-name using TCP/IP communications was not successful because the IP stack used did not support the IP address family required for the connection.

System action

The channel is not started.

System programmer response

If the channel's CONNAME attribute resolves to an IPv6 address, then ensure the stack being used by the combination of the TCPNAME queue manager attribute and the channel's LOCLADDR attribute supports IPv6. If the channel's CONNAME attribute resolves to an IPv4 address, then ensure the stack being used by the combination of the TCPNAME queue manager attribute and the channel's LOCLADDR attribute supports IPv4.

CSQX262E

csect-name Communications canceled, channel channel-name TRPTYPE=trptype

Severity

8

Explanation

An unexpected communications error occurred for a listener or a channel. This error occurs if the channel was stopped with mode FORCE and the communications session was canceled.

The channel is channel-name; in some cases its name cannot be determined and so is shown as '????'. trptype shows the communications system used:

TCP

TCP/IP

LU62

APPC/MVS

System action

The channel is stopped.

System programmer response

Restart the channel if appropriate.

CSQX293I

csect-name Channel channel-name has initiated a switch of transmission queue from old-xmitq to new-xmitq

Severity

0

Explanation

A switch of transmission queue for the channel identified by channel-name is required due to a change to the default cluster transmission queue configuration of the queue manager, or to the cluster channel name attribute of a cluster transmission queue. This message is issued by the channel initiator when the process of switching the transmission queue from old-xmitq to new-xmitq is started.

System action

The queue manager is notified to start the switching process for the channel.

The channel continues to run after closing the old transmission queue and switching to use the new transmission queue instead.

System programmer response

None.

CSQX294E

csect-name Transmission queue status unavailable, channel channel-name

Severity

8

Explanation

The transmission queue for the cluster-sender channel identified by channel-name cannot be determined because when the queue manager started it was unable to load the persisted transmission queue state from the queue SYSTEM.CHANNEL.SYNCQ.

System action

The channel ends abnormally.

System programmer response

If the queue manager is unable to load the persisted transmission queue state during startup it issues message CSQM561E.

CSQX295E

csect-name Cluster transmission queue restricted, channel channel-name, transmission queue xmitq-name

Severity

8

Explanation

The cluster-sender channel identified by channel-name has been configured to use the transmission queue xmitq-name, however, the use of transmission queues other than SYSTEM.CLUSTER.TRANSMIT.QUEUE has subsequently been disabled by the queue manager mode of operation (OPMODE).

System action

The channel ends abnormally.

System programmer response

Ensure the queue manager mode of operation is correctly configured. If the configuration is correct, perform the following actions:

1. Change the default cluster transmission queue configuration of the queue manager so that all cluster-sender channels default to use the transmission queue SYSTEM.CLUSTER.TRANSMIT.QUEUE. We can do this by changing the value of the DEFCLXQ queue manager attribute to SCTQ.
2. Identify any manually defined transmission queues that have a non-blank cluster channel name attribute value by using the DISPLAY QLOCAL(*) WHERE(CLCHNAME NE ' ') command. Change the cluster channel name attribute value of these queues to blank.
3. Restart the channel.

CSQX296E

csect-name Password protection negotiation failed for channel channel-name, connection conn-id

Severity

8

Explanation

The channel channel-name could not be established because it failed to agree a password protection algorithm with the remote machine conn-id.

System action

The channel does not start.

System programmer response

Check whether password protection settings prevent interoperability with the remote machine.

Alternatively, consider using SSL or TLS to protect passwords instead. You must use a non-null CipherSpec to protect passwords.

CSQX403I

csect-name Auto-definition of channel channel-name suppressed by exit exit-name

Severity

0

Explanation

In response to a request to start a channel that was not defined, an attempt was made to define it automatically. The channel auto-definition exit exit-name prevented it being defined.

System action

The channel is not started.

CSQX404I

csect-name Phase one of REFRESH CLUSTER REPOS(YES) has completed, cluster cluster_namen objects changed

Severity

0

Explanation

Phase one of REFRESH CLUSTER has completed.

Applications attempting to access cluster resources may see failures to resolve cluster resources until phase two of REFRESH CLUSTER is complete.

Phase two is complete once all new information has been received from other members of the cluster.

Monitor the SYSTEM.CLUSTER.COMMAND.QUEUE to determine when it has reached a consistently empty state to indicate that the refresh process has completed.

System action

None.

CSQX405I

csect-name FORCEREMOVE QUEUES(YES) command processed, cluster cluster_name target target

Severity

0

Explanation

The repository manager successfully processed a RESET CLUSTER ACTION(FORCEREMOVE) command with the QUEUES(YES) option for the indicated cluster and target queue manager.

System action

None.

CSQX406E

csect-name REFRESH CLUSTER REPOS(YES) command failed, cluster cluster_name - qmgr-name is a full repository

Severity

8

Explanation

The repository manager could not process a REFRESH CLUSTER command with the REPOS(YES) option for the indicated cluster, because the local queue manager provides full repository management service for the cluster.

System action

The command is ignored.

System programmer response

Reissue the command with the correct values or on the correct queue manager. It might be necessary to change the queue manager so that it is not a full repository for the cluster.

CSQX407I

csect-name Cluster queue q-name definitions inconsistent

Severity

4

Explanation

The definition of a cluster queue has different values for the DEFPRTY, DEFPSIST, DEFPRESP, and DEFBIND attributes on the various queue managers in the cluster.

All definitions of the same cluster queue must be identical. Problems might arise if your applications rely on one of these attributes to determine messaging behavior. For example, if an application opens a cluster queue with the option MQOO_BIND_AS_Q_DEF, and the different instances of the queue have different DEFBIND values, the behavior of the message transfer depends on which instance of the queue happens to be selected when it is opened.

System action

None.

System programmer response

Alter the definitions of the queue on the various queue managers so that they have identical values for these attributes.

CSQX410I

csect-name Repository manager started

Severity

0

Explanation

The repository manager started successfully.

System action

None.

CSQX411I

csect-name Repository manager stopped

Severity

0

Explanation

The repository manager stopped. This may be for one of three reasons:

• The channel initiator is stopping.
• The channel initiator is starting and the queues used by the repository manager have not been defined because clustering is not required.
• An error has occurred.

System action

Processing continues, but clustering is not available.

System programmer response

If an error has occurred, investigate the problem reported in the preceding messages.

CSQX412E

csect-name Misdirected repository command, target target-id sender sender-id

Severity

8

Explanation

The repository manager received a command intended for some other queue manager, with an identifier that is target-id. The command was sent by the queue manager with identifier sender-id.

System action

The command is ignored, and the error is reported to the sender.

System programmer response

Check the channel and cluster definitions of the sending queue manager.

CSQX413E

System programmer response

Collect the items listed in the Problem Determination section and contact your IBM support center.

CSQX417I

csect-name Cluster-senders remain for removed queue manager qmgr-name

Severity

0

Explanation

The indicated queue manager has been deleted or forcibly removed from a cluster, but there are manually-defined cluster-sender channels that refer to it. This means that the repository manager will continue to send cluster information to the removed queue manager.

System programmer response

Delete the manually-defined cluster-sender channels that refer to qmgr-name.

CSQX418I

csect-name Only one repository for cluster cluster_name

Severity

0

Explanation

The repository manager has received information about a cluster for which it is the only full repository.

System action

None.

System programmer response

If you require a second full repository, alter the REPOS or REPOSNL attribute of the second queue manager that is to have a full repository for the cluster to specify the cluster name.

CSQX419I

csect-name No cluster-receivers for cluster cluster_name

Severity

0

Explanation

The repository manager has received information about a cluster for which no cluster-receiver channels are known.

System action

None.

System programmer response

Define cluster-receiver channels for the cluster on the local queue manager.

CSQX420I

csect-name No repositories for cluster cluster_name

Severity

0

Explanation

The repository manager has received information about a cluster for which no full repositories are known.

System action

None.

System programmer response

Define a cluster-sender channel for connecting to the queue manager that is the full repository for the cluster, or alter the REPOS or REPOSNL attribute of the queue manager that is to have a full repository for the cluster to specify the cluster name.

CSQX422E

csect-name Repository manager error, RC=return-code

Severity

8

Explanation

An internal error has occurred.

System action

The repository manager attempts to continue processing. Information about the error is written to the data set identified by the CSQSNAP DD statement of the channel initiator started task JCL procedure, xxxxCHIN.

System programmer response

Collect the items listed in the Problem Determination section and contact your IBM support center.

CSQX425E

csect-name Repository command merge error, command code command cluster object object-name sender sender-id

Severity

Explanation

An internal error has occurred.

System action

The command is ignored; the repository manager continues processing. Information about the error is written to the data set identified by the CSQSNAP DD statement of the channel initiator started task JCL procedure, xxxxCHIN.

System programmer response

Collect the items listed in the Problem Determination section and contact your IBM support center.

CSQX426E

csect-name Undeliverable repository command, channel channel-name target target-id command code command

Severity

8

Explanation

The repository manager tried to send a command to another queue manager using channel channel-name. The other queue manager, with identifier target-id, could not be found.

System action

The command is ignored.

System programmer response

Check the channel and cluster definitions of the sending and receiving queue managers.

CSQX427E

csect-name Cluster-sender not connected to repository, cluster cluster_name channel channel-name target target-id

Severity

8

Explanation

A cluster-sender channel must be connected to a queue manager that is a full repository for all the clusters for the channel, and the corresponding cluster-receiver channel must be in the same clusters. Channel channel-name in cluster cluster_name does not satisfy this. target-id is the identifier of the target queue manager for the channel.

System action

The command is ignored.

System programmer response

Check the definition of the channel on both queue managers to ensure that it is connected to a full repository for the clusters, and that it is in the same clusters on both queue managers.

CSQX428E

csect-name Unexpected publication of a cluster queue, cluster cluster_name cluster queue q-name sender sender-id

Severity

8

Explanation

The repository manager received a publication for cluster queue q-name from another queue manager, with an identifier sender-id, relating to cluster cluster_name. The local queue manager cannot accept the command because it is not a full repository for the cluster and thus it does not have an interest in the cluster queue.

This can also occur because a command destined for the local repository manager is delayed in the network and is out of date when it arrives, for example because a REFRESH CLUSTER command has been issued on the local repository manager and caused its view of the cluster to change.

System action

The command is ignored.

System programmer response

If the local partial repository queue manager is supposed to be a full repository for the cluster, use the ALTER QMGR command to specify a repository or repository namelist which contains the cluster. If the local queue manager is correctly a partial repository for the cluster, ensure that the remote queue manager does not have a manually defined cluster sender directed at the local partial repository.

If the message occurs because a command is out of date, the message can be ignored.

CSQX429E

csect-name Unexpected deletion of a cluster queue, cluster cluster_name cluster queue q-name

Severity

8

Explanation

The repository manager received a deletion for cluster queue q-name from another queue manager, with an identifier sender-id, relating to cluster cluster_name. The local queue manager cannot accept the command because it is not a full repository for the cluster and thus it does not have an interest in the cluster queue.

This can also occur because a command destined for the local repository manager is delayed in the network and is out of date when it arrives, for example because a REFRESH CLUSTER command has been issued on the local repository manager and caused its view of the cluster to change.

System action

The command is ignored.

System programmer response

If the local partial repository queue manager is supposed to be a full repository for the cluster, use the ALTER QMGR command to specify a repository or repository namelist which contains the cluster. If the local queue manager is correctly a partial repository for the cluster, ensure that the remote queue manager does not have a manually defined cluster sender directed at the local partial repository.

If the message occurs because a command is out of date, the message can be ignored.

CSQX430E

csect-name Unexpected queue manager repository command, cluster cluster_name channel channel-name sender sender-id

Severity

8

Explanation

The repository manager received a command from another queue manager, with an identifier that is sender-id, relating to cluster cluster_name. The local queue manager cannot accept the command because it is not a full repository for the cluster, it does not have an interest in the cluster channel, and it does not have any matching cluster-sender channels. The cluster-sender channel used by the other queue manager was channel-name.

This message might appear on a queue manager that has defined a cluster-sender channel to another queue manager that does not host a full repository, if the other queue manager is later modified to host a full repository.

System action

The command is ignored.

System programmer response

Check the definition of the channel on the sending queue manager to ensure that it is connected to a full repository for the cluster.

Ensure the CLUSTER and CLUSNL values are consistent, and that we have not specified a cluster_name when you meant a cluster-namelist.

CSQX431I

csect-name Repository unavailable, cluster cluster_name channel channel-name sender sender-id

Severity

0

Explanation

The repository manager received a command from another queue manager, with identifier sender-id, reporting that it is no longer a full repository for cluster cluster_name.

System action

The cluster-sender channel channel-name is changed so that it can no longer be used to access the other queue manager in relation to the cluster.

CSQX432I

csect-name Unexpected cluster query received, cluster cluster_name cluster object object-name sender sender-id

Severity

8

Explanation

The repository manager received a query for cluster object object-name from another queue manager, with an identifier sender-id, relating to cluster cluster_name. The local queue manager cannot accept the command because it is not a full repository for the cluster.

This can also occur because a command destined for the local repository manager is delayed in the network and is out of date when it arrives, for example because a REFRESH CLUSTER command has been issued on the local repository manager and caused its view of the cluster to change.

System action

The command is ignored.

System programmer response

If the local partial repository queue manager is supposed to be a full repository for the cluster, use the ALTER QMGR command to specify a repository or repository namelist which contains the cluster. If the local queue manager is correctly a partial repository for the cluster, ensure that the remote queue manager does not have a manually defined cluster sender directed at the local partial repository.

If the message occurs because a command is out of date, the message can be ignored.

CSQX433E

csect-name Cluster-receiver and cluster-sender differ, cluster cluster_name channel channel-name sender sender-id

Severity

8

Explanation

The repository manager received a command from another queue manager, with identifier sender-id. The cluster-sender channel channel-name on that queue manager is in cluster cluster_name, but the corresponding cluster-receiver channel on the local queue manager is not.

System action

The command is ignored.

System programmer response

Change the definition of the channel so that it is in the same clusters on both queue managers.

CSQX434E

csect-name Unrecognized message on name

Severity

8

Explanation

The channel initiator found a message on one of its queues that either had a format that could not be recognized or did not come from a queue manager or channel initiator.

System action

The message is put on the dead-letter queue.

System programmer response

Examine the message on the dead-letter queue to determine the originator of the message.

CSQX435E

csect-name Unable to put repository manager message, target target-id MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

4

Explanation

The repository manager tried to send a message to SYSTEM.CLUSTER.COMMAND.QUEUE on another queue manager with an identifier that is target-id, but the MQPUT call was unsuccessful.

System action

Processing continues, but repository information may be out of date.

System programmer response

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form).

Check the channel and cluster definitions on the local and target queue managers, and ensure that the channels between them are running.

When the problem is corrected, the repository information will normally be updated automatically. The REFRESH CLUSTER command can be used to be sure that the repository information is up to date.

This error may occur if the REFRESH CLUSTER REPOS(YES) command is issued against a full repository, as the full repository will then be temporarily unable to fulfil requests from other repositories until it has rebuilt the cluster. If there is more than one full repository for the cluster, the problem will resolve itself. If there is only a single full repository for the cluster, the REFRESH CLUSTER command will need to be run against all the other queue managers in the cluster to make them contact the full repository again.

CSQX436E

csect-name Unable to put repository manager message, cluster cluster_name MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

Explanation

The repository manager tried to send a message to SYSTEM.CLUSTER.COMMAND.QUEUE on a queue manager that has the full repository for the specified cluster, but the MQPUT was unsuccessful.

System action

Processing continues, but repository information may be out of date.

System programmer response

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form).

Check the channel and cluster definitions on the local and target queue managers, and ensure that the channels between them are running.

When the problem is corrected, the repository information will normally be updated automatically. The REFRESH CLUSTER command can be used to be sure that the repository information is up to date.

CSQX437E

csect-name Unable to commit repository changes

Severity

4

Explanation

The repository manager tried to commit some updates to the repository but was unsuccessful.

System action

Processing continues, but local repository information might be out of date.

System programmer response

If this occurs when the channel initiator is stopping, it can be ignored because the local repository information will normally be updated automatically when the channel initiator is restarted. If there is an isolated occurrence at other times, use the REFRESH CLUSTER command to bring the local repository information up to date.

If the problem persists, contact your IBM support center.

CSQX438E

csect-name Unable to reallocate messages, channel channel-name MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

csect-name Phase one of REFRESH CLUSTER has completed, cluster cluster_namen objects changed

Severity

0

Explanation

Phase one of REFRESH CLUSTER has completed.

Applications attempting to access cluster resources may see failures to resolve cluster resources until phase two of REFRESH CLUSTER is complete.

Phase two is complete once all new information has been received from other members of the cluster.

Monitor the SYSTEM.CLUSTER.COMMAND.QUEUE to determine when it has reached a consistently empty state to indicate that the refresh process has completed.

System action

None.

CSQX443I

csect-name SUSPEND QMGR command processed, cluster cluster_namen objects changed

csect-name FORCEREMOVE command failed, cluster cluster_name target target is not unique

Severity

8

Explanation

The repository manager could not process a RESET CLUSTER ACTION(FORCEREMOVE) command for the indicated cluster and target queue manager, because there is more than one queue manager with the specified name in the cluster.

System action

The command is ignored.

System programmer response

Reissue the command specifying the identifier (QMID) of the queue manager to be removed, rather than its name.

CSQX455E

csect-name FORCEREMOVE command failed, cluster cluster_name target target not found

Severity

8

Explanation

The repository manager could not process a RESET CLUSTER ACTION(FORCEREMOVE) command for the indicated cluster and target queue manager, because no information about that queue manager was found in the local repository.

System action

The command is ignored.

System programmer response

Reissue the command specifying the correct queue manager name or identifier.

CSQX456I

csect-name Full repository update not received, cluster cluster_name queue q-name (queue manager qmgr-name)

Severity

0

Explanation

The repository manager found a cluster queue that had been used sometime in the last 30 days, and for which updated information should have been received. However, no such information has been received. The queue is q-name in cluster_name, and its queue manager is qmgr-name.

If the queue manager is a partial repository for the queue, the updated information should have been sent from a full repository. If the queue manager is a full repository, the updated information should have been sent from the queue manager on which the queue is defined.

System action

The repository manager keeps information about this queue for a further 60 days from when the error first occurred. If information has not been sent to a full repository then this queue is not used to satisfy any new requests for cluster resources made to this full repository.

System programmer response

If the queue is still required, check that:

• The cluster channels to and from the queue manager that is the full repository for the cluster, and between there and the queue manager where the queue is located, are able to run.
• The repository managers on those queue managers have not ended abnormally.

CSQX457I

csect-name Repository available, cluster cluster_name channel channel-name sender sender-id

Severity

0

Explanation

The repository manager received a command from another queue manager, with identifier sender-id, reporting that it is once again a full repository for cluster cluster_name.

System action

The cluster-sender channel channel-name is changed so that it can be used to access the other queue manager in relation to the cluster.

CSQX458E

csect-name Unable to access repository cache exclusively, TCB= tcb-name has num-registrations outstanding registrations

Explanation

During an operation that requires exclusive access to the cache, another task was found to be registered. If the queue manager finds registrations still exist after waiting for the task to remove its registrations, the queue manager issues this message. The task preventing exclusive access to the repository cache has num-registrations outstanding registrations.

System action

Processing continues.

System programmer response

Determine if this task is still running or terminated. If the task is not running or if the problem persists collect the items listed in the Problem determination on z/OS section and contact your IBM support center.

CSQX459E

csect-name Cluster topic topic-name from qmgr-name rejected due to PSCLUS(DISABLED)

Explanation

Information regarding cluster topic topic-name has been sent to this queue manager over a channel from qmgr-name but the queue manager attribute PSCLUS has been set to DISABLED, indicating that Publish/Subscribe activity is not expected between queue managers in this cluster.

System action

The cluster topic definition is ignored and will not be visible from this queue manager.

System programmer response

To enable publish/subscribe clustering, alter the PSCLUS attribute on all queue managers in the cluster to ENABLED. You may also need to issue REFRESH CLUSTER and REFRESH QMGR commands as detailed in the documentation for the PSCLUS attribute. If you are not using publish/subscribe clusters you should delete the clustered topic object, and ensure PSCLUS is DISABLED on all queue managers.

CSQX460E

csect-name Cluster cache is full

Severity

8

Explanation

No more space is available in the cluster cache area.

System action

The repository manager terminates. The channel initiator will try to restart it after the specified interval.

System programmer response

The problem may be temporary. If it persists, the queue manager must be restarted; this will cause more space to be allocated for the cluster cache area.

Consider changing the cluster cache type system parameter CLCACHE to dynamic, so that more space for the cache will be obtained automatically as required. (If you are using a cluster workload exit, ensure that it supports a dynamic cluster cache.) For information about the system parameters for the CSQ6SYSP macro, see Using CSQ6SYSP.

CSQX461I

csect-name Cluster cache entry corrected, cluster queue manager clusqmgr-name channel channel-name connection conn-id

Explanation

At channel initiator restart, the repository manager found a corrupted entry in the cluster cache. The entry has been corrected.

System action

Processing continues. The cluster channel to which the entry refers, channel-name using connection conn-id, will be available for use.

System programmer response

None. We can verify that the entry was successfully corrected by issuing the command DISPLAY CLUSQMGR(clusqmgr-name) on the queue manager where this message was issued.

CSQX462E

csect-name Cluster cache entry is unusable, cluster queue manager clusqmgr-name channel channel-name connection conn-id

Severity

8

Explanation

At channel initiator restart, the repository manager found a corrupted entry in the cluster cache which could not be corrected.

System action

The corrupted entry is ignored. The cluster channel to which it refers, channel-name using connection conn-id, will not be usable.

System programmer response

The corrupted entry must be corrected and reintroduced by issuing the command

 ALTER CHANNEL(channel-name) CHLTYPE(CLUSRCVR) 

on the cluster queue manager clusqmgr-name. We can verify that the entry was successfully reintroduced by issuing the command DISPLAY CLUSQMGR(clusqmgr-name) on the queue manager where this message was issued.

CSQX463E

csect-name Error accessing cluster cache entry

Severity

8

Explanation

There was an internal error when accessing a cluster cache entry.

System action

Information about the error is written to the data set identified by the CSQSNAP DD statement of the channel initiator started task JCL procedure, xxxxCHIN. The component where the error occurred (message channel agent, repository manager) usually terminates; in some cases, the end result will be that the channel initiator terminates.

System programmer response

Collect the items listed in the Problem Determination section and contact your IBM support center.

CSQX465I

csect-name New cluster topic definition inconsistent, topic topic-name, queue manager identifier qmid, attribute attr

Severity

4

Explanation

The definition of the cluster topic topic-name, defined on queue manager identifier qmid has different attr attribute values than one or more cluster topics that already exist in the cluster cache. The existing topic objects are reported by message CSQX466I.

All definitions of the same cluster topic should be identical; otherwise, problems may arise if our applications rely on one of these attributes to determine messaging behavior. For example, if an application opens a cluster topic and the different instances of the topic have different TOPICSTR values, the behavior of the message transfer depends on which instance of the topic happens to be selected when it is opened.

System action

None.

System programmer response

Alter the definitions of the topic on the various queue managers so that they have identical values for all attributes.

CSQX466I

csect-name Cluster topic definitions inconsistent, topic topic-name, queue manager identifier qmid attribute attr

Severity

4

Explanation

The definition of the cluster topic topic-name, defined on queue manager identifier qmid has different attr attribute value than a cluster topic being added to the cluster cache. The topic object being added is reported by message CSQX465I.

All definitions of the same cluster topic should be identical; otherwise, problems may arise if our applications rely on one of these attributes to determine messaging behavior. For example, if an application opens a cluster topic and the different instances of the topic have different TOPICSTR values, the behavior of the message transfer depends on which instance of the topic happens to be selected when it is opened.

System action

None.

System programmer response

Alter the definitions of the topic on the various queue managers so that they have identical values for all attributes.

CSQX467E

Repository error for topic topic-name, MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

8

Explanation

The cluster repository was unable to insert or delete topic topic-name due to an unexpected error in the queue manager.

System action

The repository manager terminates. The channel initiator tries to restart the repository manager after an interval. See message CSQX448E for more information.

System programmer response

For more information about mqcc and mqrc completion codes (mqrc-text provides the MQRC in textual form), see API completion and reason codes.

Contact your IBM support center with the reason code provided for this failure.

CSQX468I

csect-name Queue manager qmgr-uuid1 has replaced queue manager qmgr-uuid2 in a cluster due to reuse of channel channel-name

Severity

0

Explanation

Queue manager qmgr-uuid1 has joined a cluster using a cluster receiver channel with the same name as one that has already been defined by queue manager qmgr-uuid2. All cluster receiver channels used within a cluster must be uniquely named.

System action

Queue manager qmgr-uuid1 uses channel channel-name. Queue manager qmgr-uuid2 cannot successfully participate in the cluster while queue manager qmgr-uuid1 is a member.

System programmer response

The use of a channel name currently associated with a different queue manager in the cluster can be intentional, for example it is possible the original queue manager has been deleted and re-created as a new queue manager. However, accidental duplication of a channel name across multiple queue managers would also result in this behavior. If this action was not intended review the configuration of the queue managers.

CSQX469E

csect-name Update not received for CLUSRCVR channel channel-name hosted on queue manager qmid in cluster cluster_name, expected n days ago, m days remaining

Severity

8

Explanation

The repository manager detected that the CLUSRCVR channel has not been republished by its owning queue manager. This republish action should have happened automatically n days ago, or in the time between then and now.

System action

The repository manager will check for this condition approximately every hour, continuing for a period of approximately m days from now. If an update for the CLUSRCVR channel is received during this period, these messages will stop. If no update is received, these messages will continue to be written. However, after this period has elapsed, if no update has been received, the local queue manager will discard its knowledge of this channel, and these messages will stop. You should be aware that Partial Repository queue managers in this cluster will cease to be able to use the channel at about that time.

System programmer response

There are several possible responses:

1. If the channel had been removed intentionally, and is no longer required, you should consider removing it fully via the RESET CLUSTER command.
2. There is a long-running problem with the local queue manager's CLUSRCVR in cluster cluster_name. If this is true, then correct the problem urgently, to ensure that updates for the cluster are received.
3. There is a long-running problem on the remote queue manager's CLUSSDR in cluster cluster_name. If this is true, then correct the problem urgently, to ensure that updates for the cluster are sent.
4. Check that the repository manager on the remote queue manager has not ended abnormally.
5. The remote queue manager is out of step with this queue manager, potentially due to a restore of the queue manager from a backup. The remote queue manager must issue REFRESH CLUSTER to synchronize with other queue managers in the cluster.

If the above items have been checked, and this problem persists over several days, causing repeats of this error message in the local queue manager's error logs, contact your IBM support center.

CSQX470E

csect-name Channel channel-name has the wrong disposition disposition

Severity

8

Explanation

The action you requested cannot be performed on channel channel-name because it has the wrong disposition. For example, the action asked for a shared channel, but its disposition is private.

System action

The requested action is not performed.

System programmer response

Check whether the channel name is specified correctly. If it is, check that:

• The channel has been defined correctly
• The transmission queue name identifies the correct queue, and that queue has the required disposition.

The disposition of an instance of a channel is not related to that specified by QSGDISP in the channel definition:

• A sending channel is shared if its transmission queue is shared, and private if it is not.
• A receiving channel is shared if it was started in response to an inbound transmission directed to the queue sharing group, and private if it was started in response to an inbound transmission directed to the queue manager.

CSQX471I

csect-name nn shared channels to restart, nn requests issued

Severity

0

Explanation

The channel initiator is shutting down; it owns some active shared sending channels, and they have not been requested to stop. Requests to restart these channels on another queue manager have been issued as shown.

System action

The channel initiator shutdown processing continues.

System programmer response

If the numbers in the message differ, the channel initiator was not able to issue restart requests for all the channels. In this case, use the DISPLAY CHSTATUS command to determine which channels are still owned by the queue manager for the channel initiator that is shutting down, and which therefore have not been restarted, and restart them manually as required.

CSQX475I

csect-name Channel channel-name adopted, connection conn-id

Severity

0

Explanation

Channel channel-name, which was orphaned because of a communications error, has been adopted by a new instance of the channel, from connection conn-id.

System action

Processing continues.

CSQX476E

csect-name Channel channel-name is active on qmgr-name, shared status entry found

Severity

8

Explanation

An operation was requested on a channel that is active. Because the channel is shared, it might be active on another queue manager. If the channel is a receiver, a previous instance of it might have been orphaned and therefore still be active.

System action

The request fails.

System programmer response

For operations other than starting the channel, either stop the channel manually, or wait for it to terminate, and try the operation again. It might be necessary to use MODE(FORCE) to stop the channel manually if the Adopt MCA function is not being used. Using the Adopt MCA function avoids the need for manual intervention to handle orphaned receiver channels.

If the channel is not running on the named queue manager, then there is an orphaned shared status entry, which mighty be because a loss of connectivity to Db2® occurred. If the problem persists, contact your IBM support center.

CSQX477E

csect-name Channel channel-name is active, transmission queue queue-name in use on qmgr-name

Severity

8

Explanation

An operation was requested on a channel that is active. The queue queue-name named as a transmission queue in the channel definition for channel-name is in use on another member of the queue sharing group, qmgr-name.

System action

The request fails.

System programmer response

Do the following, as appropriate:

• Check if the channel is already running
• Check if another channel is using the queue by using the DISPLAY QSTATUS command
• Ensure the queue name is specified correctly in the channel definition
• Alter the queue usage attribute of the queue to that of a transmission queue.

If the channel is already running, for operations other than starting the channel, either stop the channel manually, or wait for it to terminate, and retry the operation. It may be necessary to use MODE(FORCE) to stop the channel manually if the Adopt MCA function is not being used. Using the Adopt MCA function will avoid the need for manual intervention to handle orphaned receiver channels.

CSQX478E

csect-name Channel channel-name is active on qmgr-name, connection tag in use

Severity

8

Explanation

An operation was requested on a channel that is active. The connection tag used to serialize the channel within the queue sharing group is currently in use. Because the channel is shared, it might be active on another queue manager. If the channel is a receiver, a previous instance of it might have been orphaned and therefore still be active.

In addition to the CSQX478E for a shared channel, another possible symptom is CSQX514E: csect-name Channel channel-name is active on qmgr-name. The new instance of the channel is starting with a different IP address from the running instance. If the sender's IP address changed or might translate into more than one address, set ADOPTCHK to QMNAME using the ALTER QMGR command. For example, /cpf ALTER QMGR ADOPTCHK(QMNAME) where "cpf" is the command prefix for the queue manager subsystem.

System action

The request fails.

System programmer response

For operations other than starting the channel, either stop the channel manually, or wait for it to terminate, and try the operation again. It might be necessary to use MODE(FORCE) to stop the channel manually if the Adopt MCA function is not being used. Using the Adopt MCA function avoids the need for manual intervention to handle orphaned receiver channels.

CSQX479E

csect-name Channel channel-name is active on qmgr-name, shared channel adoption failed

Severity

8

Explanation

An attempt was made to adopt channel channel-name, which was orphaned because of a communications error. It failed, either because the channel could not be stopped or because a response was not received from the queue manager qmgr-name.

System action

The request fails, and the orphaned channel might remain active.

System programmer response

Investigate any preceding error messages to discover why the adopt failed. Either stop the channel manually, or wait for it to terminate, and try the operation again. It might be necessary to use MODE(FORCE) to stop the channel manually.

CSQX482E

csect-name Shared channel function not available

Severity

8

Explanation

During the execution of a channel command, or during shared channel processing, an internal function required by the channel initiator was found to be unavailable.

System action

The channel command fails or the channel stops.

System programmer response

Check that the Db2 tables required by IBM MQ are correctly defined, and restart the queue manager and Db2 if necessary. If these appear to be running correctly, display the information in the shared channel status (CSQ.ADMIN_B_SCST) and the shared synchronization key (CSQ.ADMIN_B_SSKT) Db2 tables, and contact your IBM support center for further assistance. For further information, and for details of a sample job (CSQ45STB) which shows the information in the Db2 tables, see Problem determination on z/OS.

CSQX483E

csect-name Db2 not available

Severity

8

Explanation

Because Db2 is not available, or is no longer available, the channel initiator cannot do processing for a shared channel.

System action

The channel command fails or the channel stops.

System programmer response

Use the preceding messages on the z/OS console to investigate why Db2 is not available, and restart it if necessary.

CSQX484E

csect-name Error accessing Db2

Severity

8

Explanation

Because there was an error in accessing Db2, the channel initiator cannot do processing for a shared channel.

System action

The channel command fails or the channel stops.

System programmer response

Resolve the error reported in the preceding messages.

CSQX485E

csect-name Shared channel status error

Severity

8

Explanation

During the execution of a channel command, or during shared channel processing, shared channel status or shared synchronization key information, held in Db2, was found to be corrupted.

System action

The channel command fails or the channel stops.

System programmer response

Check that the Db2 tables required by IBM MQ are correctly defined, and restart Db2 if necessary. If Db2 appears to be running correctly, display the information in the shared channel status (CSQ.ADMIN_B_SCST) and the shared synchronization key (CSQ.ADMIN_B_SSKT) Db2 tables, and contact your IBM support center for further assistance. For further information, and for details of a sample job (CSQ45STB) which shows the information in the Db2 tables, see Problem determination on z/OS.

CSQX486E

csect-name Shared channel channel-name definitions inconsistent

Severity

8

Explanation

The definition of a shared channel has differing attribute values on the various queue managers in the queue sharing group. For example, if the type of the channel differs start or stop requests cannot operate correctly.

System action

The request fails.

System programmer response

Change the definitions of the channel so that they are the same on all the queue managers. If the channel type needs changing, you must delete and then redefine the channel.

CSQX489E

csect-name Maximum instance limit limit exceeded, channel channel-name connection conn-id

Severity

8

Explanation

There are too many instances of the channel channel-name running to be able to start another. The maximum number allowed is limit and is specified in the MAXINST channel attribute.

System action

The channel does not start.

System programmer response

Wait for some of the operating channels to terminate before restarting the channel, or use the ALTER CHANNEL command to increase MAXINST.

CSQX490E

csect-name Maximum client instance limit limit exceeded, channel channel-name connection conn-id

Severity

8

Explanation

There are too many instances of the channel channel-name running from the connection conn-id to be able to start another. The maximum number allowed is limit and is specified in the MAXINSTC channel attribute.

System action

The channel does not start.

System programmer response

Wait for some of the operating channels to terminate before restarting the channel, or use the ALTER CHANNEL command to increase MAXINSTC.

CSQX496I

csect-name Channel channel-name stopping because of request by remote exit

Severity

0

Explanation

The channel is closing because the user channel exit at the remote end requested it.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off. For auto-defined channels, the channel does not start.

System programmer response

Note that this puts the channel into STOPPED state. A START CHANNEL command must be issued to restart it.

CSQX498E

csect-name Invalid MQCD field field-name, value=nnn (Xxxx)

Severity

8

Explanation

The MQCD structure returned by the channel auto-definition exit had an invalid value in the indicated field. The value is shown in decimal (nnn) and hexadecimal (xxx).

System action

The channel is not defined.

System programmer response

Correct the channel auto-definition exit.

CSQX500I

csect-name Channel channel-name started connection conn-id

Severity

0

Explanation

The specified channel has been started.

If channel-name is an inbound channel (indicated by csect-name containing CSQXRESP) then it was started from connection conn-id. If channel-name is an outbound channel then conn-id will be omitted.

System action

Processing continues.

CSQX501I

csect-name Channel channel-name no longer active connection conn-id

Severity

0

Explanation

Channel channel-name terminated. It is now inactive if it terminated normally when the disconnect interval expired, or stopped if it terminated because of an error or a STOP CHANNEL command.

If channel-name was an inbound channel (indicated by csect-name containing CSQXRESP) then it was started from connection conn-id. If channel-name was an outbound channel then conn-id will be omitted.

System action

Processing continues.

System programmer response

If the channel is stopped, resolve any error, and issue a START CHANNEL command to restart the channel.

CSQX502E

csect-name Action not allowed for channel chl-type(channel-name)

Severity

8

Explanation

The action you requested cannot be performed on channel channel-name. Some actions are only valid for certain channel types. This channel is a chl-type channel type. For example, we can only ping a channel from the end sending the message.

System action

The requested action is not performed.

System programmer response

Check whether the channel name is specified correctly. If it is, check that:

• The channel has been defined correctly
• The connection name identifies the remote end correctly
• For a cluster-receiver channel, the connection name does not specify a generic address
• For TCP/IP connections, the port number specified by the local channel matches that used by the listener at the remote queue manager.

We can use the csect-name to determine the action that failed:

Table 1.

csect-name	action
CSQXPING	PING CHANNEL
CSQXRESE	RESET CHANNEL
CSQXRESO	RESOLVE CHANNEL
CSQXSTOP	STOP CHANNEL

CSQX503E

csect-name Negotiation failed, channel channel-name type=last-segment-type data=xxx connection conn-id

Severity

8

Explanation

Channel channel-name could not be established due to a negotiation failure between the local queue manager and the remote end using connection conn-id. The last control data received was of type last-segment-type and is accompanied by data indicating the error.

A value of FFFFFFFF (-1) indicates that no error data was sent by the remote end.

System action

The channel is not started.

System programmer response

Examine the console log for the remote end for messages explaining the cause of the negotiation failure.

CSQX504E

csect-name Local protocol error, channel channel-name type=type data=xxx

Severity

System programmer response

Examine the console log to determine the cause of the failure. This might occur after the channel initiator or queue manager is stopped forcibly or ends abnormally. If it occurs in other cases, contact your IBM support center to report the problem.

CSQX505E

csect-name Sequence wrap values differ, channel channel-name local=local-seqno remote=remote-seqno

Severity

8

Explanation

The sequence number wrap value for channel channel-name is local-seqno, but the value specified at the remote end is remote-seqno. The two values must be the same before the channel can be started.

System action

The channel does not start.

System programmer response

Change either the local or remote channel definition so that the values specified for the message sequence number wrap value are the same.

CSQX506E

csect-name Message receipt confirmation not received for channel channel-name

Severity

8

Explanation

The remote end did not accept the last batch of messages.

System action

Channel channel-name stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Determine why the remote end did not accept the last batch of messages. Resolve the problem and restart the channel.

CSQX507E

csect-name Channel channel-name is in-doubt, connection conn-id (queue manager qmgr-name)

Severity

8

Explanation

Channel channel-name is in-doubt with the remote end using connection conn-id. The associated remote queue manager is qmgr-name; in some cases its name cannot be determined and so is shown as '????'.

System action

The requested operation does not complete.

System programmer response

Examine the status of the channel, and either restart a channel to resolve the in-doubt state, or use the RESOLVE CHANNEL command to correct the problem manually.

CSQX511I

csect-name Channel channel-name started, connection conn-id

Severity

0

Explanation

The specified SVRCONN channel has been started from connection conn-id.

System action

Processing continues.

CSQX512I

csect-name Channel channel-name no longer active, connection conn-id

Severity

0

Explanation

SVRCONN Channel channel-name terminated. It is now inactive if it terminated normally when the disconnect interval expired, or stopped if it terminated because of an error or a STOP CHANNEL command.

The SVRCONN channel-name was started from connection conn-id.

System action

Processing continues.

System programmer response

If the SVRCONN channel is stopped, resolve any error, and issue a START CHANNEL command to restart the channel.

CSQX513E

csect-name Current channel limit exceeded channel channel-name connection conn-id

Severity

8

Explanation

There are too many channels current to be able to start another. The maximum number allowed is specified in the MAXCHL queue manager attribute. Current channels include stopped and retrying channels as well as active channels.

If channel-name was an inbound channel (indicated by csect-name containing CSQXRESP) then it was started from connection conn-id. If channel-name was an outbound channel then conn-id will be omitted.

System action

The channel does not start.

System programmer response

Wait for some of the operating channels to terminate before restarting the channel, or use the ALTER QMGR command to increase MAXCHL. A change that increases MAXCHL will not be effective until the channel initiator has been stopped and restarted. If many of the currently operating channels are server-connection channels, consider limiting the number of those using MAXINST or MAXINSTC attributes of a server-connection channel. See Server-connection channel limits for more details.

CSQX514E

csect-name Channel channel-name is active on qmgr-name

Severity

8

Explanation

An operation was requested on a channel that is active. If the channel is shared, it might be active on another queue manager. If the channel is a receiver, a previous instance of it might have been orphaned and therefore still be active.

System action

The request fails.

System programmer response

For operations other than starting the channel, either stop the channel manually, or wait for it to terminate, and try the operation again. It might be necessary to use MODE(FORCE) to stop the channel manually if the Adopt MCA function is not being used. Using the Adopt MCA function avoids the need for manual intervention to handle orphaned receiver channels.

CSQX515I

csect-name Channel channel-name changed

Severity

0

Explanation

The channel for which information has been requested is a new instance of the channel. The previous channel instance has ended.

System action

The information shown is for the new channel instance.

CSQX516E

csect-name Error accessing synchronization data, RC=return-code

Severity

8

Explanation

There was an error when accessing the channel synchronization data.

If the return code is of the form 10009nnn or 20009nnn, it is a distributed queuing message code. This is generally associated with message CSQXnnnE, which will normally be issued previously.

Otherwise the most likely cause is a shortage of storage.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

In some cases, the channel initiator will stop as well.

System programmer response

If the return code is a distributed queuing message code, see the corresponding message explanation for more information. Where no such message is described, see Distributed queuing message codes for the corresponding message number.

Restart the channel or the channel initiator. If the problem persists, contact your IBM support center.

CSQX517E

csect-name Error in q-name - channel channel-name repeated

Severity

8

Explanation

There was more than one set of synchronization information in q-name for an instance of channel channel-name. This is probably because the channel is a receiver channel, and there are two sender channels with the same name on different queue managers within the same network address that have communicated with it.

System action

The first set of synchronization information for the channel instance is used, and any others are ignored. Errors may occur if the channel is used.

System programmer response

Avoid using the channel. Remove the extra sets of information from the channel synchronization queue, and rename channels so that they have unique names.

If this does not resolve the problem, contact your IBM support center.

CSQX519E

csect-name Channel channel-name not defined connection remote-conn-id

Severity

8

Explanation

The channel initiator could not find a definition of channel channel-name.

The associated remote connection name is remote-conn-id. If the request to use the channel is not from an inbound connection, or the remote connection name cannot be determined, remote-conn-id will be shown as '????'.

System action

The requested operation fails.

System programmer response

Ensure that the name is specified correctly and the channel definition is available.

The message can also be issued if an automatically defined cluster sender channel (CLUSSDRA) has been deleted as a result of issuing a REFRESH CLUSTER command and a putting application still has a queue object open which is using the channel.

CSQX520E

csect-name Remote channel channel-name not defined

Severity

8

Explanation

There is no definition of channel channel-name at the remote end.

System action

The channel does not start.

System programmer response

Add an appropriate channel definition at the remote end, and retry the operation.

CSQX523E

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off.

System programmer response

Examine the console log for the remote end to determine the cause of the failure. This might occur after the channel initiator or queue manager is stopped forcibly or ends abnormally. If it occurs in other cases, contact your IBM support center.

CSQX524E

csect-name Remote queue manager unavailable for channel channel-name

Severity

8

Explanation

Channel channel-name cannot start because the remote queue manager is not currently available.

System action

The channel does not start

System programmer response

Either start the remote queue manager, or retry the operation later.

CSQX525E

csect-name Channel channel-name closing because remote queue manager qmgr-name is stopping

Severity

8

Explanation

Channel channel-name is closing because the remote queue manager qmgr-name is stopping. In some cases, the remote queue manager name cannot be determined and so is shown as '????'.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off.

System programmer response

Investigate why the remote queue manager is stopping, if it was not expected.

CSQX526E

csect-name Message sequence error for channel channel-name, sent=msg-seqno expected=exp-seqno

Severity

8

Explanation

The local queue manager does not agree with the remote end on the next message sequence number for channel channel-name. The message is normally issued at both the sending and receiving end: at the sending end, msg-seqno and exp-seqno are unpredictable; at the receiving end, a message had sequence number msg-seqno but sequence number exp-seqno was expected.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off.

System programmer response

Determine the cause of the inconsistency. It could be that the synchronization information has become damaged, or has been backed out to a previous version. If the problem cannot be resolved, the sequence number can be reset manually at the sending end of the channel using the RESET CHANNEL command. (For some queue managers, it might be necessary to issue the RESET CHANNEL command at the receiving end as well.)

CSQX527E

csect-name Unable to send message for channel channel-name

Severity

8

Explanation

The remote end cannot receive the message that is being sent for channel channel-name.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Examine the console log for the remote end to determine why the message cannot be received, and then restart the channel.

CSQX528I

csect-name Channel channel-name stopping

Severity

0

Explanation

The channel is closing because a STOP CHANNEL command was issued, or because the channel initiator is stopping.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Note that a STOP CHANNEL command puts the channel into STOPPED state. A START CHANNEL command must be issued to restart it.

CSQX531E

csect-name Transmission queue q-name for channel-name has wrong usage type

Severity

8

Explanation

Queue q-name is named as a transmission queue in the channel definition for channel-name, but it is not a transmission queue.

System action

The channel does not start.

System programmer response

Ensure the queue name is specified correctly in the channel definition. If it is, alter the queue usage attribute of the queue to that of a transmission queue.

CSQX533I

csect-name Channel channel-name is already in requested state

Severity

0

Explanation

A request to stop channel channel-name was made, but the channel was already in the specified state, or in the process of reaching that state.

System action

The request is ignored.

CSQX534E

csect-name Channel channel-name is stopped

Severity

4

Explanation

The operation requested cannot be performed because the channel is currently stopped.

System action

The request is ignored.

System programmer response

Issue a START CHANNEL command to restart the channel.

CSQX535E

csect-name Channel channel-name stopping because exit exit-name is not valid

Severity

8

Explanation

The user exit exit-name specified for channel channel-name is not valid.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off. For auto-defined channels, the channel does not start.

System programmer response

Ensure that the user exit name is specified correctly in the channel definition, and that the user exit program is correct and available. The channel initiator loads exits from the library data sets under the CSQXLIB DD statement of its started task JCL procedure xxxxCHIN.

CSQX536I

csect-name Channel channel-name stopping because of request by exit exit-name

Severity

0

Explanation

The channel is closing because the user channel exit exit-name requested it.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off. For auto-defined channels, the channel does not start.

System programmer response

Note that this puts the channel into STOPPED state. A START CHANNEL command must be issued to restart it.

CSQX539E

csect-name Channel channel-name for queue q-name is not available

Severity

8

Explanation

A trigger message was received to start a channel channel-name to process the transmission queue q-name. However, the channel initiator could not find a defined and available channel to start.

System action

The channel does not start.

System programmer response

Ensure that there is a channel defined to process the transmission queue, and that it is not stopped.

CSQX540E

csect-name Unable to commit batch, channel channel-name MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

8

Explanation

An MQCMIT call for the queue associated with channel channel-name was unsuccessful.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off.

System programmer response

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form).

CSQX541E

csect-name Invalid CCSIDs for data conversion, ccsid1 and ccsid2

Severity

8

Explanation

Either the local coded character set identifier (CCSID) or the target CCSID is not valid, or is not currently supported, or conversion between the two CCSIDs involved is not supported. (The name of the channel cannot be determined because the invalid CCSID prevents the necessary data conversion being done.)

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Ensure that the CCSIDs are valid and that conversion between them is supported. For information about the CCSIDs that are supported, see Codeset names and CCSIDs.

CSQX544E

csect-name Messages for channel channel-name sent to remote dead-letter queue

Severity

4

Explanation

During the processing of channel channel-name, one or more messages have been put the dead-letter queue at the remote queue manager.

System action

Processing continues.

System programmer response

Examine the contents of the dead-letter queue. Each message is contained in a structure that describes why the message was put to the queue, and to where it was originally addressed.

CSQX545I

csect-name Channel channel-name closing because disconnect interval expired

Severity

0

Explanation

The channel is closing because no messages arrived on the transmission queue within the disconnect interval.

System action

The channel ends normally.

CSQX547E

csect-name Remote channel channel-name has the wrong type

Severity

8

Explanation

The operation requested cannot be performed because channel channel-name on the remote end is not of a suitable type. For example, if the local channel is defined as a sender the remote queue manager must define its corresponding channel as either a receiver or requester.

System action

The requested operation is not performed.

System programmer response

Check that the channel name is specified correctly. If it is, check that:

• The channel definition on the remote end has an appropriate channel type
• The connection name of the local channel identifies the remote end correctly
• For cluster channels, the connection names do not specify a generic address
• For TCP/IP connections, the port number specified by the local channel matches that used by the listener at the remote queue manager.

CSQX548E

csect-name Messages sent to local dead-letter queue, channel channel-name reason=mqrc (mqrc-text)

Severity

4

Explanation

During the processing of channel channel-name, one or more messages have been put the dead-letter queue at the local queue manager. mqrc shows why, and is one of the following:

• an MQRC_* reason code from an MQPUT or MQPUT1 call
• an MQFB_* feedback code.

System action

Processing continues.

System programmer response

Examine the contents of the dead-letter queue. Each message is contained in a structure that describes why the message was put to the queue, and to where it was originally addressed.

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form).

For information about MQFB_* feedback codes see the MQMD description in MQMD - Message descriptor.

CSQX549E

csect-name Queue q-name for channel channel-name is get-inhibited

Severity

8

Explanation

An MQGET failed because the transmission queue had been previously inhibited for gets.

System action

The channel stops. The associated transmission queue might have triggering turned off.

System programmer response

Change the definition of the transmission queue so that it is not inhibited for MQGET calls.

CSQX551E

csect-name Action not supported, channel channel-name connection conn-id (queue manager qmgr-name)

Severity

8

Explanation

The operation requested for channel channel-name is not supported by the remote end using the connection conn-id. The associated remote queue manager is qmgr-name; in some cases its name cannot be determined and so is shown as '????'.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Check that the connection name parameter is specified correctly and that the levels of the queue managers in use are compatible.

CSQX552E

csect-name Security exit data for channel channel-name not received, connection conn-id

Severity

8

Explanation

The local security user channel exit for channel channel-name requested data from the remote security user channel exit, but no data was received. The remote connection was conn-id.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Ensure that the security exit for the channel on the remote end has been defined correctly and is available. If it is, check that the exit program operates correctly.

CSQX558E

csect-name Remote channel channel-name not available

Severity

8

Explanation

The channel channel-name at the remote end is currently stopped or is otherwise unavailable. For example, there might be too many channels current to be able to start it.

System action

The channel does not start.

System programmer response

This might be a temporary situation, and the channel will try again. If not, check the status of the channel at the remote end. If it is stopped, issue a START CHANNEL command to restart it. If there are too many channels current, either wait for some of the operating channels to terminate, or stop some channels manually, before restarting the channel.

CSQX565E

csect-name No dead-letter queue for qmgr-name, channel channel-name

Severity

8

Explanation

A message could not be delivered normally and there is no dead-letter queue defined for queue manager qmgr-name.

We can get this message with a cluster sender channel during message reallocation. During reallocation, the message is got from the transmission queue and put back again. If the transmission queue is full, then the put fails and tries writing the message to the dead letter queue. If the dead letter queue does not exist, message CSQX565E is produced, and the reallocation changes are rolled back. Reallocation does not happen until the queue full problem is resolved.

System action

The channel stops, except in the case where nonpersistent messages are being sent and the NPMCLASS attribute of the channel is set to FAST, when processing continues. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Correct the problem that prevented the message from being delivered normally, or define a dead-letter queue for the remote queue manager.

CSQX567E

csect-name Listener unable to register to APPC/MVS, TRPTYPE=LU62 INDISP=disposition RC=return-code reason=reason

Severity

8

Explanation

While starting, the specified LU 6.2 listener could not register as an APPC/MVS server. The return code from APPC/MVS allocate services was return-code and the associated reason code was reason (both in hexadecimal).

System action

The listener is not started.

System programmer response

See Communications protocol return codes for the cause of the return code from APPC/MVS allocate services, and the Writing Servers for APPC/MVS manual for more information. Check that the LUNAME queue manager attribute is the same as the PARTNER_LU value for the APPC/MVS symbolic destination used by the listener.

CSQX568E

csect-name Listener unable to unregister from APPC/MVS, TRPTYPE=LU62 INDISP=disposition RC=return-code reason=reason

Severity

8

Explanation

While stopping, the specified LU 6.2 listener could not unregister as an APPC/MVS server. The return code from APPC/MVS allocate services was return-code and the associated reason code was reason (bothin hexadecimal).

System action

The listener stops. It may not be possible to restart it.

System programmer response

See Communications protocol return codes for the cause of the return code from APPC/MVS allocate services and the Writing Servers for APPC/MVS manual for more information.

CSQX569E

csect-name Channel channel-name exceeded TCP/IP channel limit

Severity

8

Explanation

The number of current TCP/IP channels is the maximum allowed; another channel cannot be started. Current channels include stopped and retrying channels as well as active channels. The maximum allowed is specified in the TCPCHL queue manager attribute, but may be reduced if a dispatcher fails, or if TCP/IP resources are restricted (as reported by message CSQX118I).

System action

The channel does not start.

System programmer response

If the maximum allowed is zero, TCP/IP communications are not allowed, and no TCP/IP channels can be started. If the maximum allowed is non-zero, wait for some of the operating channels to terminate before restarting the channel, or use the ALTER QMGR command to increase TCPCHL.

CSQX570E

csect-name Channel channel-name exceeded LU 6.2 channel limit

Severity

8

Explanation

The number of current LU 6.2 channels is the maximum allowed; another channel cannot be started. Current channels include stopped and retrying channels as well as active channels. The maximum allowed is specified in the LU62CHL queue manager attribute, but may be reduced if a dispatcher fails.

System action

The channel does not start.

System programmer response

If the maximum allowed is zero, LU 6.2 communications are not allowed, and no LU 6.2 channels can be started. If the maximum allowed is non-zero, wait for some of the operating channels to terminate before restarting the channel, or use the ALTER QMGR command to increase LU62CHL.

CSQX571E

csect-name Error from PKCS #11 callable service 'func', RC=return-code, reason=reason

Severity

8

Explanation

An attempt to use PKCS #11 callable service func failed.

System action

The component where the error occurred (message channel agent, supervisor) will continue but the feature being used will be unavailable.

If func is CSFPPRF (Pseudo-random function) the feature affected is password protection. If this feature is not being used then this error can be ignored. If this occurs at channel initiator startup, the password protection algorithm uses STCK instead.

System programmer response

For information about the return-code and reason from the PKCS #11 callable service, see the section on ICSF and cryptographic coprocessor return and reason codes in the z/OS Cryptographic Services ICSF Application Programmer's Guide.

For more information about Integrated Cryptographic Service Facility (ICSF), see Use ICSF.

CSQX572E

csect-name Channel channel-name stopping because message header is not valid

Severity

8

Explanation

During the processing of channel channel-name, a message was found that had an invalid header. The dead-letter queue was defined as a transmission queue, so a loop would have been created if the message had been put there.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Correct the problem that caused the invalid message header.

CSQX573E

csect-name Channel channel-name exceeded active channel limit

Severity

8

Explanation

There are too many channels active (transmitting messages) to be able to start another. The maximum number allowed is specified in the ACTCHL queue manager attribute.

System action

The channel does not start.

System programmer response

Either wait for some of the operating channels to terminate, or stop some channels manually, before restarting the channel, or use the ALTER QMGR command to increase ACTCHL. A change that increases ACTCHL will not be effective until the channel inititator has been stopped and restarted.

CSQX574I

csect-name Channel channel-name can now start

Severity

0

Explanation

The specified channel was waiting to start, because there were too many channels active (transmitting messages) to be able to start another. One or more of the active channels has terminated, so this channel can now start.

Note: This message is not itself issued, although the corresponding event is generated.

CSQX575E

csect-name Negotiation failed for channel

Severity

8

Explanation

A channel between the local queue manager and the remote end could not be established due to a negotiation failure. The failure was such that the channel name could not be determined: for example, data conversion between the coded character set identifiers (CCSIDs) used by the local and remote ends might not have been possible.

System action

The channel is not started.

System programmer response

Examine the console log for the remote end for messages explaining the cause of the negotiation failure.

CSQX576E

csect-name ICSF is not available

Severity

8

Explanation

In order to generate entropy for the password protection algorithm, a call to CSFPPRF (Pseudo-random function) is made which requires the Integrated Cryptographic Service Facility (ICSF) to be available. ICSF was found not to be available.

System action

The password protection algorithm uses STCK instead.

System programmer response

If password protection is being used, start ICSF. If it is not being used, this error message can be ignored.

CSQX578E

csect-name Unable to save status for channel channel-name

Severity

8

Explanation

An internal error has occurred.

System action

The channel stops. The associated transmission queue may be set to GET(DISABLED) and triggering turned off.

System programmer response

Collect the items listed in the Problem Determination section and contact your IBM support center.

CSQX599E

csect-name Channel channel-name ended abnormally connection conn-id

Severity

8

Explanation

Channel channel-name ended abnormally because of a severe problem, as reported in the preceding messages.

If channel-name is an inbound channel (indicated by csect-name containing CSQXRESP) then it was started from connection conn-id. If channel-name is an outbound channel then conn-id will be omitted.

System action

The channel stops. The associated transmission queue might be set to GET(DISABLED) and triggering turned off.

System programmer response

Investigate the problem reported in the preceding messages. For more information see, Problem determination in DQM.

CSQX608E

csect-name Remote resources in recovery for channel channel-name

Severity

8

Explanation

Channel channel-name cannot start because resources at the remote queue manager are being recovered.

System action

The channel does not start.

System programmer response

Restart the channel at a later time. If the problem persists examine the console log for the remote end for messages explaining the cause of the problem. This includes an instance of CSQX609E with more details.

CSQX609E

csect-name Resources in recovery, channel channel-name MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

8

Explanation

The message channel agent for the channel could not connect to the queue manager because resources are being recovered.

System action

The channel does not start.

System programmer response

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form), which come from an MQCONNX request.

CSQX613I

csect-name Channel channel-name instance is already in requested state

Severity

0

Explanation

A request to stop a particular instance of channel channel-name was made (by specifying a connection name or a remote queue manager name), but the channel instance was already in the specified state, or in the process of reaching that state.

This error will also apply if an attempt is made to stop a SVRCONN channel using the QMNAME parameter. In this case do not use the QMNAME parameter. In order to stop a specific SVRCONN instance use the CONNAME parameter

System action

The request is ignored.

CSQX617I

csect-name SSL key repository refresh not processed, SSL communications unavailable

Severity

0

Explanation

The cached SSL key repository cannot be refreshed in response to a REFRESH SECURITY TYPE(SSL) command because SSL communications are currently unavailble.

System action

0

System programmer response

Investigate why SSL is not available and take action as appropriate. It may be necessary to restart the channel initiator to allow SSL to be used.

CSQX618I

csect-name SSL key repository refresh started

Severity

0

Explanation

The cached SSL key repository is being refreshed in response to a REFRESH SECURITY TYPE(SSL) command.

System action

Message CSQX619I will be issued when the refresh is complete.

CSQX619I

CSQX620E

csect-name System SSL error, channel channel-name connection conn-id function 'func' RC=return-code

Severity

8

Explanation

An unexpected SSL communications error occurred for a channel. The channel is channel-name; in some cases its name cannot be determined and so is shown as '????'. The remote connection is conn-id. func is the name of the System SSL function that gave the error, and return-code is the return code (in decimal unless func is 'gsk_fips_state_set' in which case it is in hexadecimal).

System action

The channel is stopped.

System programmer response

See Transport Layer Security (TLS) return codes for z/OS for the cause of the return code from System SSL and refer to the z/OS Cryptographic Services System SSL Programming - SSL Function Return Codes for more information.

CSQX625E

csect-name System SSL error, function 'func' RC=return-code

Severity

8

Explanation

An unexpected SSL communications error occurred for an SSL server subtask. func is the name of the System SSL function that gave the error, and return-code is the return code (in decimal).

System action

The SSL server subtask terminates.

System programmer response

See Transport Layer Security (TLS) return codes for z/OS for the cause of the return code from System SSL and the System Secure Sockets Layer Programming Guide and Reference manual for more information.

CSQX629E

csect-name Channel channel-name requires ICSF for SSLCIPH(ciph)

Severity

8

Explanation

Channel channel-name is using a cipherspec ciph that requires Integrated Cryptographic Service Facility (ICSF) callable services, but ICSF is not available. Sometimes the channel name and cipherspec are unknown and so are shown as "????". If known, the cipherspec is shown in the message as a 4-character code.

Recognized values are shown in message CSQX631E.

The cipherspecs that use GCM or ephemeral elliptic curve algorithms require ICSF.

System action

The channel will not start.

System programmer response

Ensure ICSF is available, or change the cipherspec that the channel is using to one that does not require ICSF. If you are using ICSF and running the queue manager with SSLFIPS(YES), ensure that ICSF is configured to run in FIPS mode.

For more information, see System SSL RC 455.

CSQX630E

csect-name Channel channel-name requires SSL

Severity

8

Explanation

Channel channel-name cannot start because it requires SSL, but SSL communications are not currently available.

System action

The channel does not start.

System programmer response

If SSL is required, investigate why it is not available and take action as appropriate. One possible cause, is that there is no certificate available owned by the user who initiated the channel address space. If this is the case, you need to re-configure the user ID to have a certificate with the correct value, by issuing the command RACDCERT ID(xxxx), where xxxx is the user ID.

Check that we have the SSL queue manager properties set, for example SSLTASKS must be greater than 0.

If SSL is not required, change the channel definition so that SSL is not used.

CSQX631E

csect-name Cipher specifications differ, channel channel-name local=local-ciph (local-protocol) remote=remote-ciph (remote-protocol) connection conn-id

Severity

8

Explanation

The SSL cipher specification value for channel channel-name is local-ciph using protocol local-protocol, but the value specified at the remote end (from connection conn-id) is remote-ciph using protocol remote-protocol. The cipher specification and protocol values must be the same before the channel can be started. The cipher specification values are shown in the message as four-character codes; common values are:

Table 2. Convert from four-character codes to CipherSpec names

Four-character code	Protocol	CipherSpec name
0001	SSL 3.0	NULL_MD5

System action

The channel does not start.

System programmer response

Change either the local or remote channel definition so that the values specified for the SSL cipher specification are the same.

CSQX632I

csect-name SSL certificate has no associated user ID, remote channel channel-name, connection conn-id - channel initiator user ID used

Severity

0

Explanation

The certificate sent from the remote end (from connection conn-id) during SSL handshaking was accepted, but no user ID could be found associated with it. The channel is channel-name; in some cases its name cannot be determined and so is shown as '????'.

Likely causes are that the certificate or a matching certificate name filter are defined to the external security manager (ESM), or that the certificate contains fields that are not understood by the ESM.

System action

The user ID of the channel initiator address space is used as the channel user ID for the channel.

System programmer response

If you are using certificate name filtering, we can create a filter that matches this certificate. See Working with Certificate Name Filters (CNFs) for details on associating a user ID with a certificate.

If the security you want on your channel does not require the use of the SSL mapped certificate user ID, we can define the channel to use Put Authority (PUTAUT) with a value of ONLYMCA instead of DEF, or ALTMCA instead of CTX and this message is not issued as no security checking for the channel is using the SSL mapped certificate user ID that could not be found. See Receiving channels using TCP/IP for more details about which user IDs are used for security checking on a receiving channel using TCP/IP.

Alternatively, change the SSLPEER channel attribute or create a CHLAUTH record to prevent this certificate being accepted from the remote channel. See Channel authentication records for more details.

CSQX633E

csect-name SSL certificate for remote channel channel-name failed local check, connection conn-id

Severity

8

Explanation

The certificate sent from the remote end (from connection conn-id) during SSL handshaking could not be validated. The channel is channel-name; in some cases its name cannot be determined and so is shown as '????'.

System action

The channel will not start.

System programmer response

Ensure that the SSL certificate connected to the key repository at the remote end is valid, and that the signing certificate(s) have been connected to the key ring on the local queue manager so that the certificate sent can be authenticated.

For full details about SSL certificates and key repositories see Securing.

This error might indicate that the remote end of the channel is configured to send the wrong certificate. Check the certificate label configuration at the remote end of the channel and ensure that the local key repository contains all of the necessary CA certificates.

For more information, refer to System SSL RC 8.

CSQX634E

csect-name SSL certificate failed remote check, channel channel-name connection conn-id

Severity

8

Explanation

The certificates sent to the remote end using the connection conn-id during SSL handshaking could not be validated. The channel is channel-name; in some cases its name cannot be determined and so is shown as '????'.

System action

The channel will not start.

System programmer response

Firstly, you need to check that the SSL certificate in the key ring at the local queue manager qmgr-name is valid, for example, in TRUST status and not expired.

Secondly, you also need to check that both the signing certificate (for example the certificate from the certificate authority) and the signed certificate have been connected to the key repository on the remote end, so that the certificate sent can be verified at the remote end.

The certificate used is either named on the channel in the CERTLABL attribute, or named on the queue manager in the CERTLABL attribute or CERTQSGL attribute (for a shared channel). If no certificate label is found in any of these attributes, then the certificate is named 'ibmWebSphereMQqsg-name' (for a shared channel) or 'ibmWebSphereMQqmgr-name', or a default certificate in the key ring is used.

For full details about SSL certificates and key repositories see Securing.

For more information, refer to System SSL RC 414.

CSQX635E

Explanation

The SSL cipher specification value for channel channel-name is not valid. The value is shown in the message as the full cipher string.

Recognized values are shown in message CSQX631E.

This error can occur if the remote end is configured to use SSLFIPS(YES). Check the errors at the remote end to determine if this is the case.

System action

The channel will not start.

System programmer response

Correct the SSL cipher specification for the channel. If the remote end is configured to only accept FIPS-certified cipher specifications, change the channel to use a FIPS-certified cipher spec. See Specifying CipherSpecs for details on which cipher specifications are FIPS-certified.

For more information, refer to System SSL RCs 402, 412 and 422.

CSQX636E

csect-name Distinguished name does not match peer name, channel channel-name name='dist-name' connection conn-id

Severity

8

Explanation

The distinguished name, dist-name, specified in the SSL certificate at the remote end (from connection conn-id) does not match the SSL peer name for channel channel-name. The distinguished name at the remote end must match the peer name specified (which can be generic) before the channel can be started. In some cases the channel name cannot be determined and so is shown as '????'.

System action

The channel will not start.

System programmer response

This error might indicate that the remote end of the channel is configured to send the wrong certificate. Check the certificate label configuration at the remote end of the channel and ensure that the local key repository contains all of the necessary CA certificates.

To allow this remote end to connect, change the SSL peer name specification for the channel so that it matches the distinguished name in the SSL certificate at the remote end, or obtain the correct certificate for the remote end, as appropriate.

If the SSL Peer name specification needs to match a number of different distinguished names for multiple different remote SSL certificates, consider using channel authentication records to define rules to allow or block specific SSL peer names instead of the SSL Peer name specification on the channel definition. See Channel authentication records for more details.

CSQX637E

csect-name No SSL certificate for remote channel channel-name, connection conn-id

Severity

8

Explanation

csect-name No SSL certificate for channel channel-name

Severity

8

Explanation

The channel channel-name did not supply a certificate to use during SSL handshaking, but a certificate is required by the remote end. In some cases the channel name cannot be determined and so is shown as '????'.

System action

The channel does not start.

System programmer response

Ensure that the key ring of the local queue manager qmgr-name has an SSL certificate connected to it which is associated with the queue manager. If we have configured a certificate label, check that the certificate exists.

The certificate used is either named on the channel in the CERTLABL attribute, or named on the queue manager in the CERTLABL attribute or CERTQSGL attribute (for a shared channel). If no certificate label is found in any of these attributes, then the certificate is named 'ibmWebSphereMQqsg-name' (for a shared channel) or 'ibmWebSphereMQqmgr-name', or a default certificate in the key ring is used.

Alternatively, if appropriate, change the remote channel definition so that its SSLCAUTH attribute is set to OPTIONAL.

In some cases this message will appear multiple times, once for each affected channel.

System action

The channel does not start.

System programmer response

Ensure that the SSL/TLS certificate named cert-label is in the key ring and that it is valid, and that the queue manager is running with OPMODE(NEWFUNC,800).

Alternatively, change the certificate label configuration so that the channel uses a valid certificate.

The certificate used is either named on the channel in the CERTLABL attribute, or named on the queue manager in the CERTLABL attribute or CERTQSGL attribute (for a shared channel). If no certificate label is found in any of these attributes, then the certificate is named 'ibmWebSphereMQqsg-name' (for a shared channel) or 'ibmWebSphereMQqmgr-name', or a default certificate in the key ring is used.

To verify which key ring is in use, issue the following MQSC command:

DISPLAY QMGR SSLKEYR

To list the certificates that are present in the key ring in use, issue the following RACF® command, or an equivalent command in your External Security Manager:

RACDCERT ID(chinit-user-id) LISTRING(key-ring-name)

csect-name Channel channel-namespecified a weak or broken SSL CipherSpec sslciph

Severity

8

Explanation

The channel is unable to start because it is configured to use a CipherSpec that is potentially insecure.

System action

The channel is prevented from starting.

System programmer response

Examine the CipherSpec specified in the SSLCIPH parameter and consider using a more secure CipherSpec.

If you want to re-enable the use of weak CipherSpecs, we can do so by adding a dummy Data Definition (DD) statement named CSQXWEAK to the channel initiator JCL. For example:

//CSQXWEAK DD DUMMY

If you want to re-enable the disabled SSLv3 support in IBM MQ, we can do so by adding a dummy Data Definition (DD) statement named CSQXSSL3 to the channel initiator JCL. For example:

//CSQXSSL3 DD DUMMY

You need to specify both of the preceding dummy DD statements, if you want to enable a weak SSLv3-based CipherSpec.

There are alternative mechanisms that can be used to forcibly re-enable weak CipherSpecs, and SSLv3 support,if the Data Definition change is unsuitable. Contact IBM Service for further information.

Attention: Re-enabling CipherSpecs in this manner leaves systems exposed to possible security problems. You should use CipherSpecs that use only the TLS protocol, rather than SSLv3.

Examine the channel authentication records to ensure that the correct settings have been configured. If the channel authentication record was not in warning mode the channel would be blocked. The ALTER QMGR CHLAUTH switch is used to control whether the channel authentication records are used. The DISPLAY CHLAUTH command can be used to query the channel authentication records.

CSQX787I

csect-name Channel channel-name from ipaddress would have been blocked due to USERSRC(NOACCESS), Detail: detail

Severity

4

Explanation

The inbound channel channel-name would have been blocked from address ipaddress because the active values of the channel matched a channel authentication record configured with USERSRC(NOACCESS). It was not blocked due to the channel authentication record being in warning mode.

The active values of the channel were detail.

System action

The channel is started.

System programmer response

Examine the channel authentication records to ensure that the correct settings have been configured. If the channel authentication record was not in warning mode the channel would be blocked. The ALTER QMGR CHLAUTH switch is used to control whether the channel authentication records are used. The DISPLAY CHLAUTH command can be used to query the channel authentication records.

CSQX788I

csect-name DNS lookup for address address using function 'func' took n seconds

Severity

4

Explanation

An attempt to resolve address address using the 'func' function call took n seconds to complete. This might indicate a problem with the DNS configuration.

System action

Processing continues.

System programmer response

Ensure that the DNS is correctly configured on the local system.

If the address was an IP address then the slow operation was a reverse DNS lookup. Some DNS configurations are not capable of reverse DNS lookups and some IP addresses have no valid reverse DNS entries.

If the problem persists, consider disabling reverse DNS lookups until the issue with the DNS can be resolved.

CSQX790I

csect-name Connection authentication failed for user user-id due to CHLAUTH with CHCKCLNT(chckclnt-value), Detail: detail

Severity

4

Explanation

The user ID user-id and its password were checked because the inbound connection matched a channel authentication record with CHCKCLNT(chckclnt-value).

The active values of the channel were detail. The MATCH(RUNCHECK) mode of the DISPLAY CHLAUTH command can be used to identify the relevant CHLAUTH record.

This message accompanies a previous error to clarify the reason for the user ID and password check.

System action

The channel is not started.

System programmer response

Refer to the previous error for more information.

Ensure that a password is specified by the client application and that the password is correct for the User ID.

Alternatively, to avoid the authentication check we can amend the CHLAUTH record CHCKCLNT attribute. However, allowing unauthenticated remote access is not recommended.

CSQX791E

csect-name Client application appl-name from address ip-address did not supply a user ID and password, Detail: detail

Severity

8

Explanation

The client application appl-name running on host ip-address did not supply a user ID and password. The channel authentication (CHLAUTH) record for the connection requires a user ID and password, but none was supplied.

The active values of the channel were detail. The MATCH(RUNCHECK) mode of the DISPLAY CHLAUTH command can be used to identify the relevant CHLAUTH record.

System action

The channel is not started.

System programmer response

Ensure that the application provides a valid user ID and password, or change the queue manager connection authority (CONNAUTH) configuration to OPTIONAL to allow client applications to connect which have not supplied a user ID and password.

CSQX793E

csect-name The user ID and password for client application appl-name from address ip-address cannot be checked, Detail: detail

Severity

8

Explanation

The user ID and password for the client application appl-name running on host ip-address cannot be checked. The channel authentication (CHLAUTH) record for the connection requires an authentication check, but the queue manager is not configured to use connection authentication for clients.

The active values of the channel were detail. The MATCH(RUNCHECK) mode of the DISPLAY CHLAUTH command can be used to identify the relevant CHLAUTH record.

System action

The channel is not started.

System programmer response

Change the CHLAUTH configuration so that client authentication is not required, or alter the queue manager connection authority (CONNAUTH) configuration to enable client authentication checks.

CSQX797E

csect-name Unable to send message for channel channel-name, MQCC=mqcc MQRC=mqrc (mqrc-text)

Severity

8

Explanation

The send on channel channel-name could not be completed and the message could not be redirected to the dead-letter queue.

System action

The channel stops.

System programmer response

Refer to API completion and reason codes for information about mqcc and mqrc (mqrc-text provides the MQRC in textual form) to determine why the send failed.

Refer to previous messages to determine why the dead-letter queue is not available.

CSQX875I

csect-name REFRESH CLUSTER processing started for cluster cluster-name

Severity

0

Explanation

A REFRESH CLUSTER command has been issued on this queue manager.

In phase one this will discard all locally cached information for the cluster and request new information from other members of the cluster when necessary. Phase two processes the information received. For large cluster configurations this process can take a significant amount of time, especially on full repository queue managers. During this time applications attempting to access cluster resources may see failures to resolve cluster resources. In addition, cluster configuration changes made on this queue manager may not be processed until the refresh process has completed.

System action

Defer any cluster related work on this queue manager until both phases are complete.

Message CSQX442I or CSQX404I will be issued at the end of phase one.

Completion of phase two can be determined when the SYSTEM.CLUSTER.COMMAND.QUEUE has reached a consistently empty state.

CSQX876I

csect-name Conflicting clustered topic topic-name from queue manager qmgr-name

Severity

8

Explanation

A conflict has been detected for clustered topic topic-name.

Two clustered topics conflict if any of the following conditions are true:

1. They have the same topic string but have a different topic name
2. They have the same topic string, or one is an ancestor of the other in the topic tree, and they have a different cluster name
3. They have the same topic string, or one is an ancestor of the other in the topic tree, and they have incompatible values for the cluster route attribute

System action

The CLSTATE attribute of the clustered topic identified by topic-name is set to INVALID and the topic is no longer used by the queue manager.

System programmer response

Review the clustered topics visible to the queue manager and correct any conflicts by modifying or deleting the definitions in error. After updating the topic definitions, ensure all clustered topics have a CLSTATE of ACTIVE on all queue managers in the same cluster.
