- Whether IBM MQ Advanced extended capabilities are
available for a queue manager.
On z/OS, the queue manager sets the value to be
ENABLED, only if the value of QMGRPROD is
ADVANCEDVUE. For any other value of QMGRPROD, or if
QMGRPROD is not set, the queue manager sets the value to
DISABLED. If ADVCAP is ENABLED we must be
entitled to IBM MQ Advanced for z/OS Value Unit Edition (VUE). See START QMGR on z/OS and Installing IBM MQ Advanced for z/OS Value Unit Edition for more information.
On other platforms, the queue manager sets the value to be
ENABLED, only if you have installed Managed File Transfer, XR, Advanced Message Security
or RDQM. If we have not installed Managed File Transfer, XR, Advanced Message Security or RDQM, ADVCAP is set to
DISABLED. If ADVCAP is ENABLED, we must be
entitled to IBM MQ Advanced. The list of installable
components that enable ADVCAP might change in future releases. for more
information, see IBM MQ components and features and Installing IBM MQ Advanced for Multiplatforms.

can contain the values of zero or more attributes as pairs of attribute name and value in the form
NAME(VALUE).
- DEADQ
- The name of the queue
to which messages are sent if they cannot be routed to their correct destination (the dead-letter
queue or undelivered-message queue). The default is blanks. For example, messages are put on this
queue when:
- A message arrives at a queue manager, destined for a queue that is not yet defined on that queue
manager
- A message arrives at a queue manager, but the queue for which it is destined cannot receive it
because, possibly:
- The queue is full
- The queue is inhibited for puts
- The sending node does not have authority to put the message on the queue
- An exception message must be generated, but the queue named is not known to that queue
manager
Note: Messages that have passed their expiry time are not transferred to this queue when they are
discarded.
If the dead-letter queue is not defined, or full, or unusable for some other reason, a message
that would have been transferred to it by a message channel agent is retained instead on the
transmission queue.
If a dead-letter queue or undelivered-message queue is not specified, all blanks are returned for
this parameter.
- DEFCLXQ
-
The DFTCLXQ attribute controls which transmission queue is selected by default by cluster-sender channels to get messages from, to send the messages to cluster-receiver channels.
- SCTQ
-
All cluster-sender channels send messages from
SYSTEM.CLUSTER.TRANSMIT.QUEUE. The correlID of messages placed on
the transmission queue identifies which cluster-sender channel the message is destined for.
SCTQ is set when a queue manager is defined. This behavior is
implicit in versions of IBM WebSphere MQ, earlier than Version 7.5. In earlier versions, the queue manager attribute
DEFCLXQ was not present.
- CHANNEL
- Each cluster-sender channel sends messages from a different transmission queue.
Each transmission queue is created as a permanent dynamic queue from the model queue
SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE.
If the queue manager attribute, DEFCLXQ, is set to
CHANNEL,the default configuration is changed to cluster-sender channels being associated with individual cluster transmission queues. The transmission queues are permanent-dynamic queues created from the model queue SYSTEM.CLUSTER.TRANSMIT.MODEL.QUEUE. Each transmission queue is associated with one cluster-sender channel. As one cluster-sender channel services a cluster transmission queue, the transmission queue contains messages for only one queue manager in one cluster. We can configure clusters so that each queue manager in a cluster contains only one cluster queue. In this case, the message traffic from a queue manager to each cluster queue is transferred separately from messages to other queues.

- LU62CHL
- The maximum number of channels that can be current, or clients that can be connected,
that use the LU 6.2 transmission protocol. If the value of LU62CHL is zero, the LU 6.2 transmission

- PSMODE
- Controls whether the
publish/subscribe engine and the queued publish/subscribe interface are running, and therefore
controls whether applications can publish or subscribe by using the application programming
interface and the queues that are monitored by the queued publish/subscribe interface.
- PSNPMSG
- If the queued
publish/subscribe interface cannot process a non-persistent input message it might attempt to write
the input message to the dead-letter queue (depending on the report options of the input message).
If the attempt to write the input message to the dead-letter queue fails, and the MQRO_DISCARD_MSG
report option was specified on the input message or PSNPMSG=DISCARD, the broker discards the input
message. If PSNPMSG=KEEP is specified, the interface only discards the input message if the
MQRO_DISCARD_MSG report option was set in the input message.
- PSNPRES
- If the queued
publish/subscribe interface attempts to generate a response message in response to a non-persistent
input message, and the response message cannot be delivered to the reply-to queue, this attribute
indicates whether the interface tries to write the undeliverable message to the dead-letter queue or
whether to discard the message.
- PSRTYCNT
- When the queued
publish/subscribe interface fails to process a command message under sync point (for example a
publish message that cannot be delivered to a subscriber because the subscriber queue is full and it
is not possible to put the publication on the dead letter queue), the unit of work is backed out and
the command tries this number of times again before the broker attempts to process the command
message according to its report options instead.
- PSSYNCPT
- If this attribute
is set to IFPER, when the queued publish/subscribe interface reads a publish or
delete publication messages from a stream queue during normal operation then it specifies
MQGMO_SYNCPOINT_IF_PERSISTENT. This value makes the queued pubsub daemon receive non-persistent
messages outside sync point. If the daemon receives a publication outside sync point, the daemon
forwards that publication to subscribers known to it outside sync point.

generated unique name of the queue manager.
- QMNAME
- The name of the
local queue manager. See Rules for

- SCYCASE
- Whether the security profiles are uppercase or mixed case.
This parameter is valid
only on z/OS.
If this parameter has been altered but the REFRESH SECURITY command has not
yet been issued, the queue manager might not be using the case of profiles you expect. Use
DISPLAY SECURITY to verify which case of profiles is actually in use.
- SPLCAP
-
Indicates if Advanced Message Security (AMS) capabilities are available to the queue manager.
If the AMS component is installed for the
version of IBM MQ that the queue manager is running
under, the attribute has a value ENABLED. If the AMS component is not installed, the value is
DISABLED.
- SQQMNAME
- When a queue manager makes an MQOPEN call for a shared queue and the queue manager that
is specified in the ObjectQmgrName parameter of the MQOPEN call is in the same
queue sharing group as the processing queue manager, the SQQMNAME attribute
specifies whether the ObjectQmgrName is used or whether the processing queue
manager opens the shared queue directly.
This parameter is valid only on z/OS.
- SSLCRLNL
- Indicates the
namelist of AUTHINFO objects being used for the queue manager for certificate revocation checking.
Only authentication information objects with types of
LDAPCRL or OCSP are allowed in the namelist referred to by
SSLCRLNL. Any other type results in an error message when the list is processed
and is subsequently ignored.
