createWMQConnectionFactory command

Use the createWMQConnectionFactory command to create a connection factory for the IBM MQ messaging provider at a specific scope.

To run the command, use the AdminTask object of the wsadmin scripting client.

(iSeries) The wsadmin scripting client is run from Qshell. See topic "Configure Qshell to run WebSphere Application Server scripts".

This command is valid only when it is used with WAS v7 and later application servers. Do not use it with earlier versions.

For a list of the available IBM MQ messaging provider administrative commands, plus a brief description of each command, enter at the wsadmin prompt:

print AdminTask.help('WMQAdminCommands')

For overview help on a given command, enter at the wsadmin prompt:

print AdminTask.help('command_name')

After using the command, save the changes to the master configuration. For example.

AdminConfig.save()

Use the createWMQConnectionFactory command to create an IBM MQ messaging provider connection factory at a specific scope.

We cannot create an IBM MQ messaging provider connection factory under either of the following conditions:

• An IBM MQ messaging provider connection factory already exists with the same name, at the same scope.

• The JNDI name clashes with another entry in WAS JNDI.

Target object

The scope of the IBM MQ messaging provider at which the IBM MQ messaging provider connection factory is to be created.

Required parameters

-name

The administrative name assigned to this IBM MQ messaging provider connection factory.

-jndiName

The name and location used to bind this object into WAS JNDI.

-type

Use this parameter to determine whether a unified connection factory, a queue connection factory or a topic connection factory is to be created.

Enter one of the following values:

• CF
• QCF
• TCF

CF is the default value.

If we specify QCF, we cannot specify any of the following parameters:

• -brokerCtrlQueue
• -brokerSubQueue
• -brokerCCSubQueue
• -brokerVersion
• -brokerPubQueue
• -tempTopicPrefix
• -pubAckWindow
• -subStore
• -stateRefreshInt
• -cleanupLevel
• -sparesSubs
• -wildcardFormat
• -brokerQmgr
• -clonedSubs
• -msgSelection

If we specify TCF, we cannot specify any of the following parameters:

• -msgRetention
• -rescanInterval
• -tempQueuePrefix
• -modelQueue
• -replyWithRFH2

Optional parameters

-description

An administrative description assigned to the connection factory.

-ccdtUrl

A URL to a client channel definition table to use, for this connection factory, when contacting IBM MQ.

Use this parameter to create a ccdtURL connection factory

Do not specify this parameter in conjunction with the following parameters: -qmgrName, -qmgrHostname, -qmgrPortNumber, -qmgrSvrconnChannel, -wmqTransportType or -localAddress.

-ccdtQmgrName

A queue manager name, used to select one or more entries from a client channel definition table.

Do not specify this parameter in conjunction with the following parameters: -qmgrName, -qmgrHostname, -qmgrPortNumber, -qmgrSvrconnChannel, -wmqTransportType, or -localAddress.

-qmgrName

The name of the queue manager to use, for this connection factory, when connecting with IBM MQ.

Use this parameter to create a generic connection factory.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

-wmqTransportType

This parameter determines the way in which a connection is established to IBM MQ for this connection factory.

Use this parameter to create a generic connection factory.

Enter one of the following values:

• BINDINGS
• BINDINGS_THEN_CLIENT
• CLIENT

The default is BINDINGS_THEN_CLIENT.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

For more information about configuring a transport type of BINDINGS_THEN_CLIENT or BINDINGS, refer to Configure the IBM MQ messaging provider with native libraries information.

-qmgrHostname

The host name to use, for this connection factory, when attempting a client mode connection to IBM MQ. It must be a valid TCP/IP host name or IPv4 or IPv6 address.

The default is the local host.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

For information on setting the -qmgrHostname parameter in conjunction with the -connectionNameList parameter, see the description of the -connectionNameList parameter.

-qmgrPortNumber

The port number to use, for this connection factory, when attempting a client mode connection to IBM MQ.

Enter an integer value in the range 1 - 65536 (inclusive).

The default is 1414.

Do not specify this parameter in conjunction with the following parameters: -ccdtUrl or -ccdtQmgrName.

For information on setting the -qmgrPortNumber parameter in conjunction with the -connectionNameList parameter, see the description of the -connectionNameList parameter.

-connectionNameList

The connection name list specifying the host name and port details to use when we want the connection factory to connect to a multi-instance queue manager.

We must only use the -connectionNameList parameter to allow a connection to a multi-instance queue manager. Using the -connectionNameList parameter to connect to a non-multi-instance queue manager can jeopardize transaction integrity.

The -connectionNameList parameter must be entered as a comma separated list of host names and ports in the following format:

host(port),host(port)

For host enter a valid TCP/IP host name, IPv4 or IPv6 address.

For port enter an integer value between 1 and 65536 (inclusive). Specifying a value for port is optional. When we do not specify a value, port defaults to 1414.

For example: localhost(1234),remotehost1(1234),remotehost2

When we specify the -connectionNameList parameter, the -qmgrHostname and -qmgrPortNumber parameters are automatically set to the host name and port number of the first entry in the connection name list. This overrides any values that we previously specified in the -qmgrHostname and -qmgrPortNumber parameters.

In the preceding example this would mean that -qmgrHostname would be localhost and -qmgrPortNumber would be 1234.

The -connectionNameList parameter is only valid for use in WAS v8.0 or later. Attempting to specify the -connectionNameList parameter on an IBM MQ messaging provider connection factory which is defined at a server or node scope running on a version of WAS earlier than v8.0 results in an error message when running the following commands:

• createWMQConnectionFactory
• modifyWMQConnectionFactory

If an IBM MQ messaging provider connection factory based on a connection name list is used by an application client or server running a version of WAS earlier than v8.0, the -connectionNameList information is not used. Instead, the values specified in the -qmgrHostname and -qmgrPortNumber are used, and are set to the relevant values from the first entry in the connectionNameList parameter.

We must not specify the connectionNameList parameter in conjunction with the -ccdtUrl or -ccdtQmgrName parameters.

If we use the-connectionNameList parameter with a centrally managed SSL configuration, the host name and port number information used to select the appropriate SSL configuration is based on the first entry in the connection name list, regardless of which entry in the list is actually used to connect to the queue manager. This is because each instance of a multi-instance queue manager should be using the same SSL configuration, for a given server connection channel, regardless of which instance is actually running.

For more information on using multi-instance queue managers see the IBM MQ information center.

The default is YES.

-pollingInterval

This property is applicable in the client container only.

If each message listener within a session has no suitable message on its queue, this parameter is the maximum interval, in milliseconds, that elapses before each message listener tries again to get a message from its queue. If it frequently happens that no suitable message is available for any of the message listeners in a session, consider increasing the value of this parameter.

The default is 5000.

-rescanInterval

When a message consumer in the point-to-point domain uses a message selector to select which messages it is to receive, the JMS client searches the IBM MQ queue for suitable messages in the sequence determined by the MsgDeliverySequence attribute of the queue. When the client finds a suitable message and delivers it to the consumer, the client resumes the search for the next suitable message from its current position in the queue. The client continues to search the queue in this way until it reaches the end of the queue, or until the interval of time in milliseconds, as determined by the value of this -rescanInterval parameter has expired. In each case, the client returns to the beginning of the queue to continue its search, and a new time interval commences

This parameter must be a positive integer value.

The default is 5000.

-ccsid

The coded character set identifier (CCSID) to be used on connections.

The value of this parameter must be a positive integer. See the IBM MQ messaging provider connection factory advanced properties for more details.

-failIfQuiescing

This parameter determines the behavior of certain calls to the queue manager when the queue manager is put into quiescing state.

The value of this parameter must be true or false.

true specifies that calls to certain methods fail if the queue manager is in a quiescing state. If an application detects that the queue manager is quiescing, the application can complete its immediate task and close the connection, allowing the queue manager to stop.

false specifies that no methods fail if the queue manager is in a quiescing state. If we specify this value, an application cannot detect that the queue manager is quiescing. The application might continue to perform operations against the queue manager, and therefore prevent the queue manager from stopping.

Default is true.

-brokerCtrlQueue

The name of the broker control queue to use if this connection factory is to subscribe to a topic.

The default is SYSTEM.BROKER.CONTROL.QUEUE.

The value of this parameter must be true or false

The default is false.

-brokerQmgr

The name of the queue manager running the broker, if it is not the same as the queue manager to which the connection factory connects.

There is no default value.

-clonedSubs

This parameter determines whether two or more instances of the same durable topic subscriber can run simultaneously

The value of this parameter must be ENABLED or DISABLED

The default is DISABLED.

-customProperties

Specify custom properties to be passed to the IBM MQ messaging provider connection factory implementation. Typically, custom properties are used to set attributes of the connection factory that are not directly supported through the WebSphere administration interfaces.

Each custom property is specified using name and value table step parameters. Since these are table steps, the order of the two parameters is fixed, so we must always specify the name first and the value second:

Minimal connection factory definition

In the following examples, code blocks beginning with wsadmin> show code that is entered by the user. Lines that do not begin with wsadmin> show code that has been returned by the console.

The following example creates an connection factory, specifying the minimum number of parameters. Due to the default values assumed for the unspecified parameters, applications using this connection factory expect to be co-located with a queue manager installed on the same node.

• Use Jython:
