createWMQConnectionFactory command


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

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

This command is valid only when it is used with WAS V7 and later appservers. Do not use it with earlier versions.

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

print AdminTask.help('WMQAdminCommands')

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

print AdminTask.help('command_name')

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

AdminConfig.save()

-pollingInterval

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 value is 5000.

-rescanInterval

When a message consumer in the point-to-point domain uses a message selector to select which messages it wants to receive, the JMS client searches the WebSphere 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.

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.

The default value is true.
