Is there a problem with the IBM MQ queues?

Use this topic for investigating potential problems with IBM® MQ queues.

If you suspect that there is a problem affecting the queues on your subsystem, use the operations and control panels to display the system-command input queue.

If the system responds

If the system responds, then at least one queue is working. In this case, follow the procedure in Are some of your queues working?.

If the system does not respond

The problem might be with the whole subsystem. In this instance, try stopping and restarting the queue manager, responding to any error messages that are produced.

Check for any messages on the console needing action. Resolve any that might affect IBM MQ, such as a request to mount a tape for an archive log. See if other subsystems or CICS® regions are affected.

Use the DISPLAY QMGR COMMANDQ command to identify the name of the system command input queue.

If the problem still occurs after restart

Contact your IBM support center for help (see Contacting IBM Software Support ).
