Has IBM MQ for z/OS run successfully before?

Knowing whether IBM MQ for z/OS has successfully run before can help with problem determination, and there are checks we can perform to help you.

If the answer to this question is No, consider the following:

• Check your setup.

  If IBM MQ has not run successfully on z/OS before, it is likely that you have not yet set it up correctly. See the information about installing and customizing the queue manager in Installing the IBM MQ for z/OS product for further guidance.

• Verify the installation.
• Check that message CSQ9022I was issued in response to the START QMGR command (indicating normal completion).
• Ensure that z/OS displays IBM MQ as an installed subsystem. To determine if IBM MQ is an installed subsystem use the z/OS command D OPDATA.
• Check that the installation verification program (IVP) ran successfully.
• Issue the command DISPLAY DQM to check that the channel initiator address space is running, and that the appropriate listeners are started.
