Has WebSphere MQ for z/OS run successfully before?

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

• Check your setup

  If WebSphere 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 the WebSphere MQ for z/OS System Setup Guide for guidance on doing this.

• Verify the installation

• Check that message CSQ9022I was issued in response to the START QMGR command (indicating normal completion).

• Ensure that z/OS displays WebSphere MQ as an installed subsystem. Use the z/OS command

  D OPDATA to do this.

• 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.
