No error messages issued

If no error messages have been issued, perform the following procedure to determine what is causing the problem:

  1. Issue the z/OS commands
    DISPLAY A,xxxxMSTR
    DISPLAY A,xxxxCHIN
    (where xxxx is the WebSphere MQ for z/OS subsystem name). If you receive a message telling you that the queue manager or channel initiator has not been found, this indicates that the subsystem has terminated. This could be caused by an abend or by operator shutdown of the system.
  2. If the subsystem is running, you will receive message IEE105I. This message includes the CT=nnnn field, which contains information about the processor time being used by the subsystem. Note the value of this field, and reissue the command.
