Notes:

  1. WebSphere MQ for z/OS supports queue depth events on shared queues. You might receive a NULL event message for a shared queue if a queue manager has performed no activity on that shared queue.

  2. For shared queues, the correlation identifier, CorrelId in the message descriptor (MQMD) is set. See MQMD (message descriptor) for more information.
