Note:

1. IBM MQ for z/OS supports queue depth events on shared queues. We 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 Event message MQMD (message descriptor) for more information.
