MQOPEN option for queue manager quiescing
In the CICS environment on z/OS™, if you use the MQOPEN call when the queue manager is in a quiescing state, the call always fails. In other z/OS environments, i5/OS, Windows systems and in UNIX systems environments, the call fails when the queue manager is quiescing only if you use the MQOO_FAIL_IF_QUIESCING option of the MQOPEN call.
