Are the correct queues defined?
IBM MQ requires certain predefined queues. Problems can occur if these queues are not defined correctly.
Check that the system-command input queue, the system-command reply model queue, and the reply-to queue are correctly defined, and that the MQOPEN calls were successful.
If we are using the system-command reply model queue, check that it was defined correctly.
If we are using clusters, we need to define the SYSTEM.CLUSTER.COMMAND.QUEUE to use commands relating to cluster processing.
