Shared queue problems

Problems occur if IBM MQ discovers that a page set based queue, and a shared queue of the same name are defined.

Symptoms

IBM MQ issues the following message:

CSQI063E +CSQ1 QUEUE queue-name IS BOTH PRIVATE AND SHARED

During queue manager restart, IBM MQ discovered that a page set based queue and a shared queue of the same name coexist.

System action

Once restart processing has completed, any MQOPEN request to that queue name fails, indicating the coexistence problem.

System programmer action

None.

Operator action

Delete one version of the queue to allow processing of that queue name. If there are messages on the queue that must be kept, we can use the MOVE QLOCAL command to move them to the other queue.
