Does the problem affect only shared queues?

Use this topic to investigate possible queue sharing group issues which can cause problems for shared queues.

If the problem affects only queue sharing groups, use the VERIFY QSG function of the CSQ5PQSG utility. This command verifies that the Db2 setup is consistent in terms of the bitmap allocation fields, and object definition for the Db2 queue manager, structure, and shared queue objects, and reports details of any inconsistency that is discovered.

The following is an example of a VERIFY QSG report with errors:
