Transactional recovery
When an application issues an MQBACK call or terminates abnormally (for example, because of an EXEC CICS ROLLBACK or an IMS abend) thread-level information stored in the queue manager ensures that the in-flight unit of work is rolled back. MQPUT and MQGET operations within syncpoint on shared queues are rolled back in the same way as updates to non-shared queues.
