MQBACK - Back out changes
The MQBACK call indicates to the queue manager that all the message gets and puts that have occurred since the last syncpoint are to be backed out. Messages put as part of a unit of work are deleted; messages retrieved as part of a unit of work are reinstated on the queue.
- On z/OS, this call is used only by batch programs (including IMS batch DL/I programs).
- On i5/OS, this call is not supported for applications running in compatibility mode.
