Invalidation of object handles (MQRC_OBJECT_CHANGED)

 

If the attributes of an object are found to have changed after the object is opened, the queue manager invalidates the object handle with MQRC_OBJECT_CHANGED on its next use.

Intra-group queuing introduces the following new rules for object handle invalidation :

• If the SYSTEM.QSG.TRANSMIT.QUEUE was included in the name resolution path during open processing because intra-group queuing was ENABLED at open time, but intra-group queuing is found to be DISABLED at put time, then the queue manager invalidates the object handle and fails the put request with MQRC_OBJECT_CHANGED.

• If the SYSTEM.QSG.TRANSMIT.QUEUE was not included in the name resolution path during open processing because intra-group queuing was DISABLED at open time, but intra-group queuing is found to be ENABLED at put time, then the queue manager invalidates the object handle and fails the put request with MQRC_OBJECT_CHANGED.

• If the SYSTEM.QSG.TRANSMIT.QUEUE was included in the name resolution path during open processing because intra-group queuing was enabled at open time, but the SYSTEM.QSG.TRANSMIT.QUEUE definition is found to have changed by put time, then the queue manager invalidates the object handle and fails the put request with MQRC_OBJECT_CHANGED.
