Local fix
Set MONQ attribute to off.
Problem summary
When a queue status is inquired via a wild card, the amqzlaa0 process servicing the request will attempt to cache certain inter process communication data. Queue status inquiries will create requests which have matching keys for data retrieval causing access to the cached data, as the target object name is not verified.
Problem conclusion
The product has been changed to verify that the cached reply is for the requested queue object. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.1 8.1.0.10 The latest available maintenance can be obtained from 'Recommended Fixes for IBM MQ' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'IBM MQ planned maintenance release dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
