APAR status
Closed as program error.
Error description
Using IBM MQ, Version 8.0.0.4 on AIX 7.1, expiration report messages do not reach their destination. The report messages go to the dead letter queue of the queue manager with reason code 2082 MQRC_UNKNOWN_ALIAS_BASE_Q (Unknown alias base queue). The destination queue for the report messages is an alias queue with a base queue in an MQ cluster. . This happens in MQ Version 8.0 only. With older WebSphere MQ Versions like 7.0, 7.1 or 7.5 this configuration works. .
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Uses attempting to send report messages using an alias queue definition that has a target queue which is a remote member of the cluster that the local queue manager is also a member of. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: In previous versions of the product, it was specified when report messages were / were not permitted to resolve to objects that resided within a cluster configuration remote from the local queue manager. The options were removed in IBM MQ V8 and a calculation performed to determine the routing. In some cases, these calculations prevented name resolution to take place in accordance to the document Queue Name Resolution table in the Application Programming Guide specifically for report messages.
Problem conclusion
the change made to IBM MQ V8 has been reversed to enable the correct name resolution to take place in line with the Application Programming Guides Name Resolution table ( http://www.ibm.com/support/knowledgecenter/SSFKSJ_8.0.0/com.ibm. mq.dev.doc/q025990_.htm?lang=en ) --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 v9.0 CD 9.0.5 v9.0 LTS 9.0.0.3 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' 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 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
