Error description
WebSphere MQ V6 or V7 queues become "missing" from clusters. Application calls to MQOPEN (sometimes MQPUT1, MQPUT) suffer queue name lookup errors (Examples: 2085, 2082) when they try to access the affected cluster queues.

Problem summary
**************************************************************** USERS AFFECTED: This problem can affect systems in which a Full Repository has recently changed the list of clusters in which it hosts a Full Repository, or has ceased to be a Full Repository. It has also been seen to affect systems in which REFRESH CLUSTER has been run on a Full Repository queue manager. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM DESCRIPTION: At the point in time when a new Full Repository (FR) queue manager ceases to host a Full Repository for a particular cluster, details of this change are sent to Partial Repository (PR) queue managers, which then perform some processing. The processing includes an enumeration over all subscriptions previously made by this PR to this FR, and some processing of these subscriptions takes place. For each such subscription, if it is determined that an insufficient set of subscriptions would remain after deleting it, then up to 2 new subscriptions are made via other CLUSSDR channels for a FR or FRs in that cluster. If such subscriptions were ever needed then the new subscriptions made at this point in time were MISSING a vital piece of information. This information prevented the newly made subscriptions being used properly to refresh the knowledge of the queues to which they referred.
Problem conclusion
The WebSphere MQ product code has been corrected such that, in the scenario above, subscriptions that are made will HAVE the vital piece of information they need. They will then function correctly to refresh the knowledge of the queues to which they referred. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v6.0 Platform Fix Pack 6.0.2.12 -------- -------------------- Windows U200331 AIX U842074 HP-UX (PA-RISC) U842208 HP-UX (Itanium) U842213 Solaris (SPARC) U842209 Solaris (x86-64) U842216 iSeries tbc_p600_0_2_12 Linux (x86) U842210 Linux (x86-64) U842215 Linux (zSeries) U842211 Linux (Power) U842212 Linux (s390x) U842214 v7.0 Platform Fix Pack 7.0.1.9 -------- -------------------- Windows U200337 AIX U849391 HP-UX (PA-RISC) U849723 HP-UX (Itanium) U849728 Solaris (SPARC) U849724 Solaris (x86-64) U849730 iSeries 7.0.1.9 Linux (x86) U849725 Linux (x86-64) U849729 Linux (zSeries) U849726 Linux (Power) U849727 v7.1 Platform Fix Pack 7.1.0.2 -------- -------------------- Windows 7.1.0.2 AIX 7.1.0.2 HP-UX (Itanium) 7.1.0.2 Solaris (SPARC) 7.1.0.2 Solaris (x86-64) 7.1.0.2 iSeries 7.1.0.2 Linux (x86) 7.1.0.2 Linux (x86-64) 7.1.0.2 Linux (zSeries) 7.1.0.2 Linux (Power) 7.1.0.2 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 ---------------------------------------------------------------
