Problem summary
**************************************************************** USERS AFFECTED: Users who de-register durable subscriptions and then re- register subscriptions using the same subscription name. Platforms affected: All Distributed (iSeries, all Unix and Windows) **************************************************************** PROBLEM SUMMARY: MQ stores details of subscribers in MQ queues. At broker restart the queue is browsed to recreate a memory image of the subscription state. The messages were not being read from the queue in the same order as they were being written, and in some circumstances a sequence of subscribe ; unsubscribe ; subscribe could be replayed as subscribe ; subscribe ; unsubscribe In these cases the second subscription will be detected as invalid and the PU294005 FDC will be raised.
Problem conclusion
The code was changed such that the subscription messages are replayed at broker restart in the same order as those subscription messages were originally written. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v6.0 Platform Fix Pack 6.0.2.9 -------- -------------------- Windows U200313 AIX U828012 HP-UX (PA-RISC) U827381 HP-UX (Itanium) U827383 Solaris (SPARC) U827693 Solaris (x86-64) U828055 iSeries tbc_p600_0_2_9 Linux (x86) U827380 Linux (x86-64) U827694 Linux (zSeries) U827590 Linux (Power) U827382 Linux (s390x) U827695 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 ---------------------------------------------------------------
