Problem summary
**************************************************************** USERS AFFECTED: Users of the SYSTEM.CLUSTER.HISTORY.QUEUE may be affected by this problem. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: The SYSTEM.CLUSTER.HISTORY.QUEUE (SCHQ) was introduced in IBM MQ version 7.0.1 (https://www.ibm.com/support/pages/new-queue-introduced-refresh- pack-websphere-mq-701-called-systemclusterhistoryqueue). The default expiry for messages put to this queue is documented at 150 days, which consists of: [Cluster object lifetime (90 days)] + [2 * Cluster 'grace' period (2*30 days)] Expiry time is expressed in tenths of a second but a coding error meant that the expiry time for messages on this queue were set as if they were seconds. Dumping a message from the SCHQ shows that the expiry is out by a factor of 10: (dmpmqmsg output) A EXP 12959201 = 14.999 days
Problem conclusion
The code was corrected so that the expiry for messages on the SCHQ matches the documented 150 days. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 LTS 9.1.0.9 v9.2 LTS 9.2.0.3 v9.x CD 9.2.3 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 ---------------------------------------------------------------
