Local fix
Problem summary
**************************************************************** USERS AFFECTED: All users of IBM MQ and likely when the queue depth is high. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: An error condition when compacting queue file data structures during shutdown was not correctly handled. This led to a failure to check that there was sufficient log space available to continue with the compaction. If the log space was exhausted during queue compaction, the potential existed for the queue file being compacted to become damaged.
Problem conclusion
The queue manager's queue compaction routines has been modified to add an additional check during queue compaction. This is an extension of checks added previously under APAR IT16268, which fixed a separate logic error in queue compaction routines that might cause object damage. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.11 v9.0 LTS 9.0.0.5 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 ---------------------------------------------------------------
