Problem summary
**************************************************************** USERS AFFECTED: Queue managers ended normally or abnormally when transactions are active are affected by this problem. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: When replaying log records during startup the queue manager detected two end-transaction log records for the same transaction. When the second one was replayed the queue manager flagged it as an error and the restart failed. While this scenario is not expected during normal MQ operation, this response was incorrect, as the queue manager should be able to tolerate this condition and continue with the restart.
Problem conclusion
MQ has been modified to tolerate two end-transaction log records for the same transaction so that the queue manager will not fail during restart. An informational FDC with Probe Id AT098010 from atmReinstateTransaction will be generated when processing the second transaction log record. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.1 7.1.0.8 v7.5 7.5.0.6 v8.0 8.0.0.4 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 ---------------------------------------------------------------
