Error description
IBM MQ was upgraded from a 32-bit (prior to v8) to a 64-bit MQ version on a Windows server. Attempts to start and migrate a clustered queue manger fails. A summary of the FDCs after the queue manager fails to start are as follows: Probe Id :- ZF228010 Component :- zfuHealthCheckECThread Major Errorcode :- xecP_E_INVALID_PID MQM Function Stack zfuHealthCheckECThread xcsFFST * Probe Id :- ZX152010 Component :- zmuHealthCheckECThread Major Errorcode :- xecP_E_INVALID_PID MQM Function Stack zmuHealthCheckECThread xcsFFST * Probe Id :- ZX165061 Component :- zmuUtilityManager Major Errorcode :- xecP_E_INVALID_PID MQM Function Stack amqzmuc0 zmuUtilityManager xcsFFST * Probe Id :- ZX165131 Component :- zmuUtilityManager Major Errorcode :- zrcE_UNEXPECTED_ERROR MQM Function Stack amqzmuc0 zmuUtilityManager xcsFFST * Further examination of the FDCs shows that the invalid PID is reported for the Execution controller process (amqzxma0.exe). MQ trace of the amqzxma0.exe process ends with: ----------} zxcRestoreObjectClqMgrExtractInf (rc=OK) ----------{ zxcRestoreObjectClqMgrMigration -----------{ xcsGetMemFn
Local fix
Problem summary
**************************************************************** USERS AFFECTED: 32bit WebSphere MQ server clustered queue managers migrating to a 64bit version of MQ, for example , WebSphere MQ prior to version 8 migrating to a later IBM MQ version, on Windows platforms. Platforms affected: Windows **************************************************************** PROBLEM DESCRIPTION: Due to a programming error in the 32 to 64 bit migration code, the execution controller process (amqzxma0.exe) may terminate with an unhandled memory access violation during the cluster migration process when the queue manager cluster list contains more than 6 entries.
Problem conclusion
The MQ 32 to 64bit cluster migration code within the MQ queue manager has been updated to allocate sufficient memory to migrate the entire cluster list. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.8 v9.0 CD 9.0.4 v9.0 LTS 9.0.0.2 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 ---------------------------------------------------------------
