Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users creating a queue manager or ending a queue manager very soon after starting it. Platforms affected: AIX, HP-UX Itanium, IBM iSeries, Linux on Power, Linux on S390, Linux on x86-64, Linux on zSeries, Solaris SPARC, Solaris x86-64, Windows **************************************************************** PROBLEM DESCRIPTION: A race condition existed in the queue manager whereby if the queue manager was being ended very soon after being started (as happens during creation of a queue manager) the queue manager would wait for a thread to shutdown, but because the queue manager was ending the thread would not start. This caused ending of the queue manager to hang and an FDC to be generated. The queue manager would have to be killed.
Problem conclusion
IBM MQ has been modified to allow ending of a queue manager to occur even when it has not yet been fully initialized. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.5 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 ---------------------------------------------------------------
