IT15208: MQ V8: FDC WITH PROBE ID ZX092012 GENERATED WHEN ENDING QUEUE MANAGER WITH -P FLAG

APAR status

• Closed as program error.

Error description

• When performing a pre-emptive shutdown of the queue manager
  (endmqm -p), a failure data capture (FDC) file may be generated
  by the amqzmur0 process with probe ID ZX092012.
  This behaviour may be observed on queue managers running on the
  MQ Appliance or on distributed platforms.
  The contents of the FDC file are similar to the following:

Local fix

• These FDCs will only be observed when starting and stopping the
  queue manager in quick succession, and can be ignored.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This is a very low impact problem and only affects customers
  that start and stop queue managers in very quick succession.
  
  
  
  
  Platforms affected:
  AIX, HP-UX Itanium, HP-UX PA-RISC, IBM iSeries, Linux on Power,
  Linux on S390, Linux on x86, Linux on x86-64, Linux on zSeries,
  Solaris SPARC, Solaris x86-64, Windows
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The FDC indicates that one of MQ's internal tasks received
  MQRC_Q_MGR_STOPPING during initialisation, but there was no
  provision in the internal logic of the task to handle this
  reason code at this point. The task ended as a result of this
  issue but it had no impact because the queue manager was ending
  anyway.
  

Problem conclusion

• The affected internal tasks within the MQ queue manager have
  been updated to correctly handle the MQRC_Q_MGR_STOPPING reason
  code.
