IT40787: TRIGGER A QUEUE MANAGER FAILOVER IN CASE OF STOP_ALL CONDITION.

APAR status

• Closed as program error.

Error description

• MQ uses an internal error condition to handle fatal errors.
  This error condition is known as STOP_ALL.
  If this error condition occurs, the queue manager stops.
  
  The problem can be identified if the STOP_ALL error condition
  shows up in an FFST file:
  | Major Errorcode   :- STOP_ALL
  | Minor Errorcode   :- OK
  | Probe Type        :- HALT6110
  | Probe Severity    :- 1
  | Probe Description :- AMQ6110: An internal IBM MQ error has
  occurred.
  
  The queue manager creates an error message in the AMQERR* log
  file:
  
  ACTION:
  IBM MQ will stop all MQ processes.  Inform your systems
  administrator. When the problem is rectified IBM MQ can be
  restarted.
  

Local fix

• In this case the queue manager needs to be restarted using
  strmqm.
  

Problem summary

• The handling of the STOP_ALL error condition leads to a self
  initiated queue manager stop.
  

Problem conclusion

• The queue manager has been improved and initiates a takeover
  instead of a stop.
  The takeover procedure stops the Execution Controller primary
  process.
  The Execution Controller backup process takes over, becomse the
  new primary and starts another backup.
