PM84015: CSQJ105E IS ISSUED REPEATEDLY AND LOG SWITCH DOES NOT OCCUR

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• CSQJW107 fails to update the end RBA of the active log dataset
  (LDSDWND6) if there is a failure writing to the first CI of
  the dataset. This means that CSQJW107 does not invoke
  CSQJW307 to perform log-switch, so CSQJ105E is repeatedly
  issued for the same active log dataset.
  

Local fix

• Cancel the queue manager if it is still running.
  Use CSQJU003 to remove the faulty active log dataset(s).
  Start the queue manager. It should resume normal processing.
  
  Use the normal procedures to add more active log datasets to
  replace the ones that were deleted.

  ****************************************************************
  If a failure occurs during the write to the first Control
  Interval (CI) in the current active log dataset by the queue
  manager, CSQJW701 should update the end RBA of the current log
  and switch to the next active log.
  However this does not happen, thus the queue manager keeps
  retrying the write to the same active log.
  

Problem conclusion

• The code was changed to correctly update the end RBA of the
  active log dataset and switch to the next active log.
