PM43734: IQC6101I MESSAGE RECEIVED, WARNING THAT THE SHORT MESSAGE QUEUE IS ALMOST FULL WHEN IT IS NOT - PART 1

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• IQC6101I QUEUE SPACE USAGE WARNING. QUEUE DATA SET SMSQ USAGE
  COUNT IS 674 WHICH IS 95% AS SPECIFIED IN OVERFLOW TABLE.
  
  MSGIQC6101I is received incorrectly due to the customer system
  being XRF capable and the way QCF handles the two queue types
  (Normal and Local) after a restart.
  
  Originally LOCAL queues are used (before a restart), but after
  a restart the NORMAL queues are used which causes QCF to believe
  it's init was done thus incorrectly comparing the message
  belonging to the NORMAL queue with that of the LOCAL queue.
  
  Install the PTF for APAR PM48350 to get the full fix for this.

  * PROBLEM DESCRIPTION: IQC6101I message received, warning that *
  *                      the SHORT MESSAGE QUEUE                 *
  *                      is almost full when it is not.          *

  *                      table passes the queue numbers          *
  *                      for the LOCAL QUEUES - these numbers    *
  *                      are smaller then the numbers for NORMAL *
  *                      QUEUES, but they are not replaced on    *
  *                      next calls - and the protection uses    *
  *                      these to issue warning messages.        *

  * RECOMMENDATION:                                              *
  ****************************************************************
  The LOCAL QUEUEs are used during restart for master terminal
  traffic.
   QCF gets the information of QNSMDCB2 first and saves it into
  internal tables. After restart, the NORMAL QUEUEs start to be
  in use.
   QCF assumes its init was done, so incorrectly compares the
  numbers of messages, belonging to NORMAL QUEUE with the LOCAL
  QUEUE numbers, saved in the internal table.
   Programs are changed to compare the numbers on each call
  and replace them with the new values, if different.
  

Problem conclusion

• Install the APAR and restart the control region.
