PH62867: APPLICATION PCF REQUEST RESET QSTATS FAILS WITH COMPLETION CODE 2, REASON 3014

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Development analysis found that the reason that the PCF message
  validation was failing was because the 0x0000044F
  (MQIACF_Q_STATUS_TYPE) in the PCF message had been changed to
  0x0000045A (MQIACF_AUTH_PROFILE_ATTRS) which is invalid for a
  DISPLAY QSTATUS command. GTF trace showed that this value had
  changed between the group command server in CSQNGRS1 copying
  the PCF message from the DXWB in CSQ5RCMQ to calling CSQ9SCN0
  to parse the PCF message.
  
  
  
  Close inspection of the code between these two points revealed
  the problem. If the CCSID in the inbound DXWB is different to
  the QMGR CCSID, then the QMGR will attempt to convert the
  message. This logic doesn't account for converting PCF messages
  and instead uses a string conversion function. In this APAR's
  case, one MQ instance used CCSID 500 while the other used CCSID
  1140. Although both are EBCDIC CCSIDs, converting between these
  two CCSIDs results in an 0x4F character getting translated to
  an 0x5A character. There are also other code point differences
  which could affect other PCF messages.
  

Local fix

• Work around this problem by ensuring that each QMGR in a QSG
  has the same CCSID.

  *                      messages in a queue sharing group with  *

  *                      in PCF response messages.               *
  ****************************************************************
  The code which handles data conversion of commands on the system
  command input queue doesn't check for PCF messages, resulting in
  incorrect data conversion.
  

Problem conclusion

• The code has been changed to check for PCF messages when
  processing messages on the system command input queue.
