PI67728: AFTER UPGRADING FROM MQ V7.1 TO V8.0 MESSAGES THAT USE THE CLIENT'S CUSTOM DATA CONVERSION USER EXIT FAIL WITH RC 2119

APAR status

• Closed as user error.

Error description

• The client is using a custom user exit for data conversion. The
  problem is occurring when trying to convert a message from
  CCSID 875 to CCSID 813. The messages not getting converted are
  in Russion or Greek.
  
  MQXCNVC is invoked for conversion. The data passed to be
  converted contains some non-invariant EBCDIC data (in this case
  a '/' (forward slash) character) and the MQGET specified
  MQGMO_SYNCPOINT_IF_PERSISTENT. In this situation CSQACS64
  interprets the MQGMO_SYNCPOINT_IF_PERSISTENT as internal
  options and since the data contains non-invariant data returns
  CSQA_NOT_INVARIENT and does not perform the conversion and
  MQXCNVC returns MQRC_NOT_CONVERTED.
  custom user exit 2119
  

Local fix

• As a circumvention the customer could change their custom data
  conversion exit to take a local copy of MQDXP_APPOPTIONS and
  remove the x0001000 bit (i.e. logical AND with xFFFEFFFF), and
  pass this updated local copy to MQXCNVC.
  

Problem summary

Problem conclusion

Temporary fix

Comments

• The APAR is being closed as a user error.
  
  Further analysis showed that the user-written data conversion
  exit was passing invalid options to MQXCNVC, which resulted in
  the message data not being converted.
