PI65143: GROUP MESSAGES ARE NOT HAVING THEIR DATA FOLLOWING THE RFH CONVERTED FROM CCSID 1208 TO 500.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• It occurs when there are two or more architected headers
  (in this case the MQHMDE and MQHRF2), both of which are
  already in the requested code-page (the MDE and RFH2
  headers are already in ccsid 500). The data-conversion
  code (CSQAVD64) assumes that there is no more data
  conversion to be performed, so any data following the
  RFH2 is not converted.
  
  For MQ V7, this problem only affects batch applications
  using MQGMO_CONVERT.  This includes RRS, which in turn includes
  WebSphere Application Server (WAS) bindings connections and IBM
  Integration Bus (IIB / Message Broker).
  The problem does not affect the Channel Initiator (CHIN), CICS,
  or IMS.
  For MQ V8, batch applications and the CHIN are affected--see
  PI65147.

  ****************************************************************
  After getting a message and detecting that conversion is
  required, CSQBSRV calls CSQAVD64 to perform the conversion.
  CSQAVD64 checks the CodedCharSetID and Encoding of the first
  two headers in the message. If these match it incorrectly
  assumes that the message is already in the requested Encoding
  and CodedCharSetID and skips further conversion, leaving any
  subsequent chained headers and message data in their original
  CodedCharSetID and Encoding.
  

Problem conclusion

• CSQAVD64 is changed to no longer skip conversion if the first
  two headers are already in requested CodedCharSetID and
  Encoding, so that the requested conversion will take place for
  any subsequent headers and message data.
