IT23169: Pub/sub MQGET returns warning with reason code 2111 MQRC_SOURCE_CCSID_ERROR

APAR status

• Closed as program error.

Error description

• The subscriber app called MQGET with MQGMO_CONVERT.
  
  The message contained headers with (header).CodedCharSetId =
  MQCCSI_INHERIT.
  
  The MQGET call incorrectly returned the unconverted message to
  the application with warning completion and reason codes
  (CompCode = MQCC_WARNING, Reason = MQRC_SOURCE_CCSID_ERROR).
  
  The correct behaviour is to convert the message.
  
  Also failure data capture (FDC) records might be written with
  details matching these:
  - VP028002 vwb_rf_header vrcE_BAD_CCSID_0
  - VP029002 vwb_rf_header_2 vrcE_BAD_CCSID_0
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Publish/subscribe applications where the message contains
  headers that use MQCCSI_INHERIT.  The problem does not affect
  point-to-point queued MQPUTs/MQGETs.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The published message contained at least one MQ header in which
  the (header).CodedCharSetId was MQCCSI_INHERIT.
  
  MQCCSI_INHERIT has the value -2, and is not a real coded char
  set identifier.  Instead it is an instruction to the queue
  manager that it should replace the (header).CodedCharSetId with
  the value from the preceding header.
  
  The MQ code was not successfully changing the value to the
  correct coded char set identifier (CCSID), but was leaving the
  value of -2 in that position.
  
  The subscriber called MQGET with MQGMO_CONVERT.  Because the MQ
  code had not changed the value from -2 to a real valid CCSID,
  the MQGET returned the unconverted message to the application
  with warning completion and reason codes (CompCode =
  MQCC_WARNING, Reason = MQRC_SOURCE_CCSID_ERROR).
  

Problem conclusion

• The MQ code has been corrected to ensure that the occurrences of
  MQCCSI_INHERIT are replaced with the correct CCSID, so avoiding
  the problem reported.
