IT19539: GROUPED MESSAGES TRANSMITTED OVER AN MQ CHANNEL WITH THE CONVERTOPTION ARE NOT CONVERTED CORRECTLY

APAR status

• Closed as program error.

Error description

• When using the CONVERT option on MQ channels, individual
  messages are converted correctly. However incase of grouped
  messages the payload part of the grouped message was getting
  converted but the CCSID and encoding wasn't updated to receiving
  sides queue manager CCSID and encoding
  
  Eg: Message has CCSID 819, the sender is windows QMGR with CCSID
  437
  and receiver is QMGR with CCSID 437 with convert yes option on
  sender channel
  
  Before Conversion :-
  ---------------------
  
   StrucId 				'MD  '
   MQEncoding 		 0x'222'
   CCSID					 437
   Format 				'MQHMDE  '
  ......................................................
   StrucId				'MDE '
   MQEncoding		0x'111'
   CCSID					819
   Format				'MQSTR   '
  
  After Conversion :-
  ---------------------
   StrucId 				'MD  '
   MQEncoding 		 0x'222'
   CCSID					 437
   Format 				'MQHMDE  '
  ......................................................
   StrucId				'MDE '
   MQEncoding		0x'111'
   CCSID					819		----------------
  Still the MQEncoding and  CCSID isn't changed
   Format				'MQSTR   '
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Those using data conversion on grouped messages
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  Due to a programming error in MQ the MQEncoding and CCSID was
  not updated correctly when the message being converted contained
  an MQMDE header.
  

Problem conclusion

• Queue manager data conversion code has been modified to handle
  grouped messages with MDE header.
