IC60253: MESSAGES SENT FROM WINDOWS WMQ V7 JAVA CLIENT TO Z/OS QMGR DEFAULT TO THE Z/OS CCSID OF 500 INSTEAD OF WINDOWS DEFAULT 819

WebSphere MQ V7.0 Fix Pack 7.0.1.1
WebSphere MQ V7.0 Fix Pack 7.0.1.2

APAR status

• Closed as program error.

Error description

• When using the WebSphere MQ v7 classes for Java to put messages
  to a z/OS queue manager and using the
  MQMessage.writeBytes(String) method, the CCSID of the messages
  in the client is 0, causing the CCSID to be set at the queue
  manager end to 500.
  

Local fix

• In the client app set the MQMessage.characterSet value prior to
  the PUT instead of allowing it to default to 0.
  For example: myMsg.characterSet = MQEnvironment.CCSID
  would set the MQMessage.characterSet to the platform default
  In this case Windows CCSID 819
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users putting messages remotely to a z/OS
  queue manager, but could also affect any system in which the
  queue manager has a different codepage to the client and where
  the message contains characters that are not part of the
  invariant ASCII codeset.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  The algorithm in the MQMessage.writeBytes(String) method was
  changed between V6 and V7. In V6, the CCSID would default to
  819, but this did not occur in the GA V7 code.
  

Problem conclusion

• The MQMessage.writeBytes(String) method was changed to
  incorporate the same default behaviour as the V6 client. This
  means that the default CCSID of the MQMessage class will be set
  to 819 in all cases.
