IC72897: ADD PROPERTIES TO ENABLE V7.0 WMQ JMS APPLICATIONS TO CONFIGURE MESSAGE DATA CONVERSION TO OCCUR IN THE QUEUE MANAGER OR CLIENT

WebSphere MQ V7.0 Fix Pack 7.0.1.5
WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.5

APAR status

• Closed as program error.

Error description

• The WebSphere MQ V7.0 classes for JMS (Java Message Service)
  applications request messages from the queue manager using the
  MQGET option:
  
  MQGMO_CONVERT
  
  This option requests that the queue manager performs message
  data conversion before sending the message to the JMS
  application.
  
  There is no mechanism which permits the client application to
  configure the use of this setting using the WebSphere MQ
  classes for JMS.
  
  The WebSphere MQ V6 classes for JMS do not use this option.
  This means that messages are retrieved from the queue in the
  form with which they were stored on the queue, and the
  WebSphere MQ classes for JMS are responsible for data
  conversion into a native form for use within the JVM and client
  application.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - the WebSphere MQ V7.0 classes for JMS.
  - the WebSphere Application Server V7 WebSphere MQ messaging
  provider.
  - the WebSphere Application Server V6 WebSphere MQ messaging
  provider who have configured the WebSphere Variable
  MQ_INSTALL_ROOT to point to a WebSphere MQ V7 installation.
  - the WebSphere MQ V7 Resource Adapter.
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows) +Java
  ****************************************************************
  PROBLEM SUMMARY:
  The MQGMO_CONVERT option was added to the MQGET request
  associated with the WebSphere MQ V7.0 classes for JMS's receive
  request:
  
  MQMessageConsumer.receive()
  
  as a way to enable WebSphere MQ conversion exits to be run when
  requesting messages with a JMS client.
  
  This change was intended to be transparent to existing JMS
  applications.  However several problems have been reported for
  applications which have been migrated from the WebSphere MQ V6
  classes for JMS to V7.0.

Problem conclusion

• Two new properties have been added to WebSphere MQ JMS
  Destination objects which permits configuration of both the
  MQGMO_CONVERT option when performing message receive requests,
  and the CCSID which the queue manager is requested to convert a
  message to when using message conversion.
  
  These properties are:
  
  RECEIVECONVERSION  Configures use of MQGMO_CONVERT.
  RECEIVECCSID       Requested CCSID to convert the message to
  when using MQGMO_CONVERT.
  
  Their use is described in detail in the technote:
