WebSphere MQ V7.0 Fix Pack 7.0.1.11
Fix Pack 7.1.0.4 for WebSphere MQ V7.1
WebSphere MQ V7.5 Fix Pack 7.5.0.3

APAR status

• Closed as program error.

Error description

• UserIdentifier gets converted to upper case when receiver
  channel message exit is installed in WMQ. This behavior is as
  designed, but this APAR provides an environment variable that
  an be set to override default behavior.
  

Local fix

• Remove the receiver channel exit.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users with message exits defined only on RCVR channels
  
  Platforms affected:
  All Distributed (iSeries, all Unix and Windows)
  ****************************************************************
  PROBLEM SUMMARY:
  Documented behaviour of not transposing the UID in the MD to
  lower case can cause issues for some customers.
  

Problem conclusion

• Check for an environment variable to allow the default behaviour
  to be overridden.
  Set the environment variable AMQ_MSGEXIT_UID_CASE to any value
  in the environment from which the listener is started. This may
  be the environment of the qmgr or of the listener.
