Subscribe

You can track all active APARs for this component.

 

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.
