APAR status

  • Closed as program error.

Error description

  • A second MQCONN call for the same client application fails to
    initialize the channel exit.  The xcsLoadFunction returns with
    xecU_I_FUNCTION_NOT_FOUND.  The following is found within the
    xcsLoadFunction call:
    
    FullPathLibName(ExitName) RC(24948)
    WindowsErrorNumber(126)
    WindowsErrorString(The specified module could not be found.)
    
    An AMQ9535 ( rrcE_USER_EXIT_INVALID ) is generated meaning that
    the "user exit is invalid".  The channel name and the name of
    the channel exit will be revealed by the AMQ9535 message text.
    
    The rriInitExits call ultimately ends with reason code
    rrcE_USER_EXIT_INVALID ( AMQ9535 ).
    
    The first MQCONN call is able to load the same configured exit
    for the same channel.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users running client applications that connect on channels for
    which exits have been defined.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    Incorrect logic concerning caching of connection data between
    connections caused the path to be used to channel exits to be
    corrupted.
    

Problem conclusion

  • The path caching logic was corrected.
