Error description

  • When using security exits :
    1. If MQXCC_SUPPRESS_FUNCTION is returned during the MQXR_INIT
    stage of the server side security exit managed .NET returns
    2059 instead of 2537 (MQRC_CHANNEL_NOT_AVAILABLE) that a C
    client does.
    2. For every other stage of the security exit if
    MQXCC_SUPPRESS_FUNCTION is returned a C client would return a
    2538 (MQRC_HOST_NOT_AVAILABLE) where the managed .NET returned
    a 2009 in most cases, but I did note that if I returned
    MQXCC_SUPPRESS_FUNCTION during the MQXR_SEC_PARMS call when a
    MQCSP had not been sent by the Managed .NET client the Managed
    .NET client returned a 2195.
    
    Also when the .NET managed application uses a channel name which
    does not exist to connect to queue manager, .NET returns 2059
    instead
    of 2540(MQRC_UNKNOWN_CHANNEL_NAME) that a C client does.
