APAR status

  • Closed as program error.

Error description

  • When using a server side channel security exit with no
    corresponding client side exit, the exit causes the channel to
    close unexpectedly. The client throws an MQRC2009
    (MQRC_CONNECTION_BROKEN) and if multiplexing is in use, any
    other applications using the channel also lose their connection.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WebSphere MQ (WMQ) classes for
    Java Message Service (JMS) and the WMQ classes for Java that
    have a security exit defined on the queue manager side of a
    channel which returns an exit response of
    MQXCC_SEND_AND_REQUEST_SEC_MSG and no security exit
    defined on the client side of the channel.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    The client was sending a user ID (UID) flow
    rather than a security flow in response to the security exit's
    request.
    

Problem conclusion

  • The client now correctly responds to
    MQXCC_SEND_AND_REQUEST_SEC_MSG with a null security flow, rather
    than a UID flow.
