Error description

  • A multi-threaded client application which uses the Automatic
    client reconnect feature or connects with MQCNO_RECONNECT_Q_MGR
    option occasionally receives MQRC=MQRC_RECONNECT_FAILED during
    reconnection to a multi-instance queue manager.
    
    A trace of the problem shows that after successful reconnect the
    connection is subsequently rejected.

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ with client applications employing the
    MQCNO_RECONNECT_Q_MGR option in a multi-instance queue manager
    environment.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows)
    ****************************************************************
    PROBLEM SUMMARY:
    During the re-connect processing the WebSphere client was not
    identifying the queue manager ID correctly. This caused a new
    connection to be rejected.
    

Problem conclusion

  • The WebSphere MQ client code has been changed to correctly
    identify the queue manager ID and accept the connection.
