Error description

  • Local Java bindings connection failed with a reason code of 2009

    (MQRC_ENVIRONMENT_ERROR).
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users with Java/JMS applications connecting via local bindings
    on the IBM i platform are potentially affected.
    
    
    Platforms affected:
    IBM iSeries
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    A Java/JMS application attempted to connect to a local queue
    manager using a bindings connection, the attempt failed with a
    reason code of 2009 (MQRC_CONNECTION_BROKEN) with insufficient
    information on the cause of this error.
    

Problem conclusion

  • The reason code of 2009 (MQRC_CONNECTION_BROKEN) was returned
    incorrectly, the correct reason code should have been 2012
    (MQRC_ENVIRONMENT_ERROR). The environment had not been
    configured correctly to ensure that the job could start multiple
    threads, for example setting QIBM_MULTI_THREADED=Y. The native
    codepath that handles this error path was corrected to return
    the correct reason code.
