    Probe Id :- XC130031
    Component :- xehExceptionHandler
    Major Errorcode :- xecF_E_UNEXPECTED_SYSTEM_RC

    int,out int)
    UnmanagedNmqiMQ.MQCONNX(String,ref MQCNO,Hconn,Phconn,out
    int,out int)
    UnmanagedHconn.UpdateHconn(UnmanagedNmqiMQ,Phconn)
    UnmanagedNmqiMQ.MQOPEN(Hconn,MQObjectDescriptor,int,Phobj,out

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ v7 unmanaged .Net Client applications
    which use MQOD version less than 2 to access queues.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    When an unmanaged .Net application tries to open a queue with
    MQOD version set to 1, internally, an attempt is made to access
    a field that is not a part of version 1 MQOD resulting in an
    access violation.
    

Problem conclusion

  • A condition check was added to ensure that the queue manager
    does not try to access fields corresponding to MQOD version 2
    when the client uses MQOD version 1.
