Error description

  • After applying WebSphere MQ 7.0.1.1 on Windows, .NET client
    applications that rely on MQSERVER to connect to a queue manager
    start to fail with reason code 2277 MQRC_CD_ERROR.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of .NET using client connections from 7.0.1.1 and
    higher.
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM SUMMARY:
    A .NET application connecting with client bindings fails to
    take into account MQSERVER or MQCHLLIB/MQCHLTAB environment
    variables. For example, constructing a MQQueueManager object
    with a queue manager name will fail to connect via client
    bindings with a MQRC_CD_ERROR return code.
    
    This occurs because a change went into the .NET layer to
    distinguish between client and server connections, which forced
    a client connection to construct its own MQCD before the call
    and hence it skips the MQSERVER, MQCHLLIB/MQCHLTAB checking.
    

Problem conclusion

  • The .NET layer has been modified to correctly allow the use of
    MQSERVER and MQCHLLIB/MQCHLTAB environment variables when basic
    connections are attempted (in other words, when no connection
    name or channel is identified by the application).
