APAR status

  • Closed as program error.

Error description

  • If a client .NET application connects, in managed mode, and if
    sharing conversation is disabled (SHARECNV=0), a GET with
    WaitInterval greater than 300 seconds fails with error
    MQRC_CONNECTION_BROKEN (2009)
    
    The error may occur for WebSphere MQ Clients at V7.0.1, V7.1 and
    V7.5.
    

Local fix

  • There are several ways to prevent this error:
    
    - set SHARECNV to a value greater than 0
     or
    - use unmanaged mode to connect to the queue manager
     or
    - set a smaller value for WaitInterval than 300
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    Users of WebSphere MQ Managed .NET client applications issuing
    MQGET with wait interval greater than 300 seconds
    
    
    Platforms affected:
    Windows
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    MQ .Net code fails to handle the heartbeat flow sent from server
    after 300 secs thus causing MQRC_CONNECTION_BROKEN error to be
    reported.
    

Problem conclusion

  • MQ .Net code is modified to handle the heartbeat and other
    non-heartbeat flows from server when multiplexing is disabled
