Error description

  • When using a combination of WebSphere MQ Managed File Transfer
    (MFT) agents at version 7.5.0.0, 7.5.0.1 and 7.5.0.2 in the same
    topology as WebSphere MQ File Transfer Edition agents at version
    7.0.4.3, file transfers between these agents fail. In this
    scenario, there are two outcomes:
    
    Outcome 1:
    
    The transfer freezes in "starting" state and is unable to be
    recovered. The WebSphere MQ MFT v7.5.0.x agent generates a
    FFDC with the following error:

    The WebSphere MQ MFT v7.5.0.x agent generates an FFDC (as above)
    and also ABENDs with the following ABEND file generated:

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects all users of WebSphere MQ Managed File
    Transfer who also have WebSphere MQ File Transfer Edition
    v7.0.4.3 agents in the same topology.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    WebSphere MQ Managed File Transfer (MFT) and File Transfer
    Edition (FTE) agents report their version number when sending
    messages between agents that coordinate file transfers. A
    WebSphere MQ Managed File Transfer agent was unable to correctly
    interpret the version number reported by a WebSphere MQ FTE
    v7.0.4.3 agent when it received response messages from this
    agent.
    
    In the scenario where a file transfer is requested from a
    WebSphere MQ MFT source agent to a WebSphere MQ FTE v7.0.4.3
    destination agent, the response message sent by the v7.0.4.3
    agent once it is ready to receive data from the v7.5.0.x
    source agent causes this source agent to generate an FFDC as
    it cannot correctly parse this response message.
    
    In the scenario where a file transfer is requested from a
    WebSphere MQ FTE v7.0.4.3 source agent to a WebSphere MQ MFT
    destination agent, when the v7.5.0.x destination agent
    performs transfer checkpoint processing, the inability to
    correctly interpret the version number reported by the
    v7.0.4.3 source agent causes the WebSphere MQ MFT destination
    agent to ABEND.
    

Problem conclusion

  • The WebSphere MQ MFT agent has been updated so it can
    correctly interpret the version number reported by a WebSphere
    MQ FTE v7.0.4.3 agent.
