Error description

  • This new function for WebSphere MQ File Transfer Edition
    v7.0.4.3 introduces the ability to specify the priority of
    messages used internally by the agent during a transfer.
    
    Without this feature all messages created by commands or the
    agent will have the same priority. In situations where a very
    large number of new transfer requests are on an agent's command
    queue, internal conversation messages can experience significant
    delay before being processed. This delay can cause transfers to
    enter recovery thereby incurring further processing and delay on
    both the source and destination agents for those transfers.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ File Transfer Edition 7.0.4
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    During normal processing the WebSphere MQ File Transfer
    Edition Agent process messages from its command queue for
    several purposes. It uses this queue both to communicate with
    other agents for the processing and recovery of transfers, and
    to accept input from users, to create a new transfer or ping the
    agent for example.
    
    A very busy agent may appear to become unresponsive, as it
    will not be able to respond to an agent ping or new transfer
    request in a timely manner. Although the agent will eventually
    respond, it may appear to the user that it has hung.
    

Problem conclusion

  • The commandMessagePriority property has been introduced to set
    the priority of both internal messages and command messages
    for thefteStopAgent, fteCancelTransfer, ftePingAgent, and
    fteSetAgentTraceLevel commands. You can also use the
    commandMessagePriority property to set the priority of
    internal acknowledgement and acknowledgement-expected
    messages. You can set commandMessagePriority to a value to
    prioritize internal WebSphere MQ File Transfer Edition
    messages above new transfer requests, which can improve agent
    performance.
