IC89433: NEW FUNCTION TO PROVIDE A SAX PARSER IMPLEMENTATION OF INTERNAL XML PARSING FOR IMPROVED PERFORMANCE

APAR status

  • Closed as program error.

Error description

  • During normal processing, a large number of XML messages are
    received by a WebSphere MQ File Transfer Edition agent. These
    messages can either represent internal communications between
    agents, for example a transfer negotiation, or can represent a
    request from a user, for example a request for a new transfer.
    
    All such XML messages are parsed using a DOM model. Due to the
    nature of the messages there would be a performance benefit to
    using a SAX implemenation to handle these XML messages instead.
    

Local fix

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of WebSphere MQ File Transfer Edition 7.0.4
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ File Transfer Edition Agent consumes messages
    from its command queue during normal operation for a variety
    of reasons. These messages are in XML format, and are decoded
    with a parser using the DOM implementation.
    
    It could be more efficient to parse these messages with a SAX
    implementation.
    

Problem conclusion

  • If the new function for the 7.0.4.3 release is enabled, the
    agent will use a SAX implementation to parse its command
    messages, which should yield a performance benefit.
