Double Messages in broker JMS 7.1 - multiple processing

  • 1.  Double Messages in broker JMS 7.1 - multiple processing

    Posted Mon October 27, 2008 09:13 PM

    Hi,
    In the developement with webMethods 7.1 with JMS broker we have the following problem:
    In the publication in a JMS Topic : when there are multiple publications which are simultaneous or near we have the random phenomen : the JMS triggers makes multiple execution for the same publication
    We respect the rule Exactly-Once Processing for JMS Triggers (§6).
    When the publications are separated by time (> 30 seconds t 1 minute), we have not the problem.
    We applied the parameter Exactly once / Detect duplicates = true with concurrent mode and with maxThread=5 like a “classical” trigger
    We did a restart of the IS but the problem remains.
    Here are the IS parameters :

    • 7.1.1 (service pack 1)
      We did not have the JMS Fix1 ? Should it a reason for the problem ?
      Should we install the service pack 2 ?
      Thanks for help
      Regards,
      François Chapuzot

    I have the exact same problem.

    see post: [URL]wmusers.com.

    everything works fine with local broker triggers and the IS servers using the same client prefix in the broker setting page. but not for JMS
