    delivery mode

    gschmidt Newbie

      Hi.

      i have got a problem solving the following szenario.

      1. I have two MQs with delivery mode "exactly once"
      2. I have multiple listeners requesting messages for processing from MQ A
      3. Listeners do long running tasks with these messages (eg. 5 secs)
      4. after processing a message it will be delivered to MQ B

      These thinks works perfectly well without transactions.

      BUT.

      I must go shure that each messages are processed correctly. so i added transactions to this scenario. then it is possible that multiple listener resolve a given message. --> delivery mode "exactly once" is violated.

      can anybody help?

      Thanks.

      Georg
