    Migrating from 4.2.GA to 4.2.1.GA on a cluster

    Bernd Koecke Novice

      Hello all,

      I have a question about handling the message-table when running JBossESB on a JBossAS cluster.

      We implemented one of our business processes with JBossESB and jBPM on a JBossAS-Cluster and we want to bring more processes on this platform. We used the following versions:

      JBossAS: 4.2.2
      JBossESB: 4.2.GA
      jBPM: 3.2.2
      JBossMessaging: 1.4.0.SP1

      Now I try to update to JBossESB 4.2.1.GA. I had to change/add some things for version 4.2.GA. One addition is a special event-processor for category/name JBossESB-Internal/RedeliverService in file jbossesb.esb/META-INF/jboss-esb.xml. My processor emits events only on the clustermaster. Without this code all nodes will select on the shared table 'message'. To avoid this racing condition, I use my processor. Now I see some work was done for running ESB on a cluster. Is there a solution out of the box for managing the message table?

      Thanks in advance,
      Bernd
