    3.2.4 cluster problem

    amdonov Newbie

      I had two solaris machines clustered with 3.2.3. Moved to 3.2.4 and started an all instance on each box. They don't see each other. I can start two instances on the same machine and they cluster fine. The boxes both only have a single network card (That seemed to be causing others problems). Any ideas?

          Just as a follow up. I started 3.2.4 on one machine and 3.2.3 on the other. They see each other but complain about a version mismatch. So I'm guessing 3.2.4 is receiving requests fine but not broadcasting correctly.

            If I run the org.jgroups.demos.Chat program from the jgroups.jar 2.2.4 that comes with JBoss 3.2.4 I get the same behavior. Clients on the same machine see each other, but remote clients are not visible. Same demo with jgroups.jar 2.2.0 from JBoss 3.2.3 works. Can I use the old jar or will that cause me other problems?

              So you're saying the *same* program with the *same* config (cluster-service.xml) worked under 3.2.3, but *not* under 3.2.4 ?
              Can you
              - post your JGroups configuration
              - enable tracing

              Let's do Draw first so we can determine whether it is a JGroups problem.

              Copy your attribute from cluster-service.xml into a file, e.g. test.xml, and start Draw like this:
              java -Dlog4j.configuration=file:c:\log4j.properties org.jgroups.demos.Draw -props c:\\test.xml

              c:\log4j.properties needs to have an entry for org.jgroups set to DEBUG.

                Bela,

                Thanks for the response.

                The cluster-service.xml I am using is the default for 3.2.3

                I saved it as test.xml as suggested.

                If I run the 2.2.4 Draw program with no properties the machines never see each other, but multiple copies on the same machine show up.
                I can't get clustering to work under 3.2.4 with the cluster-service.xml that comes with it or the one from 3.2.3.

                Thanks for any help you can provide.
                I'll happily give you any more information you might need.

                  Upgrading to JGroups 2.2.5 fixed this problem.

                    I think I'm having the same issue.... Oups.... I shouted after a sysadmin because I thought he misconfigured the network...
                    Anyway, I've another solution:
                    http://jroller.com/comments/julien.dubois?anchor=unicast_clustering_with_jboss

                    It's not as good as upgrading JavaGroups IMHO, but it solves the problem, so I thought it might interest people in this thread.

                    HTH.
