    Mahesh Pogra Newbie

      Hi


      i have installed jboss-4.0.3SP1 and trying to understand the clustring.

      i have done nacessary setups in cluster-services.xml(MOST OF THEM ARE DEFAULT). i have used mcast option to detect other nodes in cluster. currently i have only my machine in cluster.
      i have used command line option -g to set the partion name and it's working but i m seeing below warings in server.log file

      Here all other senders do not belongs to my partition but why i m seeing that localhost means my server is also sending data to join the partition using "DefaultPartition", however my partition name is other then default partition name.

      Is there any other setting that i have to do?
      Please advise.

            Looks like the machine you are running jboss server on is a part of a network and other machines on the same network have it installed. This would generally not cause any issue if they were using different partitions. By default when you start jboss, it starts in default partition, and all other server instances running on the network that have not specified their partition name would join that default partition.

            Due to this, the messages are relayed to every server in the partition. To avoid this, you might need to specify the partition name and mcast address for the machine.

            Hope that helps.
