What are the parameters that define the communication between two nodes to be clustered on two different machines?
I have to create two nodes in a cluster. The two nodes has to reside on different machine.
In node1 (machine1) if have specified PartitionName and udpGroup as 188.8.131.52 (as stated in JClustering tutorial)
In node2 (machine2), I have done same changes.
But the org.jboss.ha.framework.server.ClusterPartition MBean does not show node2 as part of node1 cluster.
Do i need to ask my unix admin to open some ports on both the machine so that both machines can communicate? Or do i need to provide some values somewhere?
Please also note that if I cluster nodes on same machine (different package) it works fine, but if I move to different machine, clustering does not work.
