Cluster start-up parameters

[codevally]

Hi All

Currently I am using JBoss AS 5.1 and starting my cluster using

          run.sh -c node1 -b 0.0.0.0 -u 228.28.28.28 -g devPartition -Djboss.messaging.ServerPeerID=1

I just want know any implications happen if I pass -Djgroups.bind_addr=app.dev1.ourserver.net system property alone with the above parameters as below.

          run.sh -c node1 -b 0.0.0.0 -u 228.28.28.28 -g devPartition -Djgroups.bind_addr=app.dev1.ourserver.net -Djboss.messaging.ServerPeerID=1

Any help is appriciated.

The implications depend to your network configuration.

If you use the jgroups.bind_addr the multicast of 228.28.28.28 will be only received from that interface.

If your network configuration does not provide the mcast to this address your cluster is broken/isolated.
