Jboss-6.0 Clustering question RedHat SELinux

[pkondaka1]

Hello Folks,

I am trying to start Jboss-6.0 installation in RedHat SELinux environment. Here is some information.

I have 3 different physical boxes with following IP addresses. 10.0.1.101, 10.0.1.102, 10.0.1.103 and have Jboss-6.0.0 unzipped in /usr/jboss-6.0.0 directory.

created node1, node2, node3 in different servers by copying /server/all to /server/node1 etc.

10.0.1.101/usr/jboss-6.0.0/server/node1

10.0.1.102/usr/jboss-6.0.0/server/node2

10.0.1.103/usr/jboss-6.0.0/server/node3

I am trying to start jboss using clustering with following

./run.sh -c node1 -g <partitionName> -b 10.0.1.101 -Djboss.messaging.ServerPeerID=1

./run.sh -c node2 -g <partitionName> -b 10.0.1.102 -Djboss.messaging.ServerPeerID=2

./run.sh -c node3 -g <partitionName> -b 10.0.1.103 -Djboss.messaging.ServerPeerID=3

First question, How do i know all these 3 are in clustered? I didnot see any kind of message in console saying "all are in <partitionName>" something ....

Please help me how test or make sure all these servers are in cluster.

Thanks

If you start the first you should find

'Number of cluster members: 1'

in you boot.log file.

If you start additional a message should logged that the number of Members is 2,3,4 ...

IF you want to see more you might change the category 'org.jgroups' to INFO/DEBUG/TRACE.

Also you can follow the example in .../deploy/jboss-logging.xml and log the cluster messages into a cluster logfile.

As i mentioned in my post, i am starting jboss in cluster using 3 servers. I didnot see adding up members to 2, 3. always see "Number of cluster members:1" in three servers boot log.

this is how i am starting up.

./run.sh -c node1 -g <default> -u 224.0.3.61 -b X.X.X.61 -Djboss.messaging.ServerPeerID=1

./run.sh -c node1 -g <default> -u 224.0.3.61 -b X.X.X.62 -Djboss.messaging.ServerPeerID=2

./run.sh -c node1 -g <default> -u 224.0.3.61 -b X.X.X.63 -Djboss.messaging.ServerPeerID=3

DO i need to use same multicast IP address? Do i need to open up any ports, since it is behind the firewall?

Please help me.

Thanks

Yes, you need the same mcast address for the -u option.

The cluster is controlled by the JGroups framework.

I suppose you have problems with multicast, are your systems within the same sub-net?

You might check the multicast function with the JGroups itselve.

See http://http://community.jboss.org/wiki/TestingJBoss

Best is to check and see the function if you start two instances at the same system.

The third on the second should join in the test-cluster.

Did this work?
