Setting up a clustered Glassfish is quite easy.
For testing purposes I have created 1 one administration server, and 3 nodes. I am using the following for DNS resolution.
10.1.1.1 G2-ADMIN 10.1.1.2 G2-NODE1 10.1.1.3 G2-NODE2 10.1.1.4 G2-NODE3
This step is very important! When I was working on this article I had some problems getting it to work properly because I didn't have name resolution setup properly. If you do not have everything setup properly you will experience interesting problems that are quite hard to track.
The following steps need to be taken on the administration node.
The following steps need to be taken on the each of the cluster nodes.
Note: nodeX means node1 for G2-NODE1, node2 for G2-NODE2 and node3 for G2-NODE3.
You now have your cluster up and running. The next step is adding instances to your cluster. Go to the administration console of your administration host and create them there. Let me know what you think!
