Configuration for JBoss Clustering

[monasehgal]

I have 2 jboss servers running at two windows m/c .I would appereciate if any body can guide me with configuring Jboss clustering.Right now my application is in /default. Any reference to any documentation would be helpful

[darranl]

The JBoss documentation needs to be bought, there should be a link to the right of the page.

JBoss does come ready to run clustered without any changes.

If you install JBoss on two machines and on both machines start JBoss with run -c all instead of just run they will start with the all configuration which if there are no problems should result in you having two nodes in a single cluster.

There is too much really to go into on here, the documentation covers trouble shooting, settings for Windows and details on how to configure and use your application in a clustered environment.

[buckman1]

Make sure in your cluster-config.xml that you have the loopback="true" option set if you are running on Windows.

If you take the same 3.2.2RC1 version of Jboss, on two windows machines and do what darran1 said, after you see in each console window the ... Started.. at the end, scroll up somwhere near the middle you'll see something like:

****************************************
GMS: address is xxx:2820
*****************************************
[ClusterPartition] Starting channel..

and so forth. Look at BOTH of them at this location. See if one says Number of cluster memebers: 2, and one would say 1 (presumably the first one you started).

As long as you have not put in ANY beans or anything, and just ran it right out of the unzipped dir with the -c all config, you should have no problems. If you do, you either don't have loopback="true" for windows, or possibly multi-cast is not working. Run the JavaGroups test on both machines to confirm multi-cast works. IF that works, then you should have no other problem, as long as the computers are in the same subnet and network range.

[slaboure]

the version you are using (3.0.0) is more than 15 months old!!! Upgrade to 3.2.2Rc2 or 3.0.8.

Cheers,

sacha

[buckman1]

It helps to post versions of things. Had I seen the 3.0.0 in your post, I would have told you to make sure to go to 3.2.2RC1/2 or at least 3.2.1. Even so I mention in my post using 3.2.2RC. Make sure you look out for these types of things, it will help you avoid problems.
