Hello Scott,

I successfully installed and tried out a few JBOSS features on a SSI
cluster. 

I tried both of the JBOSS configurations, Running several jboss
instances on a single node and also having one jboss instance run on
every node of a ssi cluster.

In both the configurations, every JBOSS instance needs a separate
installation directory, which will be its JBOSS_HOME (which is the
directory created by untaring the JBOSS distribution tar ball). Which
will include its own configs, its own deployment directories to serve,
its own log, and its own scratch directory. 

The difference in setting up JBOSS on a sea of nodes and on a SSI
cluster would be the ease of install. Because of the single filesystem 
its easier to lay your JBOSS_HOME's for all nodes by creating separate
"directories" under user jboss.

My configuration looked like,

/home/jboss/jboss1
		 /bin
		/client
		/deploy
		/lib
		/server

/home/jboss/jboss2/
		 /bin
		/client
		/deploy
		/lib
		/server

/home/jboss/jboss3/
		 /bin
		/client
		/deploy
		/lib
		/server
     .
     .
To start JBOSS instances on a single node, I had to make the respective
port changes ( as you indicated too). And to run them one instance on
every node, I had to simply start them on each node (no port changes
needed). 

About setting up a JBOSS cluster, I just ran the "all" jboss
configuration ( run.sh -c all). As the jboss instances started up they
became part of the JBOSS default cluster.

I used the jboss-tomcat version so that I could use it with
apache-mod_jk to do the loadbalancing of servlet and ejb requests
between the various JBOSS instances. I had apache running on the root
node of the cluster and one jboss instance running on each other node of
the ssi cluster.

Tried the Java Petstore application. I was able to loadbalance and also
failover between various JBOSS instances. I had enabled the http-session
replication feature in the application. But I could not exactly validate
if it was really happening. 

Thanks,
Roopa

This allows you to clean have different ip/port bindings and log files.  And when you do a deployment you will not have all your jboss instances doing the deployment at the same time.
