deploying applications in selected Multiple Nodes in JBOSS 4

[viswanadhvk]

Hi Friends, I am working on JBoss 4.2.1

My task is to deploy an application (ear file or war file) in clustered environment.The catch here is I need to deploy the application in selected multiple nodes.

for e.g. I have 3 Nodes Node1,Node2,Node3. and I would like to deploy the application in Node1,Node3 (and not Node2).Even though all the nodes are in cluster. In the sense ,If I start the server like,

for "all"
run -c all

for Node1
run -c Node1


for Node2
run -c Node2


for Node3
run -c Node3

If we see in the console of "all" we can see that all the server(Node1.Node2,Node3) are in cluster and shows as shown below

12:14:19,649 INFO [DefaultPartition] All Members : 3 ([127.0.0.1:1099, 127.0.0.1:1200, 127.0.0.1:1299])

Some body told me that If we deploy the application (ear or war) in "all\deploy " , "Node1\deploy" , "Node3\deploy" and not in Node2

(since I would like to deploy the application in Node1, Node3 only and not in Node2).

then it would be deployed and those two nodes only.

I did the same as I explained above,

(1) I want to know whether this method is correct
(2) If so , How to know the Nodes are having the same application and those nodes are in cluster (Node1,Node2).

Please any body can show some light on this.

If all the above information is not correct , can any body tell me ,

(3)can we deploy the application in selected multiple Nodes are not?
(4)If so please let me know how to do that?

Thanks!

Hi friends , at least pls try to respond some thing.

I think, you are right.
If you want to deploy only in node1 and 2.
Put the app in deploy directory of (node 1 and 2) only.

To see if they are in cluster, do fail-over testing...

Yes, this is correct.

To get information about what clustered services are deployed on what nodes, you can try looking in the jmx-console at mbean jboss:service=DistributedReplicantManager,partitionName=DefaultPartition

From there you can invoke on the listContent() or listXmlContent() operations. It's a bit of a black art to interpret that output, but each clustered EJB should show up there. Distributable webapps won't appear though, as they don't use that service.
