[HELP]: Statfull WebApp Within Cluster

[sjunejo]

Hi,

I have a web application which is NOT statless, I have deployed it within my jBoss cluster with Hardware Loadbalancer, The problem is that my loadbalancer is forwarding the request in round robin fashion (which is expected) but as you know my application is Statfull it gives an error as soon as the request goes to the other jBoss member where my session was not started from.

The solution for this is configure loadbalancer to use stick session i.e. to forward request from session to single jBoss application server untill jBoss member server dies and then use session replication to switch the session to other member and carry on. The problem is that I do not have control over LoadBalancer as its running on Windows Cloud (Azure) which expects application to be stateless.

Anyway, is there a way to configure my application or jBoss cluster to keep these sessions in centralise location and accessable by both or all the members of the cluster.

Thanks,

I don't know what version of JBossAS you use, but if you use 6, you could use distribution (Infinispan: DIST) and requests landing on an incorrect node would get forwarded to the right node, which has the data.

You could also use synchronous replication (Infinispan: REPL_SYNC), which blocks the caller until the modification has been shipped across the entire cluster. Then, if the next request hits a different node, it will still get the correct data (e.g. a read).

Cheers,

Thanks Bela,

I am using jBoss 4.2.3 and jBoss 5.1.0. What about this http://docs.jboss.org/jbossas/docs/Clustering_Guide/beta422/html/clustering-http-app.html

Is it going to help? Also, is there any configuration guide to achieve this.

Let me know if you need more information.

Thanks
