JBoss clustering

[hyao]

hi, all.

I am using JBoss3.0.2+Jetty. Is there anyone know how to clustering on JBoss? Here is what we want: 3 machines in a clustering, one is a web server(Jetty), and the others are 2 app servers(which are on 2 different machines) as EJB container only. In this way, the web server will handle all http requests and make remote calls to those 2 app server if necessary, and those 2 app servers will have Entity beans/Stateful session beans clustered.

Any idea about how to configure that?

Thanks,
hongmei

Hello,

Maybe you'd better use apache on the front-end box and serve only static content and, for active content, redirect to the two JBoss instances running in the background using Apache load-balancing (with sticky sessions, see earlier posts on this topic in the forum)

Then, on each of the JBoss instance (i.e. 2), you run Jetty/tomcat and the EJBs in-vm. You thus have a cluster of 2 nodes.

Cheers,

Hey Sacha,
What we are trying to do is load balance a data load operation. I believe Jack talked to you about this at the
NY Advanced training class. Here is a quick rehash:
3 machines each with a web server and app server.
1 request to load say 10,000 files.

The web/appserver that gets the initial request divides
the files into smaller chunks that are then handed off to
SLSB's to parse the files and update the DB. We would like to have a RoundRobin load balancing for the 2 boxes
that did not get the initial request.

I believe you told Jack that we might have to change some
code. If you could point to a package we should look at it would be a big help.

Thanks,
Andrew
