1st Attempt

[thorntond]

Hi All,

I currently have a web application running on JBoss 3.0 final release/Jetty/MySQL. Everything is currently running on 1 server. I would like to cluster the web application using 2 servers for failover purposes. This will be my first attempt at clustering a web application. Is there a documentation that explains how to handle ip routing, session state, EJBs, and database connections when clustering? From what I've read, it looks like the JBoss clustering documentation currently available only covers EJBs. Any help will be appreciated.

There is an article on O'Reilly OnJava written by Bill Burke and Sacha Labourey that is a very good introduction into clustering with JBoss 3.0.

Being new to clustering though, what I don't understand is how database connections are handled. Are all clustered JBoss application servers supposed to talk to one database/database cluster? If you are using a database that doesn't support database clustering, can you have a failover scenario using multiple databases with replication? I don't see how multiple databases using replication will work with clustered JBoss application servers but I thought I would ask anyway.
