Thanks Vic. We allready used PostgreSQL on a "non strategic" project, but our customers aren't open-source addicts (until they need to reduce costs !)

Re: question on heavy load website design using struts
FYI, one site I worked on P&T (performance and tuning) we improved performance by removing replication. Also look at postgresql.org, it is much like Oracle.

Sure!

question on heavy load website design using struts
Hi, I am sure that someone here must have worked on a large website with heavy load using struts and I wonder if you'll be kindly enough to give me some suggestions in this occasion. I am using tomcat+jboss as application server.I have setup several tomcat_jboss instances in a cluster environment and of course I use struts in my application.HttpSession created in one instance will get replicated across all members in the cluster.It's just what I want.The problem is how should I connect the app servers with the backend db server(s)? If I use only one db instance,all app server can connect to it without any problem,but here lies the bottleneck.I want to use several db instances(preferrably mysql).How can I do that?
