Re: question on heavy load website design using struts
You could look at this : http://c-jdbc.objectweb.org/ this intermediate JDBC driver allow you to cluster databases. Notice I never used it, use it at your own risk ;-) Nico. 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?

Re: question on heavy load website design using struts
Sure! Only a little bit patience,please.It may take me one or two weeks to go over the test.I used to meet a problem on container managed security using jboss cluster.That is,jboss'clusterring feature works fine except when I use declarative security model to protect my page,the authenticated principal will not get replicated across the members in the cluster.At this time,I want to find a work around to that too.

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

Yup! :-) Open source rant: Some people just do not care about profitably until they are laying people of, because their competitors are more profitable. It's like being on a project where people have a short deadline: -we do not have time to unit test -we do not have time to do it right and use O.O. OK, I understand. They all will eventually, just plot the curve until they are all open source: ( a bit overused, but I love this chart) http://news.netcraft.com/archives/web_server_survey.html Saving money is good. .V - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
