Tore, We have a somewhat similar configuration. By configuring workers in your main Tomcat, you can redirect your "client1", "client2",... "clientN" contexts to other tomcat servers via AJP13.
The Tomcat documentation has some decent examples of how to configure this (at least in 3.2.4 which is what we are using). We started out with a worker for each client but this is not scalable as your # of clients grows. The first problem is that when you configure a new worker you need to restart your main Apache/Tomcat server to recognize the new worker -- this means that your entire system is down, at least momentarily. More importantly, if you are directing each context to a single instance of Tomcat (i.e. you have a separate instance of Tomcat for each customer) this quickly becomes an inefficient use of resources. We ended up having over 50 workers redirecting to an equal # of Tomcat instances spread across 10 machines; this was not at all scalable. We ended up redesigning our system and in the process converted it to a shared model in which an arbitrary number of customers share use of the same tomcat instances. Now we are only using 4 workers to redirect to 4 tomcat servers for 60 multi-user customers. -Matt --- Tore Halset <[EMAIL PROTECTED]> wrote: > Hello! > > We are using jboss+tomcat on some servers.
