Subject: Caching data in an stateful session EJB???
>We are designing a system based on J2EE and EJB which needs to service
thousands
>of client applications. Originally we thought that each client would
interact
>with one stateful session EJB in order to collect & cache data pulled from
>corporate databases. However, ass I've been reading more on EJBs, it
sounds
>like this may not be a very good approach in terms of scaling and
>performance. If we use stateless session beans, where can we cache the
>data retrieved from the database? We need the data for subsequent
>calls to a rules-based engine to have it process and return information
>which we then return to the client app. Then, as we collect information
>from the client app, we need to combine this with the data from the
>db to be able to make more requests to the rules-based engine. So we need
>to cache it somewhere, but where?
>
>The machines we're running this stuff on are HP K380 w/2 CPUs and
>2 GB memory. We expect to start with 1000 simultaneous clients scaling
>up to 6000 for the call center. Then we will have the web clients to
>worry about on top of that, which will likely be 1000's more. Each channel
>(web and call center) will have it's own HP K380 (2 cpus) running the
>WebLogic app server.
