Thanks Jeanne,

Its a position monitoring system for a stock lending application. The users are logged in all the time but the data which is around 10 seconds old is tolerated. That is the reason I was planning to write a thread and update the data in cache every 10 seconds. I am using Web logic in a clustered environment. How can I use caching mechanism in Web logic? Any thoughts...

Hi All,

I need to find a way to improve performance of my application. here is the scenario,

Its a J2ee application. The client will send the request to the servlet (programmatic) after every 10 seconds. The servlet will query the database and return the results. Currently there are few users but in future when the user base increases, this approach wont work as there will be many concurrent requests and hence load on the database and the application.

I was thinking of writing a thread which will ping the database after every 10 seconds and store the "Superset" of the data in an application wide object (e.g. a table structure in app context). The servlet will query this object instead of the database on each request.

Is it a right approach? Also in case of "Clustered Environment" will this work? My concern is whether app. context is replicated over clusters?

Can any one suggest me a better approach or tell me if I am missing something.

Any help is really appreciated

Thanks,
Sameer
