Hello everybody

As a eclipselink newbie I wanted to ask you some questions about cache. I'm plannig an application with:
- 1 oracle 11 database
- 1 server
- many java SE clients.

To implement the solution I'm planning to use eclipselink. Because datasets on which clients will operate will be more less independent I'm not planning to cache the data on the server (it will perform more like a data connection pool). Data will be cached on clients. However it is possible, that one client will change data that is cached on other client (for example a dictionary entry), or an oracle job can update the database. I know I can configure DCN to udpate the cache on server (which is accessing the database). Will the server invalidate caches on clients as well? Will it send only notifications to clients which really cache the changed data or will it broadcast the notification to all connected clients?
Is architecture like this possible?

Thank you in advance for your comments!
