Hi All, Please read carefully and suggest me solution. I am working with one MNC s/w company.My application is web-based client-server application in which client and server are on different machines and uses same database. One imp thing one client might connect to more than one servers.Each server has one database which may be on server itself or on third machine. These servers stores some data in database. and also send a xml copy of same data on some port to client.web Clint get this data from server in the form of xml parses this xml and creates objects from that and stores in memory. If there are any changes in data server notify client so client can update its in-memory store.[client is not using database directly (jdbc)because firing query on Database every time is not feasible with current DB schema]But disadvantage of this is, if clients connect to multiple server [yes, there may be more than one servers]then performance of web-server on client decrease because it store data of all server in memory. Now we redesign the database schema and now client can connect to each server's database directly using OJB PersistanceBroker API and get data. IN Object cache implementation if there is some data in cache and same data get changed by server how clients knows this change and cache can be updated? This is my problem Thanks & Regards Amol Pophale.
