We are making a Web Based J2EE App having a scheduler, which runs as a seperate application. It normally sleeps, wait every 10 minutes and invokes a database read intensive method , to be specific, examines all the defined rules. Once it finds the successful rules, it takes appropriate action by invoking a SessionBean method. Given a frequency of 10 minutes and lot of database read / computation, less of database update , how should the rule verification ( intensive read and calculation ) be done ? Should it be routed using a session bean for data consistency or bypassing the session bean to preserve server resources for web - client service.    More>>
