Entity Bean A, B, C's: Enterprise Java Beans Commit Options and Caching
نویسندگان
چکیده
Entity Beans provide both data persistence and the possibility of caching objects and data in the middle-tier. The EJB 1.1 specification has three commit options which determine how EJBs are cached across transactions: Option C pools objects without identity; Option B caches objects with identity; Option A caches objects and data. This paper explores the impact on performance of these different commit options, pool and cache sizes on a realistic application using the Borland Application Server.
