To improve performance this EAServer release includes customized JDBC drivers. You can use these wrapper drivers in connection caches that are used by CMP entity beans. The wrapper drivers offer better performance by allowing updates to be deferred to the end of each transaction and sent together as a command batch. Doing so improves performance by reducing network round trips between the database server and EAServer. The Sybase wrapper driver also supports automatic creation of semi-temporary stored procedures, which also improves performance. For more information, see “Using CMP JDBC wrapper drivers” in in Chapter 4, “EJB CMP Tuning,” in the EAServer Performance and Tuning Guide.
