Tune the data source pool size and database type

Tune the cache size parameters as described in “Data source settings”. For EJB CMP entity beans, make sure you specify a Database Type that matches your database server. The database type definition allows the persistence engine to make use of database-specific features such as stored procedures and statement batches. You can create additional database type definitions as described in “Configuring database types” in Chapter 4, “Database Access,” in the System Administration Guide.
