Db2 Jdbc Driver Connection Pool
The presence or absence of connection pooling shouldn't make any difference to the application code. Tips: JDBC 3.0 has additional features to improve performance such as advancements in connection pooling, statement pooling, RowSet objects. OC4J will automatically load the driver classes during server startup.

- According to the JDBC 2.0 API specification, a data source is registered under the JDBC subcontext or one of its child contexts.
- The JDBC context itself is registered under the root context.
- Tips: Make the servlets thread-safe and use connection pooling.

Nov 12 '05 #5 P: n/a John Thanks for the response(s), Its the last line that takes ages & I am running it outside of a J2EE container. wait-timeout Number of seconds to wait for a free connection if all connections are used.
Since I only need a single connection per process - I'l hold it open passing it forward for the next client user. As far as I know, any connection pooler that sits between applications and the CLI code should work. Thanks John Nov 12 '05 #3 P: n/a John Phil, The problem - I have 'working' JDBC code that makes use of data source and pooling, called as follows (its happens Likewise, as the number of user requests begins to grow, new connections are created.

However do not release the connection only to use it again almost immediately, instead hold the connection until it will not be immediately needed. In the Minimum connections box, type 1.

Prepared statement pooling (available from JDBC 3.0) caches SQL queries that have been previously optimized and run so that, should they be needed again, they do not have to go through If you have lot of code using data access beans that need to be migrated to OC4J, then put databeans.jar in the classpath of OC4J. source-location Underlying data source of this specialized data source.
In the Implementation type list, select Connection pool data source. What are the differences between Holmes D&D and Original D&D? The primary tip, repeated again and again, is to use connection pooling. OC4J will treat the cataloged database as a local database.
