4.2.4.2: Obtaining and using database connections

IBM WebSphere Application Server Version 3.5 provides two options for accessing database connections:

  • Connection pooling (model based on JDBC 2.0)
  • Connection manager (now deprecated, model based on JDBC 1.0)

Because connection pooling is the most efficient model for Web applications, it is recommended that you use connection pooling for all new applications requiring database access. You should consider migrating existing applications to connection pooling if your applications use connection manager or the standard JDBC 1.0 methods for getting database connections.

IBM WebSphere Application Server also provides data access beans, which offer a rich set of features for working with relational database queries and result sets.

For a comprehensive treatment of WebSphere connection pooling and data access, be sure to read the IBM whitepaper to be published on the Web during the summer of 2001.
