The connection pool clustering functionality optimizes the operations in a system where the database is used in a cluster configuration. You can use this functionality when you connect to Oracle using Oracle RAC. By using the connection pool clustering functionality, you can prevent the drop in system availability during errors and during maintenance. The following points describe the operations when an error occurs in the database node and when maintenance is performed for the database node while you are using the connection pool clustering functionality.

This section describes how to connect to Oracle clustered by using the Oracle RAC functionality, and the features and functionality of a connection pool when the connection pool is clustered (connection pool clustering).
