# Configure a JDBC Connection Pool --> Choose database

Tasks Related Topics

## Overview

The JDBC Connection Pool Assistant is designed to help you configure a pool of connections from your database. It lists many drivers for many database types and prompts you for connection properties for the JDBC driver you select.

The Configure a JDBC Connection Pool Assistant --> Choose Database page includes the following options:

Database type—Select the DBMS of the database that you want to connect to. If your DBMS is not listed, select `Other`.

Database driver—Select the JDBC driver you want to use to connect to the database. The list includes common JDBC drivers for the selected database type. The driver you select will affect choices that you see in the next step in the JDBC Connection Pool Assistant. Select an XA driver if you want connections from the connection pool to participate in distributed transactions.

Notes: JDBC drivers listed in the JDBC Connection Pool Assistant are not necessarily certified for use with WebLogic Server. In keeping with the goal of the JDBC Connection Pool Assistant, JDBC drivers are listed as a convenience to help you create a connection to many of the database management systems available.

You must install JDBC drivers in order to use them to create database connections in a connection pool. Drivers are listed in the JDBC Connection Pool Assistant with known required configuration options to help you configure a connection pool. The JDBC drivers in the list are not necessarily installed. Driver installation can include setting system Path, Classpath, and other environment variables.

When a JDBC driver is updated, configuration requirements may change. The JDBC Connection Pool Assistant uses known configuration requirements at the time the WebLogic Server software was released. If configuration options for your JDBC driver have changed, you may need to manually override the configuration options displayed in Test Database Connection step of the JDBC Connection Pool Assistant or in the property pages for the connection pool.
