The drivers for the IBM® databases, such as DB2® for Linux, UNIX, and Windows, DB2 for z/OS®, and Informix®, are preinstalled. If you want to create a connection by using one of the preinstalled drivers, go to the Manage Connections tab and create a connection.
If you want to use a Microsoft SQL Server or Oracle driver, you will need to configure the driver first. For each new driver, create a definition on the Manage Data Server Drivers page. Drivers are published by their vendors, therefore, you must specify the driver class when you create the driver definition. You can find the driver class information in the vendor documentation. After you define the driver, you can create a connection to refer to this driver on the Manage Connections tab. You can create, delete, and edit data server drivers on the Manage Data Server Drivers page.
