If you want to use a DataSource that connects your applications to a database other than the system database of the SAP NetWeaver Application Server Java, you need to deploy the relevant JDBC driver for that database.
In the Telnet Administrator console:
Open the Telnet Administrator and login to the server. For more information, see Deploying a Standalone DataSource in Deploying DataSources.
Enter add dbpool in the command line to add the DBPOOL shell command group to the environment.
Enter deploy_jdbc_driver <driver-name> <driver_archive> in the command line, where:
<driver-name> is the name, under which this driver is registered in the system. You use this name as a value of the <driver-name> tag of the data-sources.xml file when you define your custom DataSource.
<driver-archive> is the directory path to the archive file on the file system that contains the classes of your JDBC driver. Note that this command can have multiple <archive-name> arguments separated with semicolons (;). This is necessary when deploying drivers that consist of several JAR files.
