When you use DB Connector to connect to a database, you use the RAR file supported by the JDBC driver to be used. Use the server management commands to operate the RAR file. For details on how to operate the RAR file by using the server management commands, see the uCosminexus Application Server Application Setup Guide.

The following table describes the types of JDBC drivers and the corresponding RAR files.
