On the Data Sources tab in the Data Sources and Drivers dialog, click the Add icon () and select Oracle.
At the bottom of the data source settings area, click the Download missing driver files link. As you click this link, IntelliJ IDEA downloads drivers that are required to interact with a database. The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version.
You can specify your drivers for the data source if you do not want to download the provided drivers. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.
From the Connection type list, select a connection type:
SID: to use a unique name of an Oracle instance (a process that runs on the workstation).
To use a correct value, check the environment variable
ORACLE_SIDon the server host, or contact your database administrator. Commonly-used values are
Service name: to use an alias to an Oracle instance (or many instances).
TNS: to use tnsnames.ora configuration file. In the TNSADMIN field, specify a path to the folder with tnsnames.ora. In the TNS name field, specify what service name to use (see a value of
net_service_namein tnsnames.ora) if you have more than one service.
For more information about tnsnames.ora, see Local Naming Parameters in the tnsnames.ora file.
URL only: to use the JDBC URL.
From the Driver list, specify the driver type. For more information about driver types, see Oracle JDBC FAQ.
Specify database connection details. Alternatively, paste the JDBC URL in the URL field.
