A sample DSN named DEVART_ORACLE is created during the driver installation. You can configure and adjust the DSN parameters as needed.
1. Open the odbc.ini file in a text editor, for example, nano.
Use the following command to edit the system-wide DSN.
sudo nano /Library/ODBC/odbc.ini
Use the following command to edit the user-specific DSN.
sudo vi ~/.odbc.ini
2. Add the configuration for your DSN in the odbc.ini file.
[DEVART_ORACLE]
Driver=Devart ODBC Driver for Oracle
Direct=True
Host=your_oracle_server_name
Port=your_oracle_listener_port
Service Name=your_oracle_database_name
User ID=your_oracle_user_id
Password=your_oracle_password

3. Save and close the file:
3.1. Press CTRL + O to save the file.
3.2. Press CTRL + X to exit the editor.
4. Optional: Test the DSN configuration with isql, a command-line tool for executing SQL interactively or in batches.
isql -v DEVART_ORACLE
Once connected, you can run SQL queries to retrieve data from Oracle.
Note
If the password isn’t saved in the DSN, you’ll be prompted to enter it at runtime when connecting to a data source. If the password is saved in the DSN, leave the Login and Password fields empty.
