Connect to Oracle in Tableau

Open Tableau and click More under Connect -> To a Server. Select "Oracle by CData," then configure the connection and click "Sign In."

To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:

  • Port: The port used to connect to the server hosting the Oracle database.
  • User: The user Id provided for authentication with the Oracle database.
  • Password: The password provided for authentication with the Oracle database.
  • Service Name: The service name of the Oracle database.

  2. Select OracleOCI from the Schema pull-down menu.
  3. Drag the tables and views you wish to visualize onto the join area. You can include multiple tables.
