Oracle

This procedure explains how to configure an Oracle database connection, including both database types (Oracle and Oracle for 9.X, 10.X, 11.1). It is assumed that you are working on the General tab of the New Oracle connection dialog and need to provide connection details relevant for this particular database type.

Configure an Oracle database connection

  1. Open the New Oracle connection dialog. Select the tab for one of the two options:

    • From the editor, to attach the new database to a specific notebook

    • From the Home page, to add a database connection to a workspace

    • Go to Main menu | Tools | Attached data or click the Attached data icon on the left-hand sidebar.

    • Click New connection and select New database connection.

    • In the New database connection dialog, select Oracle.

    • On the Home page, select the workspace where you want to create the connection.

      Selecting a workspace
    • Select Databases from the menu under the workspace name.

    • Click the Add connection button in the upper right corner. The New database connection dialog will open.

    • In the New database connection dialog, select Oracle.

  2. On the General tab, select the connection type.

    • SID: to connect by using a unique name of an Oracle instance (a process that runs on the workstation).

    • Service name: to connect by using an alias to an Oracle instance (or many instances).

    • URL only: to connect by providing the URL of a pre-built connection.

  3. Proceed based on the selected connection type:

    1. In the Host field, type your server address.

    2. In the Port field, type the port. The default port is 1521.

    3. In the SID field, specify a unique name of Oracle instance (a process that runs on the workstation).

    4. From the Driver list, select the Oracle JDBC driver mode to use with your connection:

      • Thin: the driver connects to the server directly.

      • OCI and OCI8: the driver uses native libraries to connect to the server.

    5. Under Authentication, select an authentication method:

      • User & Password: to use your login and password

      • No auth: to connect without authentication required

    6. In the User and Password fields, specify your credentials if required by the selected authentication method.

    1. In the Host field, type your server address.

    2. In the Port field, type the port. The default port is 1521.

    3. In the Service field, provide the alias to an Oracle instance that you want to use.

    4. From the Driver list, select the Oracle JDBC driver mode to use with your connection:

      • Thin: the driver connects to the server directly.

      • OCI and OCI8: the driver uses native libraries to connect to the server.

    5. Under Authentication, select an authentication method:

      • User & Password: to use your login and password

      • No auth: to connect without authentication required

    6. In the User and Password fields, specify your credentials if required by the selected authentication method.

    1. Under Authentication, select an authentication method:

      • User & Password: to use your login and password

      • No auth: to connect without authentication required

    2. In the User and Password fields, specify your credentials if required by the selected authentication method.

    3. In the URL field, provide the URL of the pre-built connection you want to establish.

  4. Click the Test connection button at the bottom of the dialog.

  5. Once the connection is successfully tested, click the Save and close button.

Results

  • If created for a specific notebook, the new connection will be automatically added to the workspace. You can later attach this database to any other notebook from this workspace.

  • If created for a workspace, this connection is added to the workspace databases and can be attached to any notebook from this workspace.

  • To retrieve and process data from the connected database, use SQL cells.
