Connect to Oracle Autonomous Data Warehouse

You can create a connection to Oracle Autonomous Data Warehouse and use the connection to access data.

Before you start, ask your Autonomous Data Warehouse (ADW) administrator to configure ADW to allow access from Oracle Analytics Cloud. The configuration steps that administrators follow are different for public and private types of connection:

• For public connections, see Enable Access to Oracle Autonomous Data Warehouse Prerequisites.
• For private connections, see How do I connect to a private Oracle Autonomous Data Warehouse in a customer VCN?.

You can connect to Oracle Autonomous Data Warehouse using security certificates downloaded from Oracle Autonomous Data Warehouse to a wallet (known as mTLS, or Mutual Transport Layer Security), or without a wallet (known as TLS, or Transport Layer Security). The credentials wallet file secures communication between Oracle Analytics and Oracle Autonomous Data Warehouse. The wallet file (for example, wallet_ADWC1.zip) that you upload must contain SSL trusted certificates, to enable SSL on your Oracle Database Cloud connections.

Tutorial

1. To connect using a credentials wallet file, (known as Mutual TLS connection), download the SSL certificates from Oracle Autonomous Data Warehouse.

   See Download Client Credentials (Wallets) in Using Oracle Autonomous Database Serverless.

   The credentials wallet file secures communication between Oracle Analytics and Oracle Autonomous Data Warehouse. The wallet file (for example, wallet_ADWC1.zip) that you upload must contain SSL certificates.

   To connect without using a credentials wallet file (known as TLS connection), skip Step 1 and go straight to the Step 2.

2. On the Home page, click Create then click Connection.
3. Click Oracle Autonomous Data Warehouse.
4. Enter a user-friendly Connection Name and Description.
5. For Encryption Type:
   • To connect without a credentials wallet file, select TLS as the Encryption Type, enter a Connection String, then enter a Username and Password of a user in Oracle Autonomous Data Warehouse.
   • To connect using a credentials wallet file, select Mutual TLS as the Encryption Type, then click Select and browse for and select the Client Credentials wallet file that you downloaded from Oracle Autonomous Data Warehouse (for example, wallet_ADWC1.zip), then enter a Service Name. The Client Credentials field displays the cwallet.sso file. See Selecting an Oracle Autonomous Data Warehouse Database Service Name.

     Tip: If you define the Oracle Autonomous Data Warehouse connection using an instance wallet, the high service name is selected by default. Change the name to low or medium to avoid limiting the number of concurrent connections.

6. If you're connecting to a remote database, click Use Remote Data Connectivity.
   Check with your administrator that you can access the remote database.
7. If you want data modelers to be able to use these connection details. click System connection. See Database Connection Options.
8. Click Save.

You can now create datasets from the connection.
