Oracle Database Connections

Note

This feature may not be available in all product editions. For more information on available features, see Compare Editions.

You can create connections to one or more Oracle Database from the Alteryx Analytics Cloud.

Tip

You can create connections to databases of this type that are managed by your enterprise or are hosted in cloud infrastructure. The required configuration is the same. The cloud-based version is labeled on Amazon RDS. In the Create Connection dialog, you can search for that term.

Note

You cannot disable type inference for Oracle sources. This is a known issue.

If you are connecting the Alteryx Analytics Cloud to any relational source of data, you must add the Alteryx Service to your whitelist for those resources. See Whitelist Platform Service.

Supported Versions: 12.1.0.2

  • Read: Supported

Configure

To create this connection:

  • In the Import Data page, click the Plus sign. Then, select the Relational tab. Click the Oracle Database card.

  • You can also create connections through the Connections page. See Connections Page.

Modify the following properties as needed:

Property

Description

Host

Enter your hostname. Example:

testsql.database.windows.net

Port

Set this value to 1521.

Connect String options

Please insert any connection options as a string here. See below.

Enable SSL

Select the option if the connection should use SSL.

Note

Additional configuration may be required in the database server. For more information, please consult the documentation that was provided with the distribution.

Note

SSL connections are not supported in the Alteryx Analytics Cloud.

Service Name

Enter the name of the Oracle service.

User Name

(basic credential type only) Username to use to connect to the database.

Password

(basic credential type only) Password associated with the above username.

Test Connection

After you have defined the connection credentials type, credentials, and connection string, you can validate those credentials.

Advanced options: Enable SSH Tunneling

If available, the SSH tunneling options allow you to configure SSH tunneling authentication between the Trifacta Application and your database.

Note

SSH tunneling is available on a per-connection basis. It may not be available for all connections.

For more information, see Configure SSH Tunnel Connectivity.

Connection Name

Display name of the connection

Connection Description

Description of the connection, which appears in the application.

Connection URL

The properties that you provide are inserted into the following URL, which connects the Alteryx Analytics Cloud to the connection:

<host>:<port>/<service_name>

Connect string options

The connect string options are optional. If non-standard connections are required, Oracle Database supports using tsnames format.

When the connect string options field is used:

  • The connect string options parameters are prepended with jdbc:oracle:thin:@.

  • The following fields are ignored from the form. These values must be specified as part of the tsnames :

    • Host

    • Port

    • Service

    • SSL

After you specify the connect string options, the generated connection URL is automatically prepended with the following protocol information. Do not add this to the connection URL or connect string options:

jdbc:oracle:thin:@

Examples are below.

Use SID:

If you are using a service identifier, instead of a service name, please specify your connection string options as follows:

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=oracle.rds.example.com)(PORT=1521))(CONNECT_DATA=(SID=orcl)))

Use TCPS:

If TCPS protocol is required, you can specify your connection string options as follows:

(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)(HOST=oracle.rds.example.com)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=orcl)))

For more information, please see the documentation for the Oracle Database driver.
