Creating the Data Source Name
This section describes how to edit the DSN configuration and then authenticate and connect to Teradata APIs.
DSN Configuration
You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.
Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.
User DSN
Complete the following steps to edit the DSN configuration:
- Select Start > Search, and enter ODBC Data Sources in the Search box.
- Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
- Select the system data source and click Configure.
- Edit the information on the Connection tab and click OK.
System DSN
Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.
Deploying the Provider
To connect using the CData Power BI Connector for Teradata, you must install the Teradata .NET Data Provider into the GAC.
Connecting to Teradata
The connector wraps the official Teradata Database driver. You can connect to the CData Power BI Connector for Teradata using the same connection properties, and access the same functionality, as the underlying Teradata driver.
Required Properties
To connect to Teradata, set these properties:
- AuthScheme: Specify your Teradata server's required authentication mechanism: either TD2 (default) or LDAP.
- User: Teradata user username.
- Password: Teradata user password.
- DataSource: Specify the Teradata server name, DBC Name, or TDPID.
- Port: Specify the port the server is running on.
- Database: Specify the database name. If not specified, the connector connects to the default database.
