This section describes how to edit the DSN configuration and then authenticate and connect to DB2 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:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. 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.

Connecting to DB2

Set the following properties to connect:

• Server: The name of the server running DB2.
• Port: The port the DB2 server is listening on.
• Database: The name of the DB2 database.

Authenticating to DB2

The connector supports authenticating directly to the DB2 with user credentials as well as authenticating using the API key of an application integrated with DB2, such as Watson Query.

DB2 User Credentials

Set AuthScheme to USRIDPWD. Provide the following credentials:

• User: The username of a user with access to the database.
• Password: The password of a user with access to the database.

IAM

The connector supports authenticating to the DB2 server using the API key of an application that connects to it, such as Watson Query.

Set AuthScheme to IBMIAMAuth. Provide the following credentials:

• User: The IBMid or service ID tied to a user of the DB2 server.
• Password: The API key associated with the application that requires access to the DB2 database.
