Windows DSN Configuration
Using the Microsoft ODBC Data Source Administrator
You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the DSN is created during the installation process.
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 application (32-bit or 64-bit).
- Click the System DSN tab.
- Select the system data source and click Configure.
- Edit the information on the Connection tab and click OK.
Note: For .NET Framework 4.0, the driver distributes Microsoft Visual C++ 2015-2022 Redistributable. For .NET Framework 3.5, the driver distributes Microsoft Visual C++ 2008 Redistributable.
Ensuring Registry Access
The driver stores connection information in the Windows registry. To ensure that the driver can write to the registry, perform either of the following actions:
- Run the calling application as an administrator.
- Connect via a User DSN instead of a System DSN.
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 driver 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 driver 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.
