Use the API Server and DB2 ADO.NET Provider to Access DB2 Data in Microsoft PowerPivot


Use the API Server to connect to live DB2 data in the PowerPivot business intelligence tool.

This article will explain how to use the API Server and the ADO.NET Provider for DB2 (or any of 200+ other ADO.NET Providers) to provide DB2 data as OData services and then consume the data in Microsoft Excel's PowerPivot business intelligence tool. Follow the steps below to retrieve and edit DB2 data in Power Pivot.

Set Up the API Server

Follow the steps below to begin producing secure DB2 OData services:

Deploy

The API Server runs on your own server. On Windows, you can deploy using the stand-alone server or IIS. On a Java servlet container, drop in the API Server WAR file. See the help documentation for more information and how-tos.

The API Server is also easy to deploy on Microsoft Azure, Amazon EC2, and Heroku.

Connect to DB2

After you deploy the API Server and the ADO.NET Provider for DB2, provide authentication values and other connection properties needed to connect to DB2 by clicking Settings -> Connections and adding a new connection in the API Server administration console.

Set the following properties to connect to DB2:

  • Server: Set this to the name of the server running DB2.
  • Port: Set this to the port the DB2 server is listening on.
  • Database: Set this to the name of the DB2 database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

You will also need to install the corresponding DB2 driver:

  • Windows: Install the IBM Data Server Provider for .NET.

    On Windows, installing the IBM Data Server Provider is sufficient, as the installation registers it in the machine.config.

  • Java: Install the IBM Data Server Driver for JDBC.

    In the Java version, place the IBM Data Server Driver JAR in the www\WEB-INF\lib\ folder for this application.

You can then choose the DB2 entities you want to allow the API Server access to by clicking Settings -> Resources.

Additionally, click Settings -> Server and set the Default Format to XML (Atom) for compatibility with Excel.

Authorize API Server Users

After determining the OData services you want to produce, authorize users by clicking Settings -> Users. The API Server uses authtoken-based authentication and supports the major authentication schemes. Access can also be restricted based on IP address; by default, only connections to the local machine are allowed. You can authenticate as well as encrypt connections with SSL.

Import DB2 Tables in Power Pivot

Follow the steps below to import tables that can be refreshed on demand:

  1. In Excel, click the PowerPivot Window icon in the PowerPivot tab to open PowerPivot.
  2. Click Home -> Get External Data -> From Data Service -> From OData Data Feed.

  3. Add authentication parameters. Click Advanced and set the Integrated Security option to Basic. You will need to enter the User Id and Password of a user who has access to the CData API Server. Set the password to the user's authtoken.

  4. In the Base URL box, enter the OData URL of the CData API Server. For example, http://localhost:8032/api.rsc.

  5. Select which tables you want to import and click Finish.

    6. You can now work with DB2 data in Power Pivot.
