Use the API Server and Oracle ADO.NET Provider to Access Oracle Data in Microsoft PowerPivot
Use the API Server to connect to live Oracle data in the PowerPivot business intelligence tool.
This article will explain how to use the API Server and the ADO.NET Provider for Oracle (or any of 200+ other ADO.NET Providers) to provide Oracle 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 Oracle data in Power Pivot.
Set Up the API Server
Follow the steps below to begin producing secure Oracle 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 Oracle
After you deploy the API Server and the ADO.NET Provider for Oracle, provide authentication values and other connection properties needed to connect to Oracle by clicking Settings -> Connections and adding a new connection in the API Server administration console.
To connect to Oracle, you'll first need to update your PATH variable and ensure it contains a folder location that includes the native DLLs. The native DLLs can be found in the lib folder inside the installation directory. Once you've done this, set the following to connect:
- Port: The port used to connect to the server hosting the Oracle database.
- User: The user Id provided for authentication with the Oracle database.
- Password: The password provided for authentication with the Oracle database.
- Service Name: The service name of the Oracle database.
You can then choose the Oracle 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 Oracle Tables in Power Pivot
Follow the steps below to import tables that can be refreshed on demand:
- In Excel, click the PowerPivot Window icon in the PowerPivot tab to open PowerPivot.
- Click Home -> Get External Data -> From Data Service -> From OData Data Feed.
-
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.
-
In the Base URL box, enter the OData URL of the CData API Server. For example, http://localhost:8032/api.rsc.
-
Select which tables you want to import and click Finish.
You can now work with Oracle data in Power Pivot.
