Using the Oracle Database Adapter with Microsoft Office SharePoint Server

The WCF Adapter Service Development Wizard for Visual Studio 2010 enables the Microsoft BizTalk Adapter for Oracle Database and the Microsoft BizTalk Adapter for Oracle E-Business Suite to be directly consumed as an external datasource in Microsoft Office SharePoint Server 2010. The Add Service Development Wizard that supports this feature is launched with the WCF Adapter Service template for creating a new Visual C# Web Sites in Visual Studio 2010. The template is included with the BizTalk Adapter Pack 2010 . You must also install the Microsoft Windows Communication Foundation (WCF) Line of Business (LOB) Adapter SDK 2010.

The Adapter Service Development wizard generates a special service contract for the Oracle adapters that is compatible with Microsoft Office SharePoint Server 2010. The wizard will generate a service contract which includes the following operations for integrating the adapter with Microsoft Office SharePoint Server:

  • Create: Supported by the CreateItem_ operation.

  • Read: Supported by the ReadItem_ operation.

  • Update: Supported by the UpdateItem_ operation.

  • Delete: Supported by the DeleteItem_ operation.

  • Query: Supported by the ReadList operation.

  • Associate: Supported by the Associate_ operation.


The following service contract was generated using for the Microsoft BizTalk Adapter for Oracle Database as an example. The adapter is configured to provide access to the EMP table

[System.ServiceModel.ServiceContractAttribute()]
public interface ISCOTT_EMP {
    
    [System.ServiceModel.OperationContractAttribute()]
    SCOTT_EMP_Record[] ReadList(System.Nullable<int> Limit);
    
    [System.ServiceModel.OperationContractAttribute()]
    void CreateItem(SCOTT_EMP_Record Input);
    
    [System.ServiceModel.OperationContractAttribute()]
    SCOTT_EMP_Record[] ReadItem_EMPNO(System.Nullable<decimal> EMPNO);
    
    [System.ServiceModel.OperationContractAttribute()]
    void UpdateItem_EMPNO(SCOTT_EMP_Record Input);
    
    [System.ServiceModel.OperationContractAttribute()]
    void DeleteItem_EMPNO(System.Nullable<decimal> EMPNO);
    
    [System.ServiceModel.OperationContractAttribute()]
    SCOTT_EMP_Record[] Associate_DEPTNO(System.Nullable<decimal> DEPTNO);
}

These steps provide an example using the WCF Adapter Service Development Wizard, to create a new WCF web service hosting the Microsoft BizTalk Adapter for Oracle Database. The service contract will include operations directly compatible with Microsoft Office Sharepoint Server 2010. So that it can be directly consumed as an external datasource. The adapter is configured to authenticate with the Oracle database using the SCOTT account. If the SCOTT account is locked, you can unlock the account by logging into SQL Plus as SYSDBA.

<Oracle Installation Bin Directory>\Sqlplus.exe SYS AS SYSDBA

Then run the following command.

SQL> ALTER USER scott ACCOUNT UNLOCK;

Creating the New Web Site Project

  1. Click Start, point to All Programs, point to Microsoft Visual Studio 2010, and then click Microsoft Visual Studio 2010.

  2. In Visual Studio 2010, on the File menu, select New and then click Project.

  3. In the New Project dialog box, expand Other Languages and click Visual C#. Find the WCF Adapter Service in the template list and click it to select it.

    Gg162735.note(en-us,BTS.70).gifNote
    The WCF Adapter Service template is not available if the BizTalk Adapter Pack 2010 is not installed. On x64 systems, install both the x86 and x64 versions of the BizTalk Adapter Pack 2010 .

  4. Specify ScottEMP for the name, and then click OK. The WCF Adapter Service Development Wizard starts.

  5. On the Introduction page, click Next.

  6. On the Choose Operations page, specify the oracleDBBinding binding.

  7. Click the Configure button. The Configure Adapter dialog is displayed.

  8. On the Security tab, select Username in the Client credential type dropdown list box.

  9. Enter SCOTT for the User name and enter the correct password for the SCOTT account. The default password for the SCOTT account is tiger.

  10. Click the URI Properties tab, enter the IP address or host name for your Oracle server in the ServerAddress box.

  11. Enter the correct Oracle database service instance name in the ServiceName box. You can copy the instance name information from Oracle Enterprise Manager.

  12. Press the OK button on the Configure Adapter dialog

  13. On the Choose Operations page of the wizard, click the Connect button and wait a few moments for the categories to be built for the Oracle database.

  14. Once the categories are added in the Select a category list, scroll down to SCOTT and expand it. Then expand Table and click the EMP table entry.

  15. In the Available categories and operations list, select all the operations in the list and click the Add button. All the operations are added to the Added categories and operations list.

  16. On the Choose Operations page, click the Next button.

  17. On the Configure Service and Endpoint Behaviors page, set the UseServiceCertificate Service behavior to false for this example. Then click the Next button.

  18. On the Configure Service Endpoint Binding and Address page, click the Apply button. Then click the Next button.

  19. On the Summary page, click the Finish button.

  20. Click the Build menu option and then click Build Solution. Verify the project build was successful with no errors.

For this example you will publish the adapter host service to the local IIS web server.

  1. In Solution Explorer for Visual Studio 2010, right click the ScottEmp project and click Properties. The Project Designer tabs are displayed.

  2. Click the Web tab, then click the Use Local IIS Web server option.

  3. Click the Create Virtual Directory button.

  4. Open a web browser to the service address http://localhost/ScottEmp/ISCOTT_EMP.svc. You should receive a message stating “You have created a service” indicating the adapter is hosted in IIS.

This section describes how to add the WCF Service as an external data source to a new Web Site using SharePoint Designer.

Adding the External Data source

  1. Open SharePoint Designer and create a new Web Site.

  2. In SharePoint Designer, expand Navigation and click External Content types in the Site Objects list.

  3. Click the External Content Type menu button to create a new external content type.

  4. Click the text beside Name to edit the name of the new external content type. Enter OracleEMP for the name.

  5. Click the text link beside External System which says Click here to discover external data sources and operations.. This opens the Operation Designer for the OracleEMP external content type.

  6. Click the Add Connection button on the discovery screen.

  7. In the External Data Source Type Selection dialog, choose WCF Service and click the OK button.

  8. In the WCF Connection dialog, in the Service Metadata URL box enter https://localhost/ScottEmp/ISCOTT_EMP.svc?wsdl

  9. In the Service Endpoint URL box enter https://localhost/ScottEmp/ISCOTT_EMP.svc

  10. Click the OK button to close the WCF Connection dialog.

  11. Once the Data Source information is populated, expand the https://localhost/ScottEmp/ISCOTT_EMP.svc data source and expand Web Methods.

  12. Right click the ReadList Web Method and click New Read List Operation. The Read List configuration dialog is launched.

  13. In the Read List dialog click Return Parameters and click EMPNO in the Data Source Elements. Click the Map to identifier.

  14. Click Finish in the Read List dialog.

  15. Save the new external data source by typing Ctrl+s.

Testing the External Data Source Connection

  1. In the new web site, click the Create Lists and Forms button. The Create List and Form for OracleEMP dialog appears.

  2. Enter OracleEMP_List for the List Name and click the OK button.

  3. Once the list is create, click the Summary View button on the menu.

  4. Click OracleEMP_List under External Lists.

  5. Click the Preview in Browser button on the menu to test the ReadList operation of the adapter.

  • On 64-bit machines you must make sure that 32-bit Oracle client components are also installed. This is because Visual Studio 2010 and it’s wizards will be running as a 32-bit process requiring access to 32-bit components during development.
