Create an SAP Netweaver Gateway Data Source for Denodo Platform

Use the CData JDBC Driver for SAP Netweaver Gateway to create a virtual data source for SAP Netweaver Gateway data in the Denodo Virtual DataPort Administrator.

Denodo Platform is a data virtualization product providing a single point of contact for enterprise database data. When paired with the CData JDBC Driver for SAP Netweaver Gateway, Denodo users can work with live SAP Netweaver Gateway data alongside other enterprise data sources. This article walks through creating a virtual data source for SAP Netweaver Gateway in the Denodo Virtual DataPort Administrator.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SAP Netweaver Gateway data. When you issue complex SQL queries to SAP Netweaver Gateway, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP Netweaver Gateway and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze SAP Netweaver Gateway data using native data types.

Create an SAP Netweaver Gateway Virtual Port

To connect to live SAP Netweaver Gateway data from Denodo, you need to copy the JDBC Driver JAR file to the external library directory for Denodo and create a new JDBC Data Source from the Virtual DataPort Administrator tool.

  1. Download the CData JDBC Driver for SAP Netweaver Gateway installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the JAR File (and license file if it exists) from the installation location (typically C:\Program Files\CData\CData JDBC Driver for SAP Netweaver Gateway\lib\) to the Denodo external library directory (C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-sapgateway-19).
  3. Open the Denodo Virtual DataPort Administrator tool and navigate to the Server Explorer tab.
  4. Right-click "admin" and select New -> Data source -> JDBC.
  5. Configure the JDBC Connection:
    • Name: your choice, e.g.: sapgateway
    • Database adapter: Generic
    • Driver class path: C:\Denodo\Denodo Platform\lib-external\jdbc-drivers\cdata-sapgateway-19
    • Driver class: cdata.jdbc.sapgateway.SAPGatewayDriver
    • Database URI: Set this to a JDBC URL using the necessary connection properties. For example,

      jdbc:sapgateway:User=user;Password=password;URL=https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/;InitiateOAuth=GETANDREFRESH

      Information on creating the Database URI follows:

      Built-In Connection String Designer

      For assistance in constructing the JDBC URL, use the connection string designer built into the SAP Netweaver Gateway JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

      java -jar cdata.jdbc.sapgateway.jar

      Fill in the connection properties and copy the connection string to the clipboard.

      SAP Gateway allows both basic and OAuth 2.0 authentication. You can use basic authentication to connect to your own account, or you can use OAuth to enable other users to retrieve data from your service with their accounts. In addition to authenticating, set the following connection properties to access SAP Gateway tables.

      • Url: Set this to the URL of your environment, or to the full URL of the service. For example, the full URL might appear as: https://sapes5.sapdevcenter.com/sap/opu/odata/IWBEP/GWSAMPLE_BASIC/. In this example, the environment URL would just be: https://sapes5.sapdevcenter.com.
      • Namespace: Set the appropriate Service Namespace. In the example above, IWBEP is the namespace. It is optional if the full URL to the service is specified.
      • Service: Set this to the service you want to retrieve data from. In the example above, the service is GWSAMPLE_BASIC. It is not required if the full URL is specified.

      Authenticate via Basic Authentication

      In basic authentication, you use your login credentials to connect. Set the following properties:

      • User: This is the username you use to log in to SAP Gateway.
      • Password: This is the password you use to log in to SAP Gateway.

      Authenticate via OAuth Authentication

      You can connect to SAP Gateway using the embedded OAuth connectivity (without setting any additional authentication connection properties). When you connect, the OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

  6. Click the "Test connection" button to confirm the configuration and click Save.

View SAP Netweaver Gateway Data in the VirtualPort Administrator Tool

After creating the data source, you can create a base view of SAP Netweaver Gateway data for use in the Denodo Platform.

  1. Click the "Create base view" button in the newly created VirtualPort (admin.SAPGateway).
  2. Expand the object tree and select the objects (tables) you wish to import.
  3. Click the "Create selected" button to create views of the SAP Netweaver Gateway data.
    Optional: Click "Create associations from foreign keys" to define relationships between the objects.
  4. With the view(s) created, navigate to a table (cdata_sapgateway_salesorderlineitems) in the Server Explorer and double-click the selected table.
  5. In the new tab, click "Execution panel" to open a query panel.
  6. Customize the query in the "Execute" tab or use the default:
    SELECT * FROM cdata_sapgateway_salesorderlineitems CONTEXT ('i18n'='us_est', 'cache_wait_for_load'='true')
    
  7. Click Execute to view the data.

With the base view created, you can now work with live SAP Netweaver Gateway data like you would any other data source in Denodo Platform, for example, querying SAP Netweaver Gateway in the Denodo Data Catalog.
