SAP HANA XS Advanced JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with SAP HANA XS Advanced.



Access and process SAP HANA XS Advanced data in Apache NiFi using the CData JDBC Driver.

Apache NiFi supports powerful and scalable directed graphs of data routing, transformation, and system mediation logic. When paired with the CData JDBC Driver for SAP HANA XS Advanced, NiFi can work with live SAP HANA XS Advanced data. This article describes how to connect to and query SAP HANA XS Advanced data from an Apache NiFi Flow.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live SAP HANA XS Advanced data. When you issue complex SQL queries to SAP HANA XS Advanced, the driver pushes supported SQL operations, like filters and aggregations, directly to SAP HANA XS Advanced 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 HANA XS Advanced data using native data types.

Connecting to SAP HANA XS Advanced Data in Apache NiFi

  1. Download the CData JDBC Driver for SAP HANA XS Advanced installer, unzip the package, and run the JAR file to install the driver.
  2. Copy the CData JDBC Driver JAR file (and license file if it exists), cdata.jdbc.saphanaxsa.jar (and cdata.jdbc.saphanaxsa.lic), to the Apache NiFi lib subfolder, for example, C:\nifi-1.3.0-bin\nifi-1.3.0\lib.

    On Windows, the default location for the CData JDBC Driver is C:\Program Files\CData\CData JDBC Driver for SAP HANA XS Advanced.

  3. Start Apache NiFi. For example:

    cd C:\nifi-1.3.0-bin\nifi-1.3.0\bin
    run-nifi.bat
    
  4. Navigate to the Apache NiFi UI in your web browser: typically http://localhost:8080/nifi
  5. Click the (Configuration) button from the Operate sidebar.
  6. In the NiFi Flow Configuration page, navigate to the Controller Services tab.
  7. Click the button to create a new controller service.
  8. In the Add Controller Service page, select DBCPConnection Pool, and then click Add.
  9. Click the gear button to configure the new DBCPConnection Pool.
  10. In the Configure Controller Service page, navigate to the Properties tab. Fill in the properties:

    PropertyValue
    Database Connection URLjdbc:saphanaxsa:OAuthClientID=my-ouath-client-id;OAuthClientSecret=my-oauth-client-secret;URL=https://hxehost:51027/euro.xsodata;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH
    Database Driver Class Namecdata.jdbc.saphanaxsa.SAPHanaXSADriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.saphanaxsa.jar

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

    SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See the OAuth section in the Help documentation for a guide.

  11. Click the button to enable the new DBCPConnection Pool.

Your SAP HANA XS Advanced data is now available for use in Apache NiFi. For example, you can use the DBCPConnection Pool as the source for a QueryDatabaseTable processor.
