Bridge Oracle Eloqua Connectivity with Apache NiFi

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

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

Connecting to Oracle Eloqua Data in Apache NiFi

1. Download the CData JDBC Driver for Oracle Eloqua 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.oracleeloqua.jar (and cdata.jdbc.oracleeloqua.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 Oracle Eloqua.

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:

    Property	Value
    Database Connection URL	jdbc:oracleeloqua:User=user;Password=password;Company=CData;
    Database Driver Class Name	cdata.jdbc.oracleeloqua.OracleEloquaDriver

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.oracleeloqua.jar

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

    There are two authentication methods available for connecting to Oracle Eloqua: Login and OAuth. The Login method requires you to have the Company, User, and Password of the user.

    If you do not have access to the username and password or do not wish to require them, you can use OAuth authentication. OAuth is better suited for allowing other users to access their own data. Using login credentials is better suited for accessing your own data.

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

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