Connect to Oracle Eloqua Reporting Data as an External Source in Dremio

The CData JDBC Driver for Oracle Eloqua Reporting implements JDBC Standards and allows various applications, including Dremio, to work with live Oracle Eloqua Reporting data. Dremio is a data lakehouse platform designed to empower self-service, interactive analytics on the data lake. With the CData JDBC driver, you can include live Oracle Eloqua Reporting data as a part of your enterprise data lake. This article describes how to connect to Oracle Eloqua Reporting data from Dremio as an External Source.

The CData JDBC Driver enables high-speed access to live Oracle Eloqua Reporting data in Dremio. Once you install the driver, authenticate with Oracle Eloqua Reporting and gain immediate access to Oracle Eloqua Reporting data within your data lake. By surfacing Oracle Eloqua Reporting data using native data types and handling complex filters, aggregations, & other operations automatically, the CData JDBC Driver grants seamless access to Oracle Eloqua Reporting data.

Prerequisites

This article assumes you are utilizing Docker to run Dremio. You can create a Docker container with the Dremio service using a command similar to the follow:

docker run -d --name dremio -p 9047:9047 -p 31010:31010 dremio/dremio-oss

Where dremio is the name of the container, 9047 is the container's port for the Dremio web interface and 31010 is the port that maps to the Dremio query service. dremio/dremio-oss specifies the image to use.

Build the ARP Connector

To use the CData JDBC Driver in Dremio, you need to build an Advanced Relation Pushdown (ARP) Connector. You can view the source code for the Connector on GitHub or download the ZIP file (GitHub.com) directly. Once you copy or extract the files, run the following command from the root directory of the connector (the directory containing the pom.xml file) to build the connector.

mvn clean install

NOTE: The CData ARP Connectors are build to be compiled with Java 11. Be sure to install Java 11 and use the correct version. You can update your Java version using a command similar to the following:

sudo update-alternatives --config java

Once the JAR file for the connector is built (in the target directory), you are ready to copy the ARP connector and JDBC Driver to your Dremio instance.

Installing the Connector and JDBC Driver

Install the ARP Connector to %DREMIO_HOME%/jars/ and the JDBC Driver for Oracle Eloqua Reporting to %DREMIO_HOME%/jars/3rdparty. You can use commands similar to the following:

ARP Connector

docker cp PATH\TO\dremio-oracleeloquareporting-plugin-{DREMIO_VERSION}.jar dremio_image_name:/opt/dremio/jars/

JDBC Driver for Oracle Eloqua Reporting

docker cp PATH\TO\cdata.jdbc.oracleeloquareporting.jar dremio_image_name:/opt/dremio/jars/3rdparty/

Connecting to Oracle Eloqua Reporting

Oracle Eloqua Reporting will now appear as an External Source option in Dremio. The ARP Connector built uses a JDBC URL to connect to Oracle Eloqua Reporting data. The JDBC Driver has a built-in connection string designer that you can use (see below).

Built-in Connection String Designer

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

java -jar cdata.jdbc.oracleeloquareporting.jar

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

Oracle Eloqua Reporting supports the following authentication methods:

• Basic authentication (User and Password)
• OAuth 2.0 code grant flow
• OAuth 2.0 password grant flow

Basic Authentication (User and Password)

To perform authentication with a user and password, specify these properties:

• AuthScheme: Basic.
• Company: The company name associated with your Oracle Eloqua Reporting account.
• User: Your login account name.
• Password: Your login password.

OAuth Authentication (Code Grant Flow)

To authenticate with the OAuth code grant flow, you must set AuthScheme to OAuth and create a custom OAuth application. For information about how to create a custom OAuth application, see the Help documentation.

Then set the following properties:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• OAuthClientId: The client Id assigned when you registered your application.
• OAuthClientSecret: The client secret that was assigned when you registered your application.
• CallbackURL: The redirect URI that was defined when you registered your application.

When you connect, the driver opens Oracle Eloqua Reporting's OAuth endpoint in your default browser. Log in and grant permissions to the application. When the access token expires, the driver refreshes it automatically.

OAuth Authentication (Password Grant Flow)

With the OAuth password grant flow, you can use your OAuth application's credentials alongside your user credentials to authenticate without the need to grant permission manually via a browser prompt. You must create an OAuth app (see the Help documentation) to use this authentication method.

Set the following properties:

• AuthScheme: OAuthPassword
• Company: The company's unique identifier.
• User: Your login account name.
• Password: Your login password.
• OAuthClientId: The client Id assigned when you registered your custom OAuth application.
• OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

👁 Using the built-in connection string designer to generate a JDBC URL (Salesforce is shown.)

NOTE: To use the JDBC Driver in Dremio, you will need a license (full or trial) and a Runtime Key (RTK). For more information on obtaining this license (or a trial), contact our sales team.

Add the Runtime Key (RTK) to the JDBC URL. You will end up with a JDBC URL similar to the following:

jdbc:oracleeloquareporting:RTK=5246...;AuthScheme=Basic;User=user;Password=password;Company=MyCompany;

Access Oracle Eloqua Reporting as an External Source

To add Oracle Eloqua Reporting as an External Source, click to add a new source and select OracleEloquaReporting. Copy the JDBC URL and paste it into the New OracleEloquaReporting Source wizard.

👁 Entering the JDBC URL (Amazon DynamoDB is shown)

Save the connection and you are ready to query live Oracle Eloqua Reporting data in Dremio, easily incorporating Oracle Eloqua Reporting data into your data lake.
