Connect to Oracle HCM Cloud Data in RapidMiner

This article shows how you can easily integrate the CData JDBC driver for Oracle HCM Cloud into your processes in RapidMiner. This article uses the CData JDBC Driver for Oracle HCM Cloud to transfer Oracle HCM Cloud data to a process in RapidMiner.

Connect to Oracle HCM Cloud in RapidMiner as a JDBC Data Source

You can follow the procedure below to establish a JDBC connection to Oracle HCM Cloud:

1. Add a new database driver for Oracle HCM Cloud: Click Connections -> Manage Database Drivers.
2. In the resulting wizard, click the Add button and enter a name for the connection.
3. Enter the prefix for the JDBC URL:

   jdbc:oraclehcm:
   

4. Enter the path to the cdata.jdbc.oraclehcm.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class:

   cdata.jdbc.oraclehcm.OracleHCMDriver
   

   👁 The JDBC driver configuration. (Salesforce is shown.)
   
6. Create a new Oracle HCM Cloud connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Oracle HCM Cloud driver you configured previously.
9. Enter your connection string in the Host box.

   Using Basic Authentication

   You must set the following to authenticate to Oracle HCM Cloud:

   • Url: The Url of your account.
   • User: The user of your account.
   • Password: The password of your account.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.oraclehcm.jar
   

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

   A typical connection string is below:

   Url=https://abc.oraclecloud.com;User=user;Password=password;
   

10. Enter your username and password if necessary. 👁 The connection to the JDBC data source. (Salesforce is shown.)
    

You can now use your Oracle HCM Cloud connection with the various RapidMiner operators in your process. To retrieve Oracle HCM Cloud data, drag the Retrieve operator from the Operators view. 👁 A Retrieve operation to select data. (Salesforce is shown.)
With the Retrieve operator selected, you can then define which table to retrieve in the Parameters view by clicking the folder icon next to the "repository entry." In the resulting Repository Browser, you can expand your connection node to select the desired example set.

Finally, wire the output to the Retrieve process to a result, and run the process to see the Oracle HCM Cloud data.
