Connect to Oracle SCM Data in RapidMiner

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

Connect to Oracle SCM in RapidMiner as a JDBC Data Source

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

1. Add a new database driver for Oracle SCM: 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:oraclescm:
4. Enter the path to the cdata.jdbc.oraclescm.jar file, located in the lib subfolder of the installation directory.
5. Enter the driver class: cdata.jdbc.oraclescm.OracleSCMDriver
6. Create a new Oracle SCM connection: Click Connections -> Manage Database Connections.
7. Enter a name for your connection.
8. For Database System, select the Oracle SCM driver you configured previously.
9. Enter your connection string in the Host box.

   The following connection properties are required to connect to Oracle SCM data.

   • Url: The URL of the account that you want to connect to. Typically, this will be the URL of your Oracle Cloud service. For example, https://servername.fa.us2.oraclecloud.com.
   • User: The username of your Oracle Cloud service account.
   • Password: The password of your Oracle Cloud service account.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.oraclescm.jar

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

   A typical connection string is below:

   Url=https://myinstance.oraclecloud.com;User=user;Password=password;
10. Enter your username and password if necessary.

You can now use your Oracle SCM connection with the various RapidMiner operators in your process. To retrieve Oracle SCM data, drag the Retrieve operator from the Operators view. 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 SCM data.
