Connect to PowerShell Scripts in RapidMiner

Integrate PowerShell scripts with standard components and data source configuration wizards in RapidMiner Studio.

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

Connect to PowerShell in RapidMiner as a JDBC Data Source

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

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

    The ScriptLocation, under the Data section, must be set to a valid script location.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.powershell.jar

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

    A typical connection string is below:

    ScriptLocation='%Public%\Documents\CData PowerShell Scripts';ExecuteQuery=True;
  10. Enter your username and password if necessary.

You can now use your PowerShell connection with the various RapidMiner operators in your process. To retrieve PowerShell scripts, 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 PowerShell scripts.
