Connect to ServiceNow Data in RapidMiner

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

Connect to ServiceNow in RapidMiner as a JDBC Data Source

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

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

   ServiceNow uses the OAuth 2.0 authentication standard. To authenticate using OAuth, you will need to register an OAuth app with ServiceNow to obtain the OAuthClientId and OAuthClientSecret connection properties. In addition to the OAuth values, you will need to specify the Instance, Username, and Password connection properties.

   See the "Getting Started" chapter in the help documentation for a guide on connecting to ServiceNow.

   Built-in Connection String Designer

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

   java -jar cdata.jdbc.servicenow.jar

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

   A typical connection string is below:

   OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;Username=MyUsername;Password=MyPassword;Instance=MyInstance;InitiateOAuth=GETANDREFRESH
10. Enter your username and password if necessary.

You can now use your ServiceNow connection with the various RapidMiner operators in your process. To retrieve ServiceNow 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 ServiceNow data.
