IBM Informix JDBC Driver

Rapidly create and deploy powerful Java applications that integrate with IBM Informix.



Integrate IBM Informix data with standard components and data source configuration wizards in RapidMiner Studio.

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

Connect to IBM Informix in RapidMiner as a JDBC Data Source

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

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

    Set the following properties to connect to IBM Informix

    • Server: Set this to the name of the server running IBM Informix.
    • Port: Set this to the port the IBM Informix server is listening on.
    • Database: Set this to the name of the IBM Informix database.
    • User: Set this to the username of a user allowed to access the database.
    • Password: Set this to the password of a user allowed to access the database.

    Built-in Connection String Designer

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

    java -jar cdata.jdbc.informix.jar

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

    A typical connection string is below:

    Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;
  10. Enter your username and password if necessary.

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