Question

How to connect a Teradata database to RapidMiner Studio?

 

Note: This article does not cover Teradata Aster

Answer

The Teradata JDBC driver package includes two jar files, one containing the driver and another one with a config file in it. The driver only works when both files are linked via the classpath.

Step-by-step guide

Add the steps involved:

  1. Please download the appropriate JDBC drivers from Teradata and copy all its jar files to the folder "lib/jdbc" inside your RapidMiner Studio installation directory. This ensures that the driver classes are part of the java classpath.
  2. Next go to the database driver management dialog.
  3. For the jar file dialog manually enter both path statements comma separated to address both files (e.g. /path-to-rapidminer-folder/lib/jdbc/terajdbc4.jar,/path-to-rapidminer-folder/lib/jdbc/tdgssconfig.jar).
  4. Teradata JDBC drivers seem to offer no support for port settings. Please leave the port field blank, otherwise a connection cannot be established. 
  5. The driver setup should look similar to the setup shown in this image:
