For example, suppose you want to add support for MySQL. (As of OWB 11g R2, MySQL is not on the list of supported by default platforms.) All you need to do, though, is download the MySQL JDBC driver to put it into the OWB_HOME/owb/lib/ext directory, and add the platform definition for MySQL via a Tcl script that you can run from the OMB Plus console. The contents of such a script is beyond the scope of this article. However, if you want to look at one, check out this post by David Allan, where you’ll find a detailed example of how you can add support for MySQL to Oracle Warehouse Builder 11g Release 2. Also, there is a whitepaper on OTN called the "OWB Platform and Application Adapter Extensibility Cookbook", which goes into more depth than David’s post.
