Goal

To explain how to remove System, User and File Data Source Names (DSNs) from the Windows Registry along with the Oracle ODBC Driver used to create the DSN.

Sometimes the typical process of using the ODBC Data Source Administrator does not work. Users may want to know what registry keys the Oracle ODBC Driver creates when the driver is installed and Oracle DSNs are created.

Additionally, users may encounter an Oracle ODBC Driver who's version is listed as "Not-Marked" when viewing it in the ODBC Data Source Administrator. These steps will show you how to manually remove DSNs and unregister the Oracle ODBC Driver from the registry resolving any "Not-Marked" issues.
