Which has the higher priority in your organization: Deploying a new database or securing the ones you already have? Looking for a website, and resources, dedicated solely to securing Oracle databases? Check out DBSecWorx.

Purpose Encapsulates undo logic for removing Java system objects during upgrade/downgrade and for full removal of Java to back out of the results of a failed initjvm.

The package contains private objects not exposed via the package specification.

Warning: The RUN and STRIP objects in this package are destructive. Executing them will totally destroy an Oracle Database. The examples here are for education purposes only and not intended to encourage anyone to believe they are safe to execute.
