Like others have mentioned, cloning provides you with the ability to
take a copy of a production environment and use it for development,
testing patches and configuration changes before you make them into
production, etc.
There are a couple of ways to clone a database but the easiest is to
use RMANs duplicate feature. Its very easy to automate a clone and I
even have some databases which are refreshed nightly with a copy of
production.
