Hello, we have a development Oracle ZAM Environment so we can test upgrades and have a sandbox for our Software Managers to learn in.

The question I have is sometimes we will restore our production database into development so we have data to play with.

What is the easiest way to go back to scratch where we have no Hardware or Software information?

We tried it from the database by purging some tables and ended up losing everything all user information and then I couild not log back in?

Is there an easy way to purge all data?
