There's a number of legitimate ways to go about this.
At one clients facility, we would have separate systems with their own individual Oracle installations and databases on each one. Doing it this way, we we're also able to test out operating system patch sets with no repercussions to production.
That particular client is also in a regulated industry so they usually had separate production, pre-production, and development environments.
I'd probably think about having at least two separate systems - be they physical or virtual. That way, you can test both operating system and Oracle updates without affecting production. Just my own take on it.
