From the Oracle manual:
ENABLE NOVALIDATE means the constraint is checked for new or modified rows, but existing data may violate the constraint.

So you are looking for an incomplete constraint?


More likely they want to add a constraint but can't afford the time it would take to scan the table while holding an exclusive lock. At least that's the situation we're facing at work.

FWIW, I've been talking to Command Prompt about developing a fix for this, targeting inclusion in 8.5. I think Alvaro and I have come up with a reasonably plan, but there hasn't been time to present it to the community yet.
