From the Oracle manual:

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.
