Hello Chuck;
I Googled it when you said that as it surprised me. The answer I
found was that it did not.
Hmmm darn. I was hoping that I had spelt deferred wrong or
something. :)
I see DB2 has a feature to turn constraints off/on inside a
transaction so I am guessing it would be possible to create a
JDBCAdaptor subclass that automatically did that sort of thing
when it goes to perform adaptor operations on a channel.

Yes, that would be possible. But does that mean you can commit
data that violates the constaints?
I _think_ I am reading that it can play catch-up from when you turn
it back on again.
That could OK then. You would have (want) to create an exception with
enough info to identify the constraint downstream.
