RE: redo curiosity

It probably doesn't need to be said but just to be sure:

Atomic refreshes are there for a reason.  Make sure you understand the 
repercussions of using that parameter.  I don't believe you stated the 
additional redo as a problem; only that it was different from previous 
versions.  Atom refreshes ensure that you don't end up with empty materialized 
views.

Thanks!  That's definitely worth a try.  I'll add this to our large refreshes 
to see what
difference it makes tonight.
