Dennis, 

We do almost the same thing that you described. 

We have a 140G database. Everyday we *clone* that production database and
call it 'DAYOLD'. This database is used by app support to investigate data
related issues and bugs. But a day before release, we run *all* scripts sent
in by developers on this database. It they fail on dayold database, the
whole request (and any dependencies) are pulled from the release, if not
fixed within 30 minutes from reporting.

It has been working very well for us for more than 8 months. We clone 4 such
databases of varying sizes everyday. These usually get refreshed after the
hot backup on the specific database. The cloning process (and locking down
of schema and scrambling of sensitive information is part of cloning) is
usually finished by 5:30am except Sunday.

Yes, and we use the same script on production ... with different passwords.
What do you do for multi-schema releases? We change passwords of all schema
to a known value and put "conn blah/blah" like statements in the script that
calls all developer supplied scripts. Once the release is complete, it
re-sets all passwords back to what they were, and fires a compile_all script
to fix all the invalid stuff.

Michael - Yeah but the developers are always whining about something anyway 
:-) Just kidding. Yes, timing of the refresh can be an issue. We are looking

toward a staging environment. Now that will be identical to production. Then

we can execute a script that will create or modify tables and other objects,

and test the new release. If all goes well, then the same script can be used

on production. The actual test system where the developers play should have 
more modest requirements in terms of amount of data, frequency of refresh, 
etc. Anyway, this is the environment we are moving toward.
