IMPORTANT: I'm playing with backup of customer's database on my machine. Never try to do anything like this quickly on production server without trying it in sandbox first. Use DB backups.

UPDATE: finally proved myself with your help that it's possible when playing with small databases. So final answer is YES.

Always - NO, sometimes you must fail fast.

Later I will check FAQ how to correctly "close a case" here.

I have 1 SQL Server 2008 and 1 Oracle database (did not check which version it is).

So, it possible at all with ArcGIS 10.0 to take a simple database and upgrade to geodatabase?

Update: Replaced our code with strategy OLEDb using best practices in the world.

Update: SET ARITHABORT OFF did not work. Played with empty new database, once set it ON and then OFF. And in both cases result was OK. This means ARITHABORT doesn't matter. That's incorrect error message. Too many if-s in code.
