Subject Re: transaction behaviour

I wouldn't expect that behaviour at all.  I've been using DB2 and haven't seen 
that happen.  What leads you to believe that data isn't being persisted at the 
end of the transaction?

So, to restate what you said so I understand:

1. Using MySQL it appears that data is persisted correctly.

2. Using the Oracle Driver you see some caching occurring?

Can you provide the plan you are using that describes the database connections?
