As a production DBA, my first thought would : How do I fix it before Oracle give me a solution after 3+ weeks(typical response time from oracle).
And the answer I think is: revert back to old rollback segment. Say, online 30 rollback segment with proper size and keep then online. The old rollback segment works best for big/busy/frequent change database, and the AUM works best for small/stable database, I think.

That's it. Received on Fri Dec 30 2005 - 15:05:22 CST
