Re: Trying to drop old undo tablespace that needs recovery

Alexander Gorbachev


Hi Chris,

I had once a problem with system transactions (in SYSTEM RBS) that got
stuck. SMON was core dumping all the time and complaining. The
database was working like that for few months (test system but
important one) excluding certain functionality (this is where
dictionary was affected I guess).
Do you think that can be rocovered as well? In fact, I still have it -
just finished migration to a new database and about to give away this
old "broken" DB. Would be interesting to try to recover it now.
