Re: Undo x Rollback Segments in 9i

have u read the docs on the differences yet?

there is a bit to read about(as i'm going thru it all for a potential presentation on automatic undo management).

i think the verdict has not been decided yet as to whether its good or not as its too new for alot of people.
