Re: UNDO poll - was undo segments vs. rbs

After playing around with the retention time we significantly reduced the 
amount of  undo we were using compared to RBS with autoextend off.

I'd be interested in a quick poll.

Your case is the first time I've heard of undo space
being less than rollback space. Every other comment
I've heard has been along the lines of
why has my 1GB rbs t/s grown to 12GB when
I switched to undo t/s.

So - out of three options:
Undo much bigger
Undo much smaller
No significant change noticed

Would people like to contribute.

I've changed the subject heading to isolate the poll.

Paula,

In our warehouse, we had a RBS tablespace of 25Gig. After conversion to
Undo, the Undo Tablespace was reduced to 6 Gig - and I personally think it
could be much smaller.
