No reason not to set autoextend on temp and undo - just make sure you have a reasonable maxsize along with it - as you should have with ALL autoextend tablespaces. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Joel.Patterson@xxxxxxxxxxx I agree. I was also thinking that UNDO would be analogous to TEMP. ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Smith, Steven K - MSHA I don't see the big downside of having autoextend on (except for temp tablespaces - those things can become a monster with a bad piece of code).
