Well, my name is not Tanel, but I'll jump in here and point you to MetaLink Doc ID 272762.1. -Mark -- Mark J. Bobak Senior Oracle Architect ProQuest Information & Learning "There are 10 types of people in the world: Those who understand binary, and those who don't." ________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Joseph Amalraj Sent: Tuesday, January 24, 2006 9:59 AM To: ORACLE-L Subject: Re: ORA-01652: unable to extend temp segment Thanks Tanel, Is there any reason why Oracle does full table scans for online rebuilds and not for offline. Regards Joseph Amalraj Tanel Põder <tanel.poder.003@xxxxxxx> wrote: Online rebuilds don't use existing index for creating new. They do full table scan on the table. However, in both cases, old index segment is kept until new one is ready to use and switch to it is done. Also the journal IOTs used for online rebuilds are stored in the target tablespace, so if you've got lots of transactions going on while you are rebuilding the index onl ine, you need additional space in target tablespace.
