online index rebuilds

Any other differences besides: 1) does not lock the table; 2) does a full table scan instead of full index scan; ?

Had read the article, but I am interested as to why Oracle is doing a full table scan instead of full index scan for online index rebuilds.

Thanks Tanel,
Is there any reason why Oracle does full table scans for online rebuilds and not for offline.

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 transaction s going on while you are rebuilding the index onl ine, you need additional space in target tablespace.
