Help for Task Review: Rebuilding Index (Newbie)

edited Dec 28, 2021 12:47AM in Database Administration (MOSC) 15 commentsAnswered ✓

Hello Experts!

I need help on completing my first index rebuilding task. I'm not a DB admin, but was asked to rebuild 3 indexes. I read many articles about rebuilding index and came up with below steps and have questions. I appreciate if you could leave any comments.

Thank you.


1.Temporary Tablespace size

As I read, index sorting and merging happen in Temporary Tablespace and the size of Tablespace needs to be greater than Index size(3 indexes, each has 9.5GB size). My temporary TS size is 20GB. Will it be enough to run the below 3 rebuild index statements? if not, can I add 2nd data file to Temporary TS like I am doing for other TS as below?
