checkdb

I am turning on DBCC CHECKDB in our OLTP environment (SQL 2005,2008). System overhead is a very visible thing on our serversso I want them to be as efficient as it makes sense for them to be. HENCE - I want to turn on the NOINDEX option, an option I've never used before. My thoughts are these: if there is a problem with an index that is detected outside the integrity check, that I can just rebuild the index. Also the duration of the integrity checks will be drastically reduced, and the nastier corruption will be detected.

What is the flaw in my plan?

Thanks, Deb
