Re: EM Grid Control-Sql Advisor

sql tuning adv never changes the SQL, it usually gives 3 types of recommendations:

1. add indexes
2. gather stats
3. profile: this is a bunch of hints giving the CBO more accurate stats about the SQL (e.g. cardinalities of some columns, ....)

It may give advices of type 1 and 3, and you can choose to implement either or all of the advices that it gives.
