Hi Larry
SYS schema don't need be analyzed, using tom kyte's word "it's magical" and must not be analyzed
if you got statistics in sys, you can ruin it's performance. sys schema don't have to be touched, this means don't create user tables in sys, etc.

Subject: SHOULD WE ANALYZE 9.2 SYS tables?

I had a question about a problem with 9.2 V$ views where a RULE hint helped V$LOCK tremendously.

Someone suggested Analyzing the SYS tables. IS everyone doing that now or is there considerable reticence? I didn't get a much current information when I searched the FAQ or Google

Has anyone experienced a downside?

Is anyone doing some of the tables but not all?

Thanks
Larry Wolfson
