1. not much experience
2. yes it will, but in 8i the rate at which the stats were updated in the DD was *slow*, in 9i it is on demand or 5 minutes I think.

Subject: Question On Statistics Gathering
Hi All,
Currently we have a very large database ( 8.1.7.4 ) on Tru64 that is having query optimization problems. Lacking good, up-to-date statistics is the main cause of it. Because of the size and availability window we can't afford to analyze the whole schema. Now 8i has
a new feature that only gathers stats when stale. You have to set table to monitoring mode first.
I am intrigued by this new feature and am reading up on it and have 2 questions:
1. How reliable and bug-free is this feature?
2. We do a lot of sqlldr direct path, which bypasses table insert. Will this feature catch the rows inserted that way?
TIA
Dennis
