best practices for gathering statistics in 10g

567263Oct 17 2007 — edited Oct 18 2007

I would like to get some opinions on what is considered best practice for gathering statistics in 10g. I know that 10g has auto statistics gathering, but that doesn't seem to be very effective as I see some table stats are way out of date.

I have recommended that we have at least a weekly job that generates stats for our schema using DBMS_STATS (DBMS_STATS.gather_schema_stats). Is this the right approach to generate object stats for a schema and keep it up to date? Are index stats included in that using CASCADE?

Is it also necessary to gather system stats? I welcome any thoughts anyone might have. Thanks.
