Home -> Community -> Mailing Lists -> Oracle-L -> RE: How long are statistics good for
Anand,
Just curious : Is there some test or other observation that you can share with the list about dbms_stats using 10% as a boundary for staleness?
John Kanagaraj
Which version of Oracle are you using. In 8i you can set 'monitoring on' for the tables and use dbms_stats to analyze stale. (Though, I am getting error while using dbms_stats for the partitioned tables. So I have made a home made version to analyze stale). As per my calculations, package dbms_stats considers statistics stale if all DMLs affect more than 10% of number of rows.
