Walter, this is actually a bug. It's supposedly fixed in 9i though I haven't tried it. Anybody? Do you still see a performance hit when you delete the statistics from the SYS objects?
Regards, Mike Hately -----Original Message----- Sent: 25 April 2002 15:33 To: Multiple recipients of list ORACLE-L If you're not supposed to analyze SYS and SYSTEM then can anyone explain why the DBMS_STATS.GATHER_DATABASE_STATS procedure does? We have run into scenarios where the data dictionary becomes almost unusable until SYS gets analyzed again via this procedure. I.e. can't describe v$ views, selects against v$ views take forever to return results, etc. The obvious solution is to not use this particular procedure but it still begs the question WHY doesn't it exclude SYS and SYSTEM? Are there any reasons why you would want to analyze these schemas?
