I HAVE to reply to this ( and you know it and maybe even counted on it :-) ). The way I see it, you have two choices:
a) Do the daily analyze and then deal with the problems it causes b) NOT do the daily analyze and then deal with the problems IT causes
hi, all, We have a 3rd party application running on our database, and the vendor asked us to run daily analyze , for those tables with dba_segments/dba_tables shows 5%+ difference for blocks. And we consistenly run into problem with the SQL plan changed, as sometimes analyze caused the plan goes bad.
I want to stop the anlyze, as our current plan is ok, which can meet our SLA requirement. And our database is already 5TB+, I think if we stop analyze, and the CBO statistics does not get updated, the plan should be ok and stable.
How about your opinion? We are still running oracle 8174 on solaris8.
