Hi,
I would not set cs=forced in a DWH. These a logrunning queries and the plans
should be as good as possible.
Parse time will normally be a lesser concern.
Just to give an example: Bind varaibles for a partition key should inhibit from
partion stats being used on parsing.
Regards
Lothar

Betreff : cursor_sharing setting
All,
I logged into a reasonably sized data warehouse system which I just
inherited. Apart from several surprises, I also see cursor sharing set to
Force. To me it looks very counter intuitive to set CS to force in a DW. I
would think you would want the cursors to be parsed for almost all the
executions. ver12 and uses star schema. Thoughts?
CP.
