What is the _optim_peek_user_binds setting?
In any case, if the warehouse has been running for some time without
serious problem, you probably dont want to change that setting without
understanding why it was set the way it was to begin with. Of course, the
answer is likely to be that it was set that way 10 years ago in oracle 9i
and never changed it, but it is still not something to change without
testing.

I would not set it anywhere. CS = FORCE is a source of many optimizer
bugs and is only recommended in case of an emergency, where one needs to
break the glass first.

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.
