optimal rollback segment?

Hi there,

I am trying to tune up my rollback segments. I want to set the optimal high enough to avoid dynamic extensions. I also want to create large-enough extents to support most of the transactions without wrapping. My question is: How can I know how much rollback space will need for a particular transaction? Is there any way to monitor it?

Thanx in advance.

Ed
