Thanks everybody,

Is there any specific reason for setting the optimal size at avg(hwmsize) . My optimal value comes out to be 20 MB. This means that my initial and next should be 10 MB each as opposed to the initial=next=56KB.

what is the best approach to do this as it is not allowed to change the initial extent once it is set. Should I create 2 more rollback segments with the above values and bring them online and finally drop the older ones.

Please suggest.

Thanks
Anurag
