Hi All,
I am recreating all rollback segments for Oracle 8.0.6.3/NT-SP2. Currently, I have 20 PUBLIC rollback segments without OPTIMAL values and their size are different. I want to create them using storage as

storage (
initial 10M
Next 10M
Minextents 10
optimal 100M
)

Right now I have 3 G (1G x 3 datafile for RBS) for rollback. If I want to specify maxextents in my storage settings above, how to calculate it? 20 rollback * 100 M = 2 G. IF I don't specify maxextent, what kind of problem I may run into?

Please advise!
Thanks
