RE: Rollback seg for big job

Prasad:

As far as I know (and listers please correct me if I'm wrong) you can't single out the rollback segment you are using for that big transaction EXCLUSIVELY. In other words, since the rbs is still online and available, there is still the potential that another transaction could use that rbs as well. However, if you're running it at night, wouldn't your activity level be lower and thus the odds of getting another transaction in the same rbs be much lower as well?

Just my 2 cents.
