newbie DBA - rollback segments

I'm new to the oracle dba roll, so please be gentle.



I load several large tables every night.  My database is only about
20gB and is 24x7.  I have 10 rollback segments of 100 mB each.  I've
noticed that the I have a rather high amount of that space getting
used up (especially after I ran an adhoc UPDATE query on one of those
large tables).  How do I clear the RBS (beyond stopping and restarting
the instance)?  Is there a danger in having 75% or more utilization of
those RBS's?



Thanks,


  Mark
