Hi Enolvaldo,
I understand the frustration with an undo tablespace that is growing out of
control. When I see this and temp occurring and it's not due to number of
transactions using these "work areas" of Oracle efficiently, I get a little
obsessive, as it is a quick indicator when a database is working hard vs. smart
in my book.
To save some typing, I'll point you towards OracleNerd with a shameless plug of
the site, where I wrote a guest post on Undo and it might answer some questions
for you-
http://www.oraclenerd.com/2009/11/undo-brain-damage.html
It has a number of scripts that may help you out. Afterwards, you might find
that you simply want to redirect your question to finding out what is using all
the undo- is it actually correct use of the undo or is something just not right
in the database.
Hope this helps,

Hi,
I have an UNDOTBS that is growin up.
How can I do to clear it ?
I don´t need data that is there saved.
I can restart writting the UNDOTBS again.

Eriovaldo
