if your table is very big , then use partition table will be a must.
then you can use exchange  partition to minimize the undo with it.
delete from a big table is a bad idea.

if you have a undo tablespace that extended beyond your control. then
create a new undo tablespace . and change the undo tablespace online
may be a better solution than to wait the SMON to clean then undo

within my technical scope. if there were no other transaction request
the undo from the undo tablespace , oracle will not release this undo
