I agree with Madhu, retention is not a guarantee only a suggestion to
oracle on how much to keep around. Use the undo retention guarantee
temporarily to get your work done.

Try again with a guaranteed retention (alter tablespace <undo> retention
guarantee). This can cause some side effects, so you should probably
revert the changes after you are done. If you want to make this a
permanent setting you should size the tablespace big enough , or you may
run into "unable to extend segment" errors in the Undo tablespace.
