Why not create a new undotbs, change parameter to use new undotbs, drop old
undotbs?

Subject: how to shrink undo tablespace on 10GR2?
We have 10GR2 on Linux server. I found one database "undo" tablespace has been
extend to 32 GB size. I used 'dba_free_space" to check and found this data
file actually is empty. I tried to "resize" it back to small size but I can
only resize it to 28GB. I knew this may be cause by "high water mark".
Does there has way to shrink it to small?
Thanks.
