Yes. When you enable automatic undo management you leave all of that to
the database engine.

Subject: question regarding automatic undo
Two identical databases.
database 1 has 10 undo online and 2 offline
database 2 has 10 undo online and 23 offline
Why does the second have more offline undo segments. Does Oracle
automatically create them if needed and when no longer needed offline
it??
