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??
