Oracle 11g
Select Name,password from sys.user$, where name in (select username from dba_users);in fact, Dba_users is a view created with related base tables such as user$.
from the dba_uses view, you can see that when a user is created as a global or external authentication, password has an encrypted value, while the password column of dba_users in 10g fully values the user$ column value of password
From for notes (Wiz)
Periodically change password periodically refresh password-copy
