Hello:

I've heard it from other DBAs - that a DBA can carry by exp/imp method, or other methods in Oracle so that all passwords of a database's users can be copied to another database.   It is not the 'dba_users' view, not the 'passwords' column in 'dba_users' which is hashvalue only.

I'm talking this because it is important components related to DB-App integration.  For example, if incident happen and application lost all its username/passwords, flush the info away, how do you recover it?

Has anyone did similar things before? I assume it is a hidden system table has this information.

Howdy, Stranger!
