I have a form on my application that allows the user to do the backup
of a database. This form calls 'gbak' to do this task, but i see i
need to be SYSDBA or the owner of the database to be able to run it.

But i don't want to give the sysdba password to the user, and i can't
hide it in my application, because each customer database have it's
own sysdba password.

Is there a way to do the backup with a regular user?

Thanks.
