DBA password recovery / DBA password recovery from OS / any way to recovery the DBA password :P

Hi there,

Is there any way to recovery password for sysdba in Teradata from filesystem?

As far as I know, there is option like this in Oracle where Oracle user can enter the database as sysadmin without password. 

Is there a similar method in Teradata?

Or is there ANY way to recover the DBA password or otheres? 

Would like to check it on my virtual test machina'e.

Is there an option to turn this function off as a security alert?

Regards
