System maintenance and the use of some Vantage utilities may require operating system-level (OS-level) access. Teradata Vantage runs as a system-generated, OS-level user.
For information on how to execute an OS-level logon to run a utility, see Teradata Vantage™ - Database Utilities, B035-1102.
For information on the default Teradata Vantage OS-level users, see Controlling Access to the Operating System.
