When Vantage is first installed on a server, user DBC is created. User DBC owns (with some exceptions):
- All free space on the system
- All databases and users created after installation
The database administrator manages user DBC and assigns space from user DBC to all other objects (or database and users).
To protect the security of system tables within Vantage, the database administrator typically creates user System Administrator from user DBC. The usual procedure is to assign all database disk space that system tables do not require to user System Administrator.
The database administrator then uses user System Administrator as a resource from which to allocate space to other databases and users of the system.
For information on how to create databases and users, see Teradata Vantageā¢ - Database Administration, B035-1093.
