DBA SECURITY AND PRIVILEGES

• To perform the administrative tasks of an Oracle
  Database DBA, you need specific privileges within
  the database and possibly in the operating system
  of the server on which the database runs. Access
  to a database administrator's account should be
  tightly controlled.

6
DBA AUTHENTICATION

• As a DBA, you often perform special operations
  such as shutting down or starting up a database.
  Because only a DBA should perform these
  operations, the database administrator usernames
  require a secure authentication scheme.

7
SERVER MANAGEABILITY

• Oracle Database is a sophisticated self-managing
  database that automatically monitors, adapts, and
  repairs itself. It automates routine DBA tasks
  and reduces the complexity of space, memory, and
  resource administration. Several advisors are
  provided to help you analyze specific objects.
  The advisors report on a variety of aspects of
  the object and describe recommended actions.
