Each database requires at least one database administrator (DBA) to administer it. Because an Oracle database system can be large and can have many users, often this is not a one person job. In such cases, there is a group of DBAs who share responsibility.

A database administrator's responsibilities can include the following tasks:

Installing and upgrading the Oracle server and application tools
Allocating system storage and planning future storage requirements for the database system
Creating primary database storage structures (tablespaces) after application developers have designed an application
Creating primary objects (tables, views, indexes) once application developers have designed an application
Modifying the database structure, as necessary, from information given by application developers
Enrolling users and maintaining system security
Ensuring compliance with your Oracle license agreement
Controlling and monitoring user access to the database
Monitoring and optimizing the performance of the database
Planning for backup and recovery of database information
Maintaining archived data on tape
Backing up and restoring the database
Contacting Oracle Corporation for technical support

Oracle DBA Responsibilities

(1) Creates and maintains all databases required for development, testing,
education and production usage.

(2) Performs the capacity planning required to create and maintain the
databases. The DBA works closely with system administration staff because
computers often have applications or tools on them in addition to the Oracle
Databases.

(3) Performs ongoing tuning of the database instances.

(4) Install new versions of the Oracle RDBMS and its tools and any other tools
that access the Oracle database.

(5) Plans and implements backup and recovery of the Oracle database.

(6) Controls migrations of programs, database changes, reference data changes
and menu changes through the development life cycle.
