Database Administrators

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
