Each database requires at least one database administrator (DBA). An Oracle Database system can be large and can have many users. Therefore, database administration is sometimes not a one-person job, but a job for a group of DBAs who share responsibility.

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

  • Installing and upgrading the Oracle Database 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 Oracle license agreements

  • 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 for technical support

Slash Networks provides training for database administrators to empower them to master working with the entire Oracle 12c suite. The topics covered include:
