What are the common Oracle DBA tasks?

Programming Language
#1

As an Oracle DBA, we must do the following duties:

  • Oracle software installation

  • Oracle database creation

  • Upgrading the database and software to the latest release levels

  • The database is started and shut off.

  • Managing the storage structures of the database

  • User management and security

  • Taking care of schema objects like tables, indexes, and views

  • Creating database backups and, if necessary, conducting database recovery

  • Monitoring the database’s health on a regular basis and taking preventative or remedial action if needed

  • Performance tracking and tweaking

In a small-to-midsize database system, a single DBA may be the only one who can handle all of these responsibilities. In big business systems, the work is sometimes split among multiple DBAs with titles such as Database Security Administrator or Database Tuning Expert, each with their particular area of expertise.
