Common Oracle DBA Tasks

As an Oracle DBA, you can expect to be involved in the following tasks:
■ Installing Oracle software
■ Creating Oracle databases
■ Performing upgrades of the database  and software to new release levels
■ Starting up and shutting down the database
■ Managing the storage structures of the database
■ Managing users and security
■ Managing database objects, such as tables, indexes, and views
■ Backing up the database and performing recovery operations when necessary
■ Monitoring the state of the database and taking preventive or corrective action as required
■ Monitoring and tuning database performance
■ Diagnosing and reporting critical errors to Oracle Support Services

In a small to medium-sized database envi ronment, you might be the sole person
performing these tasks. In large, enterprise environments, the job is often divided
among several DBAs, each of whom has a sp ecialty, such as database security or
database tuning
