One of the biggest responsibilities of a DBA is to ensure that the Oracle database is tuned properly. The Oracle RDBMS is highly tunable and allows the database to be monitored and adjusted to increase its performance. One should do performance tuning for the following reasons:
- The speed of computing might be wasting valuable human time (users waiting for response);
- Enable your system to keep-up with the speed business is conducted; and
- Optimize hardware usage to save money (companies are spending millions on hardware).
