The objectives of tuning are:
- Minimizing response time
- Increasing throughput (Doing more using less resources)
- Increasing load capabilities
- Decreasing recovery time
Business
requirements affect tuning goals. Performance may be limited by safety
concerns, as in the “Decreasing recovery time” goal.
In a
business environment where down time may be measured in hundreds or thousands
of dollars per minute, the overhead of protecting the instance from failure and
reducing recovery time is more important than the user response time.
