問題文
Users report that the order entry application became slower this week. The administrator has several ideas about what to change. Which approach follows the documented tuning method?
選択肢
- Measure where the time is actually spent and compare the result against a period of acceptable performance and then change the one thing pointed at by the measurement.
- Raise the memory parameters and the number of parallel servers at the same time and later watch the response time of the application over the next few days.
- Rebuild the indexes of the largest tables and gather statistics on every schema and then ask the users whether the application feels faster than before.
- Move the busiest tables into a new tablespace on faster storage and then compare the number of physical reads before the change and later.
