each plan depends on the statistical results collected by the system, but these data are not necessarily the latest. Because you may know more about the database and data content than query optimizer, you can decide a better plan than query optimizer. Using the information provided by query analyzer, you can determine whether the plan provided by query optimizer to the declarative plan is efficient. If you are sure it is not good enough, try modifying the T-

Statements that run most frequently
2.
Key statements that affect system performance
