D.Private SQL Area will be allocated in the Program Global Area (PGA) always.
E.Shared SQL Area and Private SQL Area will be allocated in the PGA or large pool.
F.The number of Private SQL Area allocations is dependent on the OPEN_CURSORS parameter.
Answer: AF
Shared SQL Area 位于sga中。实例启动就就分配,并可在运行过程中动态或手动调整。
Private SQL Area 当使用共享服务器时位于sga中,当使用专用服务器时位于pga中
Private SQL Area 的个数依赖于参数 OPEN_CURSORS 的设置
可以以下语句观察该参数及其它类似参数的设置及应用情况
