正确答案:CD(题库给出的答案是AD,大家要相信自己,有些答案是错的!一切以实战为依据)
一、我们先来看Oracle 11g内存架构图,来自OCP教材:
二、内存参数的一些关系:
memory_max_target、 memory_target、sga_max_size、sga_target、pga_aggregate_target
1、 sga_target=0 ,pga_aggregate_target=0 -〉完全自动管理,SGA=memory_target*60% PGA=memory_target*40%
2、 sga_target=600(最小值) ,pga_aggregate_target=200(最小值) -〉memory_target=sga_target+pga_aggregate_target
3、 sga_target=600,pga_aggregate_target=0 -〉pga_aggregate_target=memory_target-sga_target
4、 sga_target=0,pga_aggregate_target=200 -〉sga_target=memory_target-pga_aggregate_target
了解了内存的基本知识后,我们一起来解题:
答案A,不正确
根据题意,我们来实验一把:
1、设置参数
