Which twoinitialization parameters would you set to enableAutomatic Shared Memory Management? (Choose two.)
A. setSHARED_POOL_SIZE to zero
B. setSTATISTICS_LEVEL to BASIC
C. set SGA_TARGETto a non-zero value
D. setDB_CACHE_SIZE to a non-zero value
E. set STATISTICS_LEVELto TYPICAL or ALL
Answer: CE
唐老师,这一题答案为何是CE,而不是AC 统计信息收集的参数跟自动内存管理ASMM有什么关系?
另外一个例子,如果说已经指定了memory_target=1G;同时PGA,SGA_TARGET都为0,那么可以说启用了AMM 可是如果此时指定SGA_target=600M,是不是就意味着不是AMM了,而变成了ASMM? 还是说此时还可以称为AMM,只是SGA最小分配600M,其余还有400M内存,依然是自动分配,也算AMM?
