51. In a system, large online transaction processing (OLTP) jobs run during the daytime that require a

large database buffer cache. In the night, the system supports batch jobs that require a higher value to be

set for the large pool. You must simultaneously configure the memory components to accommodate the

peak requirement.

What would you do to automate this configuration for the memory components with change in mode of

working?

A.Set the SGA_TARGET initialization parameter to zero.

B.Set the PRE_PAGE_SGA initialization parameter to TRUE.

C.Set the MEMORY_MAX_TARGET initialization parameter to zero.

D.Set the SGA_TARGET initialization parameter to a nonzero value.

Answer: D

SGA_TARGET 设置为非0值后，会进入assm模式，这是10G的考题了。在11G是amm用的是memory_target
