Which statement about Automatic Memory Management with Oracle 11g is true?()
A

 You cannot specify MEMORY_TARGET if you explicitly specify SGA_TARGET or  PGA_AGGREGATE_ TARGET values that are greater than zero in your parameter file.

B

 Oracle can reallocate memory between the SGA and PGA automatically as needed.

C

 To use Automatic Memory Management, you must explicitly set both the MEMORY_TARGET and MEMORY_MAX_TARGET parameters in your parameter file.

D

 You can set the MEMORY_TARGET parameter to a maximum value of the current SGA size plus the current PGA size.

第1题:

You specify a nonzero value for the MEMORY_TARGET initialization parameter, but do not set the PGA_AGGREGATE_TARGET or the SGA_TARGET parameters. You restart your database instance.Which statement about the result is true?()

A. The database instance starts, and Oracle sets the default value of SGA_TARGET to the same value as SGA_MAX_SIZE

B. The database instance starts, and Oracle automatically tunes memory and allocates 60 percent to the SGA and 40 percent to the PGA

C. The database instance starts, but Automatic Memory Management is disabled

D. The database instance will not start because you did not specify the PGA_AGGREGATE_TARGET or SGA_TARGET parameter


参考答案:B

第2题:

Which statements about the MEMORY_TARGET initialization parameter are true?() (Choose all that apply.)

A. MEMORY_TARGET can be increased up to the value of MEMORY_MAX_TARGET, if MEMORY_MAX_TARGET is set to a value greater than zero

B. MEMORY_MAX_TARGET defaults to a value of zero if MEMORY_TARGET is not set

C. MEMORY_TARGET represents the total amount of memory that can be allocated to SGA and PGA memory structures.

D. MEMORY_TARGET is static and cannot be modified without shutting down the instance


参考答案:A

第3题:

Examine the parameter setting in your database:Which statement is correct about the database?()

A. Automatic memory management is disabled because PGA_AGGREGATE_TARGET and SGA_TARGET are not set

B. The instance is started but the database will not be opened until PGA_AGGREGATE_TARGET and SGA_TARGET are set

C. The database is opened but users cannot perform transactions until PGA_AGGREGATE_TARGET and SGA_TARGET are set

D. Automatic memory management is enabled and, as per policy, 60% of the memory for System Global Area (SGA) and 40% of the memory for Program Global Area (PGA) will be distributed at startup
