考题 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.
