 NAME                                                           VARCHAR2(32)

 BYTES                                                          NUMBER

 RESIZEABLE                                                     VARCHAR2(3)

 RESIZEABLE    为YES的在AMM或者ASMM的时候就会自动调整池的大小,为NO的就只能手动调整。

图中sga_target设置有值,故是ASMM管理。
