2.Which three statements are true about pfiles, spfiles or both?

  A) All spfile parameters can be modified successfully with the scope=both clause.

  B) A spfile can be created by an idle instance.

  C) spfiles and pfiles may both be edited with an O/S editing utility.

  D) Some spfile parameters can be modified successfully with the scope=memory clause.

  E) A pfile can be created by an idle instance.

  F) All spfile parameters can be modified successfully with the scope=memory clause.

  (解析:spfile 和 pfile 可以互相转换,而且不需要实例启动,参数分为静态参数和动态参数,只有动态参数才能够马上修改生效。备注来自ocp3群:1015267481)
