RMAN--CONFIGURE Command

原创 Linux操作系统 作者:vongates 时间:2019-07-17 12:27:02 0 删除 编辑
我們在RMAN中可以通過CONFIGURE這個Command來固定一些在以前版本中要手工輸入的信息,如備份文件的存放路徑及文件名,備份文件的大小,備份策略。控制文件的備份等。下面列出在RMAN中常見的可以用于設定的信息(以及一些實例)

------------------------------------------------------------
--configure (配置RMAN的default設置)
------------------------------------
--1 顯示當前的configure
