注意事项：1 此处实验环境为同平台，同字节序，同版本，源机器和目标机器相同的目录结构。2 目标机器只需要安装Oracle数据库软件即可。3 第一次利用备份恢复测试环境，之后从源机器拷贝备份到目标机器并在控制文件中注册，再见行恢复测试。 一 拷贝参数文件备份、控制文件备份、数据文件备份、以及归档备份到新主机上 1 rman 连接到源数据库 [oracle@oracle dbs]$ rman target /Recovery Manager: Release 10.2.0.1.0 - PRoduction on Tue Dec 11 19:02:05 2012Copyright (c) 1982, 2005, Oracle.
