原来的数据库服务器使用rman进行全库的备份，然后再异地的服务器上恢复一模一样的数据库 1.1 原服务器备份数据库 第一步，查看数据库的实例名和DBID connected to target database: DB3 (DBID=2060124769, not open) 第二步，进行全备份 backup AS COMPRESSED BACKUPSET database include current controlfile format '/orabak/db_%d_%T_%s' plus archivelog format '/orabak/arch_%d_%T_%s' ; 第三步，查看数据库文件的位置： /home/oracle/oradata/db3/ 第四步，将备份文件arch_DB3_20140910_8和 db_ DB3_20140910_7复制异机上/home/oracle/orabak 1.2 目标服务器上创建数据库 第一步，创建实例名相同（db3）,数据库文件的位置相同（/home/oracle/oradata/db3/）的数据库。 第二步，关闭实例，启动到nomount状态。Sql>startup nomount; 第三步，设置dbid和原数据库dbid相同 rman target/ Recovery Manager: Release 10.2.0.5.0 - Production on Thu Sep 11 19:53:50 2014 Copyright (c) 1982, 2007, Oracle.
