本次以原库全新安装后为例说明利用RMAN做异机恢复,原库和目标库路径一致,目标库仅需安装数据库软件即可,安装过程详见我的另一篇博客http://www.cnblogs.com/ilifeilong/p/7041676.html
1. 原库开启归档模式

2. 用RMAN对原库进行备份
$ mkdir /home/oracle/backupset
$ rman target / Recovery Manager: Release 11.2.0.4.0 - Production on Thu Aug 10 20:00:02 2017 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. connected to target database: USERDATA (DBID=3894924926) RMAN> run {

3. 将备份目录拷贝到目标节点相同目录
$ scp -r /home/oracle/backupset oracle@172.16.101.56:/home/oracle/
pfile.ora % .0KB/s :
arch_05sbj0sj_1_1.bak % 23MB .5MB/s :

ctl_07sbj0sl_1_1.bak % 11MB .7MB/s :
data_03sbj0se_1_1.bak % 11MB .7MB/s :
3. 目标库安装数据库软件
略过,参考 http://www.cnblogs.com/ilifeilong/p/7041676.html
4. 创建密码文件
$ scp $ORACLE_HOME/dbs/orapwuserdata oracle@sht-sgmhadoopnn-:$ORACLE_HOME/dbs/
orapwuserdata % .5KB/s :
5. 还原参数文件,启动到nomount状态
$ cat /home/oracle/backupset/pfile.ora

6. RMAN还原控制文件,并启动到mount状态
RMAN> restore controlfile from '/home/oracle/backupset/ctl_07sbj0sl_1_1.bak'; Starting restore at 2017-08-11 00:55:00
using target database control file instead of recovery catalog

Finished restore at 2017-08-11 00:55:02 RMAN> alter database mount; database mounted

7. RMAN还原与恢复数据库
RMAN> recover database; Starting recover at 2017-08-11 00:58:34

8. 以resetlogs方式打开数据库
SYS@userdata>alter database open resetlogs; Database altered.
9. 验证数据库数据
SYS@userdata>select instance_name, status from v$instance; INSTANCE_NAME STATUS
------------------------------------------------ ------------------------------------
userdata OPEN SYS@userdata>select dbid, open_mode from v$database; DBID OPEN_MODE
---------- ------------------------------------------------------------
