系统：linux 6.4，
数据库：oracle 11g r2
A主机：安装oracle 11g r2数据库
B主机：只安装oracle 11g r2软件
第一步，运行下面rman命令备份数据库
run{
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/u01/app/dbback/config_%F';
allocate channel c1 type disk format '/u01/app/dbback/full_%U';
backup database tag 'full_gpodb_data' FILESPERSET 10 PLUS ARCHIVELOG FILESPERSET 20 DELETE ALL INPUT;
release channel c1;
}

第二步，创建pfile参数文件
[oracle@bogon dbs]$ sqlplus "/as sysdba"
SQL*Plus: Release 11.2.0.1.0 Production on Sat Oct 26 05:52:14 2013

Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SQL> create pfile from spfile;
File created.
第三步，利用scp命令将备份文件，pfile参数文件传输到B主机
备份文件的目标在/u01/app/dbback，首先在B主机创建dbback目录
[oracle@bogon app]$ mkdir dbback
传输pfile文件（这这里将/u01/app/oracle/product/11.2.1/db_1/dbs目录下的文件全部传输到了B主机）
[oracle@bogon dbs]$ scp * 192.168.1.103:/u01/app/oracle/product/11.2.1/db_1/dbs
The authenticity of host '192.168.1.103 (192.168.1.103)' can't be established.
RSA key fingerprint is aa:25:3b:48:55:b9:e9:f5:dd:60:2d:55:b5:93:af:db.
Are you sure you want to continue connecting (yes/no)? yes

[oracle@bogon dbback]$ cd ~
第四步，登陆B主机，创建和A主机相对应的文件夹
我主机的oracle 文件安装在/u01/app/oracle
[oracle@bogon app]$ cd oracle
[oracle@bogon oracle]$ ls ---------------和A主机对应缺少了diag flash_recovery_area oradata admin cfgtoollogs 文件夹
checkpoints product
[oracle@bogon oracle]$
[oracle@bogon oracle]$ mkdir diag flash_recovery_area oradata admin cfgtoollogs --------创建文件夹
[oracle@bogon oracle]$ cd oradata
[oracle@bogon oradata]$ ls
[oracle@bogon oradata]$ mkdir db
[oracle@bogon oradata]$ ls
db
[oracle@bogon oracle]$ cd cfgtoollogs
[oracle@bogon cfgtoollogs]$ ls
[oracle@bogon cfgtoollogs]$ mkdir dbca emca netca
[oracle@bogon cfgtoollogs]$
[oracle@bogon admin]$ mkdir db
[oracle@bogon admin]$ cd db
[oracle@bogon db]$ ls
[oracle@bogon db]$ mkdir adump dpdump pfile
[oracle@bogon db]$
[oracle@bogon oracle]$ cd flash_recovery_area
[oracle@bogon flash_recovery_area]$ ls
[oracle@bogon flash_recovery_area]$ mkdir db
[oracle@bogon app]$ pwd
/u01/app
[oracle@bogon archiv]$ mkdir archiv
第五步，启动B主机数据库到nomount状态
oracle@bogon ~]$ export ORACLE_SID=db
[oracle@bogon ~]$
[oracle@bogon ~]$ sqlplus "/as sysdba"
