[oracle@ora11g ~]$
A将密码文件，参数文件复制到B
[oracle@ora11g dbs]$ pwd
/u01/app/oracle/product/11.2.0/dbhome_1/dbs
[oracle@ora11g dbs]$ scp orapwORCL 192.168.56.18:/u01/app/oracle/product/11.2.0/dbhome_1/dbs

B根据参数文件创建相应目录
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/admin/ORCL/adump
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/oradata/ORCL/
[oracle@ora02 Desktop]$ mkdir -p /u01/app/oracle/fast_recovery_area/ORCL/
A将控制文件，日志文件，数据文件复制到B
[oracle@ora11g ORCL]$ scp control01.ctl 192.168.56.18:/u01/app/oracle/fast_recovery_area/ORCL/control02.ctl

B新建目录并将数据文件复制过去
[root@ora02 ~]# mkdir -p /u02/app/oracle/oradata/ORCL
[root@ora02 ~]# chown -R oracle:oinstall /u02/
[oracle@ora02 Desktop]$ cd /u01/app/oracle/oradata/ORCL/
[oracle@ora02 ORCL]$ ls
control01.ctl redo02.log sysaux01.dbf temp01.dbf users01.dbf
redo01.log redo03.log system01.dbf undotbs01.dbf
[oracle@ora02 ORCL]$ mv *.dbf /u02/app/oracle/oradata/ORCL/
B将数据库启动到mount状态
[oracle@ora02 Desktop]$ sqlplus /nolog
