注意事项：
1.源数据库与目标数据库的目录结构相同
2.目标数据库只需要安装ORACLE软件（但是参数文件中指定的目录要创建）
3.要将源数据库的数据文件，参数文件，控制文件，密码文件，归档日志统统备份
1.源数据库备份
参数文件与控制文件自动备份
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ‘/home/oracle/rmanback/level_cont_spfile_%F‘;
备份数据库及归档日志
backup incremental level 0 database format ‘/home/oracle/rmanback/level0_%d_%s_%p_%u.bak‘
plus archivelog format ‘/home/oracle/rmanback/level0arclog_%d_%s_%p_%u.bak‘ delete all input;
2.拷贝备份的文件到目标数据库的相同路径下
scp level* 192.170.100.12:/home/oracle/rmanback
3.启动数据库到nomount状态下
[oracle@server8 ~]$ rman target /

RMAN> startup nomount;

4.恢复参数文件
RMAN> restore spfile to pfile ‘/home/u01/app/oracle/product/11.2.0/db_1/dbs/initghsjdb.ora‘ from ‘/home/oracle/rmanback/level_cont_spfile_c-1442539879-20150107-00‘
2> ;
RMAN> sql ‘create spfile from pfile‘;
sql statement: create spfile from pfile
5.创建参数文件中指定的路径
mkdir -p admin/ghsjdb/adump
mkdir -p oradata/ghsjdb
mkdir -p fast_recovery_area/ghsjdb
mkdir archivelog
6.重启到nomount
RMAN> startup force nomount;
Oracle instance started
Total System Global Area 11858636800 bytes

Variable Size 7818183992 bytes
Database Buffers 3758096384 bytes
Redo Buffers 280117248 bytes
7.恢复控制文件
RMAN> restore controlfile from ‘/home/oracle/rmanback/level_cont_spfile_c-1442539879-20150107-00‘;
Starting restore at 07-JAN-15
using target database control file instead of recovery catalog

channel ORA_DISK_1: SID=1141 device type=DISK
channel ORA_DISK_1: restoring control file

output file name=/home/u01/app/oracle/oradata/ghsjdb/control01.ctl
output file name=/home/u01/app/oracle/fast_recovery_area/ghsjdb/control02.ctl
Finished restore at 07-JAN-15
8.启动数据库到mount状态
RMAN> alter database mount;
database mounted
released channel: ORA_DISK_1
9.由于目标数据库与源数据库的备份路径相同所以不需要重新在控制文件中注册
RMAN> catalog start with ‘/home/oracle/rmanback‘;
10.restore database;
RMAN> restore database;
