oracle rman全备异机恢复

首先创建全备,并且将生成的备份拷贝到新的系统环境中。

RMAN> backup database format '/oracle/oradata/rman/full_backup_%U.bak' tag='full_bak' plus archivelog format

'/oracle/oradata/rman/archivelog_full_%U.bak'

1)准备系统平台,灾难前的系统平台一致。
2)设置个ORACLE_SID进入rman
export ORACLE_SID=syslogdb
[oracle@mydg1 ~]$ rman target /

connected to target database (not started)

3)将数据库启动到nomount状态
RMAN> startup nomount;

startup failed: ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/oracle/10g/dbs/initsyslogdb.ora'

RMAN>
4)使用rman 恢复spfile,默认会还原至$ORACLE_HOME/dbs目录中
#RMAN> restore spfile to '/oracle/oradata/newspfile' from
RMAN> restore spfile from '/oracle/oradata/rman/full_backup_0do6r2ph_1_1.bak';

Starting restore at 12-APR-13
using channel ORA_DISK_1

channel ORA_DISK_1: autobackup found: /oracle/oradata/rman/full_backup_0do6r2ph_1_1.bak
channel ORA_DISK_1: SPFILE restore from autobackup complete
Finished restore at 12-APR-13

5)查看spfile 内容,确认db name,以及手动创建相应的目录
这里需要手动创建的目录有
mkdir -pv /oracle/admin/syslogdb/adump
mkdir -pv /oracle/admin/syslogdb/bdump
mkdir -pv /oracle/admin/syslogdb/cdump
mkdir -pv /oracle/admin/syslogdb/udump
mkdir -pv /oracle/oradata/archive
mkdir -pv /oracle/oradata/flash_recovery_area
mkdir -pv /oracle/oradata/syslogdb

6)关闭数据库,重新进入 rman 并且启动数据库到nomount状态。
RMAN> shutdown immediate;

Oracle instance shut down

RMAN> exit

7)还原控制文件


RMAN> restore controlfile from '/oracle/oradata/rman/full_backup_0do6r2ph_1_1.bak';

Starting restore at 12-APR-13
using channel ORA_DISK_1

output filename=/oracle/oradata/syslogdb/control01.ctl
output filename=/oracle/oradata/syslogdb/control02.ctl
Finished restore at 12-APR-13

RMAN>
9)将数据库启动到mount状态加载controlfile;
RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

RMAN>
10)查看备份信息

RMAN> list backup;
如果没有列出还原时需要用到的备份片,请执行第11步
