篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了oracle rac rman 备份怎么恢复到另外的rac相关的知识，希望对你有一定的参考价值。

参考技术A rac rman 备份和恢复和单实例的备份和恢复稍有不同,ORACLE RAC主要是有多个实例,但是千万不要把多实例和多数据库搞混淆,在RAC中通常情况下一台服务器

Oracle 11g R2 RAC数据库备份通过RMAN恢复到单实例数据库实现

下面是我的一次从Oracle 11g R2 RAC到单实例间通过RMAN恢复备份集的过程，记录在此。

有些人以此方法作为RMAN备份有效性校验，当然我不反对这个说法，但我也相信RMAN提供的备份有效性校验方法，参考我整理的博文：《Oracle RMAN(Recovery Manager) – 安全性与监控》

操作环境：

• Source DB: 2-Node Oracle Database 11g R2 RAC On Linux(11.2.0.1 with ASM)

• Target DB: Single Instance Database 11g R2 On Linux(11.2.0.1 with FileSystem)

目标端数据库环境介绍：

[root@luocs ~]# hostname

罗成网·新闻资讯服务北大门

[root@luocs ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/cciss/c0d0p1 388G 9.1G 359G 3% /

/dev/cciss/c0d0p3 421G 2.6G 397G 1% /data

tmpfs 5.9G 0 5.9G 0% /dev/shm

– 目标端磁盘空间需要充足，至少要比源端所有数据文件大小还大。

源端与目标端环境已准备好，下面开始进入操作。

1.将源端的一个FULL BACKUPSET拷贝到目标端

我在目标端创建/data/bak目录，将备份文件放于这里

[root@luocs ~]# mkdir /data/bak

[root@luocs ~]# chown -R oracle.oinstall /data/bak/

异机拷贝使用scp或者ftp方式都可以，略。

我这里备份文件已打包，所以在目标端进行解压

[oracle@luocs bak]$ tar zxvf fulldb20121211.tgz

[oracle@luocs bak]$ tar zxvf ArchFile20121211.tgz

2.从备份中恢复参数文件

我的一贯作风，在动现场之前保留一份源文件

[oracle@luocs dbs]$ pwd

/u01/app/oracle/product/11.2.0/dbhome_1/dbs

[oracle@luocs dbs]$ cp -p spfilehkrt.ora spfilehkrt.ora.bak

将数据库启动到nomount状态

SQL> startup nomount

ORACLE instance started.

Fixed Size 2212976 bytes

Variable Size 3288337296 bytes

Database Buffers 1744830464 bytes

Redo Buffers 42115072 bytes

通过RMAN工具还原出参数文件，还原出初始化参数文件

RMAN> restore spfile to pfile \'/u01/app/oracle/product/11.2.0/dbhome_1/dbs/inithkrt.ora\' from \'/data/bak/full_HKRT_1mnsi77q_1_1\';

Starting restore at 12-DEC-2012 00:21:03

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=1 device type=DISK

channel ORA_DISK_1: restoring spfile from AUTOBACKUP /data/bak/full_HKRT_1mnsi77q_1_1

channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete

Finished restore at 12-DEC-2012 00:21:05

3.编辑初始化参数文件，相应地创建所需目录

[oracle@luocs dbs]$ cp -p inithkrt.ora inithkrt.ora.bak

我们恢复过来的参数文件是RAC的，所以我们要改成符合单实例数据库

[oracle@luocs dbs]$ cat inithkrt.ora

创建相应的目录

[root@luocs ~]# mkdir /u01/arch

[root@luocs ~]# chown oracle.oinstall /u01/arch

-- 存放归档日志文件

[root@luocs ~]# mkdir /u01/app/oracle/admin/hkrt/adump -p

[root@luocs ~]# chown -R oracle.oinstall /u01/app/oracle/admin/hkrt

-- 存放审计跟踪文件

[root@luocs ~]# mkdir /u01/app/oracle/oradata/hkrt/

[root@luocs ~]# chown oracle.oinstall /u01/app/oracle/oradata/hkrt/

-- 存放数据文件

4.通过编辑好的初始化参数重启数据库到NOMOUNT

SQL> shutdown immediate

ORA-01507: database not mounted

ORACLE instance shut down.

SQL> create spfile from pfile;

File created.

SQL> startup nomount

ORACLE instance started.

Total System Global Area 5077495808 bytes

Variable Size 3288337296 bytes

Database Buffers 1744830464 bytes

Redo Buffers 42115072 bytes

5.从备份集还原控制文件

我们从备份集里还原出控制文件

RMAN> restore controlfile from \'/data/bak/full_HKRT_1lnsi77o_1_1\';

Starting restore at 12-DEC-2012 00:35:22

using channel ORA_DISK_1

channel ORA_DISK_1: restoring control file

channel ORA_DISK_1: restore complete, elapsed time: 00:00:01

output file name=/u01/app/oracle/oradata/hkrt/control01.dbf

output file name=/u01/app/oracle/oradata/hkrt/control02.dbf

Finished restore at 12-DEC-2012 00:35:23

将数据库启动到MOUNT状态

RMAN> mount database;

database mounted

released channel: ORA_DISK_1

6.将备份集注册进控制文件里

RMAN> catalog start with \'/data/bak/\';

searching for all files that match the pattern /data/bak/

List of Files Unknown to the Database

=====================================

File Name: /data/bak/full_HKRT_1mnsi77q_1_1

7.确认数据文件、联机日志文件、临时文件路径

SQL> set pagesize 9999

SQL> col NAME for a65

SQL> select file#,name from v$datafile;

8.通过RMAN重命名数据文件和临时文件，进行还原

最后聊一下从full backupset里如何找出参数文件和控制文件备份集的方法

[oracle@luocs bak]$ ls -l

-rw-r----- 1 oracle oinstall 18972672 Dec 11 01:01 full_HKRT_1lnsi77o_1_1

-rw-r----- 1 oracle oinstall 98304 Dec 11 01:01 full_HKRT_1mnsi77q_1_1

这里以full开头的就是数据文件+参数文件+控制文件的备份集，分辨方法非常简单，看大小即可。

一般最小的为参数文件备份集，大的是数据文件备份集。

如果你难以确定，直接到RMAN里尝试下就可以。
