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
[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.
Total System Global Area 5077495808 bytes
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.

Variable Size 3288337296 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

可以通过list backup;查看，略。
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

-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。
