Oracle11g异机恢复

Oracle 11g 异机恢复参考文档

本次以原库全新安装后为例说明利用RMAN做异机恢复,原库和目标库路径一致,目标库仅需安装数据库软件即可,安装过程详见我的另一篇博客http://www.cnblogs.com/ilifeilong/p/7041676.html

1. 原库开启归档模式
SYS@userdata>archive log list;
Database log mode 　No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1
Current log sequence 3

SYS@userdata>shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

SYS@userdata>startup mount;
ORACLE instance started.

Total System Global Area 1837244416 bytes
Fixed Size 2254224 bytes
Variable Size 637536880 bytes
Database Buffers 1191182336 bytes
Redo Buffers 6270976 bytes
Database mounted.

SYS@userdata>alter database archivelog;

Database altered.

SYS@userdata>alter database open;

Database altered.

SYS@userdata>archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 1
Next log sequence to archive 3
Current log sequence 3

2. 用RMAN对原库进行备份

$ mkdir /home/oracle/backupset
$ rman target /

SYS@userdata>create pfile=’/home/oracle/backupset/pfile.ora’ from spfile;

3. 将备份目录拷贝到目标节点相同目录

$ scp -r /home/oracle/backupset oracle@172.16.101.56:/home/oracle/
pfile.ora 100% 1018 1.0KB/s 00:00
arch_05sbj0sj_1_1.bak 100% 23MB 22.5MB/s 00:00

data_03sbj0se_1_1.bak 100% 11MB 10.7MB/s 00:00

3. 目标库安装数据库软件
略过,参考 http://www.cnblogs.com/ilifeilong/p/7041676.html
4. 创建密码文件
$ scp $ORACLE_HOME/dbs/orapwuserdata oracle@sht-sgmhadoopnn-02:$ORACLE_HOME/dbs/
orapwuserdata 100% 1536 1.5KB/s 00:00
5. 还原参数文件,启动到nomount状态

$ cat /home/oracle/backupset/pfile.ora

6. RMAN还原控制文件,并启动到mount状态

RMAN> restore controlfile from ‘/home/oracle/backupset/ctl_07sbj0sl_1_1.bak’;

Starting restore at 2017-08-11 00:55:00
using target database control file instead of recovery catalog

Finished restore at 2017-08-11 00:55:02

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

7. RMAN还原与恢复数据库

RMAN> recover database;

Starting recover at 2017-08-11 00:58:34

8. 以resetlogs方式打开数据库
SYS@userdata>alter database open resetlogs;

Database altered.
9. 验证数据库数据

SYS@userdata>select instance_name, status from v$instance;
