恢复测试,模拟数据库硬盘损坏数据丢失。

1、数据库全备份,

2、备份数据文件、控制文件、spfile、口令文件

3、删除数据库(用dbca删除),只留oracle程序。

4、启动数据库实例

HB130000 oracle$rman target / catalog rman/rman@omsora9

Recovery Manager: Release 9.2.0.1.0 - 64bit Production

Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.

connected to target database (not started)

connected to recovery catalog database

RMAN> startup nomount

startup failed: ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/oracle/oracle/app/oracle/product/9.2.

0.1/dbs/inithb130000.ora'

trying to start the Oracle instance without parameter files ...

Fixed Size 741864 bytes

Variable Size 104857600 bytes

Database Buffers 50331648 bytes

Redo Buffers 798720 bytes

5、查询原数据库dbid,恢复spfile

RMAN> list incarnation;查询原数据库的dbid。

List of Database Incarnations

DB Key Inc Key DB Name DB ID CUR Reset SCN Reset Time

------- ------- -------- ---------------- --- ---------- ----------

15936 131731 HB130000 2380174037 YES 23440815 25-AUG-05

RMAN> set dbid=2380174037; 设置dbid。

executing command: SET DBID

RMAN> restore spfile;

Starting restore at 13-SEP-05

using channel ORA_DISK_1

using channel ORA_DISK_2

using channel ORA_DISK_3

using channel ORA_DISK_4

channel ORA_DISK_1: starting datafile backupset restore

channel ORA_DISK_1: restoring SPFILE

output filename=/oracle/oracle/app/oracle/product/9.2.0.1/dbs/spfilehb130000.ora

channel ORA_DISK_1: restored backup piece 1

piece handle=/oradata/rmanbackup/hb130000_ctl_c-2380174037-20050913-00.bak tag=n

ull params=NULL

channel ORA_DISK_1: restore complete

Finished restore at 13-SEP-05

6、关闭数据库,使用使用spfile文件启动

RMAN> shutdown immediate

Oracle instance shut down

RMAN> startup nomount;

connected to target database (not started)

Oracle instance started

7、恢复控制文件

RMAN> restore controlfile;

Starting restore at 13-SEP-05

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=13 devtype=DISK

allocated channel: ORA_DISK_2

channel ORA_DISK_2: sid=14 devtype=DISK

allocated channel: ORA_DISK_3

channel ORA_DISK_3: sid=15 devtype=DISK

allocated channel: ORA_DISK_4

channel ORA_DISK_4: sid=16 devtype=DISK

channel ORA_DISK_1: starting datafile backupset restore

channel ORA_DISK_1: restoring controlfile

output filename=/oracle/oracle/app/oracle/product/9.2.0.1/dbs/hb130000/control01

.ctl

channel ORA_DISK_1: restored backup piece 1

piece handle=/oradata/rmanbackup/hb130000_ctl_c-2380174037-20050913-00.bak tag=n

ull params=NULL

channel ORA_DISK_1: restore complete

replicating controlfile

output filename=/oracle/oracle/app/oracle/product/9.2.0.1/dbs/hb130000/control02

.ctl

output filename=/oradata/hb130000/control03.ctl

Finished restore at 13-SEP-05

8、数据库mount

RMAN> alter database mount;

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of alter db command at 09/13/2005 14:13:42

9、数据库恢复。
