RMAN】利用备份片还原数据库

BLOG文档结构图

群里有同学说把ORACLE_BASE目录删掉了,现在只有备份片和归档文件了,试问如何恢复。坑,,,,咋能这么干,ORACLE_BASE都敢删,,试着恢复了下,并且记录下来,当然软件安装部分就不记录了。

我再说说目前的情况,只有备份片和归档文件,且从文件名称是看不出dbname和dbid的,在这种情况下其实恢复控制文件是很重要的了,但是鬼知道备份片里边是不是有控制文件的备份呢?我们可能碰到的就是这样的情况,只有备份文件,其它的什么都不知道。我们且看这样的情况下如何恢复呢?

1.2  测试库编辑pfile文件

11g只写db_name即可,控制文件可以写上,免得后边又回来修改。

[oracle@testdb dbs]$ pwd

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

[oracle@testdb dbs]$ more initora11g.ora

db_name=ora11g

control_files='/u01/app/oracle/oradata/ora11g/control01.ctl','/u01/app/oracle/flash_recovery_area/ora11g/control02.ctl'

[oracle@testdb dbs]$

 

1.3  找回控制文件--备份集中含有控制文件

重点来了:

 

由于没有控制文件,所以首先只能启动数据库到nomount状态

[oracle@testdb dbs]$ ORACLE_SID=ora11g

[oracle@testdb dbs]$ rman target /

首先我们要判断一下备份集中是否含有控制文件的备份,如果有我们可以直接还原,如果没有那就只有创建控制文件了,那么如何判断备份集中是否含有控制文件的备份呢?这里提供几种办法:① 推荐: 采用dbms_backup_restore.restoreControlfileTo从备份片中来尝试找回控制文件 ②   尝试采用创建临时库来找回控制文件  ③ 其它第三方工具来解析备份集

 

1.3.1  方法一:采用dbms_backup_restore.restoreControlfileTo从备份片中来尝试找回控制文件

Oracle 816 以后的版本中,Oracle提供了一个包:DBMS_BACKUP_RESTORE. DBMS_BACKUP_RESTORE 包是由dbmsbkrs.sql prvtbkrs.plb 这两个脚本创建的.catproc.sql 脚本运行后会调用这两个包.所以是每个数据库都有的这个包是Oracle服务器和操作系统之间IO操作的接口.由恢复管理器直接调用。由此可见,我们可以在数据库nomount 情况下调用这些package ,来达到我们的恢复目的。

 

 

从前边的备份中我们知道control文件和spfile其实是在备份片:o1_mf_ncsnf_TAG20150430T160049_bn3rdxyz_.bkp中,但是这里我们假装不知道位置,然后挨个尝试一下:

[oracle@testdb dbs]$ ORACLE_SID=ora11g

[oracle@testdb 2015_04_30]$ ll

将控制文件中的原库备份信息删除,然后重新注册备份集。

 这里恢复到10号停止了,10号文件很有可能丢失或者是在线日志,如果是在线日志,且在线日志可以找到,那么我们就可以做完全恢复了,不用丢失数据了,这里不演示了,在其它方法中演示。这里我们重新启动数据库就会以spfile来启动数据库了,当然不建议使用shutdown abort来强制关库:

好,数据库已经恢复,后边要做的就是备份新库等其他操作,这里就不演示了,至于第二种办法且看下一篇blog。

 

 

 

在上一篇blog中我们介绍了采用dbms_backup_restore来找回控制文件并恢复整个数据库的方法,本篇blog我们介绍采用创建临时库来找回控制文件的方法。


1.1.1  方法二:尝试采用创建临时库来找回控制文件

 

由于RMAN必须工作在MOUNT模式,所有的数据文件都丢失,无法通过只重建控制文件将其启动到MOUNT模式,所以这里利用dbca创建一个临时数据库环境,数据库的名称与原有名称保持不变,文件存放到默认位置即可。

 

一、 搭建临时库来注册备份集

这里我们假设有一个临时环境供我们测试,ORACLE_SID=orcltest,由于是第二天做的测试,所以我重新对原库做了备份并传递到备份库

[root@rhel6_lhr backupset]#  scp -r 2015_05_02 oracle@192.168.59.129:/tmp

由下边的方法(备份集中无控制文件的备份)的方法得知,这里创建一个临时库的方法比较麻烦,不太推荐:

由此可以看出,命令catalog start with '/tmp/2015_05_02/'; 在异库注册可以查看到原库的信息:DBID: 4270446895  Database Name: ORA11G,(10g下测试也可以获取到这些信息)这里dbnamedbid都不一样所以不能注册在该数据库下,将备份片的信息加入到控制文件的时候报错,原因在于原有数据库和临时数据库的DBID不同,那么我们是否可以尝试修改临时数据库的DBID,使它与原有数据库DBID保持一致呢,试试呗。

 

1、 修改dbnamedbid

 

首先启动临时库到open read only状态,然后执行脚本:

我们可以看到,控制文件和spfile都在备份文件: /tmp/2015_05_02/o1_mf_ncsnf_TAG20150502T112355_bn8k97pm_.bkp 中,有归档文件,有数据文件,此时我们就可以考虑还原策略了,我们可以使用备份中的spfile和控制文件,也可以只还原数据文件,这个根据自己的需要而定,这里我们测试的话就从spfilecontrol filedatafile都还原吧。

 

二、 还原操作 1、 还原spfile

 

RMAN> restore spfile from '/tmp/2015_05_02/o1_mf_ncsnf_TAG20150502T112355_bn8k97pm_.bkp';

 

Starting restore at 02-MAY-15

allocated channel: ORA_DISK_1

channel ORA_DISK_1: SID=144 device type=DISK

 

channel ORA_DISK_1: restoring spfile from AUTOBACKUP /tmp/2015_05_02/o1_mf_ncsnf_TAG20150502T112355_bn8k97pm_.bkp

channel ORA_DISK_1: SPFILE restore from AUTOBACKUP complete

Finished restore at 02-MAY-15

 

RMAN>

 

[oracle@orcltest ~]$ cd $ORACLE_HOME/dbs

[oracle@orcltest dbs]$ ll spfile*

-rw-r----- 1 oracle oinstall 2560 May  2 13:21 spfileORA11G.ora

-rw-r----- 1 oracle oinstall 3584 May  2 12:57 spfileorcltest.ora

[oracle@orcltest dbs]$

 

 

2、 还原控制文件

 

RMAN> restore controlfile  to '/tmp/2015_05_02/cont.ctl'  from '/tmp/2015_05_02/o1_mf_ncsnf_TAG20150502T112355_bn8k97pm_.bkp';

 

Starting restore at 02-MAY-15

using channel ORA_DISK_1

 

channel ORA_DISK_1: restoring control file

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

Finished restore at 02-MAY-15

 

RMAN>

 

这里可以采用原数据库的控制文件,即现在还原出来的控制文件,也可以采用目前临时库的控制文件,都可以,当然,如果备份集中没有控制文件的备份的话我们可以考虑  采用临时库的控制文件,或者备份片段中没有控制文件的备份 这个方法。

 

3、 还原database

这里分情况,如果采用原库的控制文件的话,我们可以这样还原:

 

①、 方法一:采用原库控制文件--推荐

 

将原库控制文件拷贝到pfile定义的相关目录:

[oracle@orcltest orcltest]$ cp /tmp/2015_05_02/cont.ctl /u02/app/oracle/flash_recovery_area/orcltest/control02.ctl

[oracle@orcltest orcltest]$ cp /tmp/2015_05_02/cont.ctl /u02/app/oracle/oradata/orcltest/control01.ctl

[oracle@orcltest orcltest]$ cd /u01/app/oracle/oradata/ora11g/

[oracle@orcltest dbs]$ rman target /
