一.说明

 

     RMAN 备份分2种,Catalog 和Nocatalog,对于Nocatalog,oracle 会使用控制文件来保存RMAN备份的一些记录。 而且实际上多数也是使用Nocatalog来备份。因为使用Nocatalog比较方便。

 

    但对于使用Nocatalog的情况就会让RMAN 恢复的时候依赖与控制文件中记录的备份的信息。如果不一致,就会导致不能进行有效的恢复。

 

我们这里演示二种情况:

(1)  使用RMAN 的nocatalog 进行备份,然后将备份转移到其他的目录, 在进行恢复。

(2)  使用Nocatalog 备份,然后重建控制文件,在使用RMAN 备份进行恢复。

 

两种方法都是使用catalog 命令把RMAN备份集的信息重新注册到控制文件。

 

 

二.备份集位置发生改变

 

在我们RMAN 进行异地恢复的时候,就会遇到路径的问题,如果路径不同,就没办法进行有效的恢复,我们看这时候怎么处理。

 

2.1 使用RMAN Nocatalog 进行全库备份

 

Nocatalog 下的RMAN 增量备份 shell脚本

2.2 查看备份信息

 

[oracle@dave scripts]$ exportNLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"

 

[oracle@dave scripts]$ rman target /

这里通过list 命令查看,也可以通过如下视图来查看详细信息:

通过V$BACKUP_PIECE 查询出来的备份集:

我这里备份集保存在/u01/backup的目录:

2.5 将备份集重新注册到控制文件

 

因为之前备份集的位置发生改变,导致corsscheck之后,将之前备份的记录标记为expired,我们后来手工删除了这些expired的备份集信息。

 

现在我们要进行恢复,必须将之前的备份信息重新注册到控制文件中来。

 

2.5.1 方法一:注册单个备份片

 

RMAN> CATALOG BACKUPPIECE '/u01/bak/arch_0no76njh_1_1_20130416','/u01/bak/ctl_file_0oo76njm_1_1_20130416';

---ASM:

CATALOG START WITH '+disk'; # catalog allfiles from an ASM disk group

 

--本地目录:最后一定要加/

CATALOG START WITH '/fs1/datafiles/'; #catalog all files in directory

 

--有多个目录,注册多次:

RMAN> catalog start with'/data01/';  
RMAN>catalog start with '/data02/';  
RMAN>catalog start with '/data03/';

 

 

--示例:

RMAN> catalog start with '/u01/bak';

成功恢复。

 

 

三 .重建控制文件

 

    第二节中我们演示的备份集的位置发生改变。那么还有另一种情况,就是控制文件被重建了。 这时候也会清空RMAN 备份中的相关信息。

 

    而重建控制文件又分两种情况:resetlogs 和noresetlogs。

 

Oracle 控制文件 说明

http://blog.csdn.net/tianlesoftware/article/details/4974440

 

使用使用resetlogs 重建控制文件后,RMAN恢复又会涉及到incarnation 问题,而Noresetlogs 就不会出现这种问题。

 

    我们这里演示Noresetlogs 的方式重建控制文件并恢复的问题。

 

 

3.1 使用RMAN Nocatalog 进行全库备份

 

Nocatalog 下的RMAN 增量备份 shell脚本

http://blog.csdn.net/tianlesoftware/article/details/6164931

 

 

3.2 查看备份信息

 

[oracle@dave bak]$ exportNLS_DATE_FORMAT="YYYY-MM-DD HH24:MI:SS"

3.3 使用noresetlogs重建控制文件
