121231异机恢复oracle数据库

 异机恢复oracle数据库；

 

找新的一台虚机，安装oracle数据库，并创建默认数据库。需要注意以下几点：

1.         恢复目标机target db的instance name，sid以及数据库名称需与source db 恢复源db的名称保持一致，在目标恢复机恢复时copy备份数据到fra flashrecoverarea且设置源的dbid；

2.         恢复目标机target db的数据库字符集编码需要与source db恢复源db的字符编码保持一致；

Copy test.rar压缩包中的源source db的flash_recovery_area目录，到target db的flash_recovery_area目录；

最终第一次尝试恢复失败,失败原因是已经在target db目标数据库中创建了数据库,不是创建了就无法恢复,而是如果源和目标sid不一样,如何修改尚不得而知;

 

使用deinstall反安装数据库;

 

创建fra flash_recovery_area目录，oradata目录等rman恢复需要的目录；

 

对数据库软件重新进行安装,在安装时不创建数据库,自然也不需要创建数据库；只保留数据库软件即可；

 

        C:\Windows\system32>oradim -new -sid test

        Instance created.

    

重建数据库instance，sid名称需要与源数据库source db的名称一致；

 

C:\Windows\system32>orapwd file=c:\app\Azar\product\11.2.0\test\database\PWDTEST.ora password=Test123

 

重建密码文件；

从数据库文件中恢复spfile，需要知道spfile存在于哪个rman备份中；

 

查询源sourceDB数据库：

RMAN> list backup of spfile;

备份集BS 33中文件就是spfile和controlfile的备份文件；

将该文件恢复到d盘pfile18.txt；

 

此处容易出错，恢复完pfile后，需要使用该pfile startup nomount，如果不使用该pfile进行挂载，则后面恢复controlfile是只能恢复到默认位置，并不是sourceDB源数据库应该恢复的位置及数量；

 

RMAN> restore controlfile from 'D:\oracle\flash_recovery_area\test\AUTOBACKUP\20

这个位置和数量是错的

 

        先挂载恢复出来的pfile

        Startup nomount pfile=‘d:\pfile18.txt’；

        然后通过该pfile生成spfile；

        Select spfile from pfile;

        然后再恢复controlfile；

 

RMAN> restore controlfile from 'D:\oracle\flash_recovery_area\test\AUTOBACKUP\20
