Oracle 重建控制文件

前些天在做Oracle数据库恢复测试时，因为一些异常操作导致控制文件出了问题，数据库无法正常使用，这里记录一下重建控制文件的操作

一、使用sysdba用户登入数据库

此时普通用户已无法链接数据库

二、启动数据库到mount状态

此时可以看出异常来源：由于控制文件中的实例名与实例本身实例名不一致导致数据库实例无法正常启用

三、获取创建控制文件的脚本格式

在Oracle中我们可以通过 alter database backup controlfile to trace; 命令获取控制文件的创建方法，但由于此时实例ORCL上的控制文件已经出现异常，我们无法在这个实例上获取.trc文件；不过我们可以使用这条命令在其他正常的实例上获取此文件，并根据实际情况创建重建控制文件的脚本。一下是具体方法：

获取文件，重命名并保存到/tmp目录下，方便查看

 [oracle@node00 ~]$ sqlplus / as sysdba

由于我们这里不需要重做重做日志，所以选择第一种方法。然后根据ORCL实例的重做日志和表空间路径，写出重建控制文件的脚本。
