这篇文章给大家介绍 ORACLE 服务器异常断电及控制文件故障的处理步骤是什么，内容非常详细，感兴趣的小伙伴们可以参考借鉴，希望对大家能有所帮助。

这里只是简单的记录操作步骤，以做备忘。

一、版本

SQL select * from v$version;

BANNER
——————————————————————————–
Oracle Database 11g Enterprise Edition Release 11.2.0.1 .0 – Production
PL/SQL Release 11.2.0.1 .0 – Production CORE 11.2.0.1

二、故障
SQL startup mount;
ORACLE 例程已经启动。

Total System Global Area 1046224896 bytes
Fixed Size 1379212 bytes
Variable Size 708838516 bytes
Database Buffers 331350016 bytes
Redo Buffers 4657152 bytes
数据库装载完毕。
SQL alter dabase open;
alter dabase open
*
第 1 行出现错误:
ORA-00940: 无效的 ALTER 命令

SQL alter database open;
alter database open
*
第 1 行出现错误:
ORA-01122: 数据库文件 1 验证失败
ORA-01110: 数据文件 1: G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSTEM01.DBF
ORA-01207: 文件比控制文件更新 – 旧的控制文件

三、处理步骤

SQL alter database backup controlfile to trace as G:\ctl1.txt

数据库已更改。

SQL shutdown immediate;
ORA-01109: 数据库未打开

已经卸载数据库。
ORACLE 例程已经关闭。
SQL startup nomount;
ORACLE 例程已经启动。

第 1 行出现错误:

ORA-01229: data file 2 is inconsistent with logs
ORA-01110: data file 2: G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSAUX01.DBF
我们使用 resetlogs 进行重建避开和 redo logs 的校验

SQL CREATE CONTROLFILE REUSE DATABASE ORCL RESETLOGS NOARCHIVELOG

17 CHARACTER SET ZHS16GBK;
控制文件已创建。

SQL alter database mount;
alter database mount
*
第 1 行出现错误:
ORA-01100: ??????

SQL alter session set nls_language= american – 中文字符集显示乱码，需要更改 session 字符集
Session altered.
SQL alter database mount;
alter database mount
*
ERROR at line 1:
ORA-01100: database already mounted

SQL alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSTEM01.DBF

进行 recover 数据库，需要使用 resetlogs 和手动指定归档日志这里其实就是 redolog 中的一个

SQL recover database;
ORA-00283: recovery session canceled due to errors
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done

SQL recover database using backup controlfile;

G:\app\Administrator\oradata\orcl\REDO02.LOG 这里指定是 redolog 中的一个
