ORACLE服务器异常断电，控制文件故障的处理步骤

这里只是简单的记录操作步骤，以做备忘。本步骤由同事邹启健(问心)完成

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

*

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;

SQL> CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS  NOARCHIVELOG

  2      MAXLOGFILES 16

  3      MAXLOGMEMBERS 3

  4      MAXDATAFILES 100

  5      MAXINSTANCES 8

  6      MAXLOGHISTORY 292

  7  LOGFILE

  8    GROUP 1 'G:\APP\ADMINISTRATOR\ORADATA\ORCL\REDO01.LOG'  SIZE 50M BLOCKSIZ

E 512,

  9    GROUP 2 'G:\APP\ADMINISTRATOR\ORADATA\ORCL\REDO02.LOG'  SIZE 50M BLOCKSIZ

 10    GROUP 3 'G:\APP\ADMINISTRATOR\ORADATA\ORCL\REDO03.LOG'  SIZE 50M BLOCKSIZ

E 512

 11  DATAFILE

 12    'G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSTEM01.DBF',

 13    'G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSAUX01.DBF',

 14    'G:\APP\ADMINISTRATOR\ORADATA\ORCL\UNDOTBS01.DBF',

 15    'G:\APP\ADMINISTRATOR\ORADATA\ORCL\USERS01.DBF',

 16    'G:\APP\ADMINISTRATOR\ORADATA\ORCL\EXAMPLE01.DBF'

 17  CHARACTER SET ZHS16GBK;

CREATE CONTROLFILE REUSE DATABASE "ORCL" NORESETLOGS  NOARCHIVELOG

ORA-01503: CREATE CONTROLFILE ??

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

控制文件已创建。

SQL> alter database mount;

alter database mount

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.

ERROR at line 1:

ORA-01100: database already mounted

SQL> alter database open resetlogs;

alter database open resetlogs

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;

ORA-00279: change 28088746 generated at 12/16/2017 20:32:45 needed for thread 1

ORA-00289: suggestion :

G:\APP\ADMINISTRATOR\FLASH_RECOVERY_AREA\ORCL\ARCHIVELOG\2017_12_19\O1_MF_1_572_%U_.ARC

ORA-00280: change 28088746 for thread 1 is in sequence #572

Specify log: {=suggested | filename | AUTO | CANCEL}

ORA-00308: cannot open archived log

'G:\APP\ADMINISTRATOR\FLASH_RECOVERY_AREA\ORCL\ARCHIVELOG\2017_12_19\O1_MF_1_572_%U_.ARC'

ORA-27041: unable to open file

OSD-04002: ????????????

O/S-Error: (OS 2) ??????????????????????

SQL> archive log list;

Database log mode              No Archive Mode

Automatic archival             Disabled

Archive destination            USE_DB_RECOVERY_FILE_DEST

Oldest online log sequence     0

Current log sequence           0

G:\app\Administrator\oradata\orcl\REDO01.LOG

ORA-00310: archived log contains sequence 571; sequence 572 required

ORA-00334: archived log: 'G:\APP\ADMINISTRATOR\ORADATA\ORCL\REDO01.LOG'

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

Log applied.

Media recovery complete.

ORA-01589: must use RESETLOGS or NORESETLOGS option for database open

Database altered.

SQL> select file_name from dba_data_files;

FILE_NAME

G:\APP\ADMINISTRATOR\ORADATA\ORCL\EXAMPLE01.DBF

G:\APP\ADMINISTRATOR\ORADATA\ORCL\USERS01.DBF

G:\APP\ADMINISTRATOR\ORADATA\ORCL\UNDOTBS01.DBF

G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSAUX01.DBF

G:\APP\ADMINISTRATOR\ORADATA\ORCL\SYSTEM01.DBF

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup;

ORACLE instance started.

数据库已经打开。

至此恢复完成
