Media Recovery failed with error 12801

ORA-283 signalled during: ALTER DATABASE RECOVER  database  ...


从上面信息中抓取了一个信息:

Oracle代码

  1. ORA-10562: Error occurred while applying redo to data block (file# 1, block# 1658)  

ORA-10562: Error occurred while applying redo to data block (file# 1, block# 1658)


针对这个错误解决如下:

Oracle代码

  1. ORA-10562: Error occurred while applying redo to data block (file# string, block# string)   
  2. Cause: See other errors on error stack.   
  3. Action: Investigate why the error occurred and how important is the data block. Media and standby database recovery usually can continue if user allows recovery to corrupt this data block。  

ORA-10562: Error occurred while applying redo to data block (file# string, block# string)

Cause: See other errors on error stack.

Action: Investigate why the error occurred and how important is the data block. Media and standby database recovery usually can continue if user allows recovery to corrupt this data block。


从日志信息可以基本判断问题如下:
当前在线日志损坏,导致undo回滚段出现问题,又由于系统突然掉电,系统表空间在重启实例后要进行实例恢复,当前在线日志损坏,系统表空间无法进行recover,因而出现了上面的错误。
找到了问题,解决访问就有了。
由于没有备份,数据库也运行在非归档模式下,所以恢复如下步骤:

Sql代码

  1. SQL>startup mount   
  2. SQL>recover database using backup controlfile until cancel;   
  3. SQL>alter database open resetlogs;   
  4. SQL> startup mount   
  5. SQL> alter system set “_allow_resetlogs_corruption=true scope=spfile;   
  6. SQL>shutdown immediate   
  7. SQL> startup mount   
  8. SQL> alter database open resetlogs;   
  9. SQL> startup  

SQL>startup mount

SQL>recover database using backup controlfile until cancel;

SQL>alter database open resetlogs;

SQL> startup mount

SQL> alter system set “_allow_resetlogs_corruption=true scope=spfile;

SQL>shutdown immediate

SQL> startup mount

SQL> alter database open resetlogs;

SQL> startup


基本恢复步骤:

Sql代码

  1. SQL>startup mount   
  2. SQL>recover database using backup controlfile until cancel;   
  3. Cancel   
  4. SQL>alter database open resetlogs;   
  5. #此时会提示system表空间需要恢复,但是由于当前日志损坏,无法进行恢复,所以需要加入#隐含参数,oracle才不会监测scn的一致性,才能打开数据库。   
  6. #重启数据库加入隐含参数   
  7. SQL> startup mount   
  8. SQL> alter system set “_allow_resetlogs_corruption=true scope=spfile;   
  9. SQL> shutdown immediate   
  10. SQL> startup mount   
  11. SQL> alter database open resetlogs;
