数据库启动报错

 代码如下 复制代码
SQL> startup mount pfile='c:＼pfile.txt'

ORACLE 例程已经启动。

跟踪数据库启动过程
这里可以清晰的看到是因为block 404有坏块,数据库递归sql访问到该坏块报错,从而数据库无法继续open,对数据库启动过程做10046跟踪

根据我们的经验,对数据库启动影响很大的,主要是403,404,498三个坏块,在10201的库中查询得出结论(403,404是rollback,498是seq$).那现在我们可以理解在数据库启动过程中需要undo$表中相关列信息,但是由于rollback对应的block有坏块,使得数据库无法操作update操作,从而无法正常启动.
SQL> SELECT OWNER, SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME, A.PARTITION_NAME

输入 file_id 的值:  1
原值    3:  WHERE FILE_ID = &FILE_ID
新值    3:  WHERE FILE_ID = 1
输入 block_id 的值:  404
原值    4:    AND &BLOCK_ID BETWEEN BLOCK_ID AND BLOCK_ID + BLOCKS - 1
新值    4:    AND 404 BETWEEN BLOCK_ID AND BLOCK_ID + BLOCKS - 1

常用方法
设置event跳过坏块,使用隐含参数屏蔽回滚段
 

 代码如下 复制代码

这里可以看出来,数据库在update undo$的时候因为rollback异常无法通过屏蔽回滚段和跳过坏块的方法来解决。因为是system undo系统块,想法就是从别的相同版本库中拷贝一个相同位置块过来试试看。

Error 604 happened during db open, shutting down database
USER: terminating instance due to error 604
这里是因为我们拷贝了一个其他库的undo段过来，然后数据库启动的时候首先使用到该undo块和rollback segment header 不匹配,所以通过通过修改undo header 来修复,使用bbed修改段头信息,因为在以前的文章中描述过,在此不再重复,具体参考:使用bbed解决ORA-00607/ORA-00600[4194]故障启动数据库
SQL> startup mount pfile='c:＼pfile.txt'
ORACLE 例程已经启动。

数据库装载完毕。
SQL> recover database;
完成介质恢复。
SQL> alter database open upgrade;
 
数据库已更改。
但是因为seq$有坏块,数据库启动后,如果使用非系统认证登录数据库会报如下错误

连接到:

With the Partitioning, OLAP and Data Mining options
 
SQL> select object_type from dba_objects where object_name='AUDSES$';
 
OBJECT_TYPE
-------------------
SEQUENCE

因为seq$有坏块导致该问题，因为该数据库需要重建,使用exp导出来数据，然后重建完成相关工作
