oracle startup 之后 如果执行SQL 那么立马shutdown 原因分析

事故场景    当我数据库使用的时候，突然断电了。然后就出现了下边的症状。

oracle startup  之后  如果执行SQL 那么立马shutdown 原因分析

排查步骤 ： 

1    根据 alter_orcl.log  查找错误。然后在trc里面找明细的错误。

如图：

2    发现时 ora-00600错误。 然后引用了一遍其他人的文章。具体如下。

Ora-00600 4193一般来说是undo表空间的问题。

我们来看看一个实例 
在trc文件里出现 

Fri Dec 16 22:37:27 2005 Errors in file /opt/oracle/admin/orcl/bdump/orcl_smon_22817.trc:ORA-00604: error occurred at recursive SQL level 1ORA-00607: Internal error occurred while making a change to a data blockORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], []Fri Dec 16 23:28:40 2005Errors in file /opt/oracle/admin/orcl/bdump/conner_smon_22817.trc:ORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], [] 

4193错误通常是因为恢复时redo与undo不一致所导致。 

Oracle的解释如下: 

引用:

While backing out an undo record (i.e. at the time of rollback) we found a transaction id mis-match indicating either a corruption in the rollback segment or corruption in an object which the rollback segment is trying to apply undo records on. 

This would indicate a corrupted rollback segment. 

检查具体的Trace文件，可以发现类似如下错误： 

*** 2005-12-16 20:54:53.496 
ksedmp: internal or fatal error 
ORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], [] 
Current SQL statement for this session: 
UPDATE SMON_SCN_TIME SET SCN_WRP=:1, SCN_BAS=:2, TIME_MP=:3, TIME_DP=:4 
WHERE TIME_MP = :5 AND THREAD = :6 AND ROWNUM <= 1 

由于是UNDO存在不一致，可以通过重建UNDO表空间来解决: 

SQL> create undo tablespace undotbs2 
2 datafile '/opt/oracle/oradata/orcl/undotbs2.dbf' size 10m; 

Tablespace created. 

SQL> alter system set undo_tablespace=undotbs2 scope=both;

undo_management string AUTO 
undo_retention integer 10800

SQL> drop tablespace undotbs1 including contents and datafiles; 

Tablespace dropped. 


至此，Ora-600 4193错误不再出现。 

从alert文件中，可以看到自动控制文件备份生效：
