ORA-607/ORA-600[4194]不一定是重大灾难

发表于 2012 年 9 月 1 日 由 惜分飞

以前解决过ORA-607/ORA-600[4194]和模拟过ORA-607/ORA-600[4194]错误,所以固定思维任务ORA-607/ORA-600[4194]可能就是重大灾难,通过这个案例来说明ORA-607/ORA-600[4194]可能也就是一个常规的不能再常规的错误:有一网友数据库因意外关闭电源导致启动过程出现ORA-00607/ORA-00600[4194]/ORA-00600[4097]的错误,使得数据库启动失败.

通过alert日志可以定位到SMON_SCN_TIME表或者其回滚操作可能异常,结合alert和trace分析,发现这次错误的操作主要sql语句为:

ksedmp: internal or fatal error

   TIM_SCN_MAP)
VALUES
  (0, :1, :2, :3, :4, :5, :6, :7)

这里主要涉及到对oracle的三张表的操作
COL_USAGE$:主要是在收集统计信息的时候作为是否需要收集列直方图信息参考
MON_MODS$:Oracle主要利用该表来记录那些表的数据发生改变,方便收集统计信息
SMON_SCN_TIME:记录SCN和TIME的对应关系
通过这里的分析可以确定这三张表中的数据对于数据库来说不是致命的基表信息,在数据库运行过程中可以清理掉这些信息,最多就是因为数据库性能的下降或者SCN和TIME互转功能不完善.

解决思路
完整的undo异常处理顺序
1.从alert中可以看出来数据库是在open之后由于SMON回滚到上述几条sql异常导致数据库down,所以可以尝试使用system回滚段启动数据库,看看是否可以屏蔽相关问题
2.如果方法1不可行,那使用event屏蔽smon对回滚段的相关操作,使得数据库正常启动
3.如果由于存在特殊事务,event无法屏蔽,尝试使用隐含参数处理该问题
4.如果隐含参数尚无法解决给问题考虑使用bbed
5.如果bbed不能解决,那只能选择dul或者其类似工具处理
这个案例中我们明确的看到是因为上面的三条sql回滚异常出现问题导致,对于这样的问题,经过测试使用方法1和2都能够顺利解决问题(open库之后需要重建undo,删除有问题undo表空间,修改参数[可能包括event],切换undo表空间).因为遇到几次ORA-607/ORA-600[4194]是因为system rollback损坏导致,所以这次开始也认为是一次比较复杂的恢复,最后证明这次是一种非常常规的恢复.对于ORACLE的数据库恢复有经验可能会比较快的定位问题,但是如果按照固定的思路去想可能会让自己走进死胡同.

--------------------- Binary Stack Dump ---------------------

数据库在open的时候,需要去修改undo$对象的状态,从2该为3(offline->online)这个时候需要使用到系统回滚段,但是在使用系统回滚段的时候,使用uba=0×00400012的时候发生异常,导致数据库不能正常open,从而出现了ORA-00600[4194]的错误.而出现这个故障的原因,很可能是由于file 1 block 18块的异常导致.我们需要做的,就是让数据库启动的时候不使用file 1 block 18的block,而让数据库去另外的分配一个undo块.

通过bbed模拟ORA-00607/ORA-00600 4194 故障

发表于 2012 年 8 月 8 日 由 惜分飞

在数据库恢复的案例中,遇到system rollback异常的故障算是中彩票了.处理起来比较麻烦,有些情况甚至是无法处理.这里通过试验模拟ORA-00607/ORA-00600[4194].类此的错误在一次银联的数据库恢复中也遇到过,不过当时由于功底不深,理解出现部分误差.
