某医院存储掉线导致Oracle数据库故障恢复

xx医院存储突然掉线,导致数据库异常,现场工程师折腾了一天,问题依旧没有解决,无奈之下找到我们,希望我们能够帮忙恢复数据库.
启动报ORA-00600[2131]错误

出现该错误的原因是由于:We are attempting to write a controlfile checkpoint progress record, but find we do not have the progress record generating this exception.由于控制文件异常导致,出现此类情况,我们一般使用单个控制文件一次尝试,如果都不可以考虑重建控制文件

由于坏块(逻辑/物理)导致数据库实例恢复无法进行

这里是比较熟悉的ora-600[kclchkblk_4]错误,和ora-600[2662]错误类似,需要调整scn,由于数据库版本为11.2.0.4,无法使用常规方法调整scn,在修改控制文件,oradebug,bbed方法可供选择

使用oradebug方法处理
因为是asm环境,其他方法处理起来都相对麻烦

USER: terminating instance due to error 600
Instance terminated by USER, pid = 2105454
ORA-1092 signalled during: alter database open resetlogs...

ORA-600[KCLCHKBLK_4], is signaled because the SCN in a tempfile block is too high.
The same reason caused the ORA-600[2662]s in the alert logs.
因为是临时文件的scn太大的问题,那就比较好解决:
启动数据库到mount状态,查询出来相关temp file,然后drop掉.

这里的4193和4194是比较熟悉的,根据这里的提示猜测6856也是和undo有关系
ORA-600[6856]SMON is trying to recover a dead transaction.
But the undo application runs into an internal error (trying to delete a row that is already deleted).
因为smon回滚的时候出现上面错误,解决方法是想办法终止回滚,使用event=”10513 trace name context forever, level 2″.

太常见错误,不再做说明,虽然使用event是的库open成功,因为部分回滚段有问题,该错误还是会出现(还是喜欢直接屏蔽回滚段)

This error could be the result of a corruption and involves the parallel rollback that SMON enables each startup.
解决:fast_start_parallel_rollback=false

ORA-00600[kturacf1]错误未查询到原因
ORA-00600[kcbgcur_9]错误原因可能是:Buffers are pinned in a specific class order to prevent internal deadlocks.
因为这两个错误是job产生非致命错误,在这次的处理过程中可以忽略

ORA-00600[4097]

Errors in file /oracle/admin/odsdb/bdump/odsdb1_j000_1716282.trc:

ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], []

When an instance has a rollback segment offline and the instance crashes, or
the user does a shutdown abort, the rollback segment wrap number does not get
updated. If that segment is then dropped and recreated immediately after the
instance is restarted, the wrap number could be lower than existing wrap
numbers. This will cause the ORA-600[4097] to occur in subsequent
transactions using Rollback.
这个错误也是因为回滚段wrap number未被及时更新导致的异常.

总结这次恢复过程
1.因当前redo丢失,使用隐含参数打开库,然后出现ORA-600[KCLCHKBLK_4](这个错误比较少见,更何况这个库是10.2.0.4)
2.undo出现问题出现ORA-00600[6856]错误不是很多见
3.接下来都是一些列undo导致的问题,其实如果开始就直接使用隐含参数删除掉有问题回滚段,效果可能会比event好.
4.因为部分trace文件没有拿到,未做深入分析,文章列出整体恢复思路
5.本次恢复的数据库版本是10.2.0.4,根据mos描述,很多错误应不会发生,但是实际还是发生了,MOS的版本范围,不要太看重.
6.其实这篇文章的本质不是展示恢复过程,而是再一次提醒:操作数据库慎重,特别是一台机器上多套库.
