oracle exadata force open

这个库的恢复有一些历史故事(【力荐】Exadata火线救援:10TB级数据修复经典案例详解!):xx运营商x2的1/4配置的oracle exadata机器,跑了近6年,最近有一个cell节点主机异常,在rebalance过程中,只有两个节点的cell其中一个节点坏了一个硬盘导致.导致asm diskgroup无法正常mount,最后该运营商运维三方通过amdu把该一体机中的数据文件全部抽出来,然后在恢复过程中出现大量错误无法解决,请求我们支持

这个错误比较常见,可以通过推scn就可以解决,由于已经安装了scn patch,通过oradebug推scn解决该问题.

ORA-600 4194
这个ora 600 4194相对比较特殊,在SMON: enabling cache recovery之后立马报出来,然后实例直接open失败.

ORA-600 signalled during: alter database open...

数据库正常open失败,但是可以upgrade启动.根据对trace文件的分析,定位到问题在HISTGRM$表上面,进一步分析该表结构为

CREATE TABLE SYS.HISTGRM$
(
  OBJ#      NUMBER,
  COL#      NUMBER,
  ROW#      NUMBER,
  BUCKET    NUMBER,
  ENDPOINT  NUMBER,
  INTCOL#   NUMBER,
  EPVALUE   VARCHAR2(1000 BYTE),
  SPARE1    NUMBER,
  SPARE2    NUMBER
)
CLUSTER SYS.C_OBJ#_INTCOL#(OBJ#, INTCOL#);

这个和ORA-600 6711错误相匹配了

ERROR:
ORA-600 [6711] [a] [b] 1 [d]
VERSIONS:
versions 6.0 to 12.1
DESCRIPTION:
This error is generated when we find more blocks on a cluster key
chain than are supposed to be there.
Usually this indicates that the chain contains a loop within itself. We
cannot have more than 65535 blocks in a chain.
ARGUMENTS:
Arg [a] beginning DBA
Arg [b] table slot number (in table index)
Arg {c} dba of key next in chain
Arg [d] row slot of key next in chain

需要处理该错误,也就是需要处理CLUSTER SYS.C_OBJ#_INTCOL#,这个可以通过重建来实现,但是当重建之时发生

ORA-00600: internal error code, arguments: [kkoipt:invalid aptyp], [0], [0], [], [], [], [], [], [], [], [], []
ORA-08102: index key not found, obj# 39, file 1, block 1374829 (2)

这里错误比较明显obj#=39为obj$的i_obj4的index的记录和表不匹配,导致任何ddl无法执行,因此如果要处理C_OBJ#_INTCOL#就必须要先处理i_obj4的问题.通过一些技巧重建i_obj4,然后重建C_OBJ#_INTCOL#,数据库终于可以正常打开.由于大量数据字典不一致,exp/expdp导出依旧有问题,通过dblink直接拉数据到新库,完成本次恢复
补充说明:1. 在这个库的恢复过程中,我们还使用了大量的event和隐含参数,因为比较常规而且不涉及核心环节,因为未列举出来;2. 由于当时操作记录未能够保留日志因此相关操作步骤无法贴出来,本文只能提供恢复处理思路
再次提醒各位数据库做好备份,做好巡检工作,哪怕是强大的Oracle exadata也禁不起无备份折腾,数据重于一切

recreate crontrolfile lost datafile—-MISSING0000N

在Oracle职业生涯中,恢复过生产环境数据库也有几百个.对于Oracle恢复我还是相当的自信,今天因为自己的一时过于自信,对于环境错了错误的判断,简单问题复杂化,差点变成悲剧

控制文件已创建。

这一步严重发错,在恢复前未认真看alert日志,太依赖v$datafile查询出来结果,导致重建控制文件丢失数据文件,埋下大雷。根据前面alert日志报错ORA-600 2662,决定一并处理该问题,然后进行恢复

还好结合一些隐含参数侥幸恢复成功,差点到了要使用bbed的程度

这次的恢复告诉我:Oracle数据库恢复千万比大意,需要认真分析alert日志和咨询客户做了那些操作,不然可能导致万劫不复之禁地

Completed: alter database open

尝试重建undo表空间并切换undo_tabspace到新undo表空间解决,因为数据库在恢复过程中使用了隐含参数强制拉库,不能保证数据一致性,强烈建议逻辑方式重建数据库
在本次故障中,所幸的是只有redo和sysaux文件损坏,如果是业务数据文件或者system数据文件损坏,恢复的后果可能更加麻烦,丢失数据可能更加多。再次说明:数据库备份非常重要,数据的安全性不能完全寄希望于硬件之上

ORA-600 4194这个错误在数据库异常恢复中非常常见,因为库不是很重要,因此就是直接屏蔽掉故障回滚段,然后强制拉库,该库的恢复过程中,也直接使用隐含参数屏蔽回滚段

这里很明显看出来,数据库是在open过程中,update undo$表遭遇到ORA-600 4194,因为该过程需要使用系统回滚段,但是由于其所对应的undo和redo信息不一致,所以无法正常启动数据库.继续读trace文件

通过这里可以看出来,数据库在启动的时候,使用system undo的block为为0×00400006,使用bbed清除掉该uba记录,让数据库启动的时候重新分配system undo block给数据库执行update undo$使用,数据库open成功

ORA-607/ORA-600[4194]不一定是重大灾难

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:

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.
