重启实例，重建ctl成功.尝试恢复库提示需要很久之前的日志，因为有两个数据文件scn异常

通过oracle recovery tools修改文件头

再次recover数据库成功顺利open库导出客户需要数据

存储强制拉lun导致数据库异常恢复

标题：存储强制拉lun导致数据库异常恢复

客户那边反馈有几个lun异常,无法正常online

通过存储工程师强制拉起来lun(清除掉了cache),但是数据库无法正常mount

可以要求保护第一现场,把asm中的数据恢复到文件系统中,然后进行恢复,由于客户是10g的环境,无法直接使用asmcmd中的cp实现此项操作,数据库也没有mount成功(无法使用rman的copy),考虑使用oracle的amdu实现此项操作需求.在拷贝过程中报AMDU-00204报错

确认此报错（AMDU-00204 LEM-00031）对于拷贝出来的数据文件无直接影响，可以忽略,拷贝出来所有文件进行重建ctl，报ORA-01159错误

由于部分文件不是该库的,通过进一步分析,除掉不是该库的文件,重建ctl文件成功.尝试recover数据库，报大量ORA-07445错误，由于cache丢失redo损坏导致,此类操作可能导致数据文件损坏【恢复需要谨慎,最好对数据文件做一次备份】

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

这个错误和以往版本中的kccpb_sanity_check_2比较类似,由于数据库异常关闭导致ctl写丢失导致
ORA-600 2131/kccpb_sanity_check_2解释

DESCRIPTION:

  This internal error is raised when the sequence number (seq#) of the
  current block of the controlfile is greater than the seq# in the controlfile header.

  The header value should always be equal to, or greater than the value
  held in the control file block(s).

  This extra check was introduced in Oracle 10gR2 to detect lost writes
  or stale reads to the header.

ARGUMENTS:
  Arg [a] seq# in control block header.
  Arg [b] seq# in the control file header.
  Arg 1 

FUNCTIONALITY:
  Kernel Cache layer Control file component.

数据库恢复的敏感性—重建控制文件使用不合适数据文件

标题：数据库恢复的敏感性—重建控制文件使用不合适数据文件

有客户数据库由于某种原因无法open,请求我们技术支持.通过检查alert日志发现数据库是由于ORA-600 kccpb_sanity_check_2错误.并且他们已经重建控制文件,通过我们的Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)
datafile 6 异常

通过这里我们发现datafile 6 数据文件头是干净的,而且对应的redo seq为5270,而其他文件头都是fuzzy,而且对应的redo为295902613.这里怀疑datafile 6 可能是错误的.当然对于这样scn相距比较大的情况,我们可以通过隐含参数,修改scn等方法强制让该库起来(或者该文件online),但是从现在看到的情况,文件很可能异常,这样强制恢复,可能没有实际意义.
分析alert日志

这个里面可以发现是先删除了sde表空间,然后创建了同一个表空间,只是数据文件路径不一样了.而且正好在seq为5270的地方操作的.现在出现datafile 6异常的原因已经清楚,就是创建数据控制文件的时候,使用了错误的数据文件导致.

这个库比较幸运,客户发现异常之后,里面停止了有风险性的操作(比如使用_allow_resetlogs_corruption参数,resetlogs库等),使得数据完美恢复0丢失.如果条件允许最好使用老的控制文件来重建新控制文件,而不要通过人工去系统中找数据文件来实现恢复,这样很可能有遗落或者使用错误的数据文件

使用新的控制文件位置，这次终于数据库重建控制文件成功
尝试指定redo进行恢复，数据库正常打开

数据库恢复完成。整个数据库恢复比较简单，但是注意这里的ORA-600[kccsga_update_ckpt_4]通过修改控制文件路径规避，具体原因待查。

知识点补充：ORA-600 [kccpb_sanity_check_2] [a] [b] {c}

VERSIONS:
  Versions 10.2 to 11.2

DESCRIPTION:

  This internal error is raised when the sequence number (seq#) of the
  current block of the controlfile is greater than the seq# in the controlfile header.

  The header value should always be equal to, or greater than the value
  held in the control file block(s).

  This extra check was introduced in Oracle 10gR2 to detect lost writes
  or stale reads to the header.

ARGUMENTS:
  Arg [a] seq# in control block header.
  Arg [b] seq# in the control file header.
  Arg {c}

标题：记录一次ORA-600 kccpb_sanity_check_2和ORA-600 kcbgtcr_13 错误恢复

晚上朋友告诉我数据库不能open,请求技术支持,检查alert日志发现ORA-00600[kccpb_sanity_check_2]错误导致数据库无法正常mount

Fri Jun  6 23:36:08 2014
alter database mount
Fri Jun  6 23:36:08 2014
This instance was first to mount
Fri Jun  6 23:36:12 2014
Errors in file /on3000/oracle/admin/on3000/udump/on30001_ora_295198.trc:
ORA-00600:内部错误代码, 参数:[kccpb_sanity_check_2], [18045], [17928], [0x000000000], [], [], [], []
ORA-600 signalled during: alter database mount...

依次替换三个控制文件依然无法解决该问题。查询MOS得到解释为[435436.1]

ORA-600 [kccpb_sanity_check_2] indicates that the seq# of the last read block is
higher than the seq# of the control file header block. This is indication of
the lost write of the header block during commit of the previous cf transaction.

出现该故障的原因是因为写丢失导致,而解决该故障的方法有

1) restore a backup of a controlfile and recover

OR

2) recreate the controlfile

OR

3) restore the database from last good backup and recover

该数据库为无备份非归档数据库,因此只能重建控制文件来解决ORA-00600[kccpb_sanity_check_2]故障,通过重建控制文件数据库mount成功.但是在open的过程中又出现需要一个不存在的归档日志(数据库一个节点5月5日异常,另外一个节点5月23日异常,到6月6日我接手中间进行了N多操作,未细细分析原因).
Oracle Database Recovery Check Result检查结果
数据库SCN

控制文件中关于数据文件SCN

数据文件头SCN

REDO SCN

这里明显表示thread#缺少归档,导致恢复过程出现如下提示

最后没有办法只能使用_allow_resetlogs_corruption参数跳过redo,然后去open数据库,很不幸出现更加悲催的ORA-00704和ORA-00600[kcbgtcr_13]错误,导致数据库open失败

这里可以知道,数据库在读取obj$的时候使用到了undo cr块的构造,由于某种原因导致构造cr块失败,从而出现ORA-00600[kcbgtcr_13]错误,而因为obj$又在bootstarp$里面,因此又出现ORA-704.所以解决该问题的方法就是让数据库在查询obj$表的时候不再进行cr块构造,比如使用bbed提交事务等方法解决.这里使用bbed提交事务(bbed模拟提交事务一之修改itl),数据库启动成功

ORA-600 signalled during: ALTER DATABASE   MOUNT...

错误原因

ORA-600 [kccpb_sanity_check_2] indicates that the seq# of the last read block is
higher than the seq# of the control file header block. This is indication of
the lost write of the header block during commit of the previous cf
transaction.

解决方法

1) restore a backup of a controlfile and recover

OR

2) recreate the controlfile

OR

3) restore the database from last good backup and recover

NOTE:  If you do not have any special backup of control file to restore and you are using Multiple Control File 
copies in your pfile/init.ora/spfile you can attempt to mount the database using each control file one by one.  
If you are able to mount the database with any of these control file copies you can then issue 
'alter database backup controlfile to trace' to recreate controlfile.
