今天是有人在淘宝旺旺上找我，需要oracle数据库恢复支持
wangwang

远程登录上去一看发现数据库mount的时候报ORA-600[kccpb_sanity_check_2]错误

无论是使用noresetlogs还是resetlogs，重建控制文件都报ORA-600[kccsga_update_ckpt_4]错误.比较奇怪，无解指定控制文件新名称重建试试看

修改控制文件路径

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}

Oracle异常恢复前备份保护现场建议—ASM环境

标题：Oracle异常恢复前备份保护现场建议—ASM环境

在上一篇中写道了文件系统的库,在进行异常恢复前的备份方法（Oracle异常恢复前备份保护现场建议—FileSystem环境）,对于asm库,因为asm 里面的数据文件无法直接dd文件头,因此备份方式也有所改变.对于asm是mount,但是数据库不能打开,使用rman或者asm的cp命令全部备份数据文件也来不及或者空间不足,这样的情况下,你可以考虑使用rman或者cp命令备份控制文件和system表空间文件,cp命令备份redo,dd命令备份文件头,来完成asm情况下数据库异常恢复前备份

控制文件备份
11.2及其以后版本使用asmcmd cp命令处理

select 'asmcmd cp '||name||' &&backup_dir/' from v$datafile where ts#=0
union all
select 'asmcmd cp '||name||' &&backup_dir/crontrofile_'||rownum||'.ctl' from v$controlfile
union all
select 'asmcmd cp '||member||' &&backup_dir/'||thread#||'_'||a.group#||'_'||sequence#||'_'||substr(member,
instr(member,'/',-1)+1)  FROM v$log a, v$logfile b WHERE a.group# = B.GROUP#;

其他版本使用rman命令处理

--rman备份控制文件(/tmp目录自己修改)
copy current controlfile to '/tmp/ctl.ctl';
--rman备份system表空间
select 'copy datafile '||file#||' to ''&backup_dir/system_'||file#||'.dbf'';'
from v$datafile where ts#=0;
--redo无法直接备份

set pages 1000
select 'dd if='||path||' of=&asmbackup_dir/'||group_number||'_'||disk_number||'.asm bs=1048576

select 'dd of='||path||' if=&asmbackup_dir/'||group_number||'_'||disk_number||'.asm bs=1048576

asmlib需要注意把ORCL:替换为/dev/oracleasm/disks/对应目录.

Oracle异常恢复前备份保护现场建议—FileSystem环境

标题：Oracle异常恢复前备份保护现场建议—FileSystem环境

无论是在各种会议上,还是在朋友/网友私下请教Oracle数据库恢复的问题之时,我都强调,如果你没有十足的把握,请你对您的现场进行备份,确保别对现场进行二次损坏。你不能恢复数据库,但绝对不能再次破坏数据库,给二次恢复增加难度.这里对恢复前备份提供一些指导思想和简单脚本,希望对大家有帮助.

哪些文件需要备份
熟悉数据库恢复的朋友可能都情况,Oracle在异常恢复的过程中主要修改的是system表空间里面数据,其他数据文件,redo数据,控制文件(当然由于redo,undo导致其他数据文件内部的block也可能发生改变)。在备份时间,备份空间允许的情况下,是对这些文件全部备份为好

完整备份文件

set lines 150
set pages 10000
select name from v$datafile
union all
select name from v$controlfile
union all
select member from v$logfile;

有些情况下:比如如果全部备份时间过长,备份空间不足等情况下,我们该如何备份,尽量减少因为异常恢复导致对原环境的损坏.备份最核心的system表空间,数据文件头,redo file,control file等数据,由于这个不是简单的拷贝操作,因此在生成备份语句同时,也生成还原语句,切不可生成了备份语句后,无恢复语句,导致后面还原故障现场难度增大.

无法全备情况下linux/unix数据库恢复前备份

set lines 150
set pages 10000
select 'dd if='||name||' of=&&back_dir/'||ts#||'_'||file#||'.dbf bs=1048576 count=10'

instr(member,'/',-1)+1)  FROM v$log a, v$logfile b WHERE a.group# = B.GROUP#;

无法全备情况下linux/unix使用备份还原

set lines 150

select 'dd of='||name||' if=&&back_dir/'||ts#||'_'||file#||'.dbf bs=1048576 count=10 conv=notrunc'

instr(member,'/',-1)+1)    FROM v$log a, v$logfile b WHERE a.group# = B.GROUP#;

由于win路径斜杠不一样(/和\的区别),因此在无法全备情况下win备份语句

set lines 150
set pages 10000
select 'dd if='||name||' of=&&back_dir\'||ts#||'_'||file#||'.dbf bs=1048576 count=10'
from v$datafile where ts#<>0
union all
select 'dd if='||name||' of=&&back_dir\'||ts#||'_'||file#||'.dbf' from v$datafile where ts#=0
union all
select 'dd if='||name||' of=&&back_dir\control0'||rownum||'.ctl' from v$controlfile
union all
select 'dd if='||member||' of=&&back_dir\'||thread#||'_'||a.group#||'_'||sequence#||'_'||substr(member,
instr(member,'\',-1)+1)   FROM v$log a, v$logfile b WHERE a.group# = B.GROUP#;

在无法全备情况下win还原语句

set lines 150
set pages 1000
select 'dd of='||name||' if=&&back_dir\'||ts#||'_'||file#||'.dbf bs=1048576 count=10 conv=notrunc'

oid$=:12,spare1=:13, spare2=:14 where owner#=:1 and name=:2 and namespace=:3 and
remoteowner is null and linkname is null and subname is null

这里可以的出来由于obj$中的dataobj#为87422,而i_obj4中的dataobj#为87420,因此两者不一致。
另外通过相关trace发现,在创建表操作中会调用update obj$的一个递归操作,而该操作会更新dataobj#,但是由于该值在表和index中不匹配,因此出现ORA-08102导致创建表不成功

主要体现在进行了不完全恢复,而且应该是对redo进行了重命名或者redo头损坏锁引起的一系列提示

通过一些列方法(bbed,隐含参数等)调整数据库scn,强制启动数据库,报如下错误

SELECT NULL FROM PROPS$ WHERE NAME='BOOTSTRAP_UPGRADE_ERROR'

这里可以发现是数据库在启动的过程中需要执行SELECT NULL FROM PROPS$ WHERE NAME=’BOOTSTRAP_UPGRADE_ERROR’语句，而该语句递归调用了select obj#,type#,ctime,mtime,stime, status, dataobj#, flags, oid$, spare1, spare2 from obj$ where owner#=:1 and name=:2 and namespace=:3 and remoteowner is null and linkname is null and subname is null 语句。既然这样通过一些方法避免数据库启动之时查询SELECT NULL FROM PROPS$ WHERE NAME=’BOOTSTRAP_UPGRADE_ERROR’语句，果然数据库启动成功。

知识点补充
ORA-600 [4502] [a]

Arg [a] ITL entry with a lock count
Meaning: During ITL cleanout we clear all row locks but the ITL entry
	 still thinks there is an uncleared lock. Ie: ITL has a locked
	 row but there are no locked rows in the block

大体意思是数据库发现undo 的itl已经被清除，但是block中的itl依然存在，从而出现ORA-600[4502],引起该问题除bug外主要原因是坏块

ORA-600 [2037] [a] [b] {c} [d] [e] [f] [g]

Arg [a] Relative Data Block Address (RDBA) that the redo vector is for
Arg [b] The Block format
Arg {c} RDBA in the block itself
Arg [d] The block type
Arg [e] The sequence number
Arg [f] Flags, if set
Arg [g] The return value from the block head/tail checker.
DESCRIPTION:
  During recovery we are examining a block to ensure that it is not
  corrupt prior to applying any change vectors.
  The block has failed this check and this exception is raised

大体意思是在恢复过程中，正在检查的块，以确保它在应用任何变化向量之前不损坏。如果检查失败排除该异常ORA-600[2037],引起该问题除bug外主要原因是坏块

ORA-600 [kcbzpbuf_1],[a],[b]

Arg [a] Corruption reason
Arg [b] Calculate checksum flag
Corruption reason:
#define KCBH_GOOD    0                                     /* block is valid */
#define KCBH_ZERO    1             /* block header was entirely zero on disk */
#define KCBH_BROKEN  2      /* corruption could be from a partial disk write */
#define KCBH_CHKVAL  3               /* The check value for the block failed */
#define KCBH_CORRUPT 4     /* this is the wrong block or is not a data block */
#define KCBH_ZERONG  5               /* all zero block and it is not allowed */
Calculate checksum flag:
The possible values are 1 (Generate Checksum - db_block_checksum is enabled - default value)
                        0 (do not generate checksum - db_block_checksum=false)

kcbzpbuf_1是该错误的源码函数

ORA-600 [17182] [a] [b] {c} [d] [e]

DESCRIPTION:
  Oracle has detected that the magic number in a memory chunk header has been overwritten.
  This is a heap (in memory) corruption and there is no underlying data corruption.
  The error may occur in the one of the process specific heaps
  (the Call heap, PGA heap, or session heap) or in the shared heap (SGA).

ORACLE 发现在内存中重要的块头被重新,但是没有基础数据损坏,大部分和数据块或者内存损坏有关系.

ORA-600 [4552] [a] [b] {c} [d] [e]

DESCRIPTION:
  This assertion is raised because we are trying to unlock the rows in a
  block, but receive an incorrect block type.
  The second argument is the block type received.

ORACLE尝试对某行进行解锁但是接收到了不正确的数据块类型,Arg [b]是接收到的数据块类型

ORA-600 [2662] [a] [b] {c} [d] [e]

DESCRIPTION:
  A data block SCN is ahead of the current SCN.
  The ORA-600 [2662] occurs when an SCN is compared to the dependent SCN
  stored in a UGA variable.
  If the SCN is less than the dependent SCN then we signal the ORA-600 [2662]
  internal error.
ARGUMENTS:
  Arg [a]  Current SCN WRAP
  Arg [b]  Current SCN BASE
  Arg {c}  dependent SCN WRAP
  Arg [d]  dependent SCN BASE
  Arg [e]  Where present this is the DBA where the dependent SCN came from.

主要的含义就是oracle文件头scn比某个block dependent scn小从而出现该问题

通过这里可以知道数据库在启动的过程中由于无法访问access$表从而出现ORA-00942错误,又是由于该sql是数据库内部调用因为出现ORA-00604错误.
出现该错误的原因是由于:BUG:12733463 – ORA-704, ORA-604 AND ORA-942 ON TABLE ACCESS$ DURING STARTUP
官方提供方法

1. Shutdown (abort) the instance and clean up any OS structures used by the instance.

2. Retry the startup.
3. If the error persists try and recover the database or recover from a backup.

根据当前数据库恢复检查脚本(Oracle Database Recovery Check)收集的信息,数据库的是非归档状态,而且redo已经覆盖,数据库datafile 5 无法直接online.遇到这样情况,可以使用bbed修改文件头scn实现online(使用bbed让rac中的sysaux数据文件online),也可以通过使用_allow_resetlogs_corruption等隐含参数实现online.本恢复案例中有180个数据文件,160个offline,然后open数据库,所以大量数据文件无法正常online,bbed工作量太大.在恢复过程中不幸遇到ORA-01248

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
