分享一例由于主库逻辑坏块导致dataguard容灾失效

发表于 2015 年 7 月 10 日 由 惜分飞

有朋友数据库配置了物理dataguard，但是由于触发了某种Oracle bug/或者其他原因导致block出现大量逻辑坏块，结果是主备库(主库启动后就crash,备库failover后也启动后就crash)都无法正常工作,请求给予技术支持。
数据库配置了物理dataguard，但是主库在进行了某些操作之后，主库直接crash.重启主库发现，数据库启动之后，稍后数据库继续CRASH

把datafile 67给offline之后，数据库open正常，也不再crash。这里比较明显，导致主库和被动都出现异常,主库直接crash，然后重启后，一会儿就crash；备库激活后，重启后一会儿也就crash；两个库现象相同。最后通过dbv定位到是由于某个文件出现大量逻辑坏块，导致数据库open之后，进行回滚之时crash.对于此类故障，可以通过屏蔽事务回滚，并且通过alert日志和trace文件定位到异常对象，可以删除异常对象可以暂时解决该问题。而导致数据库出现类似问题。
通过这个案例，可以的出来，由于oracle某种bug或者其他原因，导致block 逻辑损坏，而且这个损坏会传输到备库，导致备库也异常，oracle的备份，容灾不能全部依赖物理dataguard容灾。因此在条件允许情况下，建议增加物理备份和逻辑容灾（类似OGG)

通过bbed修改obj$中dataobj$重现I_OBJ4索引报ORA-08102错误

发表于 2015 年 3 月 14 日 由 惜分飞

在最近的数据库恢复中,经历了多次11.2库由于各种原因,数据库打开后,报ORA-8102错误,而且错误对象是OBJ$上的I_OBJ4这个index上,而且不能创建新表,周末开会闲着无事,进行了一个简单的模拟重现
数据库版本信息11.2.0.4

SQL> select * from v$version;

定位需要破坏的OBJ$上记录,为了使之和I_OBJ4中记录不一致,从而实现ORA-8102错误

这里我们知道i_obj4中的dataobj#最大值为87420对应的16进制记录为04 c3 09 4b 15

使用bbed破坏记录,修改dataobj#中的值,使得obj$.dataobj#和i_obj4中的dataobj#不匹配

朋友让我帮忙处理一个不能open的库,打开alert日志一看,傻眼了,里面是各种ORA-600的错误应有尽有,被折腾的够惨
故障后重启,无法启动主要表现在block坏块,引起的各种ORA-600等错误

进一步折腾,可以看出来undo已经被其offline,无法正常访问,导致系统报ORA-704和ORA-00376

通过Oracle数据库异常恢复检查脚本(Oracle Database Recovery Check)检测结果见附件(xifenfei_db_recover_20150304),这里可以知道undo 不知道怎么折腾的数据文件scn较大而且还offline,
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

根据经验,该错误怀疑是文件头scn不够大,块延迟清理导致,进一步增加scn尝试,最后依旧是ORA-00704/ORA-00604/ORA-01555错误

根据经验,在scn上做手脚估计难以解决给问题,对其启动过程做10046和errorstack分析发现

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
