Oracle 11g丢失access$恢复方法
11.1.0.7版本也会出现access$表丢失导致数据库无法启动
总结主要两类:1. 由于某种bug导致access$表丢失的故障,另外一种是由于坏块导致数据库核心基表损坏引起,对于这个库进行分析

dbv 检查坏块

在数据库的恢复过程中遇到ORA-600 4000错误挺多的，但是在oracle 8i(8.1.7)中遇到此类问题，还是第一次，做个记忆，供参考：
数据库故障起因：因为存储异常，导致当前redo损坏，并_allow_resetlogs_corruption参数尝试打开数据库

数据库遭遇ORA-600 4000错误，数据库无法打开，分析对应trace日志

Current SQL statement for this session:

----- Call Stack Trace -----

这里可以看出来，是因为数据库在启动之时需要执行select ctime, mtime, stime from obj$ where obj# = :1语句，但是由于每种原因出现ORA-600 4000导致数据库无法正常启动，继续分析日志

263570122

此处比较明显,通过xid可以知道三号回滚段中对应一个事务出现问题：
1. 该block为file 1 bock 62，object_id为 18（obj$)上有一个事务
2. 该事务的scn为263,570,886>database scn(263570122)导致该故障发生
3. 当数据库访问到file 1 block 62的时候，发现有一个事务，而该事务的scn大于数据库scn，从而出现ORA-600[4000]
解决该问题有几种方法
1. 修改block 62，人工提交该事务
2. 修改数据库scn，让数据库scn大于itl scn
解决block 62 事务问题后出现如下错误

该错误的原因是因为数据库在启动的过程中,会事先利用上次数据库运行过程中system undo segment header指向的block,而该block异常,所以出现该错误,使用bbed/dul之类的工具清除掉undo seg header 指向block指针,然后数据库启动会重新分配一个block,从而实现数据库正常启动.

undo异常恢复处理思路
除了极少数undo坏块,undo文件丢失外，大部分undo异常是因为redo未被正常进行前滚，从而导致undo回滚异常数据库无法open，解决此类问题，需要结合一般需要结合redo异常处理技巧在其中，一般undo异常处理思路
1.切换undo_management= MANUAL尝试启动数据库，如果不成功进入2
2.设置10513 等event尝试启动数据库，如果不成功进入3
3.使用_offline_rollback_segments/_corrupted_rollback_segments屏蔽回滚段
4.如果依然不能open数据库,考虑使用bbed工具提交事务，修改回滚段状态等操作
5.如果依然还不能open数据库，考虑使用dul

redo是oracle数据库比较核心文件,当redo异常之后,数据库无法正常启动,而且有丢失数据的风险,强烈建议条件允许redo多路镜像.redo文件异常的故障可以说是千奇百怪,但是总体上可以分为几类:

在这样的情况下,数据库异常关闭,current/active redo异常,通过使用隐含参数可能可以侥幸的恢复数据库,但是也可能导致数据丢失.这里因为是模拟情况,无业务所以在很多较为繁忙的业务系统中,使用隐含参数resetlogs过程中可能还会遇到如下很多常见的错误,进一步增加了恢复难度

current/active redo异常后附带其他错误

ksedmp: internal or fatal error
ORA-00600: internal error code, arguments: [4000], [83], [], [], [], [], [], []
Current SQL statement for this session:
select ctime, mtime, stime from obj$ where obj# = :1
--确定是obj$对象异常,通过某种手段找到obj$的objid和dataobjid均为16，对应16进制为12
Block header dump:  0x0040007a
 Object id on Block? Y
 seg/obj: 0x12  csc: 0xc1e.a329e76f  itc: 1  flg: -  typ: 1 - DATA
     fsl: 0  fnx: 0x0 ver: 0x01

这里比较明显obj$对象在rdba为0040007a的block上,scn为0c1e.a329e76f(13325725984623)且未提交的事务,这样的现象就决定了处理的特殊性(不是因为块延迟清理导致访问undo现象,该现象直接推进scn解决,而该情况不行)

数据文件头scn

SQL> SELECT DISTINCT CHECKPOINT# FROM V$DATAFILE_HEADER;
    CHECKPOINT_CHANGE#
-------------------------
           13324676536960

bbed查看文件头scn

   struct kcvfhckp, 160 bytes               @484
      struct kcvcpscn, 8 bytes              @484
         ub4 kscnbas                        @484      0x649c9a80
         ub2 kscnwrp                        @488      0x0c1e

这里看到的文件头scn也是为13324676536960(0c1e.649c9a80)和sql查询结果一致,也就是说数据库中的obj$的某个对象含有事务,且scn大于文件头scn(因为当前redo丢失,无法前滚,所以出现该情况),当数据库访问obj$的时候,为了事务的一致性,就需要访问undo(这里提示为83 回滚段),而undo异常,所以smon进程回滚失败,数据库无法正常启动

使用bbed提交事务

数据库在open过程中遇到大量ORA-00600[2662],这个是因为数据库中文件头的scn小于访问的数据块scn导致该问题,解决方法推荐scn,如果数据库的scn本身就很大(和时间理论scn较接近),推进过程中可能遇到如下错误,这个时候就需要选择合适的方法/合适的值来推进scn

后面的工作因为没有redo前滚,而且该库故障时有大量事务在跑,现在无法前滚,导致大量的undo回滚段异常,index和data不一致等故障,需要做的就是屏蔽undo seg,重建undo,重建库

根据这个错误提示ktbdchk–>bad dscn,猜测ktbdchk是header scn中的ktbdchk,查找1020770e发现是itl comomit scn,通过bbed查看

   ub2 kscnwrp                              @488      0x0000

通过这里可以知道ORA-00600[ktbdchk1: bad dscn]是因为itl comomit scn远大于datafile header scn,从而oracle认为datafile header scn是错误的,从而提示ktbdchk1: bad dscn.尝试bbed修改itl comomit scn

对于数据库恢复感兴趣的人,一定对于ORA-600[4000]这个著名的错误记忆犹新,这里通过试验重现ORA-600[4000]
查询数据库obj$.con$记录

bbed修改数据块
根据催华的研究,当OBJ$中部分数据块中的csc和itl的scn都大于header scn的时候,数据库启动就会报ORA-600[4000]
