模拟基表事务未提交数据库crash,undo丢失恢复异常恢复

发表于 2013 年 8 月 31 日 由 惜分飞

对于基表特别是bootstrap$中的表,如果进行了dml操作,但是没有提交,这个时候数据库crash,而且undo异常.对于类似的场景,都是很多数据库恢复的人都有畏惧,因为_corrupted_rollback_segments参数不能起作用.本实验dml修改seq$表,最终却引起了undo$和I_UNDO1异常(他们都在bootstrap$中)
模拟seq$表事务未提交

通过观察每次的10046文件,发现总是在查询select /*+ rule */ name,file#, block#,status$,user#,undosqn,xactsqn, scnbas,scnwrp,DECODE(inst#,0,NULL,inst#),ts#,spare1 from undo$ where us#=:1并且总是us#=27号回滚段上过不去,通过使用bbed或者dul修改数据文件,让数据库启动时候不再扫描27号回滚段(主要是修改undo$.status$=1,block位置可以通过10046确定,也可以通过odu来确定,亦或者找个相同版本的库查看)

继续open数据库

直接修改基表,bbed/dul修改数据文件等操作都是危险级别非常高的操作,而且oracle not support,在没有十足把握之前,一定不要在生产环境中执行,如果数据库挂了需要类似方法恢复,也请一定保留现场,如果你搞不定能够还原现场
部分操作可以参考:通过bbed修改回滚段状态解决ORA-00704故障

重建控制文件丢失undo异常恢复—ORA-01173模拟与恢复

发表于 2013 年 8 月 30 日 由 惜分飞

数据库异常关闭，使用resetlogs方式重建控制文件，不包含undo表空间相关数据库，然后尝试resetlogs打开数据库，非常容易出现ORA-01173: data dictionary indicates missing data file from system tablespace之类的错误，本文通过模拟该错误，并简单提供解决方法

解决方案
解决方案设置相关异常回滚段,然后屏蔽掉，数据库即可正常起来

--参数文件修改(使用event或者工具，系统命令等)
undo_management='manual'
_corrupted_rollback_segments

--重启数据库使得_corrupted_rollback_segments生效
shutdown immediate;
startup 

--尝试open数据库
recover database;
alter database open;

--新建undo
create undo tablespace undo_new datafile '' size 100m autoextend on next 10m maxsize 30G;

--删除老undo
drop tablespace old_undo

--修改参数
shutdonw immediate
undo_management='auto'
undo_tablespace='unod_new'

--启动数据库
startup

--逻辑导出数据，导入新库

MOS中有类似描述ORA-600 [25025] [25] While Opening the Clone Database in Resetlog Mode (Doc ID 603100.1),该解决方案是重建控制文件增加所有数据文件，在本次测试中，我就是人为除掉了undo，模拟undo丢失[其实数据库已经resetlogs过了，就算加入undo重建控制文件也不会成功(人工修改undo文件头除外)]，又做了不正确的重建控制文件操作的故障，我提供解决方案如下

解决办法

--参数文件修改
undo_management='manual'

--尝试open数据库
recover database;
alter database open;

--新建undo
create undo tablespace undo_new datafile '' size 100m autoextend on next 10m maxsize 30G;

--屏蔽需要恢复回滚段
select tablespace_name,segment_name,status from dba_rollback_segs;
_corrupted_rollback_segments

--重启数据库使得_corrupted_rollback_segments生效
shutdown immediate;
startup 

--删除老undo
drop tablespace old_undo

--修改参数
shutdonw immediate
undo_management='auto'
undo_tablespace='unod_new'

--启动数据库
startup

--导出数据，导入新库
