重建控制文件丢失undo异常恢复 ORA-01173模拟与恢复

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
