标题：重建控制文件丢失undo异常恢复—ORA-600 25025模拟与恢复
作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]
在现实的情况中，有些人因为某种原因重建控制文件(丢失undo[有意或者无意])，然后又resetlogs库尝试恢复,这样的操作可能导致各种比较麻烦的恢复,这里模拟ORA-600[25025]异常恢复
模拟ORA-600[25025]错误

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
