ORA-600 kcratr_nab_less_than_odr和ORA-600 4194故障处理---惜分飞

客户一个11.2.0.1的库由于断电导致启动的时候报ORA-600 kcratr_nab_less_than_odr错误

类似的ORA-600 kcratr_nab_less_than_odr故障处理不少,但是应用redo完成之后,再open报错的不多:
ORA-600 kcratr_nab_less_than_odr故障解决
但是这个客户比较不幸,经过一系列尝试打开数据库,但是报ORA-600 4194错误

后续由于该undo异常报ORA-01595和ORA-600 4194等错误导致数据库crash

接手这个库之后,处理工作相对比较简单,直接对异常undo进行重建即可

Thu Aug 07 09:35:08 2025 create undo tablespace undotbs2 datafile 'D:\APP\xff\ORADATA\ORCL\undotbs02.dbf' size 128M autoextend on Completed: create undo tablespace undotbs2 datafile 'D:\APP\xff\ORADATA\ORCL\undotbs02.dbf' size 128M autoextend on Thu Aug 07 09:37:53 2025 drop tablespace UNDOTBS1 including contents and datafiles Deleted file D:\APP\xff\ORADATA\ORCL\UNDOTBS01.DBF Completed: drop tablespace UNDOTBS1 including contents and datafiles

然后数据库报大量的ORA-600 kdsgrp1错误

通过分析是由于index和表记录不匹配导致,对index进行重新rebuild完成本次修复任务.
