ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr]问题处理

服务器断电，异常关机后，重启报错ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr]

数据库运行环境是Linux上运行的ORACLE11G

--尝试启动数据库实例，报错如下：

SQL> startup
ORACLE instance started.

ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr], [1],
[89], [32294], [32511], [], [], [], [], [], [], []

--此时数据库启动到mount状态，尝试以resetlogs方式open数据库，也无法打开
SQL> select open_mode from v$database;

OPEN_MODE
--------------------
MOUNTED

SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery

--尝试recover后，打开数据库，仍然报相同错误
SQL> recover database;
Media recovery complete.
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [kcratr_nab_less_than_odr], [1],
[89], [32294], [32511], [], [], [], [], [], [], []

查询告警日志alter和trace文件,对照上网查询错误，获取报错原因：
由于服务器异常短电，导致LGWR写联机日志文件时失败，下次重新启动数据库时，需要做实例级恢复，而又无法从联机日志文件里获取到这些redo信息，因为上次断电时，写日志失败了。

--查看当前日志文件情况，从以下查询结果可以看到当前日志组为89，
SQL> select group#,sequence#,status,first_time,next_change# from v$log;

GROUP# SEQUENCE# STATUS FIRST_TIM NEXT_CHANGE#

--恢复数据库，指定redo02.log日志
SQL> recover database until cancel using backup controlfile;

--恢复完成后，再次可以正常打开数据库，重启数据库正常。
