ORA-00600 kcratr_nab_less_than_odr
早上发现Oracle数据库报如下错误：

查看数据库需要恢复，但是数据库异常断电，导致LGWR写到日志文件失败。这里 [kcratr_nab_less_than_odr], [1], [6], [15358], [15932]
需要恢复序列号为6的日志到15932个快，但是目前只能到15358
在mount状态查看当前日志：
SQL> select * from v$log;

进行恢复：

打开数据库发现scn又不一致，这里推进以下scn即可：
SQL> conn / as sysdba
Connected to an idle instance.
SQL>
SQL> startup mount;
ORACLE instance started.

哈哈，，终于打开数据库了。异常断电还是很坑爹的。
