有客户反馈,断电之后数据库启动报ORA-00742和ORA-00312,无法正常open
ORA-742-ORA-312

我们远程上去尝试open库结果也报同样错误

    GROUP# STATUS

         1 INACTIVE
         3 CURRENT
         2 INACTIVE

因为recover已经成功,但是依旧报ORA-742错误,尝试查询scn相关信息

SQL> set pages 10000

SELECT status,
checkpoint_change#,
checkpoint_time,last_change#,
count(*) ROW_NUM
FROM v$datafile
GROUP BY status, checkpoint_change#, checkpoint_time,last_change#

SELECT status,

基于这样的情况,我们判断数据库直接open成功

SQL> recover database using backup controlfile;

后面比较不幸，数据库报ORA-600 4194错误导致数据库异常
