    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#
ORDER BY status, checkpoint_change#, checkpoint_time;

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;
ORA-00279: change 1279351848 generated at 03/26/2024 00:05:45 needed for thread 1

Specify log: {<RET>=suggested | filename | AUTO | CANCEL}
/oradata/shrdh/redo03.log

SQL> alter database open resetlogs;

Database altered.

后面比较不幸，数据库报ORA-600 4194错误导致数据库异常
