Oracle Recovery Tools快速恢复断电引起的无法正常启动数据库(ORA-01555,MISSING000等问题）

发表于 2023 年 4 月 17 日 由 惜分飞

由于异常断电,数据库启动报错ORA-01113和ORA-01110，ORA-00322和ORA-00312以及ORA-00314和ORA-00312错误

然后尝试一系列操作,比如重建ctl,再次拉库等等,均未绕过该错误.对于ORA-704 ORA-01555错误,使用开发的小工具Oracle Recovery Tools可以一键式解决,参考处理过的类似文章:Oracle Recovery Tools恢复—ORA-00704 ORA-01555故障,不过最近发布的版本中增加了直接修改内存SCN功能,可以更加快速的解决给问题

修复之后,数据库open成功

SQL> alter database open;

数据库已更改。

SQL> shutdown immediate;
数据库已经关闭。
已经卸载数据库。
ORACLE 例程已经关闭。
SQL> startup pfile='d:/pfile.txt' mount;
ORACLE 例程已经启动。

已选择2行。

很不幸技术在尝试重建ctl的恢复的过程中遗漏了两个数据库文件,通过Oracle Recovery Tools再次进行恢复
20230417230141

在sqlplus中恢复这两个文件成功

SQL> alter database rename file 'D:\APP\ADMINISTRATOR\PRODUCT\11.2.0\DBHOME_1\DATABASE\MISSING00012' 
   2 to 'D:\oradata\XIFENFEI_04.DBF';

SQL> alter database rename file 'D:\APP\ADMINISTRATOR\PRODUCT\11.2.0\DBHOME_1\DATABASE\MISSING00013' 
   2 to 'D:\oradata\XIFENFEI_5.DBF';

数据库已更改。


SQL> alter database datafile 12,13 online;

数据库已更改。

SQL>
SQL>
SQL> alter database open ;
alter database open 
*
第 1 行出现错误:
ORA-01113: 文件 12 需要介质恢复
ORA-01110: 数据文件 12: 'D:\ORADATA\XIFENFEI_04.DBF'


SQL> recover datafile 12;
完成介质恢复。
SQL> recover datafile 13;
完成介质恢复。
SQL> alter database open;

数据库已更改。

至此数据库基本上恢复完成,剩余工作就是逻辑导出导入.
