ORA-01113: file 10 needs media recovery
ORA-01110: data file 10: '/u01/app/PROD/disk1/test1.dbf'
ALERT日志中的相关信息:
Tue Nov 11 22:15:44 2014
ALTER DATABASE OPEN
ORA-1113 signalled during: ALTER DATABASE OPEN...
此时查看相关视图，10号数据文件--TEST1表空间的仍处于活动状态--:
SQL> select * from v$backup where STATUS='ACTIVE';
FILE# STATUS CHANGE# TIME
---------- ------------------ ---------- -------------------
10 ACTIVE 195848 2014/11/11 22:12:07 -->这里的时间是开始发出热备份命令BEGIN BACKUP的时间及当时SCN。
此时，可以使用两种命令来解决:
1.ALTER DATABASE RECOVER datafile 10;
2.ALTER TABLESPACE TEST1 END BACKUP;
#####################################################
-->如下是解决及OPEN数据库及验证数据文件状态;
SQL> ALTER DATABASE RECOVER datafile 10;
Database altered.
SQL> select * from v$backup where STATUS='ACTIVE';
no rows selected
SQL> alter database open;
Database altered.
