ora-01157问题怎么解决？
环境：redhat 9 + oracle 817
问题：昨天突然掉电之后数据库启动之后就提示这个错误。数据是非归档模式，而且这个数据文件还有用。怎么恢复。

数据库是否归档模式？
在mount状态：
归档的话：
sql>alter database datafile 'i:/oradata/examora/test01.dbf' offline;
非归档的话：
sql>alter database datafile 'i:/oradata/examora/test01.dbf' offline drop;
然后在
sql>alter database open;
[[email protected] root]$ cd /home/oracle
[[email protected] oracle]$ ll *.dbf
