导入

impdp test/test directory=DATABASE dumpfile=test.DMP schemas=test full=y logfile=import.log

imp test/test file=D:\ytzz\copy\test.DMP TABLESPACES=test

第三步、SQL>shutdown normal

      提示:数据库已经关闭       已经卸载数据库       ORACLE 例程已经关闭

第四步、SQL>startup mount

第五步、SQL>alter database open;

shutdown immediate

startup 

删除表空间文件出错

第1 行出现错误: ORA-01157: 无法标识/锁定数据文件19 - 请参阅DBWR 跟踪文件

ORA-01110: 数据文件19: ‘‘‘‘C:\oracle\oradata\oradb\FYGL.ORA‘‘

这个提示文件部分根据每个人不同情况有点差别。

继续输入 第六步、SQL>alter database datafile 19 offline drop;    --- 19对应报错的数据文件19

第七步、重复使用第五第六步,直到出现“数据库已更改”的提示,然后如下图,

继续输入shutdown normal,startup mount就OK啦
