Linux系统中imp导入dmp文件

[oracle@ocm1 ~]$ ll

-rw-r--r-- 1 oracle oinstall 24576 Mar 27 15:26 COUNTRIES.dmp
drwxr-xr-x 2 oracle oinstall 4096 Mar 27 12:39 script
drwxr-xr-x 2 oracle oinstall 4096 Mar 19 14:51 temp
下面是导入：
[oracle@ocm1 ~]$ imp

Import file: expdat.dmp > /home/oracle/COUNTRIES.dmp

IMP-00010: not a valid export file, header failed verification
IMP-00000: Import terminated unsuccessfully
[oracle@ocm1 ~]$
头部验证失败是由于版本号不同所致，经试验可以通过如下方法进行修改：
可以看到头部信息－TEXPORT:V11.01.00，即为源数据库的版本号，将其修改为目的数据库的版本号，
如本机为10.02.01，再次进行导入操作，导入成功
[oracle@ocm1 ~]$ vi COUNTRIES.dmp --直接使用vi修改下头部的版本号即可
^C^CiEXPORT:V10.02.00--之前是EXPORT:V11.02.00

再次导入，成功：
