dmp文件为oracle数据库的数据备份文件,执行oracle数据库导出dmp文件,相当于执行数据库备份;执行导入dmp文件,相当于数据库还原。
在dos控制台下执行如下指令:
su -oracle
exp iflashbuy/password@width246 file=iflashbuy20140121.dmp owner=iflashbuy246
其中:
user //导出数据库表空间的用户名
password //对应的密码
orcl //数据库服务名(SID)
file //导出的dmp文件存放路径
执行过程中,控制台输出:

使用sys用户,以dba角色登录oracle数据库的em,创建表空间以及访问该表空间的用户名,并赋予用户如下角色:
1) connect
2) dba
3) EXP_FULL_DATABASE
4) IMP_FULL_DATABASE
5) RESOURCE
并赋予下列权限
系统控制台下输入:
imp user/psw@sid
其中:
user——数据库表空间的用户名
psw——数据库表空间的密码
sid——数据库服务名(sid)
执行后窗体提示输入dmp文件路径:
输入dmp文件路径后,后面提示选项使用默认值即可,具体界面如下:
1) imp user/psw@sid 执行导入指令;
2) EXPDAT.DMP > 提示输入dmp文件路径;
3) enter insert buffer size (min is 8192) 30720:提示最小设置为8192,建议设置30720,可以使用30720即可;
4) list contents of import file only,提示输入no。
5) 后面的4个输入,均使用默认值;
6) username:输入导出dmp文件的用户名,这样将导入该用户名关联的所有表对象;
7) if done:输入回车;
8) 执行导入…
注意:数据库中已经有的对象,执行导入的时候不覆盖,提示对象已经存在而执行失败的错误,输入如下:
不能通过ssh登录远程linux执行数据库恢复、备份,必须通过远程桌面,在linux系统的终端执行数据库恢复和备份。
