概述

  1，源系统:10.2.0.4 rhel5 for x86

        目标系统：10.2.0.4 rhel5 for x86

  2,源与目标系统的字符集及国家字符集一致，皆为utf8与alutf16

  3,源系统：exp 用户及表空间为pdtong及tongyihua

     目标系统：imp用户及表空间为pd及pd

实验：如果直接imp导入

imp userid=system/system fromuser=pd touser=pd file=20100715_export_pd.dmp log=new_new_import.log

报错如下：

-bash-3.1$ more 1141_imp.log

   很明显，导出与导入的表空间不一致，最终imp可以成功，但会报一堆的错，当然错误基本是一样的，表空间不存在及表视图不一存在.

  有 两种方法：

1，在imp前，直接用vi批量替换dmp文件的表空间名字为要导入的表空间名字

vi 20100715_export_pd.dmp

:%s/TONGYIHUA/PD/g

:wq或:x --保存退出

执行导入imp userid=system/system fromuser=pd touser=pd file=20100715_export_pd.dmp log=new_new_import.log

2,在imp前，在目标数据库创建与dmp文件一致的表空间

执行导入imp userid=system/system fromuser=pd touser=pd file=20100715_export_pd.dmp log=new_new_import.log

具体选用哪种，视当时的应用情景
