exp/imp中如何实现远程导出操作

这篇文章将为大家详细讲解有关exp/imp中如何实现远程导出操作，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

实验：
源库：:192.168.56.20  hostname:slient
目标库：:192.168.56.12 hostname:wang

说明：
tns:20，为对源库的连接字符串、owner指的是源库的schema,生成的dmp文件是在目标库

[oracle@wang dpdump]$ exp system/oracle@20 owner=scott file=partition.dmp log=partition.log

===补充=========

问题的现象：

EXP-00026: conflicting modes specified
EXP-00000: Export terminated unsuccessfully  

备份文件会生成 但是没有内容。

这个问题主要是 exp的时候 里面参数发生了冲突。

   比较常见的： 

1.同时指定了 owner  和 tables

2.同时指定了 FULL 和tables

3.同时指定了多个owner和full

owner 表示导出整个用户或者多个用户  而tables表示只导出其中的表 。

要么只导出其中的表  要么导出整个用户。不然就会冲突了、
