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 。
