有关Dump 文件的命令有exp/imp 和 expdp/impdp。 这四个命令之前都有整理过相关的文章。
Oracle EXP/IMP 说明
exp/imp 与 expdp/impdp 对比 及使用中的一些优化事项
Oracle expdp/impdp 使用示例
Oracle 10g Data Pump Expdp/Impdp 详解
Oracle expdp/impdp 从高版本 到 低版本 示例
（1）如果是导出导入（exp/imp）,那么是indexfile参数。
（2）如果是数据泵（expdp/impdp）,那么是sqlfile 参数。

（1） 该import 命令并没有真正的import data，而只是生成了我们对应用户下所有DDL的sql 语句。
（2） 对于表的DDL语句，用REM 进行了注释。
