exp 用法参考如下：Export: Release 8.1.6.0.0 - Production on Wed Nov 6 11:45:38 2002(c) Copyright 1999 Oracle Corporation. All rights reserved.You can let Export prompt you for parameters by entering the EXP
command followed by your username/password: Example: EXP SCOTT/TIGEROr, you can control how Export runs by entering the EXP command followed
by various arguments. To specify parameters, you use keywords: Format: EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)
Example: EXP SCOTT/TIGER GRANTS=Y TABLES=(EMP,DEPT,MGR)
or TABLES=(T1:P1,T1:P2), if T1 is partitioned tableUSERID must be the first parameter on the command line.Keyword Description (Default) Keyword Description (Default)

FILESIZE maximum size of each dump file
QUERY select clause used to export a subset of a tableThe following keywords only apply to transportable tablespaces
TRANSPORT_TABLESPACE export transportable tablespace metadata (N)
TABLESPACES list of tablespaces to transportExport terminated successfully without warnings.

我的exp错了马?能不能够给我个解释,很多资料都是这样写的,而且就是表不能够导入!谢谢!
D:\>exp system/manager owner=(用户1,用户2,…,用户n) file=导出文件
（确定你的导出程序为exp.exe)
你可以试着用这两种方法导出
我想应该是你设的增量标识有些问题
也不是imp的问题，而是建立用户的问题，建用户的时候只有角色，没有系统权限，结帐了，全部都有分！ zero88(零点) 你给了我启发亚！
