You can let Export prompt you for parameters by entering the EXP
command followed by your username/password:

Example: EXP SCOTT/TIGER

Or, 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 table

USERID must be the first parameter on the command line.

exp help=y

1、EXP:

有三种主要的方式（完全、用户、表）

1、完全：

EXP SYSTEM/MANAGER BUFFER=64000 FILE=/data/full.dmp FULL=Y

如果要执行完全导出，必须具有特殊的权限

2、用户模式：

EXP SONIC/SONIC BUFFER=64000 FILE=/data/sonic.dmp OWNER=SONIC

这样用户SONIC的所有对象被输出到文件中。

3、表模式：

EXP SONIC/SONIC BUFFER=64000 FILE=/data/t_sonic.dmp OWNER=SONIC TABLES=(SONIC)

这样用户SONIC的表SONIC就被导出

2、IMP:

具有三种模式（完全、用户、表）

1、完全：

IMP SYSTEM/MANAGER BUFFER=64000 FILE=/data/full.dmp FULL=Y

2、用户模式：

IMP SONIC/SONIC BUFFER=64000 FILE=/data/sonic.dmp FROMUSER=SONIC TOUSER=SONIC

这样用户SONIC的所有对象被导入到文件中。必须指定FROMUSER、TOUSER参数，这样才能导入数据。

3、表模式：

EXP SONIC/SONIC BUFFER=64000 FILE=/data/t_sonic.dmp OWNER=SONIC TABLES=(SONIC)

这样用户SONIC的表SONIC就被导入。
