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 EXPcommand followed

by various arguments. To specify parameters, you use keywords:

Format: EXP KEYWORD=value or KEYWORD=(value1,value2,...,valueN)

Example: EXP SCOTT/TIGER IGNORE=Y TABLES=(EMP,DEPT) FULL=N

or TABLES=(T1:P1,T1:P2), if T1 is partitioned table

USERID must be the first parameter on the command line.
