指令碼如下：
[oracle@ycr python]$ more dump.py 
#/usr/bin/python
#coding:utf8

import sys
import os
import time

nowt=time.strftime('%Y%m%d%H',time.localtime())
excmd='expdp %s/%s@%s directory=YCRDUMP dumpfile=ycrdump%s.dmp' % (sys.argv[1],sys.argv[2],sys.argv[3],nowt)
result=os.system(excmd)

測試結果如下：

[oracle@ycr python]$ python dump.py test oracle ycr2              ---------三個引數分別為，使用者名稱test，密碼oracle和連線字串ycr2
