Python Oracle数据库备份脚本

学习Python，将shell备份脚本改成了Python脚本练手，Python Oracle备份脚本一例如下。

#!/usr/bin/env python 

# -*- coding: utf-8 -*-

import time

import os

#配置oracle环境变量参数

os.environ["NLS_LANG"] = "Simplified Chinese_china.ZHS16GBK"

os.environ['ORACLE_HOME'] = '/u01/app/oracle/product/10.2.0/db_1'

os.environ['PATH'] = "/u01/app/oracle/product/10.2.0/db_1/bin" + ":" + os.environ['PATH']

os.environ['ORACLE_SID'] = "orcl"

os.environ['LANG'] = "en_US"

#打印提示信息。

exp_node1 = "\n成功备份文件到目录...."

exp_node2 = "备份失败"

cls_node1 = "数据库备份数据清除成功,删除语句如下...."

cls_node2 = "数据库备份清除失败"

#配置导出的数据库信息

data_path = '/tmp/'

db_username = 'abc'

db_password = 'abc'

db_name = 'abc'

"""

print os.getenv('NLS_LANG')

print os.getenv('ORACLE_HOME')

print os.getenv('ORACLE_SID')

"""

def oracle_exp():

    exp_command = "exp %s/%s file=%s%s_%s-%s-%s_%s%s%s.dmp log=%s%s_%s-%s-%s_%s%s%s.log"  % (db_username,db_password,data_path,db_name,time.strftime('%Y'),time.strftime('%m'),time.strftime('%d'),time.strftime('%H'),time.strftime('%M'),time.strftime('%S'),data_path,db_name,time.strftime('%Y'),time.strftime('%m'),time.strftime('%d'),time.strftime('%H'),time.strftime('%M'),time.strftime('%S'))

    exp_note = "数据库备份执行语句...."

    print "\033[1;31;40m%s\033[0m" %  exp_note

    print "\033[1;31;40m%s\033[0m" %  exp_command

    if os.system(exp_command) == 0:

        print "\033[1;32;40m%s\033[0m" % exp_node1

    else:

        print "\033[1;31;40m%s\033[0m" % exp_node2

    print "%s" % cls_command1

    print "%s\n" % cls_command2

def main():

    oracle_exp()

    backup_clear()

if __name__ == "__main__":

    main()
