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')
