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 timeimport 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_node2def backup_clear(): cls_command1 = '/usr/bin/find %s -mtime +1 -name "*.dmp" -exec rm -rf {} \;' % data_path cls_command2 = '/usr/bin/find %s -mtime +1 -name "*.log" -exec rm -rf {} \;' % data_path if os.system(cls_command1) == 0 and os.system(cls_command2) == 0: print "\n\033[1;32;40m%s\033[0m" % cls_node1 else: print "\n\033[1;31;40m%s\033[0m" % cls_node2 print "%s" % cls_command1 print "%s\n" % cls_command2def main(): oracle_exp() backup_clear()if __name__ == "__main__": main()
执行结果:
