本次上传的脚本有很多可以改进的地方！这也是本人第一次在网上发帖，SH写的不好的地方
不要见笑！！！！！！本SH以在SCO OPENSERVER 505（ORACLE 7.3.2）和IBM RS6000 AIX 4.3（ORACLE 8.1.6）调试通过！！如果要转载，请加上出处！！！谢谢！！！详细功能见脚本文件SH的批注！！！如果能要加上自动执行的功能请使用crontab配置即可！！！！
第一个文件：INIT.TXT这是脚本INI初始化文件：

#1:自动检查是否能连上Oracle!
#2:通过初始化文本来解析各种需要的参数!
#3:自动完全到出ORACLE数据库(每天)!,以后将增加相关的增量备份等!
#4:自动删除配置文件中规定的前X天的备份文件!
#5:自动将到出文件打包并转存到其他的备份机器上!
#6:自动记录程序执行过程中的所有日期信息!
