oracle自动备份并打包成压缩文件的脚步------绝对非常实用，window中添加定时任务就可自动备份了

@echo 开始备份….

@echo 本程序使用zip压缩，备份后的文件可使用rar或者zip解压。

set instanse=orcl

set username=user

set password=password

set extname=rar

set year=%date:~0,4%

set month=%date:~5,2%

set day=%date:~8,2%

set mydate=%year%-%month%-%day%

set spath=e:\backup\

mkdir "%spath%"

set filename=e:\backup\%username%%mydate%

@echo %filename%

exp %username%/%password%@%instanse% file=%filename%.dmp owner=%username% log=%filename%.log

C:\WinRAR\rar.exe a %filename%.%extname% %filename%.dmp %filename%.log

del %filename%.dmp

del %filename%.log

@echo 备份完毕！

@echo 备份文件为：%filename%.%extname%

@echo 执行sql….

@echo off

echo OK!

把上面脚步写在批处理文件（bak_oracle.bat）文件中，就搞定了
