set CURDATE=%date:~0,4%%date:~5,2%%date:~8,2%
set hour=%time:~,2%
if "%time:~,1%"==" " set hour=0%time:~1,1%
set CURTIME=%hour%%time:~3,2%%time:~6,2%
REM 设置数据库名、用户名和密码  
set OWNER=ORCL
set USER=flzd
set PASSWORD=flzd
REM 创建备份用目录，目录结构为oraclebak/YYYYMMDD/  
if not exist "oraclebak"                     mkdir oraclebak
cd oraclebak
if not exist "%CURDATE%"          mkdir %CURDATE%
set FILENAME=%CURDATE%/%OWNER%_%CURDATE%%CURTIME%.DMP  
set EXPLOG=%CURDATE%/%OWNER%_%CURDATE%%CURTIME%_log.log  
REM 调用ORACLE的exp命令导出用户数据

exp %USER%/%PASSWORD%@%OWNER% file=%FILENAME% log=%EXPLOG%  owner=%USER% grants=n
