oracle11g自动备份.doc

一、以exp命令备份 1.首先做个批处理脚本:backup.bat 脚本内容如下 echo off set curdate=%date:0,4%date:5,2%date:8,2% set backuppath=D:backup md %backuppath% exp scott/tiger127.0.0.1/orcl file=%backuppath%curdate%.dmp owner(scott) log=%backuppath%curdate%.log forfiles /p D:backup /s /m *.dmp /d -30 /c cmd /c del file 说明：在备份之前先在D盘建个backup文件夹. 2.以Windows中的计划任务程序来触发这个备份脚本（以Win7为例）(1)完成配置，这个自动备份脚本会在每天10:43的时候执行，将数据备份到D:backup文件夹下 格式为:20151212.dmp2.导入dmp文件的命令spool log.txt;drop user scott cascade;drop tablespace SCOTT including contents and datafiles;create tablespace SCOTT logging datafile D:orclSCOTT .dbfsize 50m autoextend on next 50m maxsize 20480m extent management local;create user scott identified by tiger default tablespace SCOTT;grant connect,resource to scott;grant dba to scott;spool off;exit;在dos窗口输入命名导入数据文件imp scott/tigerORCL file=20151212.dmp full=Y二、以expdp命名备份脚本如下create directorymydmpas D:backup -directory指定导出到本地目录-授权给操作用户这个mydmp目录的权限grant read, write on directorymydmpto scott-需要超级管理员的账号 sysdba-查看一下是否存在该目录select * from dba_directories;执行脚本如下echo offrem set backupfile=%date:0,4%date:5,2%date:8,2%.dmprem set logfile=%date:0,4%date:5,2%date:8,2%.logrem delete 30days filesforfiles /p D:backup /d -30 /c cmd /cecho deleting file . & del /f pathcd D:backuprem backup schemasset backupfile=%date:0,4%date:5,2%date:8,2%.dmpset logfile=%date:0,4%date:5,2%date:8,2%.logexpdp scott/tiger directory=mydmp dumpfile=%backupfile% logfile=%logfile% schemas=scott parallel=4用expdp导出的必须要用impdp命令导入impdp scott/ti
