linux rman 自動備份
在rmanscripts下面建 rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh 文件：
mkdir oradataback
--home/oracle/app/oradataback
chmod 775 oradataback
chown -R oracle:oinstall /home/oracle/app/oradataback
touch rmanlevel0.sh rmanlevel1.sh rmanlevel2.sh
赋权同上
2. vi 编辑3个文件： connect target /; 1级备份文件： delete noprompt obsolete; # 删除过期的备份 #说明：在oracle用户下手动运行脚本的命令：sh rmanlevel2.sh 3. 加自动运行任务： --查看添加的任务： crontab -l 4. 测试结果： --附加一个ftp.sh文件： #!/bin/sh #!/bin/sh ------全備 connect target /; run { #!/bin/sh ---累計 EOF run startrman.sh 說明每週三日全備其他執行歸檔備份 先調用執行oracle用戶的環境變量，已獲得執行環境 #!/bin/sh . /home/oracle/.bash_profile #------------------------------ ps -ef| grep dbw0_$ORACLE_SID | grep -v grep >> /dev/null #----------------------------- if if [$? -eq 0]:then 给脚本授予权限 我的腳本 ------累計

在root下设置，用vi编辑： #crontab -e
0 2 1 * * su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel0.sh //每月1日2：00运行 0级备份
0 2 * * 0 su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel1.sh //每周日2：00运行 1级备份
0 2 * * 1-6 su – oracle -c /home/oracle/app/oradataback/rmanscripts/rmanlevel2.sh //每周一周六2:00运行 2级增量备份
--crontab的格式：
minutes|hours|day of month|month|day of week|
--启动crond：
/sbin/service crond start //启动服务
/sbin/service crond stop //关闭服务
/sbin/service crond restart //重启服务
/sbin/service crond reload //重新载入配置
可以自动运行，能成功的备份数据。

[oracle@mzl backup]$ chmod +x archivelogbackup.sql
给脚本授予权限
[oracle@mzl backup]$ chmod +x startrman.sh
9 编写定时器crontab,定制每天1：30调用/u01/backup/startrman.sh脚本
[oracle@mzl ~]$ crontab -e
内容：
30 1 * * 0-6 /u01/backup/startrman.sh
查看crontab:
[oracle@mzl ~]$ crontab -l
30 1 * * 0-6 /u01/backup/startrman.sh
最后：测试日期可以用
[oracle@mzl ~]$ echo date=`date +%Y%m%d`
date=20080610
测试星期：
[oracle@mzl ~]$ echo week=`date +%w`
week=2
