使用RMAN和控制文件备份删除归档日志的SHELL脚本--RED HAT 5 LINUX 64

在ORACLE用户下的定时器设置

[oracle@SHARKDB dbscripts]$ crontab -l
# minute hour day month week
15 1 * * 0 sh /home/oracle/dbscripts/backup_full.sh
05 3 * * * sh /home/oracle/dbscripts/del_arc.sh

全备脚本先配置保留时间窗口,配置备份目录和格式,然后交叉检查所有备份集.

删除无效备份集,删除过期对象,进行全备份并压缩..

[oracle@SHARKDB dbscripts]$ cat backup_full.sh

#!/bin/kshsource ~/.bash_profileecho "------------------Start------------------";date#backup start$ORACLE_HOME/bin/rman log=/home/oracle/dbscripts/logs/rman_full_backup.log << EOFconnect target /run{CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 2 DAYS;CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   '/arch/full_%d_%s_%T_%t.bak';crosscheck backupset;delete noprompt expired backupset;delete noprompt obsoleted;backup full  AS COMPRESSED BACKUPSET DATABASE include current controlfile  plus archivelog;}exit;EOFecho "-------------------End-------------------";date

删除归档日志先检查归档日志把物理删除的信息从控制文件删除,然后执行物理删除 2天前的.

[oracle@SHARKDB dbscripts]$ cat del_arc.sh

#! /bin/bashsource ~/.bash_profileexec >> /home/oracle/dbscripts/logs/del_arch`date +%F_%H`.log$ORACLE_HOME/bin/rman target / <<EOFcrosscheck archivelog all;delete noprompt expired archivelog all;delete noprompt archivelog until time 'sysdate-2';exit;EOF

如果没有SO 彼此语句 -- source ~/.bash_profile 那么要在ROOT下执行定时器切换用户执行脚本

03 04 * * * su - oracle -c '/home/oracle/del_arc.sh'
