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/ksh
source ~/.bash_profile
echo "------------------Start------------------";date
#backup start
$ORACLE_HOME/bin/rman log=/home/oracle/dbscripts/logs/rman_full_backup.log connect 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;
EOF
echo "-------------------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/bash
source ~/.bash_profile
exec >> /home/oracle/dbscripts/logs/del_arch`date +%F_%H`.log
$ORACLE_HOME/bin/rman target / crosscheck 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'
