$ORACLE_HOME/bin/rman target / <crosscheck archivelog all;
delete noprompt expired archivelog all;
delete noprompt archivelog until time 'sysdate-14';
exit;
EOF

#说明:以上脚本删除14天以前所有归档日志,同时记录log

$ORACLE_HOME/bin/rman target / <等同于
$ORACLE_HOME/bin/rman <connect target sys/password@mydb

delete noprompt archivelog all completed before 'sysdate-14';
等同于
delete noprompt archivelog until time 'sysdate-14';

AIX下计划任务
以下为rman定时删除归档日志方法：
将附件中del_arch.sh文件上传至数据库服务器，oracle用户的可读取目录，例如/home/oracle。赋予可执行权限(chmod +x del_arch.sh)
在root用户下，crontab -e
20 20 * * 3 su - oracle -c '/home/oracle/del_arch.sh' 引号内为脚本位置。（代表每周三20：20执行脚本，删除日志）
