一、处理步骤
1、使用终端登录上服务器查看磁盘使用状态 可以看出可用空间只有一百多MB了,所以拒绝连接了。 [rootrac1 ~]# su - grid

gridASM1:/home/grid$三、定时任务自动清归档日志 为了更好的改善使用体验我们可以使用shell脚本编写定时任务自动清除归档日志 1、编写删除脚本
mkdir /root/delOracleLog
mkdir /root/delOracleLog/log
cd /root/delOracleLog
chmod 777 /root/delOracleLog -R
vi del_ora_log.rman文件内容如下 crosscheck archivelog all;
delete noprompt expired archivelog all;
delete noprompt archivelog until time sysdate-20; #清理20天之前的日志
exit;2、编写shell脚本 vi /home/oracle/delOracleLog/del_oracle_log.sh
#! /bin/bash
dtdate %Y%m%d
rman target/ cmdfile/root/delOracleLog/del_ora_log.rman log/root/delOracleLog/log/del_ora_log_${dt}.log 214、测试脚本运行情况
[rootrac2 delOracleLog]# su - oracle -c /root/delOracleLog/del_oracle_log.sh
RMAN 2 3 4 [rootrac2 delOracleLog]# cat ./log/del_ora_log_20231124.log Recovery Manager: Release 11.2.0.4.0 - Production on Fri Nov 24 08:53:53 2023Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.connected to target database: ORCL (DBID1556520972)RMAN crosscheck archivelog all;
2 delete noprompt expired archivelog all;
3 delete noprompt archivelog until time sysdate-20; #清理20天之前日志
exit;
4
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID2852 instanceorcl2 device typeDISK
specification does not match any archived log in the repositoryRecovery Manager complete.
5、设置定时任务每周执行一次并测试运行效果
crontab -e 设置为每周五 9点25执行一次。【测试效果用实际情况建议夜间运行】
25 9 * * 5 su - oracle -c /root/delOracleLog/del_oracle_log.sh启动定时任务 service crond start 测试定时任务运行效果 [rootrac2 delOracleLog]# pwd
/root/delOracleLog
[rootrac2 delOracleLog]# ll ./log/
