分析两个主机和Oracle数据库巡检脚本，值得收藏
mhr18 2024-09-20 20:57 37 浏览 0 评论
概述
分享一个之前我用来巡检主机和Oracle的脚本，不过输出结果不是很美观，内容还是可以的...
主机巡检脚本：OSWatcher.sh
ps:这里的第10项，普通用户检查/var/log/messages很可能没有读权限，如有需要巡检此系统日志，建议切换root用户执行此脚本。

脚本使用
1、创建目录并授权
# mkdir -p /home/oracle/scripts # chown -R oracle.oinstall /home/oracle/scripts/ # chmod -R 755 /home/oracle/scripts/
2、两脚本都用oracle用户执行
切换到oracle用户，执行两个脚本：
$./OSWatcher.sh $./ORAWatcher.sh
3、查看巡检内容
注意：ORAWatcher.sh脚本中数据库的默认连接串是：system/system，如果system密码不是这个，可以这样执行：./ORAWatcher.sh system/password
虽然后面都是用工具巡检了，但是这个脚本还是有可借鉴之处的。后面会分享更多devops和DBA方面的内容，感兴趣的朋友可以关注一下~
