如何分析两个主机和Oracle数据库巡检脚本

如何分析两个主机和Oracle数据库巡检脚本，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

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
