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。

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.sh3. 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
