公网IP:公网IP,也称为公共网络IP地址,是由互联网服务提供商(ISP)分配给网络设备的唯一标识。它允许设备在互联网上被直接访问和通信。每个公网IP地址在全球范围内都是唯一的,确保了通信的准确性和可靠性。公网IP通常用于需要对外提供服务的场景,如网站、服务器、在线游戏等。私网IP:私网IP,也称为私有网络IP...
与Public IP一样,Private IP称为私网IP或心跳IP,它也是网卡上的真实IP,每个节点在安装Oracle集群软件之前都需要事先配置Private IP。Private IP用于集群间多节点心跳同步和Cache Fusion等任务,在Oracle 12c中还需要担任Flex ASM的任务。当然,如果不设置Private IP而是由Public IP也可以去完成这些任务。但是,这样做只...

Yes, private IP addresses are traceable, but only by other devices on your local network. Each device connected to your local network has a private IP address, and each device’s private IP address can be seen only by other devices within that network. But unlike the public IP address that...
如果目的IP与自己在一个网段,本机直接发送,否则将报文发送给defaultGateway。事实上,defaultGateway可以是主机自己,如果:这台主机激活路由功能,有本地路由表,支持常见路由协议;有多个不同的网络接口(网卡),连接不同的网段;猜猜,互联网上的路由器,如果有一封管理报文要发送时,他怎么干的?
从Oracle 11g开始,安装RAC至少需要7个IP地址,两块网卡(一块公网网卡,一块私网网卡),其中public、vip和scan都在同一个网段,使用的是公网网卡,private在另一个网段,使用的是私网网卡。主机名不能包含下横线,如:RAC_01是不允许的。通过执行ifconfig -a检查两个节点的网络设备名称是否一致。另外,在配置了/etc/hos...

在Oracle RAC环境下,每个节点都会有多个IP地址,分别为Public/Private/Vip,这三个IP到底有啥区别呢?分别用在那些场合呢?来看看老外的回答。 1. private IP address is used only for internal clustering processing (Cache Fusion) 私有IP用于心跳同步,这个对于用户层面,可以直接忽略,简单理解,这个Ip用来保证两台服...
