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...
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用来保证两台服务器同步数据用的私网IP。 2. VIP is used by database applications to enable fail over when one cluster node fails 虚拟IP用于客户端...

Clusterware:TCP/IP RAC:UDP 多网卡绑定:Linux(bonding)、Solaris(链路聚合)、AIX(EtherChannel) Oracle 建议 private network 至少配置 1GB 的网络 1、GB 级以太网卡 2、Infiniband (Oracle Exadata 解决方案),协议栈比 TCP/IP 少,消耗的CPU 资源少,价格昂贵。 私有网络的OS系统参数调整: 因为集群使用 UDP 协议...
When you connect to the internet, your private IP address is replaced with your ISP-assigned public IP address. This protects your private IP and other devices in your network, while also ensuring you can still connect online. Both types of IP addresses are important for your device’s connec...
因为主机不需要计算路由，将路由计算交给defaultGateway了。在一般主机的简陋的IP层看来，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...
In today’s network environments, it is most common for organizations to have one or more public, routable IP addresses from an ISP assigned to the external interfaces of their firewall appliances. Additionally, they use the designated private IP subnets internally....
记录使用以下的代码获取Azure VM中的IP地址 但是,结果却没有能成功。 遇见问题: 通过Bing搜索查找,怀疑是packages中版本冲突引起。参考链接: https:...
Public IP addresses Private IP addresses You can allocate both types of IP addresses in one of two ways: Dynamic Static Let's take a closer look at how the IP address types work together. Public IP addresses Use a public IP address for public-facing services. A public address can ...
As for most aspects, the Private IP address is the same as a public IP address. It is a unique identifier for all the devices behind a router or other devices that servers IP address. With the private IP address, the devices in your home are able to have the same private IP address ...
