在Oracle中,RAC中的Public IP、Private IP、Virtual IP、SCAN IP、GNS VIP及HAIP的作用分别是什么? ♣答案部分 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...
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...
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...

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...
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...
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 ...
Private IP addressesYou can allocate both types of IP addresses in one of two ways:Dynamic StaticLet's take a closer look at how the IP address types work together.Public IP addressesUse a public IP address for public-facing services. A public address can be either static or dyna...
But I will go with a Private IP address if really not required. Because those two IP addresses are not going publicly anymore. Regards, Deepak Kumar Regards,Deepak Kumar, Don't forget to vote and accept the solution if this comment will help you! 0 Helpful Reply paul driver VIP ...
RAC中的各种IP-PUBLIC-VIP-Private-SCAN IP 1、PUBLIC和VIP Oracle RAC中每个节点都有一个虚拟IP,简称VIP, 与公网PUBLIC IP在同一个网段。vip 附属在public网口接口。 VIP和PUBLIC IP最主要的不同之处在于:VIP是浮动的,而PUBLIC IP是固定的。在所有节点都正常运行时,每个节点的VIP会被分配到public NIC上;在li...
