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...
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...
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...
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...
Explain public and private IP addressingCompleted 100 XP 2 minutes Devices and hosts that connect directly to the Internet require a public IPv4 address. However, hosts and devices that do not connect directly to the Internet do not require a public IPv4 address....

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...
