RAC配置2个私网网卡使用HAIP服务

      如果是在oracle 10gRAC, 私网网卡冗余保护只能使用操作系统网卡绑定方式，但是到了oracle 11g,如果担心一个私网网卡故障导致rac节点驱逐，可以使用2个私网网卡，Oracle将自动使用HAIP服务冗余私网网卡。

     HAIP之后，无需使用网卡绑定就可以实现私网网卡的冗余。

     如下测试环境rac 2节点,linux redhat6.9

1.配置

#/etc/hosts
10.0.0.11 wsgwa1
10.0.0.12 wsgwa2
192.168.53.11 wsgwa1-priv1
192.168.54.11 wsgwa1-priv2
192.168.53.12 wsgwa2-priv1
192.168.54.12 wsgwa2-priv2
10.0.0.13 wsgwa1-vip
10.0.0.14 wsgwa2-vip
10.0.0.15 wsgwa-scan

# cd /etc/sysconfig/network-scripts/
[root@wsgwa2 network-scripts]# cat ifcfg-eth1 
DEVICE=eth1
IPADDR=192.168.53.12
BOOTPROTO=static
ONBOOT=yes
[root@wsgwa2 network-scripts]# cat ifcfg-eth2
DEVICE=eth2
IPADDR=192.168.54.12
BOOTPROTO=static
ONBOOT=yes
HWADDR=00:0C:29:3F:A5:98

 

 

2.测试，down一个私网网卡，如果rac只有一块私网网卡， 假设rac 2节点，将导致节点2被驱逐。
