oracle 12c rac vip和监听故障
环境:aix 7.1 ,oracle 12.1.0.2 rac -3节点。
硬件故障后,硬件工程师更换了内联网卡,不知为何资源VIP也有问题,只好先添加了VIP
srvctl add vip -node rac-wy1 -address rac-wy1-vip.nsn.com/255.255.255.0/en8
修改了下nodeapps
srvctl modify nodeapps -node rac-wy1 -address 10.48.186.99/255.255.255.0/en8
启动listener
srvctl start listener -node rac-wy1
报告故障。

查了不少资料,没有什么特别收获。
看了下grid下listener.ora中配置串出现问题,居然和gv$configured_interconnects中的不一致,也不知道那个狗蛋修改的!
不管了,先按照gv$的来修改吧,然后重启,结果ok!

返回过来看,使用ifconfig -a查看:

从这个看,public,vip,scan在一个网卡上;而私有(内联)的,居然和LISTENER在一个卡上(被更换的)。
按照推测,应该是更换网卡之后,修改了这个ip(不确定是系统自己分配的,还是工程师修改的),但是没有修改grid的listener.ora文件导致的。
看来以后得加强沟通了!
