Oracle grid 11gR2 安装报错PRVF-5636

问题现象:

在Oracle grid 11.2.0.3/4安装的时候报PRVF-5646: The DNS response time for an unreachable node exceeded “15000″ ms on following nodes

问题解决办法:

1、修改DNS服务器的/etc/named.conf文件,添加fil "/dev/null";信息即可。

zone "." IN {
 
      type hint;
 
//      file "named.ca";
        file "/dev/null";

2、在RAC节点主机分别添加如下参数:

[root@rac2 ~]# vi  /etc/resolv.conf
 
search prudentwoo.com
nameserver 192.168.7.51
nameserver 192.168.7.52
options rotate
options timeout:2
options attempts:5
