之前写过一篇为rac建dns server的文章,今天在安装11.2.0.3的grid的时候报错 PRVF-5636 : The DNS response time for an unreachable node exceeded “15000” ms on following nodes
同时,在rac主机上尝试nslookup unknown-not-reachable-node会长时间没响应。
解决方法:
需要在dns server的/etc/named.conf修改
1 2 3 4 5 6 |
zone "." IN { type hint; // file "named.ca"; file "/dev/null"; |
在每个rac主机:
1 2 3 4 5 6 7 8 9 |
[root@rac2 ~]# vi /etc/resolv.conf search oracleblog.org nameserver 192.168.190.220 ##nameserver 192.168.190.1 options rotate options timeout:2 options attempts:5 ~ |
