我们知道Linx 6 上安装Oracle 11G R2 RAC时要禁用Firewall 和SElinux ,下面是不禁用Firewall的后果.
使用CVU检查安装环境时遇到PRVF-7617 TCP connectivity check failed for subnet
$./runcluvfy.sh stage -pre crsinst -n bjrac01,bjrac02 -fixup -verbose
ERROR:
PRVF-7617 : Node connectivity between "bjrac02 : 192.168.0.201" and "bjrac01 : 192.168.0.150" failed
Result: TCP connectivity check failed for subnet "192.168.0.0"
原因:Linux中未关闭Firewall
停掉防火墙即可:
service iptables save
service iptables stop
chkconfig iptables off
如果不停防火墙,需要打开那些端口呢。这个目前还不知道。rac起来后,netstat 看有那些端口在使用,打开这些端口。在试试把防火墙起来。
