适用于：
Oracle Server – Enterprise Edition – Version: 10.2.0.1 and later [Release: 10.2 and later ]
Information in this document applies to any platform.
症状：
在启动数据库实例时，alert日志中报错：
WARNING: No cluster interconnect has been specified. Depending onthe communication driver configured Oracle cluster trafficmay be directed to the public interface of this machine.Oracle recommends that RAC clustered databases be configuredwith a private interconnect for enhanced security andperformance.
原因：
Clusterware 不能copy带有.(即：点)的网卡名称
运行'oifcfg iflist'命令，得到如下的结果：
Public_Vlan 1_165.17.2.xxx 165.17.2.0Private_VLAN254_165.17.254.xxx 165.17.254.0
请注意，如上的输出显示，网卡的名称为：
Public_vlan1_165.17.2和Private_vlan254_165.17.254
也就是说网卡的名称带有点
解决方案：
1.对网卡的名称进行重新命名，去掉其中的任何的点
2.运行oifcfg命令以更新ocr
a) oifcfg delifc) oifcfg getifd) oifcfg setif -global "naoracle账号me 1 without dots"/ip address:publice) oifcfg setif -global "name 2 without dots"/ipaddress:cluster_interconect
停止并出钱Clusterware 和数据库。
检查数据库实例中不在有该报错
