在数据库实例的alert日志中出现“WARNING: No cluster interconnect has been specified”

来源于：
No Interconnect Defined Signalled In Alert.Log (文档 ID 359268.1)

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 on
the communication driver configured Oracle cluster traffic
may be directed to the public interface of this machine.
Oracle recommends that RAC clustered databases be configured
with a private interconnect for enhanced security and
performance.

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 165.17.2.0
Private_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 delif
c) oifcfg getif
d) oifcfg setif -global "name 1 without dots"/ip address:public
e) 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
