在數據庫實例的alert日志中出現“WARNING: No cluster interconnect has been specified”
來源於：
No Interconnect Defined Signalled In Alert.Log (文檔 ID 359268.1)
適用於：
Oracle Server - Enterprise Edition - Version: 10.2.0.1 and later [Release: 10.2 and later ]
Information in this document applies to any platform.
症狀：
在啟動數據庫實例時，alert日志中報錯：
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帶有.(即：點)的網卡名稱
運行'oifcfg iflist'命令，得到如下的結果：
Public_Vlan 1_165.17.2.xxx 165.17.2.0 Private_VLAN254_165.17.254.xxx 165.17.254.0
請注意，如上的輸出顯示，網卡的名稱為：
Public_vlan1_165.17.2 和 Private_vlan254_165.17.254
也就是說網卡的名稱帶有點
解決方案：
1.對網卡的名稱進行重新命名，去掉其中的任何的點
2.運行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
停止並出錢Clusterware 和數據庫。
檢查數據庫實例中不在有該報錯
