Oracle 11.2.0.3 [INS-41112] Specified network interface doesnt maintain connectivity across cluster

安裝Oracle 11.2.0.3 的RAC，在Grid 安裝時報錯：

[INS-41112]Specified network interface doesnt maintain connectivity across cluster nodes

首先嘗試在節點間ping 各個IP 位址沒有問題。

因為使用安裝程式做的SSH 驗證，是以嘗試測試ssh遠端連接配接是否還需要确認：

[grid@rac2 ~]$ ssh rac2 dae

bash: dae: command not found

[grid@rac2 ~]$ ssh rac2 date

[grid@rac2 ~]$ ssh rac1 date

Thu Dec 20 21:21:05 CST 2012

[grid@rac2 ~]$ ssh rac2-priv date

The authenticity of host 'rac2-priv(192.168.56.200)' can't be established.

RSA key fingerprint is a2:23:fe:22:50:03:e0:db:01:ff:76:f1:21:55:86:6a.

Are you sure you want to continueconnecting (yes/no)? yes

Warning: Permanently added'rac2-priv,192.168.56.200' (RSA) to the list of known hosts.

[grid@rac2 ~]$ ssh rac1-priv date

The authenticity of host 'rac1-priv(192.168.56.100)' can't be established.

[grid@rac2 ~]$

發現使用rac-priv時需要确認，在2個節點間互相确認後，該步驟通過驗證。小東西，随筆記之。
