ORACLE RAC 11G 更改 /etc/hosts文件

来自官方文档：
（1）Can I change the public hostname in my Oracle Database 10g Cluster using Oracle Clusterware?   Hostname changes are not supported in Oracle Clusterware (CRS), unless you want to perform a deletenode followed by a new addnode operation.  The hostname is used to store among other things the flag files and Oracle Clusterware stack will not start if hostname is changed. （2）Does the hostname have to match the public name or can it be anything else?   When there is no vendor clusterware, only Oracle Clusterware, then the public node name must match the host name. When vendor clusterware is present, it determines the public node names, and the installer doesn't present an opportunity to change them. So, when you have a choice, always choose the hostname.

由于之前的安装失误，将/etc/hosts文件配置成如下格式

#管理网段 30.11.3.178  rappdb1 30.11.3.179  rappdb2 #public IP 30.2.21.161  rappdb1-pub 30.2.21.163  rappdb2-pub  30.2.21.162  rappdb1-vip 30.2.21.163  rappdb2-vip  172.2.21.101  rappdb1-priv 172.2.21.102  rappdb2-priv

当安装完成后，监听中发现监听的是 管理IP（30.11.3.178）和VIP（30.2.21.162），正常应该是监听PublicIP和VIP。一般不建议直接修改hosts文件。

修复操作如下：
