Oracle 11gR2 RAC添加新节点错误之--IP子网掩码

系统环境：

操作系统：RedHat EL5

Cluster： Oracle GI(Grid Infrastructure)

Oracle： Oracle 11.2.0.1.0

如图所示：RAC 系统架构

对于Oracle 11G构建RAC首先需要构建GI(Grid Infrastructure)的架构

案例分析：

在Oracle 11gR2 RAC在添加新节点时，添加grid，在node3上执行root.sh时，出现以下错误：

[root@lxh3 ~]# /u01/11.2.0/grid/root.shRunning Oracle 11g root.sh script...

The following environment variables are set as:

ORACLE_OWNER= grid

ORACLE_HOME= /u01/11.2.0/grid

Enter the full pathname of the local bin directory: [/usr/local/bin]:

Copying dbhome to /usr/local/bin ...

Copying oraenv to /usr/local/bin ...

Copying coraenv to /usr/local/bin ...

Creating /etc/oratab file...

Entries will be added to the /etc/oratab file as needed by

Database Configuration Assistant when a database is created

Finished running generic part of root.sh script.

Now product-specific root actions will be performed.
