确认网络及心跳都设置正确
[root@rac3 ~]# ping rac1
[root@rac3 ~]# ping rac2
[root@rac3 ~]# ping rac1-priv
[root@rac3 ~]# ping rac2-priv
[root@rac3 ~]# rlogin rac1
[root@rac3 ~]# rlogin rac2
[root@rac3 ~]# rlogin rac1-priv
[root@rac3 ~]# rlogin rac1-priv
l Oracle软件相关配置
在操作系统装好以后，需要启动rsh、rlogin、rexec服务，打上安装ORACLE需要的补丁，修改内核参数，并正确定设置环境变量，目录要求和其它节点一样。
export LD_ASSUME_KERNEL=2.4.1
export ORACLE_BASE=/u01/oracle
export ORACLE_HOME=/u01/oracle/product/9.2
export PATH=$ORACLE_HOME/bin:$ORACLE_HOME/Apache/Apache/bin:$PATH
export ORACLE_OWNER=oracle
export ORACLE_SID=rac3
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/local/lib:$LD_LIBRARY_PATH
export DISPLAY=192.168.88.10:0.0;
export DBCA_RAW_CONFIG=/home/oracle/filename
复制rac2点的软件目录至rac3
[oracle@rac3 ~]$ cd /u01/oracle/product/9.2/
[oracle@rac3 9.2]$ rcp -rp rac1:/u01/oracle/product/9.2/* .
[oracle@rac3 9.2]$ cd /u01/oracle/product/9.2/oracm/admin/
l 识别共享磁盘
在rac3上识别共享磁盘并挂载裸设备。
