RAC添加新节点步骤整理

1.老节点oracle及grid用户下检查：
cluvfy stage -pre nodeadd -n rac3 -verbose
2.grid下新节点执行添加节点
cd /u01/app/11.2.0/grid/oui/bin/
./addNode.sh -silent "CLUSTER_NEW_NODES={rac3}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={rac3-vip}"
3.root用户下新节点执行脚本
[root@rac3 etc]# /u01/app/11.2.0/grid/root.sh
--Clusterware添加完成
4.Oracle用户在老节点执行命令，为新节点添加RAC DB软件
/u02/app/oracle/product/11.2.0/dbhome_1/oui/bin
./addNode.sh -silent "CLUSTER_NEW_NODES={rac3}"
5.在新节点root用户执行root.sh脚本
$ORACLE_HOME/root.sh
6.验证Clusterware和RAC DB软件的安装,在新旧节点均可，grid以及oracle用户
cluvfy stage -post nodeadd -n rac3 -verbose  （有错，没有管，直接进行下一步）
7.添加新节点实例，现有集群节点oracle

./dbca -silent -addInstance -nodeList "rac3" -gdbName "ron" -instanceName "ron3" -sysDBAUserName "sys" -sysDBAPassword oracle

[oracle@rac3 ~]$ sqlplus / as sysdba
