Oracle 11g RAC 添加新节点及故障解决案例
系统环境：
操作系统：RedHat EL55
集群： Oracle 11g GI
Oracle： Oracle 11gR2
一、配置新的节点
1.首先按照其他节点进行 系统基本参数配置
2.添加hosts到所有节点 并完成用户等效性配置 (grid,oracle)2个用户
二、添加GRID节点
以grid用户登录
静默方式 完成grid节点添加
# su - grid
[grid@node1 ]$ cd $ORACLE_HOME/oui/bin
[grid@node1 bin]$ ./addNode.sh "CLUSTER_NEW_NODES={node3}" "CLUSTER_NEW_VIRTUAL_HOSTNAMES={node3-vip}"
