install oracle 10g rac on RHEL 4
RHEL4就是方便，一键全选包

使用ocfs2console添加节点的时候出现问题：

o2cb_ctl: Unable to access cluster service while creating node
        Could not add node thrac1

--解决方法
rm -f /etc/ocfs2/cluster.conf

再次运行ocfs2console就好好了

装完clusterware后要求运行root.sh
其中当最后一个节点运行的时候会触发一个错误

运行一下ORA_CRS_HOME/bin/vipca就ok了

顺利安装以及dbca

故意建立空的数据库
通过dbua升级成功

经过多次失败与尝试后终于搞好了

下午玩一下rolling patch on rac
