首先升级clusterware补丁，在图形界面中运行./runInstaller进行安装，注意选择正确的路径，比如clusterware软件的路径在“/home/db/oracle/crs"下，那么就必须指定这个路径，否则得不偿失。
具体过程略过，在补丁安装完毕之后，系统提示需要分别在两个节点下进行如下步骤：
首先在副节点上按照提示的步骤进行执行（主次顺序无所谓）：
[storm02@/home/db/oracle/crs/bin]#./crsctl stop crs
Stopping resources. This could take several minutes.
Successfully stopped CRS resources.
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
这时可以看到副节点的vip地址被主节点所接管：
接着执行root102.sh脚本：
[storm02@/home/db/oracle/crs/bin]#cd ..
[storm02@/home/db/oracle/crs]#cd install
[storm02@/home/db/oracle/crs/install]#ls
cluster.ini install.incl preupdate.sh rootdelete.sh templocal
cmdllroot.sh make.log root102.sh rootdeletenode.sh
envVars.properties paramfile.crs rootaddnode.sbs rootinstall

[storm02@/home/db/oracle/crs/install]#sh root102.sh

黑体字部分显示副节点上clusterware的补丁已经成功安装。
补丁打完之后，重新启动副节点上crs进程，这个时候会把数据库一起给启动起来，所以切记一定要关闭数据库以及监听进程，防止在打database补丁的时候出错。
副节点上补丁打完之后，再按照相同的步骤给主节点打补丁，最后运行root102.sh脚本。
在这之后，分别在两个节点上进行clusterware版本的验证：
[storm01@/home/db/oracle/crs/bin]#./crsctl query crs softwareversion
CRS software version on node [storm01] is [10.2.0.4.0]
[storm02@/home/db/oracle/crs/bin]#./crsctl query crs softwareversion
CRS software version on node [storm02] is [10.2.0.4.0]
确认无错之后，紧接着进行数据库补丁的升级，其过程不赘述，但一定要保证监听和数据库是关闭状态。
