系统环境：
操作系统：RedHat EL5
Cluster： Oracle CRS 10.2.0.1.0
Oracle： Oracle 10.2.0.1.0
如图所示：RAC 系统架构
案例：
本案例是从 Oracle 10.2.0.1.0 升级到10.2.0.4.0，作为Oracle的补丁升级（CPU Update）。
升级步骤：
1、CRS 升级（对于CRS 升级可以采用滚动升级，本案例采用了滚动升级）
2、Oracle 软件升级
3、DataBase 升级（可以采用dbua 或 sqlplus 命令升级）
一、升级CRS (ROLLING UPDATE)
升级前的准备：
[oracle@node1 ~]$ sqlplus '/as sysdba'

1)先在node1上进行升级
在node1上升级CRS:
[root@node1 ~]# uname -a
Linux node1 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:43 EDT 2010 i686 i686 i386 GNU/Linux
[root@node1 ~]# crsctl query crs softwareversion
CRS software version on node [node1] is [10.2.0.1.0]
[root@node1 ~]# crsctl check crs
CSS appears healthy
CRS appears healthy
EVM appears healthy
[root@node1 ~]# crs_stat -t

在node1上关闭Instance：
[oracle@node1 ~]$ srvctl stop instance -d prod -i prod1
在node1上关闭ASM：
[oracle@node1 ~]$ srvctl stop asm -n node1
在node1上关闭nodeapps：
[oracle@node1 ~]$ srvctl stop nodeapps -n node1
[oracle@node1 ~]$ crs_stat -t

2）下载和解压补丁软件（对于RAC升级CRS和Oracle软件都是用相同的补丁软件）
[oracle@node1 ~]$ unzip p6810189_10204_Linux-x86.zip
升级CRS 10.2.0.1.0 到 10.2.0.4.0，如下图所示：
以Oracle用户的身份执行：runInstaller
开始升级
注意升级目录：应该是CRS的安装目录
升级安装
补丁软件升级过程
按照提示执行script
[root@node1 ~]# crsctl stop crs

[oracle@node1 ~]$ crsctl query crs softwareversion
CRS software version on node [node1] is [10.2.0.4.0]
[oracle@node1 ~]$
node1 的CRS升级成功！
3）升级node2的CRS(步骤与node1相同）
[root@node1 ~]# srvctl stop instance -d prod -i prod2
[root@node1 ~]# srvctl stop asm -n node2
[root@node1 ~]# srvctl stop nodeapps -n node2
以下为升级过程过程中与node1不同的画面：
选择“select all”
升级软件安装完成后，按照提示执行script
[root@node2 ~]# crsctl stop crs
[root@node2 ~]# /u01/crs_1/install/root102.sh
[root@node2 ~]# crsctl query crs softwareversion
CRS software version on node [node2] is [10.2.0.4.0]
node2的CRS升级完成！
[root@node1 ~]# crs_stat -t
