本节中将演示升级rac的步骤，将rac的版本从10.2.0.1升级到10.2.0.5，对于生产环境而言，升级前需要先对数据库和ocr，表决盘等进行备份!

一：上传升级包到节点1并解压,可以在support.oracle.com上下载到该软件包
[oracle@rac1 patch]$ unzip p8202632_10205_Linux-x86-64.zip
[oracle@rac1 patch]$ ls
Disk1  p8202632_10205_Linux-x86-64.zip  README.htm

二：关闭所有的rac节点，不推荐使用crs_stop -all命令关闭，容易出现unknown现象

[oracle@rac1 ~]$ crs_stat -t
Name           Type           Target    State     Host       
------------------------------------------------------------
ora....SM1.asm application    ONLINE    ONLINE    rac1

ora....b2.inst application    ONLINE    ONLINE    rac2

[oracle@rac1 ~]$ crs_stat -t

ora.racdb.db   application    OFFLINE   OFFLINE

ora....b2.inst application    OFFLINE   OFFLINE

三：升级CRS
[oracle@rac1 patch]$ cd Disk1/
[oracle@rac1 Disk1]$ ./runInstaller

按照提示，运行下面两个脚本

在rac2节点上运行这两个脚本，完成后点exit按钮完成CRS的升级

四：升级数据库软件,前面升级完crs后，rac会自动启动，因而同样需要先关闭rac服务

[oracle@rac1 ~]$ crs_stat -t -v
Name           Type           R/RA   F/FT   Target    State     Host

ora....b2.inst application    0/5    0/0    OFFLINE   OFFLINE  

[oracle@rac1 Disk1]$ ./runInstaller

[root@rac1 ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh

Enter the full pathname of the local bin directory: [/usr/local/bin]:

Entries will be added to the /etc/oratab file as needed by
Database Configuration Assistant when a database is created
Finished running generic part of root.sh script.
Now product-specific root actions will be performed.
同样需要在rac2节点上运行这个脚本！

五：升级数据库，需要先将数据库启动到nomount的状态，修改cluster_database初始化参数，然后重新启动实例，升级数据字典(持续时间较长)，从新编译无效的对象等

[oracle@rac1 ~]$ crs_stat -t -v
