1.解压升级所需补丁包：p8202632_10205_LINUX.zip
[oracle@rac1 soft]$ unzip p8202632_10205_LINUX.zip
2.開始升级集群软件
[oracle@rac1 Disk1]$ ./runInstaller
然后依照要求跑脚本：
rac1节点

[root@rac1 bin]# ./crsctl stop crs

到眼下，Clusterware软件升级完成

如今開始升级数据库软件：
升级数据库软件前我们要关闭CRS的各种服务
[oracle@rac1 Disk1]$ srvctl stop db -d RACDB -o immediate
[oracle@rac1 Disk1]$ srvctl stop asm -n rac1 -o immediate
[oracle@rac1 Disk1]$ srvctl stop asm -n rac2 -o immediate
[oracle@rac1 Disk1]$ srvctl stop listener -n rac1
[oracle@rac1 Disk1]$ srvctl stop listener -n rac2
[oracle@rac1 Disk1]$ crs_stop -all
[root@rac1 ~]# cd /u01/app/oracle/product/10.2.0/db_1/bin/
[root@rac1 bin]# ./crsctl stop crs
rac2节点：
[root@rac2 ~]# cd /u01/app/oracle/product/10.2.0/db_1/bin/
[root@rac2 bin]# ./crsctl stop crs
执行补丁包（和升级集群软件使用的同一个补丁包）
[oracle@rac1 Disk1]$ ./runInstaller
这次我们选择ORACLE_HOME文件夹
rac1节点：
[root@rac1 ~]# /u01/app/oracle/product/10.2.0/db_2/root.sh
Running Oracle 10g root.sh script...
The following environment variables are set as:
ORACLE_OWNER= oracle
ORACLE_HOME= /u01/app/oracle/product/10.2.0/db_2
Enter the full pathname of the local bin directory: [/usr/local/bin]:
The file "dbhome" already exists in /usr/local/bin. Overwrite it?
(y/n)
[n]:
The file "oraenv" already exists in /usr/local/bin. Overwrite it?
(y/n)
[n]:
The file "coraenv" already exists in /usr/local/bin. Overwrite it?
(y/n)
[n]:
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.

数据库软件升级完成后開始升级数据库：
版本号升级后，在新的版本号下，字典表中某些对象的属性也须要随之改变。所以，须要继续升级一下数据库，更新数据库字典。
rac1节点：
[root@rac1 ~]# cd /u01/app/oracle/product/10.2.0/db_1/bin/
[root@rac1 bin]# ./crsctl start crs

The CRS stack will be started shortly
