前提：安装oracle软件后，完成了dbca建库
目标：完成oracle软件由10.2.0.1.0升级为10.2.0.5.0
[oracle@hyl ~]$ sqlplus ‘/as sysdba‘
SQL*Plus: Release 10.2.0.1.0 - Production on Wed Sep 17 18:27:42 2014

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production

SQL> select instance_name,status from v$instance;
INSTANCE_NAME STATUS
---------------- --------------------
hyldb OPEN
SQL> select comp_name,version,status from dba_registry;
找到oracle10g的升级安装包，如下所示：
解压压缩包
[root@hyl soft]# unzip p8202632_10205_Linux-x86-64.zip
[oracle@hyl ~]$ sqlplus ‘/as sysdba‘

生产环境时此处需要做一次备份，以免升级失败时造成数据丢失，此文省略。
远程调用图形化界面，如下图例：
这里跳过需求包检查即可，点击yes继续，如下图：
[root@hyl ~]# /u01/app/oracle/product/10.2.0/db_1/root.sh
--按提示执行脚本
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_1
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]: y
Copying dbhome to /usr/local/bin ...
The file "oraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: y
Copying oraenv to /usr/local/bin ...
The file "coraenv" already exists in /usr/local/bin. Overwrite it? (y/n)
[n]: y
Copying coraenv to /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.
执行脚本后，点击界面ok，进入到结束界面，如下：
[oracle@hyl ~]$ sqlplus ‘/as sysdba‘

升级数据字典

至此，数据库完成由10.2.0.1.0升级到10.2.0.5.0版本。
[oracle@hyl ~]$ sqlplus ‘/as sysdba‘
--登陆数据库

对比dbca建库前后进行cpu升级的过程，会发现明显的区别：
1、未进行dbca建库，只需进行软件升级，升级后建库即可；
2、dbca建库后（即存在数据库的情况下），升级软件后，需要升级数据字典，修改兼容性。
