本文详细介绍了Oracle10.2.05版本的升级补丁安装过程，包括解压安装包、执行安装脚本、设置环境变量及创建数据库等步骤，并提及了安装过程中遇到的企业管理器安装失败的问题。

《ORACLE 10.2.05版本的升级补丁安装》
首先我们解压
```
$ unzip p8202632_10205_LINUX.zip 
```
解压后我们会发现多出了个文件夹，他是：Disk1,进入Disk1。然后执行安装：
```
$ ./runInstaller
```

执行脚本

# /u01/app/oracle/10.2.0/db_1/root.sh
Running Oracle 10g root.sh script...
The following environment variables are set as:
    ORACLE_OWNER= oracle
    ORACLE_HOME=  /u01/app/oracle/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]: 
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.

执行完脚本后进行创建数据库。
```
$ dbca
```
这里之前还报了一个错误，说的是企业管理器安装失败。企业管理器是我们DBA日常生活必不可少的工具，所以我们必须要给它安装起来。
