一、自動化批量安裝ORACLE軟件的構想
1、1構想從哪裏來？
熟悉PXE+KICKSTART一鍵批量安裝Liunx操作系統的童鞋都知道，該方式可實現快速定制，規範化，自動化的無人值守安裝。基於此方式，安裝oracle軟件也可通過類似方式實現。
1、2為什麽要自動化安裝oracle軟件
? 可實現自動化，批量化，省時省力快速安裝（如一次性安裝10個oracle客戶端）。
? 使安裝軟件更加標準化，規範化（如UID,GID,安裝目錄等保持一致，便與管理）。
? oracle安裝介質同一存放，易於管理和維護。
二、自動化批量安裝ORACLE軟件的架構
2、1自動化批量安裝oracle軟件的大致架構
基本實現思路是：搭建軟件資源庫，提供HTTP或FTP服務，並提供YUM服務，然後下發安裝oracle軟件所需要的文件，所需安裝軟件的服務器作為客戶端，接收文件，通過shell腳本實現自動化配置安裝的成所需的數據庫環境。

2、2搭建軟件資源庫服務
這裏通過tomcat搭建一個WEB站點，提供HTTP的服務（過程略，通過apache、vsftp等也是可以實現相同功能的），搭建後的效果如下：

2、3制作響應RESPONSE文件模板

三、實現自動化靜默安裝的SHELL腳本（LINUX平臺）

（腳本還存在還得需要調整的地方，希望有興趣的朋友一起繼續完成，這裏先將我個思路分享出來，有興趣的童鞋，歡迎一起研究，或者有好的方法一起改寫）

3、7 配置腳本執行用法

因腳本化，需要考慮的問題還有很多，所以還有很多細節需要調整，腳本目前只給出的框架，有興趣的童鞋，歡迎一起研究，或者有好的方法一起改寫。

四、克隆安裝ORACLE軟件實現補丁一同安裝
4、1 克隆安裝ORACLE的可行性
通過上面的安裝過程，細心的你一定發現，只是安裝了oracle軟件，而相應要打的PSU並沒有打上，有沒辦法安裝和打補丁一起呢？有，那就是克隆。為了保證克隆安裝後，不出現問題，首先要保證tar包的準確性，這種安裝方式用於生產環境是有一定風險的，但對於開發環境和測試環境，我覺得是可行的。
4、2 克隆安裝ORACLE的大概步驟
?系統環境準備，ip、/etc/hosts等這些配置，之後再執行其它環境配置的腳本
?克隆安裝oracle軟件shell主體（install_oracle_main.sh）
?系統配置及tar安裝介質下載（install_configure.sh）
?RPM包安裝及配置（install_rpm.sh）
?軟件安裝用戶建立及用戶環境配置（create_user.sh）
?RAC安裝的SSH等效配置（ssh_setup.sh）
?進行克隆安裝，這裏考慮的地方還是蠻多的，難點也在於ASM的克隆，若是RAC，OCR的註冊這些。用戶的uid、gid是否一致，需要安裝的oracle home目錄是否一致等。
五、延伸擴展（定制ORACLE安裝的ISO鏡像文件）
熟悉操作系統安裝和ORACLE的童鞋都知道，我們在Linux環境安裝ORACLE的時候都知道，很多服務都是用 不到的，比如bluetooth藍牙、cups打印服務這些都是不需要的，像這類服務如果在安裝操作系統的時候多安裝了，並開啟了肯定是會占用一定的資源的。這裏有個構想，使用UltraISO直接制作安裝ORACLE的ISO鏡像，去除不必要服務RPM包，將oracle安裝包”database”加入到ISO鏡像中，直接在安裝操作系統的同時，一同安裝數據庫。有興趣的童鞋可以研究一下。
