Oracle Appliactions 11i concepts(一) - Application 基本架構(1)

近來專案中的大事已經完全做完,系統也執行正常,所以,富裕時間比較多,乘機把Oracle Applications 11i 的官方文件,再系統的閱讀一遍,發現每閱讀一遍,都有不同的理解!

本章主要介紹Oracle Applications 11i 基本概念中 的Application 基本架構

1. 特別強調

Oracle 強烈建議千萬不要用SQL*Plus ,Oracle Data Brower,Database Triggers 或者其他工具去修改Oracle Applications data .Oracle 會提供專門的工具去做修改

2. Oracle Applications 一般由"Desktop tier/Application Tier /Database Tier" 3 層構成

3. Desktop tier

- 客戶端透過帶有JAVA-ENABLED Brower with JInitiator 透過JAR file +WAN 去訪問Application tier

4.Application Tier

- 主要有Web Server /Form server/report Server/Discoverer server /Concurrent Processing Server/Admin server 6 部分構成.

5. Load Balancing :

以下SERVER 可以做到Load Balancing

- Web Server

- Forms server

- Report server

- Discoverer Server

- Concurrent Processing Server

6.Web Server

- Web listener

- Java Servelet Engine

- JavaServer pages(JSP)

7.HTML-Based Applications architecture

Brower(Client)->Listener->Servlet Engine(JSP) ->Metadata Dictionary ->Data ->Servlet Engine(JSP)-> Listener ->Brower

8. Oracle Applications Framework Architecture

Client Web Server data server

Brower Weblistener

Servlet Engine metadata

Java Controller Metadata respository

(Programmatic UI Definition)(UI Definition)

UIX

(HTML UI Generator) Applications

AOL/J BC4J schema

(Security and Content) (Application Buessnis Logic)

9. Form server architecture

Brower running Jinitiator ,a java plug-in - > Web Listener ->Forms server(User Interface Logic) ->data server -> Forms server(User Interface Logic) -> Forms client running in the same brower-> Brower running Jinitiator,a java plug-in
