Implement middleware virtualization with IBM Workload Deployer Virtual Application Model (i)

Through the IWD or Pure expert system, the Java-EE platform that the user obtains has the advantages of the expansion characteristic of the computing unit, the loose coupling between application and the operating system, and the design of disaster tolerance. And to achieve this goal of the http://www.aliyun.com/zixun/aggregation/17799.html "> development process is very simple! This article creates a virtual application mode type by using the IWD virtual Application Mode plug-in development tool and the middleware installation media in Eclipse. The installation media used in this article are WebSphere applcation server V8.5 and IBM HTTP server V8.5.

Before starting the text, give the reader an introduction to the objectives of this article, the environment in which it depends, and the audience.

Overall objective

Users in IWD Virtual creator pattern Builder can use the artifacts generated in this article to deploy a Java EE system.

Users only need to fill in the Global Administrator account information, DB instance name, DB JNDI name and upload SQL file, you can deploy.

If you want to try this mode type first, read the last part of this article directly-how to use the Simplend mode type

DB2 represents virtual machines and DB2 instances running DB2.

DMGR represents the virtual machine running the WebSphere receptacle deployment Manager and its instance.

IHS represents virtual machines and middleware running IBM HTTP Server.

Customnode represents the virtual machine running the WebSphere creator Server and the nodes it is managed by DMGR.

In a deployed system, deployment Manager creates resources:
