Real World ADF Design & Architecture Principles

15th Feb 2013 v1.0


Learning Objectives

•  At the end of this module you should be able to:

– Understand what application deployment models WLS supports – What prerequisites you must put in place before deploying an

application to WLS – What options you have for deploying ADF applications to WLS

Prerequisites & Presentation Scope Before considering deployment you need to understand "building" ADF applications. Ensure you've viewed the sister PPT first.

Primary focus of this PPT is the tools for deploying ADF applications, not the "methodology" and associated processes and literature on build & deployment automation, that's up to you to define.


Program Agenda

•  WLS Supported Deployment Units •  ojdeploy vs Deployment •  Deployment Prerequisites •  Deployment Options

–  JDeveloper IDE –  WLS Administration Console –  Oracle Enterprise Manager "FMW Control" Console –  weblogic.Deployer –  WLST


WLS Supported Deployment Units

•  WLS supports several different Java EE deployment units •  Relevant to ADF applications:

–  Enterprise Applications (EARs) Suitable for ADF Applications –  Web Applications (WARs) –  Shared Java EE Libraries (JARs) Suitable for ADF Libraries

•  An EAR can comprise your Web Application (WAR) and ADF Libraries •  Or the ADF Libraries can be separately deployed as Shared Libraries

Exercise

Hmm, what are the advantages and disadvantages of using

WLS shared libraries?

Exercise


If we're talking about deployment, surely this is a discussion about ojdeploy?! Can't ojdeploy deploy our software to our servers?


ojdeploy for Deployment?

•  The use of the terms "build" and "deployment" are subjective •  In this training

–  To "Build" the software •  Is to compile the source and create the JAR/WAR/EAR •  This is what ojdeploy does •  The original ojdeploy authors subjectively called this the act of "deploying"

–  To "Deploy" the software •  Is to install the JAR/WAR/EAR in the Java EE server •  For the definition of this training, this isn't what ojdeploy does

•  This presentation focuses on how to deploy to the server


Program Agenda




Exercise


What are the prerequisites for deploying an ADF

application to a server?


ADF Deployment Prerequisites •  JAR/WAR/EAR is available to deploy

–  Via JDeveloper you've previously created a deployment profile –  Generated JAR/WAR/EAR via the deployment profile and build tools

•  ADF runtime libraries already installed & targeted to WLS managed servers –  These must match the version of JDev/ADF your application was built on –  And version of WLS the ADF runtimes are supported on –  Ensure to read Oracle Support notes on installing ADF runtimes –  Unofficial summary of ADF Runtime install instructions (courtesy Timo Hahn)

•  http://tompeez.wordpress.com/2011/09/14/jdeveloper-versions-vs-weblogic-server-versions/

•  Other software deployments may need to be completed beforehand –  e.g. database changes, system patches etc


Program Agenda




Exercise


One of my "previous" developers botched the deployment of an application to

production, it cost us $1000s to rectify.

He now works in HR.

What choices do we have for deploying ADF applications? Which options can be

automated?


Options in Deploying ADF Applications

•  Manually deploy via –  JDeveloper IDE –  WLS console –  Oracle Enterprise Manager "FMW Control" console

•  Automated deploy via –  weblogic.Deployer –  WLST –  Maven WLS Deployment Plug In

The key to a stress-free, efficient & error free deployment is to remove humans from the process as much as possible,

and automate all the way.

Maven WLS Deployment Plug In

•  Previous automated options via Ant can be integrated into your CI engine •  WLS also provides Maven a Deployment Plug In •  Allows via pom.xml a WLS deployment to be a Maven goal

•  (More info pending dependent on research into the plug-in’s capabilities)


Conclusion

•  Automate, automate, automate
