The Characteristics of a Development
Environment
• A rich set of developer productivity tools that
– Make it easy to get started with new
technologies
– Assist rapid development for expert users
– Provide a responsive environment to test
against
– Provide a test environment that has fidelity
with the target production environment



What constitutes “Fidelity”?
• The application programming model available in the Dev Env
faithfully reflects that of the production system
– Application code and configuration
– Application bindings (types, if not values)
• Code that cannot run properly in a production environment should
be flagged as such in the test environment
• Ability to test with the same semantic behavior as production
system when container-managed QoS is configured.
– Easy to test basic function to get it up and running
– Easy to engage QoS within Dev Env with same behavior as
production runtime



How is Fidelity Achieved?
Authoring and Debug and Run
• By testing on a server

The Development Profile

• By default, WAS servers defined to RAD are
configured with a Development profile as the
best compromise between fidelity and a
responsive test environment

Development Profile

• Optimized for devt activities
such as publishing apps
• Smaller thread pools
• Less resources
• Disable activity log
• -Xquickstart JVM option
to defer JITing
• Faster server startup
• No default apps installed


Frequency of Development Tasks
• Common development tasks include:
fastest
• Modify file within an application
• Debug a problem in an application
Hourly • Restart/redeploy application
• Restart server
Daily • Share code with team
• Change app structure (add/remove a module/bundle)
faster
• Make config change
Weekly
• Share config change with team
• Reproduce problem from another environment
Monthly • Upgrade to new service release
• Create application
• Install server fast

Frequency Time to complete

• All tasks should be as painless as possible, with special emphasis on the more
frequent ones. If the time taken to accomplish these tasks is an impediment to
the development, the cost of the fidelity of the test server runtime is challenged.



Developer Feedback

• Developers are looking for more (or less) from the test
server runtime in the tools.
– Greater test simplicity
• Config model (hard to edit, backup, share)
• Admin console is for operational mgmt rather than development
• Problem determination (including within customer apps)
– Responsiveness
• Incremental publishing, app install, server startup time
– Footprint
• WAS server types defined to RAD have a WAS production server
footprint and memory use.
– For all types of application
• Tools available only as part of RAD distributions



What Next for WebSphere Dev/Test Tools and
Runtime?
WAS V8.5 Alpha introduces:
• A new dynamic profile of WAS which is focused FIRST on
the development experience
– Small footprint test server runtime
– Simplified, shareable config
– Fastest possible server start-up
• Fidelity with full-profile WAS
– Same containers, QoS as full-profile WAS
– But radically refactored to focus on the development experience
– Extreme dynamicity to start what the app requires and no more
• Initially focused on dev/test of web, mobile and OSGi apps.

WAS V8.5 Alpha: Introducing WAS
“Liberty” Profile
• Not a single static profile: rather a dynamic, flexible profile of the
runtime to load only what the application needs
– Memory footprint (web feature): < 50 MB
– Profile is dynamic – switch parts of the server on and off without
restart.
• Extremely lightweight
– Incredibly fast (re)start times: <5 seconds
• Simplified configuration for quick time to productivity; one single
config file or modular config (as desired).
– Easy to share / diff / manage in version control
– Easy to componentize configuration across larger development
teams
• Tools available as Eclipse features as well as in RAD…

– Deploy applications unchanged to full profile WAS for production



Create a Lightweight WAS Server in WDT

Create a lightweight WAS
server configuration in
seconds.



Simplified Sever Configuration

• Simplest case:
1 XML file for all
server config
• Editable within
the workspace
• Exportable,
shareable,
versionable
resources.xml
No need for Admin Console, wsadmin, server.xml etc.
or extended EARs ws-security.xml


Simplified Configuration
<server> features control which capabilities
(bundles) are installed in the server
<featureManager>
<feature>jsp-2.2</feature>
'singleton' configurations specify
<feature>derby-10.5</feature>
properties for a runtime service like
</featureManager> logging

<logging trace.specification=”webcontainer=all=enabled:*=info=enabled” />
'instance'
configurations specify
<application type="war" id="tradelite" name="tradelite"
multiple resources like
location="tradelite.war" /> applications and
<datasource id=“ds" jndiName="jdbc/TradeDataSource" datasource definitions
databaseName="${shared.resource.dir}/data/tradedb"/>
</server>
Any of this configuration could be put
into a separate xml file and 'included' in
this 'master' configuration file


Flexible Configuration
• Shareable config snippets

<server>
...
<include url="http://hurgsa.ibm.com/~irobins/
was4d/config/blog.sample.xml" />
<include file="${shared.config.dir}/datasource.xml" />
<server>
server.xml

• Config can be componentized at any level of granularity, from 1
file to many.
– Can use WDT to associate config snippets with a server config.
• Visualization through WDT tools as a single logical view.
• Team development: keep the application and configuration
components together.
