NOW – Forms Today>HUGE Forms investment>Trained developer pool>Mission critical, complex systems>Best development tool for OLTP
Systems - Desktop>Low maintenance, stable system
for over 10 years>Mostly undocumented systems>VERY fast productive development

“Oracle Forms remains a viable and valuable technology asset for mainstream IT strategies, but has limited scope in next-generation”Gartner: Modernization and Migration Strategies for Oracle Forms Nov. 2011http://www.gartner.com/technology/reprints.do?id=1-198LN9P&ct=120208&st=sb
“Oracle has no plan to discontinue support of Oracle Forms.” “…continue to leverage their existing investments for many years while offering a path to incrementally move to Java EE, at their own pace.”Oracle Application Development Tools SOD , March 2012http://www.oracle.com/technetwork/issue-archive/2010/toolssod-3-129969.pdf

Clean UpDon’t Migrate/Upgrade What’s Not in Use• 10 Year old system – Are any modules
obsolete?• Review usage of the system
• What forms are now obsolete?• What reports are not run?• Do we will use PLL / OLBs?
• Remove dead code - PITSS• Delete multiple copies of same sources• Merge forms that perform similar tasks

Why Upgrade Your Forms?• Ensure support (C/S de-supported
2004/10g Dec. 2011)• Certification – New browsers, O/S, Java
versions• New features - SOA, REUI, JavaScript• Strategic Middleware - Runs on
WebLogic • Upgrade is Seamless from 10g to 11g• Platform for integration

Suggested Work Plan• Backup ALL related files !!• Pilot Upgrade of application (50-100 forms)• Check forms for C/S or OS Specific features• Get an estimate of the work, time, cost• Clean up environment – unused, dead code• Modernize Look and Feel of the application• Freeze C/S - all new developments should be web • Do full upgrade in modules / Phases• Testing should be with each module!• Do Production Pilot (Phased rollout)

Forms Look and Feel Modernization• Toolbar and navigation
• Look and Feel Project• Color / Font / Size• Prompts / Titles• Images • Frames
• OLB, templates for visual standards

Look and Feel (LAF) Project• Dynamic LAF UI of Forms runtime.• Read from a CSS file then applied to the Forms
elements at runtime.• Have a more «HTML» look
Components• Set of Java Beans/PJCs
(laf_xxx.jar)• PL/SQL library (laf.pll) • External CSS file
![Page 22: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/22.jpg)
Yes - Java in Forms!Java Beans
– Java Bean Area - layout object on canvas– Use custom trigger to get and set properties
PJC – Portable Java Component– Change default behavior/properties of objects
Java Classes – Run webservices– Run Java code in forms triggers– Java importer – PLSQL java wrapper
JavaScript– Interact with objects in the browser page - Maps
![Page 23: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/23.jpg)

> Run external Webservices from within Oracle Forms triggers>Create a Web Service
proxy in Jdeveloper >Call the WS client from the Forms
application using the Java Importer

Javascript IntegrationTwo way client Side communication
![Page 27: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/27.jpg)
JavaScript Two Way JavaScript Communication > HTML page uses raiseEvent JavaScript method on
applet object to pass event with payload to the form
› document.forms_applet.raiseEvent(event_name, payload);>Trigger: WHEN-CUSTOM-JAVASCRIPT-EVENT
› Variables: system.javascript_event_value , name
> Form executes JavaScript in the browser › web.javascript_eval_expr_function › web.javascript_eval_expr
> JavaScript event handling can be disabled in the forms configuration files
![Page 28: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/28.jpg)
Javascript Integration> Communicate between forms and browser
page objects>web.javascript_eval_expr>web.javascript_eval_function – With return value
> JavaScript calls from Applet page (Forms object in the DOM ) into the form
>document.forms_applet.raiseEvent(event_name, payload);
>Two new forms system variables: > system.javascript_event_value (payload) > system.javascript_event_name (event_name)
>Oracle Forms fires new trigger called:WHEN-CUSTOM-JAVASCRIPT-EVENT.
> enableJavascriptEvent in formsweb.cfg to enable or disable JavaScript integration
> FORMS_ALLOW_JAVASCRIPT_EVENTS in default.env to override

Using Events in Forms
![Page 30: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/30.jpg)
Advanced QueuesHighly Available Asynchronous Communication >Messages are pushed to forms from DB msg queue
› New event object in forms builder attached to queue› WHEN-EVENT-RAISED trigger
>Code that should be initiated when a message is received in the subscribed queue
>Use DBMS_AQ package from within forms triggers› DBMS_AQ.ENQUEUE( queue, enqopt, msgprop,
payload, enq_msgid);
![Page 31: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/31.jpg)
Steps Required to Use Database Events:
> Database> Create a queue table> Create a queue> Start the queue> Enqueue a message
> Forms Builder> Create an event object> Subscribe event object to the queue> Code necessary notification
> Forms Server> Run the form and register the subscription> Invoke the When-Event-Raised trigger upon
event notification

What is AuraPlayerLeverage existing Oracle Forms systems
by … modernizing them to work in new
environments like Mobile, Cloud and SAAS

The Oracle Forms Modernization Challenge
Preserve Oracle Forms investments while …
– Enabling Forms business processes as WebServices in the cloud.
– Launching new ADF Mobile applications on Forms business logic
– Integrating with Oracle’s next generation development technologies – ADF, ADF Mobile, Webcenter Suite
– Running Forms silently from SOA / BPM systems– Creating collaborative applications – Dashboards,
Portals
… Avoiding risky and costly migration/re-development

Innovation By Migration
Things to Consider • This is a PROJECT. No silver bullet • Need a business reason to redevelop • Need thorough understanding of the Forms application• No tool can re-write your business logic• Need deep knowledge of the new technologies• UI implications – HTML vs Applet• Investigate 3rd party tools for migration assistance
Benefits of Migration• No Oracle Forms maintenance/licenses• Fully portable system• No applet, full HTML client• Larger developer pool
![Page 46: Mia Urman @ miaurman miaurman@AuraPlayer.com](https://reader034.vdocuments.site/reader034/viewer/2022052702/568167e3550346895ddd4a4c/html5/thumbnails/46.jpg)
“Forms isn’t dead it just smells funny”

Moving Forward Considerations For Modernization Projects • Asses Your Requirements
• What systems do we need to integrate with? UI requirements?
• What platforms do we need to deploy to?• Understand Your Existing System
• Where does the business logic sit today?• What functionality is duplicated in other systems?• Do we have documentation? Developer resources?
• Define Timeline and Budget• Decide on Implementation Method
• Integrate, Migrate, 3rd party solution

Summary• Clean up Forms environment – unused, dead
code• Upgrade to Latest version – Forms 11gR2• Modernize Look and Feel - Incorporate Java
elements• Chose right tool for the job• Refactor code to the DB • Systems on common infrastructure Weblogic –
SSO• Slowly evolve teams and systems• Start thinking about system INNOVATION – ADF
Mobile• Use AuraPlayer to move systems to the next
generation platforms / environments without migration
