Then Next ….
State of the Union
“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 2012
http://www.oracle.com/technetwork/issue-archive/2010/toolssod-3-129969.pdf
“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. 2011

Clean Up
Don’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
Game Plan:
Leverage your EXISTING investment
CLEAN UP
UPGRADE
MODERNIZE
INTEGRATE
INNOVATE!
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)
Game Plan:
Leverage your EXISTING investment

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
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
Java Beans & PJCs
Java Importer
Importing Java Classes into Forms
Webservices
Call External Services From Forms
> Run external Webservices from within
Oracle Forms triggers
>Create a Web Service
in Jdeveloper
proxy
>Call the WS client from the Forms
application using the Java Importer
package CurrencyConverter
/* currconv3.mypackage.CurrConv3Stub */ IS
function new
return ora_java.jobject;
function
getrate( obj ora_java.jobject,
a0 varchar2, a1 varchar2)
return ora_java.jobject;
end;
Javascript Integration
Two way client Side communication
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
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
Advanced Queues
Highly 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);
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

Hybrid Options
• Living Side By Side
Forms running alongside
new technologies
• Visual Integration
Create a common UI –
Forms & ADF/APEX/Java
• Process / Service
Integration
Run common business logic
DB/Events
• Innovation
Run Forms business process
from new environments -
Forms & External Apps
Living In Harmony

What is Visual Integration?
Portal \ Unified Desktop \ Dashboards
Concept
• Integrating Oracle Forms and Other
Technologies Into a single user
experience
• One point of access - SSO
• Customized based on users business
needs
Implementation
• iFrames
• Javascipt
• guiMode – Remove menus
Process / Service Integration
Share Forms Business Logic – SOA / BPM
Concept
•
Reuse the business logic locked inside your Forms –
Separate GUI from business logic
Implementation
• Decoupling – Remove and Centralize bus logic to DB
• Events – Use AQ events for messaging

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

Customer Story
AuraPlayer
Same Forms Business Logic Multiple UIs
ADF Mobile
Innovation By Migration
Benefits of Migration
•
•
•
•
No Oracle Forms maintenance/licenses
Fully portable system
No applet, full HTML client
Larger developer pool
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
“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
