7 “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 LN9P&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 State of the Union

8 CLEAN UP UPGRADE UPGRADEMODERNIZE INTEGRATE INTEGRATEINNOVATE! Game Plan: Game Plan: Leverage your EXISTING investment

9 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

10 CLEAN UP UPGRADE UPGRADEMODERNIZE INTEGRATE INTEGRATEINNOVATE! Game Plan: Game Plan: Leverage your EXISTING investment

11 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

12 Basic Architecture Forms 11g

13 WebLogic High Availability Topology WLS Oracle DB Oracle HTTP Server Load Balancer Internet Desktop Porafrm1,2,3 Poralnx

14 Forms Servlet Forms Services Architecture JRE Application logic layer Data manager/ PL/SQL engine User interface layer Forms Listener Servlet Forms Runtime Client tierDatabase tier Middle tier: WebLogic managed server UI rendered to client FMX containing app code Net Services Forms Client DB

15 Oracle Forms 9i/10gIAS Forms 11g WeblogicServer Forms 3.0 Oracle Forms 4.0 – 6i Client Server Upgrade RoadMap

16 Suggested Work Plan Backup ALL related files !! Pilot Upgrade of application ( 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)

17 CLEAN UP UPGRADE UPGRADEMODERNIZE INTEGRATE INTEGRATEINNOVATE! Game Plan: Game Plan: Leverage your EXISTING investment

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

21 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

22 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 wrapperJavaScript – Interact with objects in the browser page - Maps

23 Java Beans & PJCs

24 Java Importer Importing Java Classes into Forms

25 Webservices Call External Services From Forms 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; > 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

26 Javascript Integration Two way client Side communication

27 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

28 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

29 Using Events in Forms

30 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);

31 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

33 Hybrid Options Living Side By SideLiving Side By Side Forms running alongside new technologies Visual IntegrationVisual Integration Create a common UI – Forms & ADF/APEX/Java Process / Service IntegrationProcess / Service Integration Run common business logic DB/Events InnovationInnovation Run Forms business process from new environments - AuraPlayer

34 Forms & External Apps Living In Harmony Form System External System Security / Management Web.show_doc ument Common Bus Logic AQ Messages web.javascript_ev al_expr

35 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

36 Process / Service Integration Share Forms Business Logic – SOA / BPM Concept Reuse the business logic locked inside your Forms – Separate GUI from business logicImplementation Decoupling – Remove and Centralize bus logic to DB Events – Use AQ events for messaging

44 AuraPlayer Same Forms Business Logic Multiple UIs ADF Mobile

45 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

46 “Forms isn’t dead it just smells funny” Francois Degrelle

47 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, 3 rd party solution

48 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
