Agenda § § § § Introductions and topic review State of the Forms landscape Your options Upgrade? Modernize? Which is right for you? Why Modernize? Forms to Fusion Mapping ADF v 11 Closing and Q&A © Vgo Software, Inc. 2008 www. vgosoftware. com
Introduction Vgo Software, Inc. § § § § Software and services to modernize Oracle Forms to JEE or upgrade Services to modernize Power. Builder, VB and ASP to Oracle ADF 1 of 2 global partners certified by Oracle product development 1 st to modernize Forms to ADF v 11 1 st in the world to automate the conversion of characterbased telnet forms Software and services based on 4 years of experience in conversions (25+ conversions) International customers and partners Started from NEOS – practical consulting © Vgo Software, Inc. 2008 www. vgosoftware. com
The Forms Landscape Are Forms going somewhere? No! (Well, maybe…) § Oracle Forms 2008 de-support § § v 6. 0. 8. x sustained support ended in January 2008 9. 0. 2. x sustained support ended in July 1 2008 10 g. R 2 extended support ends December 2011 10 g. R 3 extended support ends December 2011 § § § http: //www. oracle. com/support/collateral/lifetime-support-coverage-chart. pdf Forms continuing on until at least 2013 Forms community is alive, well and strong © Vgo Software, Inc. 2008 www. vgosoftware. com
Forms Landscape But… Oracle is moving to ADF – you will too § § § Think about it… what is “Fusion”? It’s important for Oracle’s continued growth strategy – it’s how they will integrate acquired products and those they’ve grown What’s the “glue”? ADF – BPM Studio, BPEL, a new (better) Enterprise Message Bus (Aqua. Logic Service Bus), etc. © Vgo Software, Inc. 2008 www. vgosoftware. com
Impact What does this mean? § § § If you are not running Oracle Application Server (or Weblogic), you will need to Get up to speed now – prepare for change Oracle Applications users – Apps are being migrated to ADF now; your custom extensions will have to move too Resources – where will all the Forms developers be in 2012? This may not be a “simple” change for developers – it is a paradigm shift © Vgo Software, Inc. 2008 www. vgosoftware. com
Options q Upgrade to Web Forms q Modernize, re-engineer… evolve q Re-write q Buy a commercial package © Vgo Software, Inc. 2008 www. vgosoftware. com
Which Option is Right for You? q Upgrade Forms when… The application cannot change at all – Cost is a huge issue – You need to stay supported (6 i users) – q Modernize to ADF when you require … Greater ability to integrate with other applications – Greater cross-platform support – See next slides… – q Re-write when. . Business processes need to dramatically change – Forms are really old (v 3) and code is unclear – You have unlimited budget – © Vgo Software, Inc. 2008 www. vgosoftware. com
Modernization & Business Value q Why Modernize? § Address tactical challenges while positioning for a long-term strategic operations architecture. Consider: – Vendor direction – Availability of skilled resources in legacy technology – Ability to maintain SDLC maturity levels in “aged” and “new” paradigms • Greater efficiencies in IT support of business changes – Lower TCO of the enterprise and single LOB (line-of-business) applications through common architectures and development patterns – Faster turn-around on functional enhancements – Greater flexibility to business demands – Common, flexible, development methodologies and processes © Vgo Software, Inc. 2008 www. vgosoftware. com
Modernization & Business Value q Why Modernize? (continued) § Application and/or data integration – SOA or EAI – Integration and cross-application rules sharing or re-use – Consolidation and management of (previously) disparate architectures – file transfers, client/server apps, EDI, etc. “All AD (Application Development) organizations should plan to migrate away from Oracle Forms applications during the next 10 years… All but the mostconservative of AD organizations should plan to migrate during the next five years. ” Mark Driver, Gartner RAS Core Research Note G 00146666, July 3, 2007 © Vgo Software, Inc. 2008 www. vgosoftware. com
Modernization & Business Value q Why do these efforts fail? § § § Under-estimation of effort – blown budgets Lack of planning No business participation “Blind” conversion Lack of Experience © Vgo Software, Inc. 2008 www. vgosoftware. com
Pre-Modernization Thoughts q Prior to any modernization or re-engineering project, effort should be extended to: Consider strategic direction and business value § Develop your “Conversion Framework” § § § Assessments, domain analysis, function point analysis, design, QA, etc. Application “domains” § Client, Producer, Product, Agent, etc. Emphasize re-use and process § Make “High-Leverage” Enhancements § Think ahead – where and how does this tie in strategically? § © Vgo Software, Inc. 2008 www. vgosoftware. com

Why ADF v 11? q ADF Business Components Data caching – Transaction handling via Task Flows – q ADF Rich Faces Ajax-enabled components – JSF-based – q JDeveloper Lots of wizards – Less coding – © Vgo Software, Inc. 2008 www. vgosoftware. com
Forms to ADF q Model Layer § Tables Entity Objects – 1 per Table – Can be used to implement validation triggers – Validation occurs no matter where Entity is used § View Objects § View Links and Associations § § Query-based blocks View Objects Based on one or more entities § May be linked to other views § Views may include other views or entities – description fields and LOVs § © Vgo Software, Inc. 2008 www. vgosoftware. com
Forms to ADF q Model Layer § LOVs read-only View Objects – – § Built using SQL statements – very much like a block in Forms Why “read-only”? § Performance § Functionality ADF BC Browser – © Vgo Software, Inc. 2008 Test model layer § Validations and LOV’s www. vgosoftware. com
Forms to ADF q View. Controller Layer Forms Task flows § Windows & Canvases – Windows become separate JSPX pages – Canvases become mutable Panel. Groups § § © Vgo Software, Inc. 2008 Hide/show each Panel. Group as application navigates between canvases (uses Render tag and a managed bean) www. vgosoftware. com
Groovy q What’s so groovy about § Based on Java and used in many projects – – Open source expression language Competitor is Rails-Grails Included in ADF v 11 § In ADF, Groovy scripts can be used in any application layer § Validation on the presentation layer (hide/show, allow/prevent) – Foreign key checks on the Entity – Access Application Modules, views, etc. – © Vgo Software, Inc. 2008 www. vgosoftware. com
What Doesn’t Map? q Client-Server != Web § Many aspects of a Forms application can’t be replicated exactly in the web world Win. API Calls – File-system or Registry access – Synchronize, etc…. – § Many aspects of a Forms application should be reimplemented or converted Declarative validation – LOVs – © Vgo Software, Inc. 2008 www. vgosoftware. com
ADF in JDeveloper 11 g Big performance enhancements q BEA Weblogic in; OC 4 J out q Look and feel of ADF Faces Rich Client components has been updated q Fixed problems with LOV q LOV in Create form with Mandatory fields is fixed § LOV wizards are improved § Some are not: LOV bug re-presenting selected value § q Most major issues from TP 4 have been resolved § q Such as Oracle Java Platform Security (JPS) This is a Jdeveloper release; rest of 11 g coming in January © Vgo Software, Inc. 2008 www. vgosoftware. com
Summary q q q Upgrade for safety and ease Modernize and evolve when positioning for strategic advantage Always consider your process in either type of project – leverage new architectural advantages ADF v 11 will be the correct go-forward answer for Forms modernization and other client/server applications Think outside of the Forms silo – what is the value to the business and to the enterprise? © Vgo Software, Inc. 2008 www. vgosoftware. com
