About the Application

Challenges: Big Forms application that needs

to run on supported platforms

Part of modules need to run on legacy hardware: Windows CE 5.0 barcode scanners of various types

Forms 11g does not run on Win CE 5 devices

Maintaining the old INPs only for

the mobile devices was not an option

Our Technology Options for the UI

Oracle ADF 11g Mobile Overview

“…HTML5 and Java-based mobile application development framework that enables developers to build and extend enterprise applications for iOS and Android from a single code base. Based on a hybrid mobile architecture, ADF Mobile supports access to native device services, enables offline applications and protects enterprise investments from future technology shifts. Oracle ADF Mobile is part of Oracle ADF, the strategic, standards based framework for Oracle Fusion ...”

Top Issues ADF Mobile Browser needs

JavaScript for function keys. JavaScript browser not available for Windows CE 5.0

ADF Mobile not supported for Windows CE 5.0

Our Technology Options for the UI - The Win CE JavaScript Problem

The research process took 2 weeks!!! => 6 weeks left for migration!!


The Solution

Thin client Key-Functions Full-screen (Kiosk) Modern UI Compatible with existing devices Thick (90%) ADF + DB Preserve DB Communicate with the rest of the Forms

Our Technology Options for the UI


The Solution: Forms & ADF Server + .NET Client

.NET: • Compact Framework 2.0 SP 2.0 Web Services • JAX-WS • Login/ Authentication

ADF: • JDeveloper 11.1.1.6 • Weblogic: ADF Runtime 11.1.1.6

Database: • Oracle 11g • Packages created from Forms functionality

• Without unused objects • Grouping redundancies for easier maintenance • Cleaned from any global variables and global

transactions => connection sharing

The 6-weeks Migration Work

Our solutions for managing time : Make accurate estimations Avoid surprises, at least the bad ones How: analyze in detail to know exactly what to do, use analysis tools But avoid paralysis by analysis Have and follow a clear process plan

Biggest Challenges: TIME = Meeting the end April deadline INTEGRATION = Making technologies work together

Navigation = Call_form, open_form…


Making accurate Time Estimations

Challenge: How to put numbers

behind individual modules?

Forms Modules vary in size

Modernization tasks vary in complexity among

projects

Know-how varies among project teams

PITSS.CON Complexity Analysis Report

Estimating total application complexity

Breaking down to individual modules

And individual project phases


In average, 30% of Forms objects are unused or redundant

What to do with the unused code?

A. Leave it there (Never touch a running system)

B. Move unused code to database (Out of sight)

C. Dare to delete it

What we did:

deleted unused objects

grouped similar code in libraries

moved data management to DB

Application Cleaning: PITSS.CON Unused Objects Analysis

Identifying and eliminating unused code from the start saves time and allows us to estimate work accurately. The Java/ .NET developer does not need to figure out what to do with that code.


Reducing Redundancies

Forms Objects/ Business Logic

→ Components Reuse → Modularity

30% match

100% match 70% match

100% match

70% match

50% match

Moving logic to DB is a good opportunity to consolidate code and avoid repetition. We identified redundancies with PITSS.CON and then consolidated in flexible, parameterized DB functions and procedures.


In typical Forms applications we can move easily 30% of the logic to DB.

In this project we moved 90%.

Architecture benefits:

reduced size, maintenance

increasing code reuse

Difficulty: separating DML from UI:

DML to DB

and UI to ADF/.NET

Business Logic to Database: PITSS.CON BL Assistant


Analysis Tools: Data Management Flow (generated with PITSS.CON)

=> we implemented it as standard PITSS.CON feature and gained time

Vital analysis for ADF/ .NET developers

DB Tables

Blocks

Triggers

Functions procedures

Time to generate manually: 1 day per FMB module


ADF Web Services Architecture

JDeveloper 11.1.1.6 Weblogic: ADF Runtime 11.1.1.6

Web services: standard Oracle ADF components Challenges: - Connection Pooling - Multiple databases for each WebLogic Server

(the server selects the suitable connection depending on device and user)

- Database-defined multi-language (shared across different applications and technologies)

YES!! Definitively! “Stressful? Yes. But clearly the most challenging and interesting project in the last years.”
