View of the market today

Many organizations worldwide still maintain business critical applications based on legacy Oracle Forms. Why?

Oracle Forms a popular development framework for 2 decades, high customer satisfactionCore business / mission critical applications built in FormsHeavy investments on Forms through many yearsRobust applications still workNo out-of-the-box replacement availableRe-writing too expensive and takes years to complete

Many ISV products need to be modernized (Business Driven)Customer drivenCompetition driven


View of the marketDecline of Oracle Forms

Business processes have changed to meet new challengesInternet business community demands moreRemote access, Fast response,Extend application to do moreExpose application to partners and customersEasy maintenance, portability, database independenceMore performance for less money

Modernize these legacy applications in order to leverage the internet. How?

Rewrite?Replace?Web-enable Forms (upgrade to 10g)Automated migration of is the answer

Open computing ─ a new route to collaboration and innovation

Open standardsImprove data sharing by simplifying integration of disparate technologies

Open architectureIncrease collaboration by easily extending business processes

Open sourcePromote innovation by leveraging community development

Open architecture

Open standards

Opensource

Open computing


A powerful Object Oriented Programming language

The "most open" product that is available, conforming both to its own standardized (and published) specifications as well as with other industry standards such as CORBA

JDBC (Java Database Connectivity) provides a standardized interface for Relational databases for Java, providing a greaterlevel of database independence and portability

Can eliminate costs/support of proprietary licensing

Platform & Database independence

Open Computing - Java


Open Computing - Java is superior

Java is currently the only technology that provides a fully interactive, GUI interface for the Web

The Java architecture was designed with security in mind, and not as an afterthought. This provides a simplified and consistent means of protecting your assets.

Java provides features that make programming easier as well as more powerful

• multi-threading capabilities• automatic "garbage collection" (for efficient use of memory)• standardized error trapping and detection• distributed processing capabilities


Business Driven Factors – IT TrendGeographic distribution of business─the new norm

Near-shoreInternal staffingDirect ownership

Offshore – China/MacauSubsidiariesJoint partnershipsDirect ownership of foreign facilities and hiring of employees

Rewrite ApplicationProgrammers often want to throw away code and start over. Why? The cardinal fundamental law of programming: “It’s harder to read code than to write it”.

Programmers tend to write their own functions because it's easier and more fun than figuring out how the old function works. However, old code has been used, tested, and bugs have been found and fixed

Web-enable FormsEasy - No change to development styleNot a “real” migration

Manual conversionTime consuming, design own architecture from scratch, human error issues, lack of resources or skill set, disruptions to business operations, escalating costs

Automatic conversionTrusted architecture, cost efficient, less time intensive, manages risks, less errors, much faster

Source Code Migration Options


Fully maintainablePortableContains no wrappersAll semantic contents convertedFlexible deploymentVery little impact on business operations

Goals for Automatic Conversion


Integration option - to integrate with Open Computing development environment including:

Full integration with Eclipse IDE and Rational

Utilization of Linux and Tomcat/Apache environment

Assists in moving applications from Oracle Forms or later releases into SOA environment

Provides efficient way to get Forms, Libraries, and Procedures into Open Computing environment

Goals for Automatic Conversion


N-Tier ArchitectureJ2EE CompliantXML DrivenGeneric GUI GenerationProvides clients with the option to integrate with Eclipse IDE or become database independent

Demonstration


To ensure that the migration is being converted to a true Java or J2EE environment, you should ask the following questions:

• Is my application being converted to truly compliant J2EE code?

• Are we able to purchase the tool, or is this a service offering only?

• Where is my conversion to be performed (on-site or at the client's site)?

• Are we able to discontinue licensing of Oracle Forms and PL/SQL or do I still have to license these products?

Important Migration Questions


• Is the vendor offering the product or service available to assist with any issues and training once we migrate to Java?

• What percentage of conversion is automatic (how much manual work is involved once it is converted)?

• Is the J2EE code "clean", i.e., is it easily maintainable once I get into the Java environment?

• Does the converted code integrate with Open Java IDE and utilize native Tomcat and Apache environment?

• Does the converted code allow you to become database independent?
