When we talk about innovation being “leveraging or Exploring more values” from existing mainframe assets, Ivory Service Architect is doing an innovative job of this. That is exhibited clearly from my interview with Mr. Don Spoerke from GT software.
Current Business need
(i). Extending business obviously implies the extension of business IT Infrastructure in various channels such as
Application access thru Host
Application access thru Intranet
Application access thru Internet
(ii). Providing more sophisticated access to applications such as Pop Up windows, Scrolling and Drop down lists will make the user interactions with the application more user Friendly and customers can get used to them without any additional training. This is more vital when self service applications are driven/being used by more walk-in customers. They can’t easily get to use mainframe host screens and complete their transactions.
What is the cost effective way of extending the business applications is the question to modern mainframe SOA architecture.
Current world scenario
In today’s world, more enterprise systems are using 3270/5250 mainframe screens to access their core transaction systems/batch applications. Traditionally, it requires more personnel training & infrastructure cost to host access.
Especially, core transaction processing applications developed in Mainframe applications are decade long investments and have millions of code which implies the business applications stability & rich features.
Extending these applications \ to accommodate the current business requirements is the business need of the hour.
Ideal world scenario
Users can access the applications using the web based interfaces or Graphical interfaces which provides more application extension in more channels and easy accessiblity.
In the changing world, the Ivory Service Architect server in Z/OS provides the applications to be accessed using the web services.
Using “Ivory Service Architect”, mainframe application flow can be converted/exposed as a web services. This will be accessed as a web services from various internet browser applications. Exposed WSDL files can be used by Java /.Net clients.
Applications running under CICS or IMS can be exposed as web services.
What is needed to be changed in Infrastructure/Applications?
(I). Server perspective
Ivory Service Architect server provides the runtime environment for the web services which were created using the mainframe applications. Ivory Service Architect server can run in CICS/TS, as a z/OS started task, Linux on Systemz, Linux or Windows.
(II). Application change perspective
There is no need to change existing applications or programs. Required application flow as it stands can be extracted as a web service. The only change or development effort needed will be new interfaces such as websites and other web applications depend on the current existence.
(III). Ongoing maintenance perspective
When application program COMMAREA/ input / output parameters change, the respective web services can be maintained and redeployed using the same graphical Ivory Studio in which they were created.
(IV).What skills required
No special technical skills/XML knowledge required to generate web services. Existing analysts who are familiar with application flow will be able to generate the required web services.
What is needed in training for professionals (Application users)
New world Applications will represent the same functionality in new interface with more usability. So no extra training required other than providing the URL where to access the applications. The adoptability should be easy to adopt.
