Modernization Lessons: FTP & the Mainframe

Clayton Neff Consulting, Java, Problem Solving, Programming, Spring Batch, Technology Snapshot Leave a Comment

One of my most recent projects involved helping a client move many decades of code from a mainframe environment to a distributed Java web environment. The client had engaged another company to actually transform the mainframe code to Java, and our team was tasked with making it all actually work.

One of the major areas we had to deal with was the transition of all of the batch processes. Of course, Spring Batch came to our rescue for most of the work, and was an easy choice as we were already using Spring Boot to wrapper the converted applications.

The most challenging part of the entire project was that the client did not want to move everything at once in a Big Bang, but rather a few programs as a time. This meant that some programs would be running in the Java environment while others remained on the mainframe.

In this blog, I discuss three data challenges we encountered in the transition of an enterprise mainframe to Java web application with Spring Batch, how we overcame them, and tips to keep in mind going forward when in similar migration situations.

Programming Ponderings

Editor’s Note: After nearly 20 years in software development, Ryan LaRue introduces three lessons he has learned in his programming career with takeaways that apply to all levels of experience.

Open Door Policy
One of the reasons I’ve always loved Software Development is its open door policy to new entrants. No MBA, PhD or, heck, degree required.

If you’re smart, like to solve problems, and get things done, then you will be welcomed with open arms.

At a recent client, one of the company’s permanent developers was, in her near-term past, a police officer. At some point, she decided she didn’t want that lifestyle anymore and worked her way into a nice position with a company that valued her work ethic and programming skills….



Event Storming For Rapid Domain Learning

John Hoestje Agile, Consulting, Dev Methodologies 1 Comment

Tl:dr: Use Event Storming to rapidly gain group understanding of complex business domains while having a more enjoyable time.

While I was browsing tech news sites looking for articles, a headline caught my eye talking about domain-driven design (DDD). Its main idea was to implement Event Storming to drive the understanding of the business domain. The more I read about it, the more I saw the value in what Event Storming offered.

On a recent consulting project, we were piloting Agile in a Waterfall environment, so in reality, any requirement gathering process used would have been new. We chose to compare Event Storming to User Story Mapping, allotting just one hour to work with each process. The process that the pilot Agile team favored would then be used going forward.

In this blog, I will share the main takeaways and benefits that became apparent while implementing Event Storming sessions, especially as compared to User Story Mapping. I will first explain the project we worked on and underlying opinions that drove our trial, what key aspects of Event Storming stood out to us, and then tips I picked up along the way for effective Event Storming sessions….

Adventures In Modernization: Strategy + Example Converting COBOL To Java

Dallas Monson Consulting, Java, Keyhole Creations, Programming, Technology Snapshot, Tutorial Leave a Comment

We have consultants who specialize in moving old to new, renovating dilapidated code bases, and designing brighter futures for enterprises who have been vendor-locked for most of their existence. We have come across some repeated patterns and strategies for how to approach modernization of legacy systems. In this blog, we will cover a strategy that is very popular right now, Re-Platforming.

The basic flow of this post will be:

Introduction to Modernization
High-level definition of the Re-Platforming Strategy for Modernization
Sample of Re-Platforming using Keyhole Syntax Tree Transformer, COBOL –> Java
Additional thoughts on the value/risk of this strategy

Let’s get started…
