Incremental Modernization

The Value of Incremental Modernization for COBOL Applications Portfolios

The concerns facing businesses regarding COBOL modernization are issues that have been created over five decades. This is more than enough time for inherent and potentially unseen variables to develop, and those issues shouldn’t be so quickly dismissed. Yet, there is a perception that a complete and total replacement is a single-step process! Reduced Risk The risk of completely rewriting applications seems appealing to those who don’t understand the value of COBOL or who view

Common zIIP Usage Mistakes and How to Identify Them

Many organizations using the IBM System z have begun to use zIIP processors to help reduce the overall cost of their mainframe environment. But… Assuming Everything Will Run on the zIIP One of the biggest mistakes you can make is assuming that everything that is eligible to run on the zIIP will actually run on the zIIP. Although this may seem like a reasonable assumption, it neglects to take into account what is sometimes referred

Digging Into the zIIP: What Does zIIP Eligible Mean?

In the first article in this series on mainframe specialty processors, the zIIP is an “information” processor, where the IIP in its name stands for Integrated Information Processor. When the zIIP was introduced by IBM in 2006, DB2 Version 8 was the first subsystem to take advantage of the zIIP. Over the course of the ensuing years, IBM (and other vendors) have enabled additional workload eligible to be redirected to the zIIP. It stands to

How to Build a COBOL Modernization Factory

Modernization of legacy systems can be an essential enabler of any digital transformation effort – or a frustrating roadblock impeding all meaningful progress with digital efforts. For enterprises with hundreds or even thousands of mainframe-based COBOL applications, the modernization challenge can seem insurmountable. Such applications have accumulated over the years, the result of generations of COBOL developers with different backgrounds and skillsets responding to an ever-changing set of requirements. While retiring the lot and starting

Understanding Mainframe Specialty Processors: zIIPS and more

If you are an IT professional who works on IBM z Series mainframes, then you’ve probably heard about zIIPs and other “specialty processors.” But you may not really know what they are, what they do, and why they exist. With that in mind, let’s take a brief journey into the world of specialty processors. Starting in the early 2000s, IBM has introduced several different types of specialty processors. The basic idea of a specialty processor

Why Incremental Modernization Reduces Risk and Increases Success

The coronavirus pandemic heightened the value and importance of digital adoption. As a consequence businesses have been accelerating their digital transformation plans by three to seven years. This includes mainframe modernization plans. While the breadth and depth of transformation are unique to each organization, components of transformation: processes, alignment of business and IT resources, responsiveness to customers, and changes to the supporting IT assets are consistent. The IT assets involved in this effort are said

Three Reasons It Makes Sense to Convert Some of Your COBOL to Java

Mainframes continue to be viable for enterprise computing due to their inherent capabilities for supporting the most critical business functions. When it comes to supporting large volumes of data, high-speed transaction processing, and secure computing the mainframe continues to excel. The Fortune 1000 relies upon mainframes to run their business, and of course, much of […]

Live Transformation: Maintainable Java from COBOL in 60 Minutes

Live Transformation: Maintainable Java from COBOL in 60 Minutes

When you hear “COBOL transformation to maintainable Java in 60 minutes” the reaction is predictable; eye rolls, thinking – “yeah right,” and suspicion.  It’s understandable that you have a healthy skepticism when it comes to COBOL transformation pronouncements.  After all, COBOL has been on the “replace” list for decades, and stories of failed projects are […]

From A to zIIP: What you need to know to reduce COBOL Costs with the IBM Specialty Processor Now Available on YouTube

From A to zIIP: What you need to know to reduce COBOL Costs with the IBM Specialty Processor Now Available on YouTube

The zIIP, an IBM specialty processor, allows organizations to reduce the workload of their general processors (GPs).  This reduction can lower the MSU metrics used to calculate MLC software charges.  Lower MSU usage can lead to lower MLC charges. Knowing that zIIPs may reduce your cost and achieve the benefit isn’t as complicated as you […]
