Today’s article in my series on zIIP processors will be a little different because I want to focus on a specific IBM mainframe pricing model and how users of that model may benefit from using zIIPs. The pricing model, Tailored Fit Pricing (TFP), is the latest model introduced by IBM. But what is TFP, and how does it differ from the sub-capacity pricing models used by most organizations? The Current State: Sub-Capacity Pricing Models IBM …

Your organization has taken the leap and chosen to modernize your existing COBOL monoliths into Java-based application services, ready for the cloud. Your team plots out a journey toward success. Rather than taking a risky big-bang approach, each incremental release on the road toward modernization is prioritized and scheduled to save costs and capture value that finances the next step. The automation factory starts to chew up old tables and churn out Java. The destination …

Over the past few months, I’ve written about the current state of specialty processors for IBM Z mainframes with a particular concentration on the zIIP. We looked at what they are, how they work, and why you might want to consider exploiting them. But in this article, I want to ruminate on the potential of specialty processors in the future. Before doing so, I want to strongly assert that I am not clairvoyant, so I …

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 …

Hopefully, you’ve been reading along in this series of articles on effective usage of the zIIP on the IBM System z mainframe. But even if you have not, this article focuses on a single topic that does not require in-depth knowledge of zIIP particulars. Herein we will discuss best practices for COBOL and Db2 users to bolster their usage of zIIPs. Why do this? As we have discussed in prior installations, the primary reason to …

In our previous writings, we’ve discussed the scale of COBOL investment over the last several decades and the challenges of continuing to depend on this legendary programming language. The drivers for modernization remain, and COBOL can’t help but be caught up in the plans of many mainframe organizations.  ANY modernization approach has risks associated with it. The volume of that risk is directly related to the number of components, programs, and applications that need to …

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 …

The debate as to whether you should or shouldn’t modernize any portion of your application portfolio is a separate question to the ways to do it correctly. While many people discuss “COBOL modernization,” there is much more involved than simply translating the syntax of COBOL to the syntax of another language. The keys to effectively modernizing COBOL applications must include considerations for maintainability, code quality, and computational precision. Transforming the syntax of COBOL to that …

Even though mainframes remain the transactional backbone of the modern economy, powering industries from banking to airlines, many enterprises with mainframes find their modernization strategies require migrating workloads off this platform into the cloud. Over the years, this requirement has led to a plethora of COBOL conversion applications that typically convert this venerable language into modern Java. If you’re looking to convert a COBOL program to Java, buyer beware: different approaches to such conversions with …

Our last post looked at the five significant benefits of Java and zIIPs, detailing how the combination can reduce cost, simplify support and maintenance, deliver the performance you need, and improve portability. But most enterprise mainframe applications are written in COBOL.  Now, most organizations are not likely to embark on a full-fledged campaign to convert all of their COBOL to Java. But converting some programs to Java can make sense if you use the proper …

It’s clear that the volume and importance of COBOL-based applications remains high. Despite the variety and volume of “stones” thrown by the modern IT intelligentsia at this language and the mainframe platform, these technologies continue to provide valuable solutions that answer the technology demands of many organizations.  The reason to address an organization’s existing portfolio of legacy applications isn’t that some enterprise architects – many of whom were trained solely in modern tech stacks – …

In this series of blog posts on the zIIP, we have looked at the various types of specialty processors and the zIIPs place among them, honed in on zIIP usage and eligibility issues and terms and examined the types of processing that can utilize zIIPs. Having digested all of that information, we will turn our attention to Java and take a look at the five most significant benefits it can bring to your environment. Before …

COBOL, arguably one of the earliest of the 3rd generation programming languages, is still used extensively. In particular, IBM mainframe platforms are still home to a significant number of applications originally developed in this language that continue to power many Fortune 500 companies today. Furthermore, several shrink-wrapped software packages, originally implemented decades ago in COBOL, are still used, e.g., PeopleSoft, emPath, Logo, Lawson ERP, etc. These facts are more a function of history than any …

Mainframe modernization can feel like a scene from Poltergeist, or any other thriller movie where the protagonist is trapped in an endlessly stretching hallway with a door that keeps receding into the distance. Ask anyone who’s survived a major enterprise upgrade. Transforming thousands of files and COBOL and JCL code into a form that will play nicely with modern Java architecture and cloud computing infrastructure seems to be an endless concern with few offramps. Even …

In our last installment of this series on IBM zIIP processors, we defined what is meant by zIIP eligibility. We took a look at specific types of workloads that IBM has made zIIP eligible. This post will dig a little deeper into what makes a workload eligible for running on zIIPs. And we will also take a look at why you would want to exploit zIIP processors for your workloads.  TCBs and SRBs To fully …

Organizations that want to modernize COBOL applications have a broad range of options, depending on their unique circumstances and vision of leveraging the intellectual property (IP) contained in the logic and processes of the applications. They usually consider three key factors: Cost, Risk, and Control. Some organizations may determine the application has little future value and modernize using a replacement strategy. Others may decide that the logic and IP have a great deal of value …

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 …

Migrating mainframe workload to the cloud entails more than simply a recompilation of code or transformation from one programming language to another. Mainframe applications are more than just an implementation of a business function in a particular programming language; the most common of which is COBOL. These applications have dependencies based on the platform’s unique data types and encoding architecture (EBCDIC) and the implementation techniques for batch and transactional workload that were established decades ago …

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 …

The never-ending and often contentious debate about the mainframe remains quite vocal in the marketplace. Whether it’s the technical mandarins of the mainframe shouting down anyone who challenges their core religious principles or the cloud intelligentsia looking down their noses at this 60-year-old platform, the arguments seem to show little sign of any reasonable compromise.  To clear the air: one can support the cloud without trashing the technology of the mainframe, and one can support …

Have you ever had a conversation with someone about moving applications to the cloud, and all you hear in response is how it won’t work? It reminds me of a funny movie in the 70’s set against the backdrop of WW II. Clint Eastwood leads a band of renegade soldiers on a hunt for gold. The tank commander, played by Donald Sutherland, always complains to his driver, played by Gavin MacLeod, about his negative attitude. …

Tell an IT leader or a developer that the world runs on COBOL applications, and they will nod their heads knowingly. That’s because the core systems of some of the largest brands and most critical industries still rely heavily on their legacy systems. With 92% of IT leaders reporting in a Vanson Bourne survey that their COBOL applications are strategic to their business, it’s paramount that these applications remain functional and supported. That’s a tall …

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 …
