State of the Mainframe 2018



Every year BMC Software conducts a survey of mainframe usage that provides a unique insight into the trends, topics, and over outlook for mainframe computing. And every year I look forward to digesting all of the great information it contains. The results were presented in a webinar on September 19th (the date of this post).
This year’s survey contains responses from over 1,100 executives and technical professionals ranging in age from 18 to 65+ years old, and with experience levels of 30+ years to less than a year on the job. People were surveyed across a multitude of industries, company sizes, and geographies. And the consensus is that mainframe is key to the future of digital business.
At a high level, the survey indicates that we are working to scale and modernize the mainframe to support new business. And part of that is embracing DevOps practices in the mainframe environment to optimize application delivery.
With a heritage of more than 50 years of driving mission-critical workloads, the mainframe continues to be a powerful and versatile platform for existing and new workloads. Yes, organizations are embracing the mainframe for the new world of mobile computing, analytics, and digital transformation. And that include modernizing mainframe applications because critical apps continue to grow in size and importance. Modernization efforts range from increased usage of Java to API development and encrypting sensitive data. And 42% say that application modernization is priority.

The mainframe’s strengths are many, as this survey clearly shows. Year after year, mainframe strengths have included high availability, strong security, centralized data serving, and transaction throughput – and those strengths were again highlighted this year. But a new strength this year is that new technology is available on the platform. It is clear that IBM’s hard work to ensure that the mainframe can be used with new technology has succeeded and respondents acknowledge its adoption of new stuff while keeping the heart of the business running.
There are a lot of these types of insights in this report, and you should definitely download the report and read it yourself. But here are a few additional highlights that I want to make sure you do not miss out on reading about:
  • Executives (93% of them) believe in the long-term viability of the mainframe.
  • The mainframe remains as the most important data server at many shops. 51% of survey respondents cite that more than half of their data resides on the mainframe.
  • And most of the primary growth areas are trending up in terms of mainframe growth. Mainframe environments are handling significant increases in the number of databases and transaction volumes as well as an increasing trend in data volume.



And 70% of large companies are forecasting that the mainframe will experience capacity growth over the course of the next 2 years.

Of course, challenges remain. According to the survey the top three challenges are the same as they have been recently: cost control, staffing and skills shortages, and executive perception of the mainframe as a long-term solution. So we, as mainframe proponents need to keep banging the drum to get the word out about our favorite, and still viable, platform for enterprise computing – the mainframe.
So download the survey and read all about the state of the mainframe 2018… because the future of the platform is bright, and it will only get brighter with your knowledge and support.

The IBM z14: There's a New Mainframe Coming!

Today, July 17, 2017, IBM announced the next iteration of its stalwart mainframe hardware, the IBM z14. The news comes a little more than two years since the previous version, the IBM z13. The hardware will be generally available later this year.



The big news is that IBM delivering pervasive encryption as part of the IBM z14. With pervasive encryption you can encrypt and protect all of your data all the time, at any scale, without having to change any application code or do any development work. That means you can protect all of your data without requiring an interruption to your business.

The IBM z14 features the industry's fastest microprocessor, running at 5.2GHz, and a new scalable system structure that delivers up to a 35 percent capacity increase compared to the previous generation z13. The system can support over 12 billion encrypted transactions per day on a single system.
Other new capabilities of the IBM z14 include up to 32 TB of memory (3x the memory of the z13), three times faster I/O, and a 10x latency reduction with SAN response time using zHyperLink.
IBM also has introduced three new pricing models to help reduce the cost of mainframe computing, specifically for development and testing, new application workloads, and payment processing.
All in all, with the announcement of the IBM z14, IBM is doing what it takes to make the best computing platform even better. I look forward to using the platform and seeing what it can do for high availability, high performance, secure computing!

Happy Birthday Mainframe!

Fifty Two Years Ago This Week

On April 7, 1964, IBM announced "a new generation of electronic computing equipment" called the IBM System/360... or as it, and subsequent generations of the machine have become known, the mainframe!


If you'd like to take a walk down memory lane you can read the original press release on the IBM web site.

The System/360, unquestionably, was one of the most significant products in the history of computing. The general, sound concepts of the System/360 are still the at the foundation of modern mainframe. Sure, a lot has changed, but those changes were made to a solid, fundamentally sound base.

Code that ran on the System/360 can still be run on the latest and greatest modern IBM mainframe, the z13. What other platform can say that? I mean, when my desktop was recently force upgraded from Windows 7 to WIndows 10 some of my software stopped running!

So let's take a moment and salute the mainframe on its 52nd birthday... and wish it many more years of productive use.

Happy birthday, mainframe!

Mainframe Cost Optimization



Modern businesses live in an age of financial austerity, cost containment and cutbacks. It is just a fact of life in many organizations that you need to be constantly vigilant for new ways to reduce costs. If your business relies on the mainframe -- and many of the biggest businesses do -- cost containment is of the utmost importance.
But how to cut costs? Many mainframe support groups are running thin in terms of people - so layoffs don't make a lot of sense. And the software that runs the business can't be cut. Management software supports the business systems, so cutting those may cost more than you save!

But there are things you can do. If you're interested in learning more about IBM MLC software costs, pricing/licensing, mainframe cost optimization and a solution to dynamically manage your system to reduce software costs be sure to take an hour out of your busy schedule and join me for a free webinar titled Mainframe Cost Optimization: Pricing, Licensing, the R4HA, and More! 

I'll be delivering this webinar on September 10, 2015 at 2pm EDT.

During this session I'll discuss:
  • The new mainframe pricing options including zCAP, CMP and MWP
  • The disparate moving parts of sub-capacity pricing including the R4HA
  • Methods for controlling R4HA intelligently to reduce monthly software costs.

So click here to register for the webinar and join me on September 10th.

IBM Announces New Mainframes

IBM today announced their latest model mainframe, the IBM z13.



Everybody knows -- or should know -- that the mainframe is the work horse of the IT industry, but the new z13 boasts some amazing capabilities. The z13 can process 2.5 billion transactions a day. And those transactions are persistent, protected and auditable end-to-end!  Furthermore, the z13 delivers practical real-time encryption based on 500 new patents, including advanced cryptographic encryption technologies. And the z13 comes with embedded analytics capabilities.

“Every time a consumer makes a purchase or hits refresh on a smart phone, it can create a cascade of events on the back end of the computing environment. The z13 is designed to handle billions of transactions for the mobile economy.  Only the IBM mainframe can put the power of the world's most secure data centers in the palm of your hand," said Tom Rosamilia, senior vice president, IBM Systems.

To put this amount of power into context, IBM notes that a single z13 mainframe can porcess more than 30,000 transactions per second, which is roughly the same as 100 Cyber Mondays every day!



IBM has designed the z13 to integrate real-time scoring and guarantees this capability as a feature of the system. This scoring can be used for fraud detection on 100 percent of a client's business transactions. To take advantage of this capability customers must be running the latest versions of DB2 and SPSS Scoring Adapter on z13 machine, as well as following IBM's capacity planning implementation instructions and processes.

For the long-time mainframe zealots out there, of which I am one, it always gives me a warm feeling inside when IBM comes out with a new line of mainframes. The mainframe always leads the IT industry in terms of processing power and capabilities... and it looks like it will continue to do so well into the future...

A Short Report from SHARE in Pittsburgh

Today’s blog post will be a short review of SHARE posted directly from the conference floor in Pittsburgh!

What is SHARE
For those of you who are not aware of SHARE, it is an independent, volunteer run association providing enterprise technology professionals with continuous education and training, valuable professional networking and effective industry influence. SHARE has existed for almost 60 years. It was established in 1955 and is the oldest organization of computing professionals.
The group conducts two conferences every year. Earlier in 2014 the first event was held in Anaheim, and this week (the week of August 3rd) the second annual event is being held in my original hometown, Pittsburgh, PA. Now I’ve been attending SHARE, more regularly in the past than lately, since the 1990’s. But with the event being held in Pittsburgh I just had to participate!
The keynote (or general) session today started up at 8:00 AM. It was titled “Beyond Silicon: Cognition and Much, Much More”  and it was delivered by Dr. Bernard S.Meyerson, IBM Fellow and VP, Innovation.  Meyerson delighted the crowd with his entertaining and educational session.

Next up was “Enterprise Computing: The Present and the Future”, an entertaining session that focused on what IBM believes are the four biggest driving trends in IT/computing: cloud, analytics, mobile, and social media. And, indeed, these trends are pervasive and interact with one another to create the infrastructure of most modern development efforts. Bryan Foley Program Director, System z Strategy at IBM delivered the presentation and unloaded a number of interesting stats on the audience, including:
  • Mainframe is experiencing 31 percent growth
  • Mainframes process 30 billion business transactions daily
  • The mainframe is the ultimate virtualized system
  • System z is the most heavily instrumented platform in the world
  • The mainframe is an excellent platform for analytics because that’s where the data is

Clearly, if you are a mainframer, there is a lot to digest… and a lot to celebrate. Perhaps the most interesting tidbit shared by Foley is that “PC is the new legacy!” He backed this up with a stat claiming that mobile Internet users are projected to surpass PC Internet users in 2015. Interesting, no?

Now those of you that know me know that I am a DB2 guy, but I have not yet attended much DB2 stuff. I sat in on an intro to MQ and I’m currently prepping for my presentation this afternoon – “Ten Breakthroughs That Changed DB2 Forever.”


The presentation is based on a series of articles I wrote a couple years ago, but I am continually tweaking it to keep it up to date and relevant. So even if you’ve read the article, if you are at SHARE and a DB2 person, stop by Room 402 at 3:00PM… and if you’re not here, the articles will have to do!

That's all for now... gotta get back to reviewing my presentation... hope to see you at SHARE this week... or, if not, somewhere else out there in DB2-land!

Those Good Old IBM Mainframe Utility Programs

Most mainframe programmers are aware that IBM supplies many utility programs that are useful for system maintenance chores such as copying and deleting files, manipulating partitioned data sets, and the like.  

These utilities typically begin with an IEB, IEF, or IEH prefix.  One of the most common of these is IEFBR14, which is used to catalog a data set.  But few people are aware, however, that IBM also supplies many other utilities that can make the life of a programmer much easier.  Below is a select list of these:

IEBMAGIC        fixes any problem without having to use your brain; perfect for consultants and contract programmers

IEBIQUIT         automatically updates your resume, writes a letter of resignation, forwards it to your boss, and prints reams of paper to make it look like you actually did something when you worked here

IEBIBALL         compares any source file to the last one that actually worked displaying all changes and who made them; perfect tool for technical support personnel overwhelmed by programmers chanting the phrase "I didn't change anything"

IEBPANIC         if all else fails, run IEBPANIC; sometimes it fixes your problem and sometimes it doesn't, but it never tells you how it did it; companion program to IEBMAGIC;

IEBNOTME      alters all trace of your userid from system change logs, SMF, etc.; useful to eliminate finger-pointing; this should always be run before running IEBIQUIT

IEFINGER        when designing on-line systems sometimes intermediate screens are sent that serve no purpose other than to tie together a series of related transactions; these intermediate screens generally direct the user to "Press ENTER to Continue"; IEFINGER simulates the end user pressing the ENTER key thereby eliminating unnecessary screens

IEHAMMER      forces a square peg into a round hole; for example, if you try to compile a COBOL program using the FORTRAN compiler, attaching IEHAMMER to the compile will make it work

IEBPIG               finds all unused resources of any type and assigns them to any specified job

IEBHAHA         randomly changes source code in test libraries; it is often speculated that IEBHAHA is the cause of most program problems that IEBIBALL is used to correct

IEBEIEIO          run this utility when you have too many problems to handle for one person;  it corrects the old "with an abend here, and a meeting there, e-i-e-i-o" syndrome by causing a system problem so large (in someone else's application) that all direction is diverted away from you to them

So did I forget your favorite?  Drop a comment below to share it!

IBM Information on Demand 2013, Tuesday

The second day of the IBM IOD conference began like the first, with a general session attended by most of the folks at the event. The theme of today's general session was Big Data and Analytics in Action. And Jake Porway was back to host the festivities.

The general session kicked off talking about democratizing analytics, which requires putting the right tools in people's hands when and where they want to use them. And also the necessity of analytics becoming a part of everything we do.

These points were driven home by David Becker of the Pew Charitable Trust when he took the stage with IBM's Jeff Jonas Chief Scientist and IBM Fellow. Becker spoke about the data challenges and troubles with maintaining accurate voting rolls. He talked about more than 12 million outdated records across 7 US states. Other issues mentioned by Becker included deceased people still legitimately registered to vote, people registered in multiple states, and the biggest issue, 51 million citizens not even registered.

Then Jonas told the story of how Becker invited him to attend some Pew meetings because he had heard about Jonas' data analytics expertise. After sitting through the first meeting Jonas immediately recognized the problem as being all about context. Jonas offered up a solution to match voter records with DMV records instead of relying on manual modifications.

The system built upon this idea is named ERIC, short for the Electronic Registration Information Center. And Pew has been wowed by the results. ERIC has helped to identify over 5 million eligible voters in seven states. The system was able to find voters who had moved, not yet registered and those who had passed away.

"Data finds data," Jonas said. If you've heard him speak in the past, you've probably heard him say that before, too! He also promoted the G2 engine that he built and mentioned that it is now part of IBM SPSS Modeler.

This particular portion of the general session was the highlight for me. But during this session IBMers also talked about Project NEO (the next generation of data discovery in the cloud), IBM Concert (delivering insight and cognitive collaboration), and what Watson has been up to.

I followed up the general session by attending a pitch on Big Data and System z delivered by Stephen O'Grady of Redmonk and IBM's Dan Wardman. Stepehen started off  the session and he made a couple of statements that were music to my ears. First, "Data doesn't always have to be big to lead to better decisions." Yes! I've been saying this for the past couple of years.

And he also made the observation that since data is more readily available, businesses should be able to move toward evidence-based decision-making. And that is a good thing. Because if instead we are making gut decisions or using our intuition, the decisions simply cannot be as good as those based on facts. And he backed it up with this fact: organizations  using analytics are 2.2x more likely to outperform their industry peers.

O'Grady also offered up some Big Data statistics that are worth taking a look at --> here

And then Wardman followed up with IBM's System z information management initiatives and how they tie into big data analytics. He led off by stating that IBM's customers are most interested in transactional data instead of social data for their Big Data projects. Which led to him to posit that analytics and decision engines need to exist where the transactional data exists -- and that is on the mainframe!

Even though the traditional model moves data for analytics processing, IBM is working on analytics on data without moving it. And that can speed up Big Data projects for mainframe users.

But my coverage of Tuesday at IOD would not be complete without mentioning the great concert sponsored by Rocket Software. Fun. performed and they rocked the joint. It is not often that you get to see such a new, young and popular band at an industry conference. So kudos to IBM and Rocket for keeping things fresh and delivering high quality entertainment. The band performed all three of their big hits ("Carry On", "We Are Young", and "Some Nights", as well as a bevy of other great songs including a nifty cover of the Stones "You Can't Always Get What You Want."

All in all, a great day of education, networking, and entertainment. But what will Wednesday hold? Well, for one thing, my presentation on Understanding The Rolling 4 Hour Average and Tuning DB2 to Control Costs.

So be sure to stop by the blog again tomorrow for coverage of IOD Day Three!

A Forced Tour of Duty


Mainframe developers are well aware of the security, scalability, and reliability of mainframe computer systems and applications. Unfortunately, though, the bulk of new programmers and IT personnel are not mainframe literate. This should change. But maybe not for the reasons you are thinking.

Yes, I am a mainframe bigot. I readily admit that. In my humble opinion there is no finer platform for mission critical software development than the good ol’ mainframe. And that is why every new programmer should have to work a tour of duty on mainframe systems and applications after graduating from college.

Why would I recommend such a thing? Well, it is because of the robust system management processes and procedures which are in place and working extremely well within every mainframe shop in the world. This is simply not the case for Windows, Unix, and other platforms. By working on mainframe systems newbies will learn the correct IT discipline for managing mission critical software.

What do I mean by that? How about a couple of examples: It should not be an acceptable practice to just insert a CD and indiscriminately install software onto a production machine. Mainframe systems have well-documented and enforced change management procedures that need to be followed before any software is installed into a production environment.

Nor should it be acceptable to just flip the switch and reboot the server. Mainframe systems have safeguards against such practices. And mainframes rarely, if ever, need to be restarted because the system is hung or because of a software glitch. Or put in words PC dudes can understand: there is no mainframe “blue screen of death.” Indeed, months, sometimes years, can go by without having to power down and re-IPL the mainframe.

And don’t even think about trying to get around security protocols. In mainframe shops there is an entire group of people in the operations department responsible for protecting and securing mainframe systems, applications, and data. Security should not be the afterthought that it is in the Windows world.

Ever wonder why there are no mainframe viruses? A properly secured operating system and environment make such a beast extremely unlikely. And with much of the world’s most important and sensitive data residing on mainframes, don’t you think the hackers out there would just love to crack into those mainframes more frequently?

Project planning, configuration management, capacity planning, job scheduling and automation, storage management, database administration, operations management, and so on – all are managed and required in every mainframe site I’ve ever been involved with. When no mainframe is involved many of these things are afterthoughts, if they’re even thought of at all.

Growing up in a PC world is a big part of the problem. Although there may be many things to snark about with regard to personal computers, one of the biggest is that they were never designed to be used the way that mainframes are used. Yet we call a sufficiently “pumped-up” PC a server – and then try to treat it like we treat mainframes. Oh, we may turn it on its side and tape a piece of paper on it bearing a phrase like “Do Not Shut Off – This is the Production Server”… but that is a far cry from the glass house that we’ve built to nourish and feed the mainframe environment.

Now to be fair, strides are being made to improve the infrastructure and best practices for managing distributed systems. Some organizations have built an infrastructure around their distributed applications that rivals the mainframe glass house. But this is more the exception than the rule. With time, of course, the policies, practices, and procedures for managing distributed systems will improve to mainframe levels.

But the bottom line is that today’s distributed systems – that is, Linux, Unix, and Windows-based systems – typically do not deliver the stability, availability, security, or performance of mainframe systems. As such, a forced tour of duty supporting or developing applications for a mainframe would do every IT professional a whole world of good.

Mainframes: The Safe IT Career Choice

A recent Computerworld article (Bank of America touts mainframe work as a safe career) touts the mainframe as a safe haven for those considering a career in IT. This is an interesting article because the usual spiel you hear in industry trade rags is that the mainframe is dying and only a fool would work on such a platform. It is good to hear an alternate opinion on the matter in a journal as respected as Computerworld. (Of course, the fact that I agree with this opinion might have a little something to do with my cheer upon reading the article.)

One of the highlights of this particular article is the discussion of avialable mainframe jobs at sites such as Monster (764 jobs over 30 days) and Dice.com (1,200 ads over 30 days). These are significant numbers of jobs, especially in a down economy.

Another interesting tidbit from this piece is that "IBM says it's mainframe revenue has grown in eight of the last 13 quarters." This is impressive; consider the difficult servers market coupled with the impression that the platform is dying.

Speaking of the death of the mainframe, don't you believe it for a minute. People having been predicting the death of the mainframe since the advent of client/server in the late 1980s. That is more than 20 years! Think of all the things that have died in that timespan while the mainframe keeps on chugging away: IBM's PC business, Circuit City, Koogle peanut butter, public pay phones, Johnny Cash... the list is endless.

Some may counter that they recall reading about companies that were going to eliminate their mainframe. Well, yes, I'm sure you do remember those, I do, too. But do you recall reading many articles about companies that SUCCESSFULLY eliminated their mainframes? Many tried, few succeeded. Indeed, the re-Boot Hill web site provides examples of companies that tried to eliminate the mainframe but could not (hence, they had to re-boot). If you follow the link to the re-Boot Hill site click on the little tombstones to read the stories of failure.

So, the mainframe is a rock-solid platform, continues to grow, and is producing a significant number of job opportunities... what is not to like?

The Mainframe is Number One!

Congratulations to the mainframe, just cited at #1 in the InfoWorld Hardware Hall of Fame.

Okay, so maybe they are listing the hardware chronologically, but I refuse to acknowledge that. The IBM System/360 mainframe is listed first -- and that means number one, right?

Actually, the entire list is interesting and entertaining, so take a moment to click over and review the InfoWorld Hardware Hall of Fame, which is littered with titans from the past (DEC, Compaq) as well as current offerings.

Today's Modern Mainframe

IBM mainframes process two thirds of the world’s business information every day, and have
been doing so for decades, because of the many strengths provided by the mainframe, such
as high availability, good redundancy, high performance I/O capabilities, and much more.

But have you ever been challenged by an anti-mainframer by a statement like "Oh, aren't mainframes dead?" - or - "Why would anyone still use a mainframe?" Have you wanted a ready response that is easily digestible and not overly techie? Well, IBM has a new Redguide book titled The IBM Mainframe Today: System z Strengths and Values that might be of help.

This publication describes the business drivers, their impact on IT, and how the System z platform can be a major player for the business solution by providing flexibility, responsiveness to customers and market needs, as well as cost effectiveness. It also discusses the mainframe hardware, software, and environment, with an emphasis on the features and capabilities that make the System z mainframe a good choice for businesses.

Also, you may have noticed the new term: Redguide. Similar to an IBM Redbook, an IBM Redguide is not quite as technical as a Redbook, but more in-depth than a brochure or other pieces of "sales" collateral.

So, if you are a mainframer like me, you'll want to download and read The IBM Mainframe Today: System z Strengths and Value. After all, the price is right (free). And you'll want to keep an eye out for additional Redguides from IBM. Susan Visser recently blogged about the first 15 Redguides here.

The Mainframe Still Rocks!

Mainframe Executive, a new publication for CIOs and IT managers in enterprises with IBM mainframe systems, just published a list of 15 reasons to stay on, or move to, a mainframe. The list is a good one, covering reliability, availability, security, resource utilization, scalability, power consumption, staffing concerns, quality, and on and on.

Here is the list for those not inclined to click on the link:

1. Lowest outage costs from highest platform reliability, availability, and serviceability.
2. Lowest security breach risks/costs via most secure design, encryption, etc.
3. Highest resource use efficiency/utilization for mixed commercial workloads.
4. Widest platform scalability supports any workload size, mix, growth.
5. Consolidates many new workloads, extends traditional workload strengths.
6. Top data-serving capacity, performance, value—best Information on Demand host.
7. Highest QoS, best performance with fastest response times.
8. Best enterprise SOA platform; enables fullest reuse of mainframe application assets.
9. Much-improved cost model transformed mainframe economics.
10. Lowest power consumption, cooling, and data center floor space needs.
11. Lowest staffing and support costs for enterprise workloads.
12. Lowest total cost of ownership, total cost per user, and total cost per transaction.
13. Best customer investment protection for any enterprise platform.
14. Lowest business risk platform with best world class support.
15. Healthy, expanding mainframe ecosystem is supporting the platform.

If you are a mainframer this list won't come as any surprise to you... but it can be handy to keep it readily available for the next time someone attempts to convince you that mainframes are already obsolete, or should be.

In fact, maybe you can come up with additional reasons. After reading the list (http://www.mainframe-exec.com/articles/?p=12) feel free to submit comments here with any additional reasons you might come up with!


Also, for those who don't know, Mainframe Executive is published by Thomas Communications, the same folks who publish the excellent bi-monthly z/Journal.

History of the Mainframe

While researching some items on the web I ran across a couple of interesting mainframe-related sites that I'd like to share with you.

First up, on The History of Computing Project's site, is this entertaining and informative timeline of mainframe history. The timeline starts in 1939 with the creation of the Atanasoff-Berry Computer at Iowa State. If you are looking for historical events in the life of the mainframe, then this is a good place to start. It contains links to information about, and pictures of, some early mainframes including the ENIAC and the IBM 701.

Another interesting mainframe-related page is at Carnegie-Mellon's Software Engineering Institute site. I point it out not because I agree with the "stuff" written there, but because I find it amusing to see the word "LEGACY" stamped over every inch of the page. Wise up! The mainframe is not just legacy, folks!

And finally a nice little article with the proper perspective on mainframe architecture from IBM. I particularly liked the way this article ended:

As the image of the mainframe computer continues to evolve, you might ask: Is the mainframe computer a self-contained computing environment, or is it one part of the puzzle in distributed computing? The answer is that The New Mainframe is both...

Mainframe Career Still a Good Idea!

Just a quick post today to point you over to an article that ran in eWeek Magazine titled Big Iron Remains Career Option. Those of us who have worked with mainframes for decades know that mainframes still run the bulk of the mission-critical, high transaction workload for the biggest companies. And we know that you can make a good career out of mainframe development, administration, and management.

But it is good news that others are starting to hear this message.
