If you’re in IT at a Big Important Company, much of your most important application logic probably resides on an IBM mainframe. And you’re not re-platforming it any time soon.
You therefore face three serious challenges:
Updating your mainframe application logic in response to your constantly changing business needs as aggressively as you […]
On July 8, a Compuware software architect named Gary Michalek walked into my office and described a brilliant product idea he’d come up with over the fourth of July weekend.
On October 1, we’ll release the initial version of that product. That’s just 84 days from idea to innovation.
And, yes, we’re a […]
Millennials have to save the world. They are, after all, inheriting a world in crisis. Climate change, economic disparity, global political upheaval—these are all problems left to them by preceding generations to solve.
One of the biggest crises facing Millennials, however, gets very little media attention. That crisis is the future […]
With the release of COBOL 5.1, IBM has finally delivered a compiler that fully exploits the advantages of System z architecture. As a result, IT organizations recompiling their code in COBOL 5.1 can run their existing mainframe applications with 10-20% less CPU utilization. That can save companies millions.
These aren’t just […]
I came across an interesting article last week entitled “Tassie retailer rejects cloud for mainframe.” It described how an Australian supermarket chain was bucking the “cloud computing” trend by upgrading to the latest Unisys mainframe technology to run its core business, including a 20+ year-old application suite.
The article highlights the […]

As we’ve blogged about many times before, the IT industry is facing a mainframe skills shortage in the not-too-distant future. And for some companies, the future is now. According to a recent survey by Computerworld, 22 percent of COBOL programmers are aged 55 and older. And, some 50 percent are […]
Computerworld recently ran an in-depth article titled “Brain Drain: Where Cobol systems go from here”
This tends to be a particularly charged discussion since these days there is simultaneously a Cobol skills shortage and Cobol programmers out of work. I was happy the author extended the discussion into two other areas: […]
There are many well known limits for mainframe software. In this post, we’ll start by taking a look at the z/OS system and related software, and discuss some of these limits and how they have affected the workplace throughout the years.
For IBM S/360, the most common and popular limit is […]
