We know what COBOL stands for

How many times have you come away from a conference or a presentation and thought wow, that was really useful? Perhaps one small nugget of information from the speaker has opened a door for further development of work at your site. And most technical presentations are full of gems of information – both for the novice user and those more technically experienced.

I’ve been putting together a list of CICS tools and I thought I’d share some of the information I’d found.

Now I’m not here to tell you what software to buy and what to ignore, but if you haven’t had a look at IBM’s Transactional Analysis Workbench software yet, I think you should. It’s one of those pieces of software that kind of joins up the dots and allows you to see the bigger picture when you thought there was a performance problem. It can help identify performance issues in one subsystem – CICS, IMS, DB2, MQ, or even z/OS itself – when the symptoms of the problem are appearing in a completely different subsystem.

It’s so easy to forget, or just take it as read, that mainframes have been able to successfully run with five nines availability for well over a decade. What that means is achieving 99.999 percent of scheduled uptime. In other words, it means that unscheduled downtime is less than five and half minutes in a year! Now that kind of amazing performance is something that boxes running other operating systems can only dream of. Some are working towards that level of availability, but others (you know who I’m thinking of here) aren’t even close.

I’m a mainframe guy. Cut my teeth writing COBOL, PL/I and FORTRAN on the IBM System/370. CICS is my friend. Was playing with virtual machines long, long before there was anything called “DOS” or Windows” or “Linux.” My office closet is filled with punch cards and old nine-track tapes, all probably unreadable today. One of the happiest days of my professional life was trading in an old TeleVideo 925 monochrome terminal for a brand-new 3279 color display.

Micro Focus, the provider of enterprise application modernization, testing and management solutions, has released a new ‘managed code’ version of the company’s mainframe migration and application modernization solution for the Microsoft Application Platform including Azure. This new release is aimed at helping large organizations mitigate risk and dramatically reduce costs by migrating their Cobol, CICS (Customer Information and Control System) and DB2 applications to the Microsoft Application Platform.

Flashback to the 1980s, when IBM is still shipping source code for big-iron internals, says this mainframe pilot fish.
“IBM discontinued supporting BTAM under CICS, but we had a major customer who communicated via CICS BTAM,” fish says.
Translation: The big customer uses the CICS transaction-processing system, and connects to it over telecommunication lines using the very old BTAM protocol — and IBM has just stopped supporting that approach. READ MORE

The scuttlebutt on the job market related to mainframe now comes across to me as this:
Ten years ago, if you have worked mainly as a mainframe programmer, particularly in the old-fashioned world of nightly cycles, JCL, on-call support, COBOL, CICS, S0C7’s, AbendAid, etc (don’t we remember this), it was more prudent to grow your background in the mainframe area where you had focused expertise, than to move into client-server, where it’s hard to pick things up in non-linear learning curve mode. Why?
