With some help from the SZE community, I can now log my service uptime and latency in #Db2 using #Golang !

I've got a service called CompInvZ which links into my Db2Z host to find services, then it periodically tries to connect and records the result back to DB2

A friend of mine took it a step further and is using #ISPF to interact with Db2 via #REXX

That means #CICS is next on the list, thanks #Walmart !

Что если бы в Аэрофлоте были ИБМ МФ и z/OS

В свете ситуации, случившейся с крупнейшим авиаперевозчиком России, приведшей к огромным потерям десятков тысяч пассажиров в первую очередь и самого перевозчика во вторую, уместно порассуждать о "как это было на самом деле", и "что если бы". Начну с "как это было на самом деле".

Как измеряется работа выполненная в z/OS и что из этого следует

Если спросить администратора любой системы на х86 сервере в чем их система и как измеряет выполненную работу, то в ответ услышишь "А зачем это надо? Выполняется и хорошо. Чего еще?". Может я ошибаюсь, поправьте в комментариях. Здесь я хочу рассказать о измерении выполненой работы в z/OS, зачем это делается и какие из этого могут быть финансовые последствия (нет не штрафы и пени, а скорее наоборот).

Чем различаются ОС IBM мейнфрейм и ОС х86

Это статья в формате вольного пересказа более чем сорокалетнего периода работы с разными ОС, главным образом с ОС мейнфрейм, и размышлениями об их сходстве и различиях (в большей степени о различиях, конечно). Многие популярные ОС выполняются на серверах (речь в статье пойдет исключительно про серверные ОС) х86 (Intel, AMD). Это Линукс разных мастей и названий, и Windows. В силу уклона российского образования в сторону инфраструктур на основе х86 у многих айтишников есть твердое убеждение, что то, как написаны известные ОС, это единственный вариант, как ОС и могут быть написаны. Попытки писать свою, российскую, ОС сводятся к написанию очередного Линукса. Но есть и другие, современные ОС, выполняющиеся не на х86 платформе. Это одна из ОС IBM мейнфрейм (МФ), называемая z/OS. IBM МФ — тоже весьма современная техническая платформа. В апреле этого года IBM анонсировали новое поколение z17, т. е. семнадцатое поколение, начавшее свою историю в далеком 1964 году.

Mind blown. You can run IBM #zos on a PC with a personal edition license.

https://www.ibm.com/docs/en/zdt/14.2.x?topic=personal-edition

And it has IBM #COBOL inside it. I don't understand why this was so hard for me to find. Looks like I need a new machine (linux host, 1tb drive space and then enough oomph to run a VM)

@Sheep_Overboard I am going to have to object. I work for mainframes, and our host code is 98% COBOL, it's very fast and reliable. A lot faster than Java, C, C++ etc. According to a 2022 study there are 800 billion lines of COBOL in use on a regular basis. I admit, I write z/OS assembler, and am a bit biased, but COBOL is still incredibly popular.

"According to surveys by Micro Focus (2022), around 800 billion lines of COBOL code are used in production every day."

To any #mainframe #zos peeps out there… do you have any PARMLIB monitoring at your shop?

I’m bothered by this one statement from Long Pela’s February 2023 Quarterly:

#IBM haven't produced a single utility to validate z/OS PARMLIB settings.

My possibly ill-informed opinion on the mainframe developer market

#zOS work has so many barriers
- Can't run it locally. Only 1 training program at IBM for terminal access. (wrong! prersonal edition exists)
- The only mainframe code you can run locally is MVS from the early 1980s
- GNUCobol is probably not like modern IBM Cobol
- Microfocus appears to be in financial crisis and you can't even get a trial license compiler, let alone a personal license compiler

Can you connect output from your COBOL copybooks to @ApacheKafka?

You can now 🤯

"IBM® Open Enterprise SDK for Apache Kafka® is a no-charge SDK that allows COBOL or C/C++ code running on z/OS® to natively communicate with a Kafka broker and to transform between COBOL copybooks and JSON events." #ApacheKafka

See, I told you lots of familiar distributed tech is landing in the #mainframe world!

As a muscle memory check from things 33 years ago, I wanted to know how much the #ibm #mainframe under #zOS has changed from /370 back then.

Yes, we are now at #JES3 - and the new things for me were PDSEs and USS - feels weird calling #OMVS and having a #Linux environment #shell on the mainframe. Ah yes, we did not have #FICON either back then to define CHPIDs but the 3380 and 3390 were actually huge boxes connected via #bus and #tag cables.

#IBM #zOS is like $2k/mo for their smallest VM, #Ubuntu on the same #s390x hardware ( 1 vCPU, 4GB RAM) is $74/mo 😂 I'd probably splurge for #RedHat before Ubuntu, but I want to learn z/OS better 😭

"ok, can you create a branch? I'm gonna need to port this to Visual Basic first"

😅​ Seriously, I do git it. There are many nations out there: #Windows, #Linux, #Mac, #zos and languages like #BASIC and #APL.

"I get that "you fix it" attitude rarely... "

I'm glad to hear it. But even asking me to branch is beyond my pay grade, and of most of the user base's comprehension. Neither the spouse or grannie are going to get this.

I was working with open source #Zowe stuff for three years, but then the Open #Mainframe Project fielded a mandatory conformance project I had to contribute to. The .md instructions were so bad, I had to rewrite them (RS is an #Author). In any case, they required me to do a #GitHub "pull request" to check-in my contribution (a json file) and for the .md file.

/RS.exe crashed at that point./

I pawned the project off on one of my Linuxy coworkers. Open source #programming is likely something people get really used to, but if you are a mainframer, Javascript and C programmer, or a Windows programmer, that's simply is Greek and is just one more thing to learn when I have no time because I have a dozen things to get done first.

Shoot. Ranted again. #ADHD Please forgive me!

IBMers,

I have a couple of questions as my curiosity and interests have been leaning kinda towards mainframes.

1. How are mainframes utilized in 2024?
2. How does the mainframe business work? I am assuming large contracts for hosted services?
3. Is there enough growth career-wise to merit a segue from another tech related position into mainframe support?
4. Do I have to learn COBOL?
5. Are there any other companies providing similar hosted services at scale?
6. Are there any resources available to learn up on Z/OS and any other services IBM provides? (For free?)
7. Can we be friends?

Any info is appreciated.
Hats off to all the humans supporting the BIG COMPUTERS.

"Better to be thought a fool," he said. Austin Osman Spare never attempted to disabuse his wealthier, more socially-advantaged contemporaries, such as Dion Fortune and Aleister Crowley, of the impression that he thought it was the pie & eel gland that was the 'Third Eye' of the mystics.
