IMHO it very hard (close to impossible) to collect good information 
about sites without sligltly compromissing company information.
Anonymous contribution like "Big company in downtown Manhattan" can be 
easily duplicated by folks who do not know about each others contribution.
The only way to avoid duplicates is to provide something unique, like 
newest machine's serial number or IBM customer number.
Of course someone in the company may by not happy of that, despite the 
number is not really a secret nor important information.


Some partial information can be collected by harvesting user data from 
IBM-MAIN of SHARE or other communities, but it still partial.
Last, but not least: one still doesn't know whether the site is 200 or 
20 000 or 200 000 MIPS worth. Do they run the newest software versions 
in GDPS or it is 15 years old obsolete stuff with no PTFs and still "in 
the course of decomission".



BTW, some information about Poland:
3 banks (rather current and medium to big sites)
2-3 government sites (one big)
1 telco (fading)
the rest is under 1000 MIPS IMHO.

I also get information about historical VSE shop. So there were at least 
2 VSE shops, possibly one of the installations never went into production.


I also heard about Czech - 4 sites.

So, quick BOTEC (or rather, back of Lisp interpreter which is my desk
calculator of choice), assuming 7 bln total population and 7.111mln
for Serbia (from Wikipedia):

5]> (/ 70 (/ 7111024 4l0))

This gives about 4k z/OS and 1k VSE worldwide. Quite in agreement with
estimation given few posts earlier by Phil Smith, if I recall

There in Serbia (a small European market) we have:

1 VSE installations

Re: mainframe distribution

[Charles Mills]

IBM of course runs their business as they see fit. No amount of logic on 
IBM-MAIN is likely to change their minds. The people at IBM who make these 
decisions probably do not read IBM-MAIN. 

If we take Phil's point about some Wall Street analyst being able to say "look, 
the mainframe is dying" [or even "not growing very much"] it is one thing if he 
is working from best guesses from employment agencies, etc. It would be quite 
another thing if he had IBM's official numbers to cite.

Phil gave you numbers (that no one here has yet disagreed with) that should be 
good enough for you to make decisions about your business. What would you do 
differently if you knew there were exactly 4763 z/OS sites as opposed to Phil's 
"low thousands"? 

I'd like to know too. But there's a lot of things I would like that I'm not 
going to get.

It is funny they are trying to hide it. The information can be collected from

Why? It's proprietary information for IBM about their market. As a vendor for 
the last 35 years, I've wished for this information, but was never surprised 
that it wasn't available. Why would they want to release it? Sure, in boom 
times - at one point they said there were 20,000 VM installations. But that was 
a long time ago, and many of those were probably 9370s in a closet that were

Best guesses I've seen in recent years: low thousands for z/OS; fewer for z/VM

Why? It's proprietary information for IBM about their market. As a vendor for 
the last 35 years, I've wished for this information, but was never surprised 
that it wasn't available. Why would they want to release it? Sure, in boom

Heck, I don't even know how many installations are in my city - and that's only 
a couple hundred thousand people!  

The next question concerns "what's a site?"  Does a site need a mainframe?  Or 
can the physical equipment be across the country or somewhere else on another 
continent?  I know of at least 2 companies that have development staff local 
(one has hundreds of developers) but no hardware because their equipment is all 
at other locations.  We also have another large installation that will remain 
nameless that has lots of equipment but a skeleton staff maintaining it.  All 
operations, development, etc is elsewhere, they just have a data center here.  
Which of these qualifies as a site or an installation?

Those who know don't say; those who say don't know.

The question comes up here from time to time and the answer is always the same.

Brend,

​Ten twins and none of them if Asia? Please recommend the city of Stuttgart
have a twin city in Israel ;-) I can recommend some, if needed...

And, Ladies & Gentlemen, can we back to the main issue here: Mainframe

Bernd,
I know the installation and know people related to it.
Note: your 4381 was replaced with P/390 and after few years mainframe 
completely switched off.

For my knowledge they have never used VSE in production.
What they used was ODRA emulator under z/VM.
ODRA is licensed clone of ICL 1900 with GEORGE3 operating system. It 
was very popular in Poland.


BTW: at the time you also gave to MPK used tramway. (MPK is public 
transportation company).


completely off topic:

this is a video of the used tramway type "we" gave to MPK:

https://www.youtube.com/watch?v=hJsHcF14fBs=youtu.be

here in Arad, Romania (we did not only sell used tramways to Lodz,
but also to other countries, including Egypt).

Back to topic: on ODRA machine, there was a report generator language 
called TABU.
I wrote a TABU to COBOL translator in Pascal, which I still have here 
today.
I recently managed to compile this translator with my new Stanford 
Pascal compiler;

the translator runs on MVS and VM (and Windows, and Linux).
so (in theory) old TABU reports could still be executed on every COBOL 
system of today :-)
even on z/OS. The TABU language was not bad at all, much better than RPG 
IMO.


Kind regards

Bernd


BTW2: MPK just bought several used tramways, I think it was from 
Munich. New tramways are cery expensive (approx. 2 milion euro) and 
used one are ~30 times cheaper. Like a mainframe ;-)

Partnerstadt - Stuttgart has ten "twins":

Tschechien: Brno/Brünn seit 1989
Wales: Cardiff (seit 1955)
Ägypten: Kairo (seit 1979)
Polen: Lodz (seit 1988)
Tunesien: Menzel Bourguiba (seit 1971)

Russland: Samara (seit 1992)
Großbritanien: St. Helens (seit 1948)
USA: St. Louis (seit 1960)
Frankreich: Straßburg (seit 1962)

I'm not living in Stuttgart, in fact;
I'm living in Leinfelden-Echterdingen, which is about 12 to 15 km
from Stuttgart (south).

Leinfelden-Echterdingen has four "twins":

Manosque (southern France)
Poltawa (Ukraine)
York (USA, Pennsylvania, IIRC)
Voghera (Italy)

I've been in Manosque very often, I have friends there :-)
after all, it is a good region to spend the holidays

Endicott told me there was 6kbytes available for assist microcode ...  I
was to identify the highest used code paths in the vm370 kernel for
replication in microcode.
(standard 370 kernel instructions translated on about byte-for-byte
basis)

the low & mid-range 370 native (vertical) microcode emulated 370 on
about 10:1 basis ... so instructions moved from 370 to native code got
approx.  10:1 speedup.

old post with times I did of vm370 kernel for selecting 6k bytes of code
segments for dropping into "ECPS" microcode
http://www.garlic.com/~lynn/94.html#21

6kbyte cutoff accounted for 79.55% of kernel execution ... gets a 10:1
speedup.

At the same time there was VS1 handshaking that bypassed certain VS1
processes and left it to VM370 ... resulting in VS1 under VM370 ran
faster than stand alone on the bare machine.

Endicott then tried to get corporate approval to preinstall vm370 on
every 138&148 shipped from the factory (sort of like LPARs
today). However, this is in the period after Future System implosion and
mad rush to get 370 products back into the IBM product pipeline.  POK
kicked off 3033 & 3081 in parallel and convinced corporate to kill the
vm370 product, shutdown the vm370 development group and move all the
people to POK to work on MVS/XA (or otherwise MVS/XA wouldn't be able to
ship on schedule). Endicott managed to save the VM370 product mission
... but had to reconstitute a development group from scratch ...  but
wasn't able to convince corporate to allow vm370 to be preinstalled on
every 138&148.

Note since DOS/VS and VS/1 were single virtual address space (something
like original VS2, SVS) ... E-architecture dropped the single virtual
address table into microcode ... and there were new hardware
instructions to add the virtual->real address page mapping. VM370
always ran in 370 mode supporting multiple address spaces.

4341 caused lots of problems for POK ... it performed better than 3031
(erzats 158) and small cluster of 4341s outperformed 3033, cost much
less than 3033, had smaller footprint and used much less environmentals.

In 1979, I got con'ed into doing 4341 benchmarks for LLNL that was
looking at getting 70 4341s for compute farm ... sort of the leading
edge of the coming cluster supercomputing (and cloud megadatacenter)
tsunami.

It was so threatening to highend mainframes, at one point, head of POK
got allocation of critical 4341 manufacturing component cut in half.

The price, environmentals & footprint for 4300s & FBA disks had dropped
so far, that corporations started ordering large hundreds at a time for
placing out in departmental areas (inside IBM it resulted in conference
rooms becoming scarce commodity) ... sort of the leading edge of the
coming distributed computing tsunami.

Boeblingen lab had done 370 115&125 ... which was a nine position memory
bus for up to nine microprocessers ... for the 115, all microprocessors
(controllers, 370 "cpu", etc) were the same but with different microcode
loads. The 125 was identical to 115, but the microprocessor for the 370
"cpu" was 50% faster (than the other microprocessors). This
design/implementation was so threatening to other 370 models, the got
corporate to discipline Boeblingen.

At the same time that Endicott con'ed me into working on ECPS microcode
assist (for 138/148), I got con'ed into doing 125 design/implementation
which would have up to five of the faster CPU processors all in the same
machine (with four positions left for controllers). In same ways it was
as threatening to Endicott 148 as 4341 clusters was threatening to 3033.
In the escalation meetings by Endicott to kill five processor 125, I was
expected to do the technical arguments for both sides (pro/con 148+ECPS
and pro/con for 5-way 125)

There was one, when we helped to replace the ODRA machines at MPK Lodz (similar 
to British ICL machine,
George-3 operating system, IIRC)
with a VM 4381-12 running VM (DB2, Pascal) and VSE (CICS, DB2, COBOL) in the 
beginning of th 1990s. I was there two times,
1992 and 1994, to help with the installation and customization of the machine.

Yes, indeed. VSE was IMO maintained to a large part in the Boeblingen lab, 
which is 10 km from where I live.

We had it at the Stuttgart public transportation company (SSB), which was the 
company which helped MPK (see above).
Stuttgart and Lodz are partner towns (jumelage in French, don't know the 
English expression).

Often the expressions "twin towns" or "twin cities" are used, which is
exactly translatable with the French term. But the word is a little
awkward when there are multiple "twinnings". Wikipedia seems to think
that the common term is "sister cities", which makes sense in the case
of multiples. What term is used in German?

I'm pretty sure IBM is not wiling to share this information. Maybe 
some companies like Gartner have some view, but they would want money 
for that information.


Small piece of info:
Poland - 0,00 VSE installations. IMHO historically it was always 0.


There was one, when we helped to replace
the ODRA machines at MPK Lodz (similar to British ICL machine,
George-3 operating system, IIRC)
with a VM 4381-12 running VM (DB2, Pascal) and VSE (CICS, DB2, COBOL)
in the beginning of th 1990s. I was there two times,
1992 and 1994, to help with the installation and customization
of the machine.



Also, people say VSE is popular in UK and Germany.




Yes, indeed. VSE was IMO maintained to a large part
in the Boeblingen lab, which is 10 km from where I live.

We had it at the Stuttgart public transportation company (SSB),
which was the company which helped MPK (see above).
Stuttgart and Lodz are partner towns (jumelage in French,
don't know the English expression).

Kind regards

Bernd

Re: mainframe distribution

[R.S.]

z/OS sites - approx. 50, but majority is small. Only 5 sites above 1000 
MIPS.

(I know all of them, worked somehow for significant part of them)

AS/400 aka System i -  I have no idea. I know few installations, but I 
don't know what is the part of whole picture.
People say, in early 2000's the largest AS/400 machine in a world was 
located in Poland, Katowice (and it was constantly overloaded).


BTW: People asy the total number of mainframe sites across the world is 
approx. 10 000.
Of course it disputable whether there is sense in counting 200 MIPS site 
and +200k MIPS site simply as two pieces.
Not to mention some sites are up to date and some are very very old, 
obsoleted in terms of HW, SW, application.

How about z/os sites? As/400 sites? I am sure 3rd party vendors has the
information, at least partially.
Un Israel there are about 10 VSE sites and 15 z/os. AS/400 is much more
popular.

It could be easier if you could try obtaining the formula of coca-cola or KFC 
... These things are guarded by jealous insiders...

I am very pretty sure you will not get a number (for z/OS) at all. Perhaps some 
outdated figures yes, but nothing current.

Perhaps you can get some number of datacentres, but how many z/OS LPARs or 
SysPlexes, etc. that is pretty hard to find out.

As Radoslaw said, you may have to pay to get info or you may need to sign a NDA 
if you want it.

Or better - become an Big Blue Top-Brass guy and then tell us for free... ;-)

Oh, BTW, you are not the first asking this and similar questions on IBM-MAIN. I 
remember that I searched my  off years ago trying to find a good 
estimate...
