I’ve explained zAAPs and zIIPs as “games IBM plays to keep mainframes somewhat

We’ve licensed a package manager (Artifactory in our case, but I imagine there

This is mostly so we can manage local packages that we’ve developed just for

Why Python? I know it's the latest hot language, but what advantages does it

The context here was using Python in place of REXX. It’s a scripting language,

linking or such.


I have looked into it a few times, but get as far as "significant indentation" 
and "no variable declarations" and decide it's not something I want to use. Is 
it a sign of weakness to ask the compiler to help me avoid bugs?

You get used to the “significant indentation” thing pretty quickly. It really 
makes sense: you should be indenting blocks anyway to make them easy to read, 
so why clutter things up with braces or keywords?

Most scripting languages (including REXX) don’t require declaring variables. 
Since there’s no separate compile step you get the errors when they happen in 
any case, so declaring variables doesn’t buy you much.

Python allows me to mix object-oriented and functional programming, it doesn’t 
require a lot of “ceremony”, and it makes it easy to write short but readable 
programs.

Apple switched to zsh because newer versions of bash are covered by the GPLv3

that IBM has similar motivation.

If you’re still seeing bash on a Mac that probably means you started using it

to do something (probably in Terminal) to get it to switch for me. (It used to

while getting off the mainframe is still a long term goal, they aren’t setting

I’d say that code pages aren’t particularly relevant to JCL processing. JCL

interpretation across many if not most of the code pages in the “EBCDIC” 
family. As you noted, all of them have the same interpretation in three 
commonly used code pages.

Most possible byte values aren’t acceptable to JCL, only the ones in the 
“syntactic character set”. (In some places you can “sneak” other values in 
between single quotes, of course, but JCL treats those things as opaque 
sequences of bytes.) Talking about code pages for JCL just confuses things, so 
I think the manual authors were wise to avoid mentioning cp037 or any other 
code page.

How do people handle /SYSTEM/etc and /SYSTEM/var when upgrading z/OS? In the

the same during any upgrades unless we deliberately changed something. For our 
last upgrade (this past weekend) our management outsourced the upgrade to a 3rd 
party service provider, and the sysprog doing it configured completely new 
filesystems for these that were the generic IBM-provided versions, without any 
of our customizations. He claims this is a best practice. What say ye?

The message is issued only as frequently as the check is configured by you to

Stopping HZSPROC is surely the wrong reaction to this specific situation. If 
you simply don't want this check to run because you're aware of the problem 
then deactivate the check or change its parameters.

Unfortunately, the person who actually knew anything about Health Checker here 
was forced to retire early, and no one else has had time to learn about it. 
We’ve had problems keeping a full staff. As I mentioned, I’ve been semi-retired 
(working less than half time) since January. Our management contracted a 
third-party support company to supposedly fill in our gaps, but to say that’s 
been a disappointment would be an understatement. (They were supposed to have 
upgraded us to z/OS 2.5 by now.) Their excuse seems to be that they have 
trouble keeping their staffing complete too.

Sorry to kind of rant about this, but it’s been frustrating. I’m sure Health 
Checker is great if you know what you’re doing, but we don’t and can’t seem to 
get the resources to get there easily.

Problems caused by Health Checker?

[Pew, Curtis G]

We’ve occasionally had problems with our production z/OS LPAR that seem to be 
caused by HZSPROC, and I was wondering if anyone else has seen anything like 
this.

One problem we’ve seen is that sometimes when HZSPROC starts during an IPL, it 
for some reason seems to try to access a migrated dataset (we use FDRABR for 
dataset migration) and since DFRMM hasn’t started yet the recall fails. (We 
don’t know what dataset it is trying to access; none of the datasets explicitly 
in the PROC ever migrate.) Everything seems to freeze until we reply “CANCEL” 
to the EDG4012D message.

This is annoying enough, but last Thursday one of my coworkers stopped HZSPROC 
because it was repeatedly issuing the message that ECSA usage was high. (We’d 
already scheduled an emergency IPL for Sunday to fix that.) Then Friday another 
coworker tried to restart HZSPROC to see if he could figure out the migration 
issue, and our system stopped working well. It looked like batch jobs were 
stuck in allocation or deallocation from what was described to me. (I’m 
semi-retired and don’t work on Fridays.) They decided to go ahead with the 
emergency IPL then and there, but without HZSPROC starting. That IPL went fine 
and we haven't seen any issues since then, but we’re afraid to try to start 
HZSPROC.

Has anyone had issues like this with Health Checker? Any suggestions for how to 
resolve this?

Thanks.

Have you considered converting your SMF setup to use logstreams instead if

When you start up a syslog daemon on z/OS, you must pass it either ‘-c’ or ‘-n’ 
as an argument. A daemon with ‘-c’ only accepts local syslog calls, while one 
with ‘-n’ only accepts remote calls. If you want to do both, you need to start 
two daemons with the two different arguments. The default JCL IBM supplies has 
‘-c’, so if you’re using that it won’t accept remote UDP connections.

Hope this helps.

That reminds me of a story my father told me. In the late 1960s, while employed 
by IBM, he was working on a telecommunications program. IBM had arranged for 
some test time late at night on a customer’s S/360, and the whole team was 
flown to the customer site for the test. However, when they tried to IPL their 
test system it failed because the unit address for the tape drive had been 
coded incorrectly. While his boss was ranting at whoever he held responsible 
about how much money they were wasting, my father quietly walked over to the 
console, found where the address was stored in memory, fixed it, and restarted 
the load. He waited for the boss to run down and then said, “I fixed it; it’s 
working now.”

Lots of IBM manuals still say MVS when talking about that component. I find it 
convenient, for example, to distinguish “MVS datasets” from “Unix files”. 
They’re both part of z/OS.

I’ve explained it to people as being like Darwin and macOS. Every macOS (since 
macOS X) is built on Darwin, Apple’s fork of FreeBSD, so you can’t get macOS 
without getting Darwin too. And since, unlike MVS, Darwin is open source you 
*could* run it without all of macOS, no one ever does.

This was perhaps clearer with OS/390, which IBM explicitly positioned as an 
integrated package of components you previously could get separately.

Well, if the question is “can you use Rocket’s port of git for z/OS with GitHub 
Enterprise?” then the answer is definitely yes. The University of Texas has 
both, and I use them together all the time.

I’m not sure what you’re asking with “GitHub Enterprise making a copy/mirror of 
the original repos on z?” That’s not really the way git works: it’s a 
distributed version control system, so you always have a local copy of the 
repository.

If I’m starting a new project, I usually create a repository on GitHub 
Enterprise, and then clone it on whichever z/OS LPAR I’m working on, as well as 
on my laptop. Then I use `git push` and `git pull` to keep them in sync.

One might argue that Python and Ruby (at least, I’m not familiar enough with

Python is available, and so is node.js, which is server-side JavaScript.

I believe that the console address space handles modify commands by sticking 
everything after the comma into a buffer and passing that to the referenced 
job. Then it’s up to the receiving code to decide how to parse it.

The ugliness may be more desirable than loading and deleting the called module

I have a vague recollection that in the early 1990s IBM provided a TCP/IP stack 
on MVS that was ported from VM, but sometime in the OS/390 era it was replaced 
by a new Unix-based implementation.

In HCD there are two parts to the “OSA Advanced Facilities” configuration, a 
server configuration and a sessions configuration. In the server configuration 
you specify an IP address, subnet prefix, and TCP port number for one or both 
of the physical ports. Then you may specify a single gateway address, which 
should be on the same subnet as one of the physical ports. The port whose 
address is not on the same subnet as the gateway will be inaccessible to any 
host that is not on the same subnet as that host. For example, one of the cards 
on the University’s z14 ZR1 has port 0 IPv4 address 10.157.166.44/27 and port 1 
IPv4 address 192.168.2.13/24 and IPv4 gateway address 10.157.166.33. When I’m 
on the University’s VPN (or when I was on campus back when we still did that) I 
can connect to port 0. However, only hosts with an IP address of 192.168.2.xxx 
(which are confined to the data center) can connect to port 1.

Then there is the session configuration. Each session is assigned a CSS id and 
an MFID (which selects an LPAR) and a unit number; it is identified by an LU 
name. You can connect to a session from either port, but as part of the session 
definition you can filter by client IP address.

So if what you want to do is isolate consoles for different LPARs, you need to 
be looking at the session definitions, not the port definitions. Although, of 
course, all clients will need to be able to access one or the other of the 
ports.

You can do that, but only one of the ports will be accessible from other 
subnets. The OSA-ICC definition only supports a single gateway. So, for 
example, if you define the gateway with an address in the 192.168.10.100/16 
subnet, any client that can route through that gateway, as well as other hosts 
in that subnet, will be able to access the console through port 0, but only 
hosts with addresses in the 10.152.200.100/16 subnet will be able to access the 
console through port 1.

I hope my explanation makes sense.

The studies cited took place in the 1980s and probably with people with little 
exposure to personal computers, or at least computers with graphical 
interfaces. Muscle memory is definitely a thing.

But the real point is that you can’t trust how long it seems to take. “Time 
flies when you’re having fun,” and it drags when you’re bored. Unless you’ve 
performed a real measurement, you don’t really know which is faster.

The context was comparing command-key sequences to clicking buttons or 
selecting menu items. Remembering the command-key sequence takes as long as 
moving the mouse, but the brain doesn’t perceive the time passing while 
remembering, while it does perceive the time passing while manipulating the 
mouse.

The linked article does include an exception:

“And, in fact, I find myself on the opposite side in at least one instance, 
namely editing. By using Command X, C, and V, the user can select with one hand 
and act with the other. Two-handed input. Two-handed input can result in solid 
productivity gains (Buxton 1986).”

The point is subjective time is heavily dependent on cognitive engagement:

“People new to the mouse find the process of acquiring it every time they want 
to do anything other than type to be incredibly time-wasting. And therein lies 
the very advantage of the mouse: it is boring to find it because the two-second 
search does not require high-level cognitive engagement.

“It takes two seconds to decide upon which special-function key to press. 
Deciding among abstract symbols is a high-level cognitive function. Not only is 
this decision not boring, the user actually experiences amnesia! Real amnesia! 
The time-slice spent making the decision simply ceases to exist.

“While the keyboard users in this case feels as though they have gained two 
seconds over the mouse users, the opposite is really the case. Because while 
the keyboard users have been engaged in a process so fascinating that they have 
experienced amnesia, the mouse users have been so disengaged that they have 
been able to continue thinking about the task they are trying to accomplish. 
They have not had to set their task aside to think about or remember abstract 
symbols.

“Hence, users achieve a significant productivity increase with the mouse in 
spite of their subjective experience.”

“We’ve done a cool $50 million of R & D on the Apple Human Interface. We 
discovered, among other things, two pertinent facts:

• Test subjects consistently report that keyboarding is faster than 
mousing.
• The stopwatch consistently proves mousing is faster than keyboarding.

“This contradiction between user-experience and reality apparently forms the

Why not? In contrast to paper manuals, web applications can have hyperlinks 
that provide for multiple paths through a task.

I don’t want to go on a rant, but I see far too many web applications with 
unnecessarily modal interfaces. Too often we just recode a command-line 
application or paper process without redesigning to the strengths of the richer

Let me expand a bit. We’ve had the Universal Agent piece for Unix, Windows, and 
z/OS for nearly 20 years. We got the Automation Center piece 5 or 6 years ago. 
From our perspective the product is solid, and Stonebranch is very responsive 
to support incidents and feature requests. Although a lot of the focus is on 
automating non-mainframe platforms, they have several engineers with a strong 
mainframe background.

That shows the storage group but not the dataclass.

I’m pretty sure DATACLAS, for both disk and tape, is used during ACS routines 
and allocation in general, but isn’t ever stored anywhere. It’s a place for the 
system to get information when allocating the dataset, but then it’s discarded.

When I started out I wanted a larger boundary (256), but when that didn’t work 
I tried reducing the boundary and increasing SECTALGN to see if it would help.

Also, if I understand how ORG works correctly, the semantics of using ‘*’ for 
the expression are different from omitting an expression. The first sets the 
location counter to its current value (before increasing it to the boundary) 
while the second sets it to the highest available location in the current 
CSECT. So if I need to make sure I’m at the end of the current control section 
(this code is in a macro, so I won’t in general know that the location counter 
is already there) I’ll need two ORG statements:

ORG ,
ORG *,256

That seems less than optimal.

ASMA500W using _boundary_ on ORG statement

I’m trying to use the _boundary_ parameter on an assembler ORG statement, and I 
keep getting ASMA500W errors. I’ve specified GOFF and SECTALGN(4096):

However, when I try to set a boundary on an ORG statement:

The last time I checked, 8 did not exceed 4096. Anyone have any suggestions

We’re still at 2.3, and I tried it and it worked. I don’t apply PTFs for z/OS

identical regardless of whether the calculations are done in SI, imperial, or 
customary units. Nearly all manufacturers quote their engine performance in 
seconds, and the unit is also useful for specifying aircraft engine 
performance.[6]

“The use of metres per second to specify effective exhaust velocity is also 
reasonably common. The unit is intuitive when describing rocket engines, 
although the effective exhaust speed of the engines may be significantly 
different from the actual exhaust speed, especially in gas-generator cycle 
engines. For airbreathing jet engines, the effective exhaust velocity is not 
physically meaningful, although it can be used for comparison purposes.[7]

“Meters per second are numerically equivalent to Newton-seconds per kg 
(N·s/kg), and SI measurements of specific impulse can be written in terms of 
either units interchangeably.[citation needed]”

As long as you stay near the earth’s surface, you can treat mass and weight as 
equivalent. But kilograms measure mass, not weight. If I go into orbit around 
the earth, my weight has gone to zero, but my mass hasn’t changed.

If 30s are hot, what do you call 40s? We hit 106°F last week, which is just 
above 41°C.

Well, if the posted limit is 55 mph, 62.5 mph seems about the right speed to 
go. 😉

But duck-duck-go tells me 100 knots is 115.078 mph, or 185.2001 km/h.

For science and engineering I totally agree: you should never use anything but 
SI units. They have precise definitions, and being decimal-based make 
calculations easier. Not to mention being used world-wide.

For everyday life, though, I think American/Imperial units (and any other 
traditional systems that may survive elsewhere) have their advantages. They 
evolved because people found them useful. For example, when I’m cooking I could 
say 250 milliliters or one cup (they’re close enough for the precision I need) 
but one cup is simpler. Or if my pedometer says I’ve walked 2000 steps I know 
I’ve gone about a mile. (“Mile” comes from “mille passuum” = “a thousand of 
steps”; my pedometer counts left and right as separate steps but for the Romans 
you had to move both before they counted it.)

Yep. For precision definitions, always use SI.

I think it’s cool that SI units are now defined by specifying exact values for 
physical constants.

This supports my point about the convenience of traditional units. Fahrenheit 
is more granular than Celsius, so you can be a bit more precise without having 
to go to decimals.

HCD graphics report format

I was doing some updates in HCD and noticed the graphics report function, so I 
tried it. The output looks like input to groff or some such. Does anyone know

google-fu hasn’t worked so far.

Right. But in our case what COULD run on zIIP was going to depend on whether or 
not we could rewrite our code.

1. Determining what our zIIP and non-zIIP capacity needs would be. In other 
words, since we didn’t have zIIPs before we weren’t sure how much of our 
workload would actually run on the zIIPs.

2. The biggest thing was that we are an Adabas/Natural shop, so we were hoping 
to run both those products zIIP-enabled. However, we have a home-grown security 
system that’s implemented by several thousand lines of assembler code that runs 
as a part of the Natural session, and this code was doing things like issuing 
SVCs and examining the current TCB, and those things don’t work when you’re 
running zIIP-enabled. So the challenge was if we could rewrite all that code to 
work on zIIPs. (And see “how much of our workload could run zIIP-enabled” 
above.)

We were able to get the code rewritten, and we’ve been very happily running 
Adabas and Natural zIIP-enabled ever since.

I just gave a presentation to our user community about the z10 BC → z14 ZR1 
upgrade we did last August. One of the most challenging things about this 
upgrade was our z14 has zIIPs, which we didn’t have before. But try explaining 
zIIPs and CP capacity levels, or processor characterization in general! Those 
are totally irrational, except in the context of how mainframe software is 
priced.

Several years ago I moved all our DASD to “3390-54” with 65,520 cylinders. This 
was on a Hitachi VSP. Just this February we migrated to an IBM DS8882F. I had 
some space left over so I created some EAVs, but I consider them while I work 
out how best to utilize them.

On the Hitachi I used the GUI to define the virtual volumes and LCUs, but on 
the IBM disk I used DSCLI.

You quote just the part you’re responding to, and then give your response. That 
way it’s unambiguous just what your response refers to. There’s no need to try

The distinction is that sizeof is calculated by the compiler during

That’s an important point. Dates are often used in calculations. SSNs mostly 
just used as keys and stored. For Y2K we had to fix code that was doing date 
arithmetic, but you wouldn’t have that if they expanded SSNs.

I didn’t think this article was all that bad. The biggest error was in a quote 
from a politician, which I understood to be giving an example of some of the 
stupid stuff people (mostly politicians) are saying. I thought it could be 
clearer that by the “newest version” from 2014 they meant “the most recent ANSI

this wasn’t that bad.
