Re: Python SDK for z/OS 3.11 is zIIP eligible

[Martin Packer]

A couple of points to make:

1) The “up to 70%” makes 70% a target, not a guarantee.

2) Only certain python libraries are zIIP eligible. Think about the case where 
someone wraps their COBOL program in just enough C to make a python module. 
Then – if we didn’t have this specific list – that COBOL program would’ve been 
zIIP eligible. Not something IBM intends.

The above are observations as a field guy who sometimes lectures on zIIP and 
who has talked to the relevant people about the “up to 70%” point.

Cheers, Martin

The doc appears to not disallow the offload based on machine model.  I thought 
it odd to cap the offload to 70% though

• z16
• z15™
• z14®/z14 model ZR1
• z13®/z13s®
• zEnterprise EC12/BC12

z/OS 2.4 or 2.5

and the appropriate PTFs

– BCP APAR OA63406 with PTF UJ92511 – HBB77C0 for z/OS 2.4
– BCP APAR OA63406 with PTF UJ92512 – HBB77D0 for z/OS 2.5

Re: SMTP and OAuth

[Timothy Sipples]

Echoing prior responses, Jakarta Mail (formerly JavaMail) supports OAuth2. Here 
are some ways to get Jakarta Mail on z/OS:

J1. If you have at least a relatively recent release of CICS Transaction Server 
for z/OS then you should have CICS Liberty with Jakarta Mail. You may also be 
interested in the CICS Event Consumer sample code:

https://github.com/cicsdev/cics-event-consumer

J2. If you have WebSphere Application Server for z/OS (which includes a 
WebSphere Liberty license for z/OS) then you should have Jakarta Mail.

J3. Open Liberty includes Jakarta Mail and is available here:

https://openliberty.io

If you'd like a Liberty distribution *with IBM support* on z/OS then please 
choose one of the first two options.

Python is another vehicle that provides support for sending e-mails from z/OS 
with OAuth2 support. Colin Paice describes how in this article:

https://colinpaice.blog/2023/02/21/sending-an-email-from-z-os/

For more information on the IBM Open Enterprise SDK for Python please visit:

https://www.ibm.com/products/open-enterprise-python-zos

There are probably some other options, but this list is a good starter set I 
think.

AFAIK all currently marketed IBM zSystems servers configured with any 
subcapacity CPs (general purpose processors) — including the very smallest 
A01/401 capacity models — feature System Recovery Boost standard, at no 
additional charge. See here for details:

https://ibm.biz/z15SRBWhitePaper

That said it's typically a "really good idea" to configure machines running 
z/OS with at least one zIIP — and not just for z/OSMF but for myriad other 
reasons.

How batch create a PDSE2 with Generations?

[Charles Mills]

Is there any way to create a PDSE V2 with member generations in batch? I know I 
can do it interactively with ISPF 3.1, and I know I can't do it in batch with 
IEFBR14 and a DD, the way you would create most any other dataset.

It needs to be batch, and it would need to be "pure basic z/OS," because it 
would be part of an ISV product install. (I can't say "you need to download CBT 
whatever first" or "if you have this other ISV product already ...")

Thanks,
Charles

Is batch ISPF an alternative or do generations depend on graphic terminal?

What releases does the OP wish to support?

IS SYALLSDA preferable to SYSDA since the latter is nonstandard?

Why can’t you run the following in batch?

//AF01 DD DSN=&SYSUID..PDSE2,
//DISP=(NEW,CATLG,DELETE),
//UNIT=SYSDA,

[Lionel B. Dyck]

The OP asked for batch, and I assumed, perhaps incorrectly, that he wanted to 
do it with JCL for a vendor product installation.

SYSDA, SYSALLDA, or 3390 - all should work as generic unit types and an 
optional vol=ser=xx may be needed if SMS is not active and/or the dasd is 
not mounted as public.

Doing it using REXX, or some other scripting language, would also work.

Thanks! You're right of course. When I looked and asked about this a couple of

JCL. This is perfect. Sorry for the dumb question. Not sure what I was 
searching for that I did not see MAXGENS in the JCL Reference.

Regarding MAXGENS in the JCL - be sure it is less than, or equal to the 
IGDSMSxx MAXGENS_LIMIT specification.

And you may want to check these (copied from my system):

MAXGENS_LIMIT(256)   
PDSE_RESTARTABLE_AS(YES) 
PDSE_VERSION(2)  
PDSESHARING(EXTENDED)
PS_EXT_VERSION(2)

hi Eric,

There are some good responses already.  My colleague asked me to post this on 
their behalf:


You can use the SKIPSRC(SHOW) option along with any listing option (Ex. SOURCE) 
to show the portions of the files. The EXPMAC option is also helpful to see 
macro expansions.


Hope this helps.

Yep. IMHO a warning message stating that MAXGENS has been set to the

Avoiding IEW2311E

[Neale Ferguson]

When building programs under OMVS and CMS I am getting:

IEW2311E 1361 A NAME STATEMENT FOR MEMBER NOANSI WAS FOUND IN SECONDARY INPUT.

The resulting output is perfectly fine and will execute but it results in a 
return code of 8. I can use -Wl,let=8 but the return code is still non-zero and 
the automated tool (make) will terminate the build.

Is there anything I can do to prevent this?

Tls 1.2 and server authentiaction

[Itschak Mugzach]

Since the last ptfs applied last weekend, The server certificate CN is now
verified by Z/oS (the client).  I know it is a normal behaviour of TLS, but
it has never been performed by z/os before.

Does anyone know which PTF made the change?

Eh? What you're saying makes no sense. Of course the server cert is validated 
by the client. I suspect some root changed; what error are you getting, and 
from what?

IBM is doing better nowadays.

Can a site set the max to 0?

The value is 0 to 2,000,000,000. The default is 0.

We use htwtconn and the message is returned during handshake. It is also

DSNTYPE=(LIBRARY,2)

The 2 is required.

Of course, the OP could use DYNALLOC, or any of the facilities that front-end

Re: Tls 1.2 and server authentiaction

In my limited (non-mainframe) experience with OpenSSL, I think it's up 
to the application to decide whether to check the common name in a 
validated cert with, say, a URL or IP address string.  So it could be an 
older application didn't bother, and a newer one does.  Just guessing.

Not really - Java is just a programming language. Like any language, you 
can run part of your application here and part there if you build a 
communications architecture, have the data in the right places etc. But 
you can't just divide the application without doing the design work.


z/OSMF does actually run part on z/OS and part in your browser 
(Javascript I assume) but the parts that access z/OS services, read z/OS 
data etc. need to be on the mainframe. I doubt there is much that can be 
practically offloaded.


(On the other hand, I think the mainframe side performance could be 
greatly improved. Having looked at the SMF data from z/OSMF startup, I 
suspect the startup time could be cut by 90%+ with a bit of tweaking...)

Re: z/OSMF

I manage 3 sites that each have a z13s with no specialty processors, they were 
deemed unnecessary at the time of the purchase, and at the time IBM didn't 
disclose that shortly afterwards they would be shifting to z/OSMF which all but 
locks them out of installing the next release.  

Possibly IBM should not sell processors that are under powered for the 
mandatory processes, or possibly not force sites to upgrade the processor they 
purchased jsut because IBM has decided that z/OSMF is "easier" than Serverpac.

It would have been smarter for IBM to keep z/OSMF based installation optional 
until the z13s was no longer a supported processor.

I wonder why IBM didn't build z/OSMF to run on a PC and just let it communicate 
to z/OS?  That would have been pretty cool.

IBM doesn't require anyone to order/configure less than 200 MSUs (PCIs) of 
general purpose processor capacity. If you want to order a configuration like 
that go for it!

Bearing in mind that VSEn is important and also exists, and IBM really ought to 
be building machines that also cater to VSEn customers, here's the current 
minimum orderable machine configuration (latest model) for z/OS and VSEn:

* IBM z16 A02 (or AGZ for rack mount)
* Capacity Model A01
* Base CP capacity: 105 PCIs (13 MSUs)
* z/OS System Recovery Boosted capacity (standard/no additional charge): 1,982 
PCIs
* 64GB of usable memory (plus HSA)

Add just 1 zIIP and you get ~1,900 PCIs of full-time zIIP capacity with 2 
processor threads (SMT2). You can add as many zIIPs as you wish up to the 
physical capacity of the machine.

Capacity Model A01 continues to be zELC eligible on the full capacity. Even 
though it has 105 PCIs (plus System Recovery Boost, plus more and far better on 
chip accelerators, plus optional zIIPs) it still qualifies for the same 
software licensing tier that the ~26 PCIs IBM z890 Model 110 did 19 years ago.

I don't see any problem here. If 105 PCIs/13 MSUs (plus a zIIP I suggest) is 
all you need for your z/OS computing, well OK then! That model is available, 
and (in most countries) you can get a nifty rack mounted form factor if you'd 
like. If you need more, OK, that's available too.

Here's the recent history of minimum orderable/configurable CP capacity (all 
Capacity Models A01):

IBM z16 A02/AGZ: 105 PCIs*
IBM z15 T02: 98 PCIs**
IBM z14 ZR1: 88 PCIs
IBM z13s: 80 PCIs
IBM zBC12: 50 PCIs
IBM z114: 26 PCIs

* System Recovery Boost capacity: 1,982 PCIs
** System Recovery Boost capacity: 1,761 PCIs

The z114 was announced in 2011 and the z16 A02/AGZ in 2023. Over that period 
IBM increased the minimum orderable CP capacity by ~12.4% per year 
(compounded), plus SRB.

Re: z/OSMF

[Neil O'Connor]

I used z/OSMF on a z13s from 2018 till the end of 2022. Since then it's on a 
z15 T02. I have not found performance to be an issue. It was really bad in the 
early days before it exploited Liberty Profile, but much better after that.

Neil.
