One thing that might give you problems is WLM. It might behave wonky on a z16 
processor. Is 2.5 even orderable any longer?

HMC access also failed, and the only conclusion I can come up with, is that the

I am working through that debug process, but is there anyway to dynamically

I have an interesting problem I'm looking at and nothing seems obvious as to 
the reason why. On two of our systems when I allocate a new SYS1 dataset, 
non-sms with no DATACLASS assigned by the ACS routines or on the allocation 
itself, when I specify UNIT=3390 it's assigned an EXPDT of today+3 days, when I 
allocate the same dataset on the same volume using UNIT=SYSDA or UNIT=SYSALLDA 
it's not given an EXPDT.

When I do the same processes on different systems in the same SYSPLEX, but in a 
different SMSPLEX, we're not observing the same EXPDT behavior, with no EXPDT 
assigned for both datasets.

Does anyone have ideas on where to look?

Re: What happens in HSM when I change a Management Class

[Allan Staller]

Classification: Confidential


Gadi, Mike has a good point.  Doing HSM tape recycles could help free up any 
tapes with a low number of datasets on them.  This is true for migration tapes 
and backup tapes.  Be warned that if you don't do tape recycles on a scheduled 
basis the process could possibly run for a long time.  As an example, I think 
that could then impact HSM process of recalls from tape.  I believe the place I 
last worked at did tape recycles every day


You might want to consider "sneaking up" or your eventual goal.
Let us say your goal is to eventually get to a 25% recycle percentage.
Day 1 you could do a 5% recycle, Day 2 could be a 10% recycle,

Also, you can issue a HSM RECYCLE command to find out (in advance) how many 
tapes will be included.

BTW, you can also segregate Backup and Migration recycles. By default all tapes 
(Backup and Migration) are included with Migration being processed first.

You should be recycling tapes with a low percent of active datasets.
This copies the remaining active datasets to a new tape then marking this on as 
inactive.  You can manually issue a recycle command against a specific volume.

Re: How to reduce the overhead of WLM?

[Allan Staller]

Classification: Confidential

The most important resource in most shops is CPU and is usually the critical 
factor in WLM adjustments.
Judicious user of SC period and IMPortance is far more effective in controlling 
the distribution of CPU.
.
I would not overload SYSSTC with work, this will prevent WLM from servicing 
really critical stuff (GRS, XCF, IRLM,..).
However it’s not my dog.

Another thought to the OP. Are you trying to reduce overhead because of a CPU 
shortage, or just curious? Think absolute value vs percentage.
In Sandbox environments, very often something like WLM appears to be the 
largest consumer of CPU), but in absolute terms it is really minor.

If you are running a lot of CICS regions, you might want to look at reducing

Re: How to reduce the overhead of WLM?

[Allan Staller]

Classification: Confidential

1) reduce the number of service class periods and service classes
2) reduce the numberf of workloads
3) set CICS MAXTASKS to a reasonable number
4) Since this is a development system, set your major subsystems to velocity 
goals, not transaction goals (IMS, CICS, DB2, MQ)

This is a combination of experience and remembrance from a WLM training class.

Most people try to over-control WLM instead of letting it do its thing.\

This is probably a strange question, but is there a way to reduce WLM cpu 
usage?   Here's the situation:

- The system is a lightly used development system.  Unless something is in a 
loop (very rare), CPU % probably is usually less than 10%.  And except for 
system regions & CICS, it's rare to have multiple jobs running concurrently.
- Only one processor defined to the VM. No ZIIP either.
- We are charged for CPU cycles.
- WLM is the highest consumer of CPU.  JES2, TCPIP, ZFS and SDSFAUX round out 
the top 5 consumers.

There is a lot of information about WLM tuning, but as best I can tell almost 
none of it relates to reducing WLM usage.

From reading the Init & Tuning manual, I'm trying these settings:
AIMANAGEMENT=NO
HIPERDISPATCH=NO
CCCAWMT=45
RMPTTOM=15000

I was thinking that perhaps reducing whatever processing intervals I could 
might help.  But I can't tell these changes made a difference.  (I don't have a 
tool to measure WLM usage.)

Any suggestions would be appreciated.

TIA,

Wendell

I believe that the only things that must be PDS and not PDSE are libraries 
accessed at IPL before DFSMS has started the PDSE address space(s).

I know you can use a sequential dataset for the TCP/IP profile, and I’m pretty 
sure you can put it in a Unix file too.

You will, at some point need to restart TCPIP to pick up the new PDSE in the

TYPE 1 PDS/E is sufficient for this purpose.

I could not find definitive doc saying a PDS/E was/wasn't allowed, but I am 
convinced it is. Thanks.

Over the weekend I created a PDS/E and copied the members, made my update, and 
I'm awaiting Change approval to do any Obey from the new Library to pick it up, 
temporarily. Then the plan is to change the TELNET proc to point to the new 
Library. Over the next several weeks I expect IPLs will pick up the Library. 
Until then we will be slightly on uneven ground.

I read about two different types of PDSs, type-1 and type-2. In a z/OS 2.4 
shop, do we need to specify or is type-2 created by default?

Thanks again!

I believe HLIST LEVEL() Backup will provide the information you need.
Certainly the HLIST DA() backup will provide the same info if HLIST 
LEVEL(xxx) is unsupported. (I did no look up the syntax).

From there you can generate HBDEL commands (remember to specify date/time or 
all backups will  be deleted. \
You stated you only wanted to delete backups from a specific volume.

I can't think of any way to select the specific volume without a 3rd party add

Dave,

I was told the same thing 54 years ago when I starting working at CalTrans. 
Managers would just be able to code in COBOL PROFITS = SALES - EXPENSES and we 
would all be out of a job.

Of course, there are more programmers now  than at any time in history.

The question of assembler comes up from time to time, and the question has more 
nuances than you might think.

As it turns out, there are lines of code and lines of executed code. What that 
means is that lines of code that are executed frequently are seldom written in 
a compiled language but are instead written in assembler.

A good example is sort. In the 1970s sort typically used about a third of all 
processor and channel resources on a mainframe. Today that number is far lower, 
in the mid-teens despite the fact that much more data is being sorted.

The reason for this is that some very brilliant assembler programmers at 
SyncSort and the  IBM Dfsort team wrote code to highly optimize sorting and 
related functions. I’m counting PL/S as essentially assembler in this instance.

The same is true at BMC Software and my own company Phoenix Software 
International: highly optimized assembler code greatly improved performance.

Even though there are almost uncountable lines of COBOL code, it makes for a 
tiny fraction of executed code. Most compiled languages execute a few 
instructions and then invoke a CICS, IMS, or DB2 function.

Starting in the 1980s, corporations the world over began to understand that it 
was much more cost-effective to buy or lease software from a vendor than 
develop it in house. These developers left the end-user companies and went to 
software houses where they primarily write in assembler. Now ever piece of 
software usually has parts that are not performance-sensitive, so they might 
get written in C++ or Rex or some other compiled language.

I’ve grown up with software, having written my first program in 1960.

Assembler won’t be gone in five years or anytime can the foreseeable future.

So I would revisit your thoughts.

Michael,

I do not think it requires the C/C++ compiler to use the C RTL subroutines 
delivered in CEE.SCEELKEX.  You only need the C/C++ documentation to look up 
the routine names, though working out how the C "header" files define the 
parameters and return value and translating those to COBOL would be challenging 
without the headers installed.

Is any large commercial shop actually NOT licensing the XL C/C++ compiler these 
days?  I would hope the cost is not be so prohibitive as to bedevil the 
bean-counters looking for $$ savings.  Don't at least some vendor products 
coded in C/C++ require at least the RTL subroutines (and maybe also the C++ 
DLL's) installed in order to execute at all?  Or is that all delivered in LE?

[CAUTION: This Email is from outside the Organization. Unless you trust the

which can steal your Information and compromise your Computer.]

I'm not a sysprog (just a security geek), but I can at least allocate datasets, 
and at the start of this year it fell to me to allocate a new dataset in which 
are logged all changes made in the security system.  Past year's log are in the 
12000-track range, so I started with a smaller allocation while I took the time 
to talk to our sysprog about space requirements.  It's populated from a daily 
production job, by the way.

When I re-allocated it, on his advice I tried a multi-volume and extended 
allocation (PS-E).  Almost immediately the job started bombing, claiming that 
the first four volumes it tried didn't have the necessary space to add an 
extension.  The sysprog is puzzled - says it should have looked in volumes that 
DO have the space, not the ones that don't.

Second attempt (I don't count the temporary smaller allocation) I kept PS-E but 
dropped the multi-volume requirement.  I've never done one of those anyway, and 
don't trust 'em.  The system promptly dropped the extra tracks I allocated, and 
a day or two later the job started bombing with a B37-04.

Third attempt: Forget PS-E (I'm unfamiliar with that too) and just used 
SPACE=(TRK,(9000,1000)).  That seemed to work for a whole week, but I just 
noticed that something, somewhere, has released extra space AGAIN; 3.4 tells me 
it's now 1960 tracks and 83%.  The job isn’t bombing yet; some time later in 
the year I'm guessing it's going to.

Pardon my frustration: WHAT THE HECK IS GOING ON?  Why does it keep releasing 
space although I never specified RLSE?  The sysprog doesn't know either - but 
he's an external contractor who just took over the system a few months ago and 
if it's something simple he may not be aware yet of ... I dunno, something in 
SMS maybe?

Some wrinkles that may or may not be relevant:

1) The dataset is written using a REXX exec that calculates the DSN by 
reference to the current year.  This relieves folks from having to update the 
JCL every year, but maybe something about the way the exec does the allocate is 
causing the problem?  I'm guessing not, because as far as I now this job has 
run correctly for years.  But just in case:

  "ALLOC DDN(CHG$$OT) DSN('') MOD CATALOG REUSE",
  "SPACE(300,30) CYLINDERS RECFM(V,B) LRECL(304) BLKSIZE(27998)"

2) I don't know anything about SMS, but could something there be releasing 
space?

3) What IS extended PS, anyway?  I'm told it allows more than 16 extents, but 
a) how many more? And b) how else is it different?

4) I allocated the dataset each time using not batch JCL but 3.2 ... expecting 
there's no difference.

I am trying to debug a situation in zSecure where I am getting this message 
from the CKNSERVR address space.

CKN017I 12 BPX1AIO connect failed on socket 1 RC 111 permission denied, reason 
7663 730Cx

   Port 7173 of 192.168.11.100

BPX1AIO documents that its return and reason codes are in the UNIX messages and 
codes manual.

I am looking in manual SA23-2284-60 but the values for errnojr only go up to 
7371.

Where can I find the documentation for higher values?

Re: JES2 JOBDEF DUPL_JOB=NODELAY - Any gotchas?

[Allan Staller]

Classification: Confidential

Not sure it will help. GRS may deadlock on resources between the jobs. Even if 
GRS does not deadlock, it will still delay the 2nd and subsequent jobs.
All you will likely do ius mod the delay from the JES jobqueue  to the JES 
execque.

I am not a sysprog but I occasionally play one in my spare time. I am thinking 
of changing a system that I control to DUPL_JOB=NODELAY. Any gotchas? Anything 
I need to consider before I do this? Do most/many of you run with NO_DELAY?

I am trying to solve a problem where I have jobs delayed because the names are 
duplicates. I can't easily change the jobnames.

I can't think of any issues. We don't have any significant automation. I can't 
think of anything where jobs are referenced by name rather than Job ID.

What should I be considering?

Thanks,
Charles

Hi,

You can check the jobclass definitions of your STCs by issuing 
$DJOBCLASS(STC),LONG or looking into SDSF at JC screen. Probably the outdisp is 
(PURGE,PURGE).

In this case, you may change it to (HOLD,HOLD) to see the JCL.

Looks like a fairly new SSH vulnerability has surfaced...Anyone figure out a 
local remediation for this yet?   As per usual, IBM is mum.   There is no 
fixing PTF yet based on what I see in ResourceLink.


QID

38913

Severity

HIGH

Definition

SSH Prefix Truncation Vulnerability (Terrapin)

Description

The Terrapin attack exploits weaknesses in the SSH transport layer protocol in 
combination with newer cryptographic algorithms and encryption modes introduced 
by OpenSSH over 10 years ago. Since then, these have been adopted by a wide 
range of SSH implementations, therefore affecting a majority of current 
implementations.





QID Detection Logic (Unauthenticated):



This detection attempts to start the SSH key exchange process and examines 
whether either of the vulnerable ChaCha20-Poly1305 Algorithm or CBC-EtM 
Algorithm is active. It subsequently verifies whether Strict Key Exchange is 
enabled. If a target is identified as vulnerable, it indicates that the target 
supports either of the vulnerable algorithms and lacks support for Strict Key 
Exchange.

Solution

Customers are advised to refer to the individual vendor advisory for their 
operating system and install the patch released by the vendor. For more 
information regarding the vulnerability, please refer to Terrapin Vulnerability



Patch:



Following are links for downloading patches to fix the vulnerabilities:

OpenWall Security Advisory

Impact

Successful exploitation of the vulnerability may allow an attacker to downgrade 
the security of an SSH connection when using SSH extension negotiation. The 
impact in practice heavily depends on the supported extensions. Most commonly, 
this will impact the security of client authentication when using an RSA public 
key.

CVE-2023-48795

SSH Prefix Truncation Vulnerability (Terrapin) detected on port: 22

[CAUTION: This Email is from outside the Organization. Unless you trust the

which can steal your Information and compromise your Computer.]

I have two systems that I want to share dasd and allow for VSAM RLS between the 
systems, but I don’t want to SYSPLEX JES2.  I have MASDEF SHARED=NOCHECK.  What 
else can I do to un-sysplex JES?

Is it safe to delete the JES2 and/or SYSJES group definitions from XCF?  I 
don't have a JES_CKPT_1 structure defined at all.

Background:

I’m trying to add a z/OS 3.1 ( S0W1) to a sysplex where z/OS 2.5 
(Z3- S0W3) is running, but ONLY for VSAM RLS.  I don’t want to “plex” 
anything more than is needed for VSAM/RLS—not JES, not SYSLOG, not VTAM, not 
SMF or anything else.

The systems are running fine stand-alone (each with their own set of disks, 
including the volume with the CDS), but when I try to use the same CDS disk 
between the systems, the first system comes up fine, but JES2 on the system 
brought up last complains that it cannot find the checkpoint datasets of the 
OTHER system:

Z4  : H *$HASP284 JES2 INITIALIZATION CHECKPOINT DIALOG STARTED

Z4  : H   CKPT2=(DSNAME=SYS1.HASPCKP2,VOLSER=B5CFG1,INUSE=YES)
Z4  : H *
Z4  : H   VALID RESPONSES ARE:

LISTED
Z4  : H'TERM' - TERMINATE JES2 INITIALIZATION ON THIS MEMBER
Z4  : H *04 $HASP272 ENTER RESPONSE (ISSUE D R,MSG=$HASP277 FOR RELATED MSG)

"Z4" is the z/OS 3.1 system.  The “B5SYS1” and “B5CFG1” volumes belong to the 
z/OS 2.5 system.  If I bring up z/OS 3.1 with z/OS 2.5 down and then try to 
bring up z/OS 2.5, the same message is displayed except it identifies the 
volumes belonging to the other system.

I can RECONFIG with the correct CKPT volumes, but it always ends with:

Z4  :  $HASP478 INITIAL CHECKPOINT READ IS FROM CKPT1
Z4  :   (SYS1.HASPCKPT ON A3SYS1)
Z4  :   LAST WRITTEN THURSDAY, 18 JAN 2024 AT 21:57:08 (GMT)

Z4  :  $HASP792 JES2 HAS JOINED XCF GROUP JES2 THAT INCLUDES ACTIVE MEMBERS

Like I said, I don't want a MAS at all--each JES2 should be separate.


(This has already gone too long, but here are some displays that might help:)

Gentlemen,
First, thank you for your answers. I appreciate it.

Regarding TOLENQF - it doesn't work with COMPRESS or CONSOLIDATE. The manual is 
clear here.

Regarding rename - this is the thing I wanted to avoid for several reasons:
1. There is some risk to rename wrong "copy" of the dataset, or alter ICF 
entries for wrong copy.
2. Valid copies are located on non-SMS disk, but cataloged out of regular 
catalog search (SYS1.name in some UCAT). Plus some aliases, etc.
I want to not destroy it.
3. I don't know how to rename such datasets! Yes, I could imagine access from 
another z/OS image, but it would be a series of manual ISPF r command. 
Non-repeatable, error prone. Is there any tool allowing to rename such datasets 
in batch? Wildcard support (i.e. REN SYS1.* SYS2.*) would be welcome.

Stop OAM?
Export VOLCAT?
Delete VOLCAT
ALLOCATE new VOLCAT.
IMPORT from Exported copy?

Is this right, anyone have JCL example of EXP/IMPORT of a volcat?

This is a severely manual process.
The PTFS/APARS can be determined from the HOLDDATA.

The PTFs are individually orderable via ShopZ (just like any other PTF). The 
only difference is that the PTF/APAR information is only available in the 
HOLDDATA.

I have already searched there and did not find anything related to this 
particular vulnerability.  I did find one PTF from 2023 which is for ssh.  That 
PTF is applied on our sandbox LPAR, scheduled to be rolled out into production 
shortly.  Also, the IBM documentation for z/OS 2.4 SSH states that it is based 
on Open SSH 6.4p1.  Which I think is quite old.

Re: Starting up a LPAR for the first time joining a parallel sysplex

Nothing major on the 1st 2 points. LPAR1 cannot join the sysplex until GRS= in 
IEASYS00 is updated to (at least) TRYJOIN.

We are building a parallel sysplex.

LPAR1 is still in a monoplex with GRS=NONE. It will be shutdown. Then we want 
to bring up LPAR2 with GRS=STAR and join the sysplex.

A couple of questions cropped up.

1. Can LPAR2 be brought up, trying to access the share catalog, RACF database 
etc when the other LPAR is not up. What are the gotchas to be looking for 2. 
This will be the first time the LPAR is IPL'd with GRS=STAR and trying to join 
the sysplex.  Would that extend the time for the IPL and what would you be 
looking for during the IPL?  Would it take 2-3 hours to be confident it was 
working - e.g. CDS are okay, an all other parallel sysplex configurations?
3. What happens when LPAR1 comes up and then joins the parallel sysplex?


Thanks

Hi all,

Just looking for opinions on this.

Scenario is we're running z/OS 2.4.  We don't have zOSMF installed.  Sometime 
next year we're going to migrate to 3.1.  Would we be better off 
installing/implementing zOSMF 2.4 today in preparation for installing 3.1 or 
should we install zOSMF 3.1 and implement that before installing z/OS 3.1?  Can 
we even install zOSMF 3.1 without having a running zOSMF install already?

Thanks,

Rex

Re: JES3plus & TDMF

[Allan Staller]

Classification: Confidential

From the APAR numbers, they are ancient and most likely do not apply to ans 
z/OS system (OS 390 or earlier perhaps).
That coed is undoubtedly in the JES3 and Jes3/Plus base. I would not worry 
about them.

One other thing. TDMF can move inactive page datasets. It will refuse to touch 
an in-use page dataset.

The last time I did a DASD migration, I defined temporary page datasets and 
used pageadd/pagdel commands to move the paging activity.
After the original page datasets had been moved, I repeated the process to go 
back to the original page datasets.

[CAUTION: This Email is from outside the Organization. Unless you trust the 
sender, Don’t click links or open attachments as it may be a Phishing email, 
which can steal your Information and compromise your Computer.]

Apologies for the double listing to anyone who's also seen this on the JES3-L 
LISTSERV.

The government agency that employs me has three z/OS LPARs (V2R5) running on a 
z15 server. The lone mainframe storage subsystem is a non-replicated, 
channel-attached DS8886. This has never been a JES2 installation and Phoenix 
Software’s JES3plus is now installed. While the JES3 initialization deck has 
DEVICE statements for all tape drives, it has not contained a DEVICE statement 
for a DASD address in over a decade. In other words, DASD allocation is not 
managed by JES3.

The DS8886 will soon be replaced by a DS8950F. TDMF software will be used to 
migrate the contents of the DS8886 to the DS8950F. I believe that TDMF can move 
the JES3 SPOOL volumes, the SYSRES volumes, the page packs and the DASD volumes 
where the coupling facility resides without issues. A co-worker insists that 
all of the LPARs must be brought down, separately, so that each LPAR’s 
‘sensitive’ volumes can be moved from another LPAR.

IBM documents state: ‘JES3 considerations: In order to ensure that JES3 system 
defined volumes will migrate (not required for a Point-In-Time migration) in a 
TDMF (or P/DAS) environment, APARs OW23271, OW28455, and OW28457 must be 
applied. These APARs provides JES3 DDR support for P/DAS and therefore, will 
allow the swapping of volumes. Important: All systems sharing devices where 
JES3 manages the devices must be involved in the TDMF session running. This 
ensures that all JES3 internal tables are properly updated. Failure to do so 
will cause unpredictable results. It is recommended that the user check the UCB 
for the following bit prior to copying volumes in a JES3 environment: UCBJ3DV - 
device is defined to JES3. If the bit is off, TDMF will migrate the volume(s) 
with no errors. If the bit is on, TDMF will make the appropriate calls to JES3 
to notify JES3 of the volume redirection needed.’

Since the DASD volumes at this installation are not managed by JES3, I don’t 
think these APARs are an issue. However, to assuage my co-worker’s fears, I’d 
like to see whether the corresponding PTFs have been applied. Unfortunately, I 
cannot find the PTFs that correspond to any of them.

Question: What PTFs correspond to APARs OW23271, OW28455, and OW28457?

Also, I’m not sure how to display the UCBs involved to verify that the UCBJ3DV 
flag indicates that the volumes are not managed by JES3. Any help you can 
provide on would be appreciated, particularly on how to use either UCBSCAN or 
UCBLOOK macros.

(This is not specific advice but a way of thinking about things.)

SQA can, of course, overflow into CSA - with no real harm done. Unless it 
causes CSA to go short. (CSA can't overflow into SQA, of course.)

The above statements are true for both 24-bit and 31-bit.

1409K below the line, though, is pretty extreme - for 24 bit. If you made SQA 
larger so that it only overflowed, say, by 100K there would be no wasted 
virtual storage.

More importantly, check out the "free CSA" picture. You really don't want to 
run out of that. For 24-bit you want a few hundred K free. (But to achieve that 
might require losing 1MB of 24-bit private, which might not be consequence 
free.)

For 31 bit I like to see at least 100MB free ECSA, preferably more. The reason 
is because ECSA is - in my experience - more volatile.

Speaking of volatility, you need to plan defensively - as a problem can lead to 
surge in SQA and CSA usage .

Final point: I would advocate using SMF 78-2 to build a picture of common 
storage usage - and how variable it is. Here is a blog post I wrote on the 
matter:

htt ps://mainframeperformancetopics.com/2020/01/05/how-i-look-at-virtual-storage

Unless things have changed, SMS does not control temporary datasets. The system

In those days, the limit on bus/tag cables was 200 ft (cumulative). IIRC, that

De-installing the 2503 saved about 125 ft.

Bob Bridges wrote about his history with keypunches.

Mine started in 1965, when I was four. My dad was working on his first 
concordance, of Beowulf, and my mom was going to do the data entry of the text. 
(They'd met in the 50s when he was working for a CIA front doing translation 
and his typist quit. He told them, "I need a new typist, but don't give me 
anyone interesting", and when they brought her in, he thought, "Dammit, nobody 
listens to me around here!" Nine months later they were married.)

So I got to play with a keypunch at a very young age, and then again starting 
in 1975 when I sat in on my dad's PL/C class at the University. I have fond 
memories of playing outside with a bag of chad (please, not "chads"-it was a 
mass noun for 50 years; the 2000 election instantly made it a count noun, but 
we old-timers don't have to put up with that). (Jeez, even Office thinks it 
should be "chads". Kids today.)

Bob, your musing about communications parameters sounds like full/half duplex.

As for the cost of cards-I bought a few boxes on eBay about a decade ago. Even 
then folks were often selling individual cards for several dollars. I still 
have a bunch. My dad always had them in his breast pocket for note cards. He'd 
also always heard that they were the same size as old U.S. bills, but in the 
pre-Internet era had no easy way to verify that. Until one day in the late 80s, 
walking in lower Manhattan, he passed a numismatic store that had an old $1 
bill taped to the inside of the window. He instantly whipped out a card and 
held it up, and sure 'nuff, it was the same size, modulo the clipped corner, of 
course!

Keypunches persisted at University of Waterloo until the early 80s, not because 
the U was backward, but because ONE prof (not my dad!) insisted on using them. 
IIRC the I/O operators (remember them?) tried various stunts, like 
"accidentally" dropping his box of cards (only it wasn't really) in front of 
him and then stepping on them as they went to pick them up. They finally 
managed to get approval to tell him HE would have to pay for the maintenance. 
That cured it.

Re: IBM APAR Names

[Allan Staller]

Classification: Confidential

In my experience, the 1st letter of the APAR name is a "version" designator.
e.g. JES2 has historically had many variants of a "single product".

So the APAR "documentation" designation would be OAx.
An actual "APAR FIX" (with test code) for the "1st version" would receive an 
actual apar number of AAx (x is the same number).
Due to code changes between the releases, a 2nd version is required. (i.e. same 
problem, different code). The "2nd version" would receive the designation 
BAx.
After the vetting process is completed, A PTF (or several) will be issued with 
UA SUPing the relevant APAR number).
e.g.  ++PTF(UAx) SUP (AAx, BBx).

Re: Does IBM file manager let you access panvalet

[Allan Staller]

Classification: Confidential

That is not an option I would undertake.
Last I heard both Panvalet and Endeavour are both CA (Compuware)  which is what 
prompted the bill,
And the question in this thread.

My opinion is that BMC is behaving like the CA of the late 80's, early 90's.
How many installations decided to dump CA at that time?

Your other option is to convert Panvalet to Endevor (easy to do as Endevor 
supports the 10 character names that Panvalet has).  Either way it wll be much

Re: DVIPA question

[Allan Staller]

Classification: Confidential

My presumption is that a data-sharing partner "myserverb" is up and running on 
LPARB. In this case, the transfer is pretty much unnoticeable.

After the transfer of the DVIPA, all new traffic will be routed to 
LPARB/myuserverb. LPARA/myservera will 'wither on the vine.
If LPARA/myservera are shut down too quickly, any users connection to 
LPARA/myservera will be terminated prematurely and cause a perceived outage.

Some situations may require manual intervention.  That that could be done 
through automation.

Some situations may involve noticeable outage outage to the user.


It all depends on how it is setup and how you want to move the task.

Say you have LPARA and LPARB and task "myserver" normally runs on LPARA.

Do you want it to move to LPARB only when LPARA is shutdown and move back when 
LPARA comes back up?

Or do you want to be able to move "myserver" to LPARB while LPARA is still up?

Or a both?

Do you want to prevent "myserver" from running on both at the same time?

You may want to read up on how  TCPIP's Sysplex distributor works.  Although it 
is designed so to have multiple server tasks up at the same time, you can use 
it and just have one task up and running.normally move it from one LPAR to 
another as needed.

DVIPA activate/deactivate isn't seamless. First, it would require the 
application be running on the second LPAR running in standby mode. Second, 
current connections are interrupted unless the application has been designed to 
circumvent the problem. Third, you still have a time frame where the

Each situation is different and a decision about which method best solves the 
problem must be made. The OP said his application can only be active on one 
LPAR. In that case, using activate/deactivate would not provide an advantage

John Giltner says he stops his app on one LPAR and starts it on another. He 
implies that he is not issuing activate/deactivate for the DVIPA address. It 
would make more sense for IBM to automatically deactivate the address when it 
has no ports in use and to automatically activate it when the first listener 
starts.

There are times when activate / deactivate command is needed. For instance, you 
may have applications running in case of failover recovery but you don't want 
them used until the other system fails. Recovery would only need to activate 
the address without the need to startup the applications and resources.

My apologies, I didn't mean to stir up the hornet's nest of opinions on the 
viability of my question.

I will "grossly" explain what I want to do.
I am not interested in other methods, I have other methods, but I am interested 
in this method the most, if it can be done.

Program A executes and sets a global symbol to a certain value and terminates.
Many other jobs execute and, in each one, as needed, the programs check to see 
if the global symbol is set and, if it is, to what value.
They then make logic path decisions within the program based on the value of 
the global symbol.
Finally, Program B runs, or maybe it's just Program A again, and the global 
symbol is deleted.

So, my question is, still, is it possible to define SET symbols from within a 
program?

Thanks, again, in advance for any *constructive* assistance.

The way I read the OP's response, he says everything is handled in the OSA and

Agreed, however it seems the OP is operating in a "toggle-plex" i.e. either 
LPAR A is running or LPARB is running. In this case, the DVIPA would be 
deactivated on one of the LPARS and switched manually via the V TCPIP command 
to activate/deactivate the DVIPA on LPARA or LPARB.

The "old LPAR" will automatically switch to backup mode when the "new LPAR" is

If the VIPA is set correctly, then the data can dynamically move between the 
two LPARs so the workload is balanced across the two LPAR servers.  I did that 
with MQ and shared queues.  Messages rotated between the two MQ managers and if 
one system went down, the other system continued to handle the message traffic.

That is exactly the situation, The second LPAR will be on the same CEC as the 
first, share OSA adapters and be in a sysplex with XCF being the mechanism to 
share the VIPA information. From my reading of the docs, when the server 
application on the primary LPAR is shutdown, and an incoming transaction 
arrives for it, TCP on the second LPAR will see the primary host and 
dynamically route the transaction to the server on the second LPAR. By making 
it dynamic we don't hae to worry about automation moving the VIPA, we can let 
TCP do that.

The second LPAR will be in the same subset as the first.

turning on RMM in protect mode.

My original plan was to us TMSINIT to remove CA-1 and disable the PROC

Or do I need to move it's SVC, re-IPL and not start TMSINIT and then start

Hi,

doesn't work if BCPii is not started.

Mainview (LPARACT view) or Sysview (PRISM command) are able to retrieve this

Is somebody could help me to understand how products like Mainview or Sysview 
are able to retrieve the weight of a LPAR without BCPii ?

DB2 Utilities got sold a vendor and the devs moved with it. I heard an amusing

CICS team in Hursley referred to it as “oh oh PL/X”. It was in the 90’s when 
everybody thought inheritance was a good idea but it introduced “is-a hell” and 
the path length of the code exploded. It was so bad that DB2 utilities were 
close to missing their targets and abandoned it. It was a huge blunder. A lot

Linux (nor Unix) does NOT have any maint systems. P in RPM stands for Package 
which is the z/OS equivalent of product / component. Complete packages are 
replaced regardless of the problems you want to fix. Every package has a 
version number which is indentifies all the maintenance included in that 
package.

> To me YAST (the Linux equivalent of SMP/E) handles upgrades

YAST and SMP/e have nothing in common. YAST tells you it's about installation 
and configuration. It's about replacing the entire package and nothing to do 
with maintaining that package. The M in SMP/e stands for Maintenance. You never 
see a PTF that is 1MB. The only reason SMP/e installs, is to create a 
maintenance environment for the product / component. If installation is your 
only requirement, then use a different tool like IEBCOPY, DFDSS or ???.

> Each product/component has its own main entry and dependencies.

Unix dependencies are by version number and have nothing to do with the package 
(product/component) in question. The package is completely replaced. SMP/e 
dependencies can be for entities within the same function, other functions, 
PTFs and APARs. A function is the SMP/e equivalent of a Unix package.

> I thought it was a fairly good replacement for SMP/E for the Linux

> I can see how it could be used to do z/OS and related.

YAST, RPM and other Unix package installers are unacceptable replacements for 
SMP/e. Name 1 z/OS customer that is willing to risk reinstalling an entire 
product/component because they need 1 PTF. Add to that cascading product 
installs because of dependencies. Worse than that, testing must include 
everything that changed in those installs and every product/component that 
interacts with all the installed products/components.

I think z/OS uptime is 99.%. You get what you pay for. Unix maint 
philosophy may be acceptable on $10,000 computers but highly unacceptable on 
multi-million $ computers. We don't tolerate unintentional downtime.

2. Is there any way to fix it without reIPL?

In that case, either the capacity  (or weight) of the LPAR will need to be 
increased, or as another suggested, give access to another CP.
The only other thing you can do is get with the DB2 folks to see if they can do 
something with the restore process.

Ok. You zre using 2 period TSO Service Defs. I suggest you adjust the period 1 
duration until 96% (vs. 90%) of transactions end in period one. 
There is no easy way to measure this in advance. The RMF Service Class Period 
report will however show the results after the fact.

Increase the duration of period one and look at the RM report. Wash, rinse, 
repeat until the desired goal is achieved. Beyond that, I do not believe there 
can be much done. IIRC the DB2MSTR address space either runs at IMP 1 or in the 
SYSSTC service class. 

Speculating (I am not a DB2 expert) if commits can be take during the restore, 
it might help.

Wish I could help more.

We're migrating our CF processors from z13's to z15's. One of the CF LPARs on 
the z13 is assigned 1.5GB. There are no structures there, it's just used as 
placeholder for STP timing links. Will that LPAR activate on a z15 processor 
with the same 1.5GB allocation, or will we need to bump it up some?

Re: z/OS performance question

You did not say where the TSO response time issues were being observed. I 
suspect, from the information provided it is on SC08D3(possible) or SC14D4 
(most likely).

If you look, I suspect the majority of CPU consumption is from the *MSTR DB2 
address space. DB2 will charge this back to the "user". This address space is 
most likely running in the SYSSTC Service class.

I suggest you look at the service class definitions for TSO. At least 80% of 
all transactions should end in TSO Service Class Period 1, 80 % of the rest in 
TSO Service Class Period 2  (16%) and the remainder in TSO Service Class period 
3 (4 %). Another variation could be TSO Service Class Period 1 at 96% and TSO 
Service Class Period 2 4%; No TSO Service Class Period 3.

Depending on the scheme chosen above, except for the last TSO Service Class, 
all should run as importance 1. They may have different performance goals, but 
the importance should be 1.

Let me start off by saying I am not a z/OS performance and capacity planning 
expert. If anything, I am a novice. I am looking for a trivial answer to a 
non-trivial question.
We have a z15 (8562-T02) running three z/OS 2.4 LPAR's, Production (SC10D1), 
Development (SC08D3), and Sysprog (SC14D4). Below is information from the RMF 
Partition Report. My question/problem is this. On the Development LPAR, when a 
DB2 database restore job runs, the MVS Busy goes to 100% as seen from both SDSF 
DA and RMF CPU reports. Most of the CPU Busy goes to the DB2 restore job. The 
batch job runs in a discretionary service class, and TSO users run in a higher 
service class with goal mode. But, response time for the TSO users gets long, 3 
to 5 seconds between enter keys, ISPF screen swaps etc.. Normally the TSO 
response time is sub-second. As you can see, the Development LPAR has one 
Logical CP defined. Based on the capping characteristics of Development as 
displayed below, would adding another Logical CP help TSO response time?

I must disagree here. This is just a different implementation of the existing z 
architecture.
There may be some minor omissions, but I see nothing new here.

FLEX has been around for quite a while, and was always about z-emulation on an 
x86 chip.

It does provide some low-end relief for those that require less than the 
minimum z/16 horsepower.

I don't know.

My understanding is that Fibre Channel is an evolution of SCSI which is 
supposedly a somewhat intelligent controller wherein the OS asks said 
controller to fetch / store some data for it.  As I understand it, the OS & 
main CPU aren't involved in the transfer beyond asking the controller to do the 
transfer on it's behalf.

comes into play vs the CPU's involvement in the transfer to / from the 
controller.

But between the controller and the back end drive, as I understand it, the CPU 
ins't involved.

So I can't say that "a rack of x86 servers connected to a SAN using fibre 
channel" isn't using channelized I/O.  I think in many ways they are.

This is a place where minutia matters.

This is great to hear, John. Thanks.

For people like me, who need excruciating clarity, you're saying that the 
SERVER in the Co:Z product groks traditional datasets as well as USS files. 
Correct? Fantastic!
That means one can use a variety of clients, specifically several which go via 
SSH. Is that also correct?

You mention SFTP which is FTP-like behavior using SSH under the covers.
Contrast with FTPS which is traditional FTP but with SSL/TLS added.
I'm keen on the former because it uses a single channel. Though I much prefer a 
one-shot command in any case, and 'scp' does that (and runs via SSH like 
'sftp').

Does the Co:Z server speak both SSH (for SFTP) and traditional FTP?

PMFJI here, but when I heard some years ago that z/OS dropped support for 3215 
keyboard/printer consoles it occurred to me to ask what the users of z/OS under 
z/VM were supposed to do to easily automate console logging/monitoring and 
automated IPL/shutdown external to z/OS?  Maybe more recent z/VM’s have 
facilities I am not aware of that can directly capture output from and interact 
with 3270 devices better than in older versions, but I haven’t seen anything in 
this thread that would support that speculation.

Why withdraw support for a simple to use and simple to automate console 
interface that Just Worked (tm)?  It never made any sense to me.  Maybe 
z/OS-centric hubris (automation can only happen inside z/OS, do it our way or 
hit the highway, dude)?

This is z/OS 2.4. What does "not supported" mean per se? It comes up fine, just 
the output is fugly. And I'm 99.44% sure that wasn't true on our previous

Well, I read that paper. Lots of assumptions in there about z/OS knowledge that 
I don't have, like where it talks about "V CN(MVS0MAST),OFFLINE". I have no V 
(I assume that's VARY?) in any of my CONSOLxx members.

I do have a CNGRP00, which contains:
GROUP  NAME(MSTGRP)
   MEMBERS(S0W103D0,S0W10FFF)

Now that's 3D0 and FFF: 3D0 is a DASD. Seems wrong? The INIT in CONSOL00 is 
INIT  CMDDELIM(;) AMRF(N) MONITOR(DSNAME) CNGRP(00) so it's looking at that 
console group. If I change the 3D0 to 3E1 to match the actual console address, 
is that likely to help/hurt? What I'd rather not do is kill the beast and 
require help from our hosting service--not that they won't help, but we'll have 
to wait at least a bit for that.


(BTW, a nit: "Screenshot 1 - z/VM Login Screen with Dial Command" on page 6 has 
no DIAL command on the screen)

Hi,
We are in the process of installing z/OS v2.5 from z/OSMF.
One of the first jobs uses GIMUNZIP to create the new z/OS libraries.
When the job got to the SMPPTS library, we got these messages:
GIM43501S ** THE CALL TO THE BPX1WRT SERVICE FAILED WHEN PROCESSING
 
/tmp/izud-V110AVN-T1314651/unzip/smpe2023201100726173157/S0354.CB.S0354.CB.ST252475.SMPE.SMPPTS.pax.Z.
 THE RETURN
 CODE WAS '0077'X AND THE REASON CODE WAS 'E329'X.
GIM47800S ** AN ERROR OCCURRED WHILE GIMUNZIP WAS PROCESSING ARCHIVE 
ZSMSP9.CB.ST252475.SMPE.SMPPTS.
GIM20501IGIMUNZIP PROCESSING IS COMPLETE. THE HIGHEST RETURN CODE WAS 12.

Before the GIMUNZIP step, the job allocates a new ZFS and is supposed to mount 
it at /tmp/izud-V110AVN-T1314651/unzip, but from what I can see, this is does 
not happen, and the files are restores to /tmp, which does not have enough 
space.

The job includes some shell scripts that are supposed to mount the ZFS, but it 
doesn't look like they are running.

The step looks like:
//MOUNTEXEC PGM=BPXBATCH,COND=(0,LT)
//STDPARM  DD *
SH ;
mpdir=/tmp/izud-V110AVN-T1314651/unzip;
dsn='V110AVN.SWDEPL.T1314651.ZFS';
if   -e "$mpdir" ¤; then;
  rm -r $mpdir;
fi;
if   ! -e "$mpdir" ¤; then;
  echo "Work directory $mpdir will be created.";
  umask 077 ;
  mkdir -p -m 700 "$mpdir";
fi;
PATH=$PATH:/usr/sbin;
echo "Format the file system $dsn.";
zfsadm format -aggregate $dsn;
echo "Mount $dsn on $mpdir.";
mount -s nosetuid -t ZFS -f $dsn $mpdir;

There is no output in STDOUT or STDERR.

How can I see the output of the script to make sure it is actually running?

I would ask IBM, but this is running on z/OS v2.3, which is not supported, and 
they won't help.

Thanks

Gadi

Responding to my own post. It was SYNCSORT that required single extent SORTWK.
I remember needing to update an ACS routine to enforce this.

This is old, circa 2009, so the restriction may have been removed.

Also, I concur with the JCL recommendations. Allow the sort program to figure

Hello DFSort experts!

Where can I find the explanation of SORTWK space usage? I seem to recall 
reading that only the primary space is used on a SORTWK, so if I have //SORTWK  
DD SPACE=(CYL,(5000,2000))...
I will only get the primary space of 5000 cylinders, and the other
14x2000 cylinders is never used. Is that right?

Is there a written explanation I can forward to the programmers so they 
understand this?

Also (since I know it will come), is there any good way to calculate how much 
DASD sortwork would be used? I know this depends on what is in memory at the 
time, but want to get a better handle on how Sort determines what it needs.

Thanks, everyone! This might be a good discussion!

So is IBM definitely dropping support for the z13s BEFORE z/OS 3.1 is 
officially out?  If not, then it should be supported by z/OS 3.1, as well as 
products like z/OSMF (which are required in order to install z/OS) should be 
able to be run on the z13s, isn't that correct?

Obviously the 4341 and z/OS 2.5 (or z/OS at all) were not compatible, and the 
4341 was discontinued (hardware and software support) before z/OS was announced 
or made available.

In this case, the z13s is still supported by IBM, and is supported by z/OS.

I guess what I am looking for is an official statement that the z13s is not 
supported by z/OS 3.1.  All I currently see is that the z13s isn't listed on 
the installation list for z/OS 3.1, but as it's no longer marketed, that makes 
sense.  That doesn't mean that the z13s can't 'run" z/OS 3.1.

Can the z13s "run" z/OS 3.1?  All I need is a simple yes or no.  Or even a 
"maybe" depending on extended lifecycle support.

If it is 100% not going to run z/OS 3.1, then I would like to be able to tell 
the managers of the 5 sites that are running them that they will need to "move 
up" or "migrate off".  I can't do that without a definitive response.

I would tak  a couple of FICON cables and string them between ports. Not sure 
about the z/14 hardware design.

Can we use the back plain of the z/14 to do the CTC thing?

Not my dog, but I would not do that, except under extreme duress.

Even PDSE can be safely shared. If updates only occur from one LPAR and 
read-only everywhere else. And, said updates may not be reflected immediately 
(or until next IPL) in the other read-only LPARs

Yes, PDSE do require SYSPLEX. Not GRS-plex, not CA-MIM (or MII), but SYSPLEX.
Reason: PDSE use sysplex communication, not GRS facilities.

Regarding to the topic: in order to share datasets you need ...nothing.
No parallel sysplex
No base sysplex
Not even GRSplex
No SMSplex
Simply nothing except DASD available from several systems.
Of course, the more mentioned facilities you have the better sharing is.
And yes, in order to share PDSEs (properly) you still have sysplex.
However you can share ICF BCSes (catalogs), VSAM, PS, PDS, etc.
Note: there are various flavours of sharing. Shared DASD as a data transport 
method, shared PDSes with jobs, REXX tools, etc. - it can be shared easily, 
because it is not heavily used. Batch datasets - assuming proper batch windows 
it is also can be shared easily.
For frequent sharing it is good to think about ICF ECS or RLS, etc.
