There is something wrong with the link or with your server.
This is n-th time I'm trying to download the documentation and
*everytime* it starts with good speed i.e. 2MB/s, but soon the speed is
reduced to 20-50kB/s.
I checked it several times. It is not a problem with my link - I have no
problems with other sites, including some other IBM ones. The problem
regards documentation file only.

Re: z/TPF questions

[Parwez Hamid]

Others have already covered some of the points and there is more about the 
history of z/TPF here - (I won't repeat what's already mentioned Wikipedia):

https://en.wikipedia.org/wiki/Transaction_Processing_Facility
[https://upload.wikimedia.org/wikipedia/commons/thumb/5/51/IBM_logo.svg/1200px-IBM_logo.svg.png]<https://en.wikipedia.org/wiki/Transaction_Processing_Facility>
Transaction Processing Facility - 
Wikipedia<https://en.wikipedia.org/wiki/Transaction_Processing_Facility>
Transaction Processing Facility (TPF) is an IBM real-time operating system for 
mainframe computers descended from the IBM System/360 family, including zSeries 
and System z9. TPF delivers fast, high-volume, high-throughput transaction 
processing, handling large, continuous loads of essentially simple transactions 
across large, geographically dispersed networks.
en.wikipedia.org

The key points about TPF were very high availability (Tightly and Loosely 
Coupled systems - Parallel Sysplex came many years after 'TPF' in its various 
guises and used the same 'timing' technology used by TPF), very high 
transaction rates, very fast IPL - over a minute was too long, ability to share 
data records with the multi-path locking facility in the early IBM DASD 
sub-systems.

At the risk of starting more discussion/debate, some general points not covered 
by Wikipedia:

  1.  TPF workloads requiring very high I/O rates , there has always been an 
option to get more than the standard number of I/O processors (SAPs). I 
believe, with today's cycle time and capacity of processing units, this is less 
of a concern.
  2.  CPSIME was a 'mini' version of the Airlines Control Program (ACP) 
specially developed for small airlines and ran on DOS/VSE. It then transitioned 
to ALCS running on 'MSV' or z/OS, as we know it today
  3.  During the late 80's TPF sysprogs and application developers (mainly 
assembler) were in very high demand and some managed to get eye-watering 
salaries 🙂. This was basically due to lack of skills and the high demand for 
these were driven by the new players in the Global Distribution Systems (GDS. 
to you and me, commonly known as reservation systems). The key players at that 
time were Amadeus, Galileo and a large European railway company.
  4.  Over time, due to consolidations etc. the number of TPF sites have not 
increased and a lot of airlines have 'outsourced' their reservation and 
departure control systems to the major GDSes. Some of the 'fares' component has 
been off loaded to alternative platforms.
  5.  With the concept of 'good enough' computing, high availability and 
'sub-second' response times with associated costs are not attractive to today's 
budget airlines who are using other platforms for reservations.

Subject: z/TPF questions

I know the IBM-MAIN forum is mostly about z/OS, but I wanted to ask
about about z/TPF - it seems to be on topic.

z/TPF

TPF is the system I have never seen.
I'm pretty sure there is no TPF installation in Poland.
However I'm curious about the following:
1. What is typical size of TPF system? I mean MIPS sizing. Is it huge or
rather small?
2. Does TPF typically run in bare LPAR or it is usually run under z/VM,
like z/VSE is?
3. What is the pricing of TPF?
3.1 Is it just single price per system, I mean no paid optional features
like in z/OS?
3.2 Is it expensive? I heard, it is much more expensive, when compared
to z/OS running on the same MIPS base.
4. Any special settings in LPAR definitions? I remember about specia
LPAR mode - ESA/TPF or so. However I don't know any explanation of the
difference.
5. Does it use regular CP's only? Or maybe there are some workloads
applicable to zIIP or even other processors?
6. Does it use SAP processors more extensively than other OSes? I heard
about it.
7. Does exist any z/TPF forum like IBM-MAIN?
8. What are known customers? I'm not asking about company secrets, but I
know (knowledge publicly available) about Citi, Marriott, VISA, BofA,
American Airlines, BA, Sabre, Amadeus and some more. Any other known
notable customers? Banks? ATMs? Reservations? Hotels? Anything else?

Any clue will be appreciated. I have to secret plan, I just want to
learn about it. Just curiosity.

Re: ILR012W ALL LOCAL PAGING SPACE IS FULL OR BAD, ASM WAIT03C RSN=01 [EXTERNAL]

Flash Express features (PCIe cards with flash memory installed in the PCIe I/O 
Drawer) were replaced with Virtual Flash Memory features on the z15. 
Physically, VFM is just part of the installed memory DIMMs and 'fenced' from 
the main memory. If VFM is ordered, overall main memory available is reduced.

On the z13 and z14 generations it was called Flash Express and connected using

Re: z13s to z15 Mainframe

[Parwez Hamid]

There isn't a 'valid' upgrade path from a z13s to z15 T01 or T02 (BTW: there 
isn't one from z15 T01 to T02 either!!). However, there may be 'other' options. 
Remember, an 'upgrade' normally means keeping the same serial number. This may 
be necessary for legal/financial reasons.

Other options (if available, migration offering i.e. z13s to z14 ZR1 to z15 
T01) may be possible. Best talk to your IBM or BP salesperson.

Agreed. The full name is OSA-Express Integrated Console Controller and was

Excuse me, but IMHO OSA-ICC is just way to get rid off old equipment
like 3174L. It is NOT replacement, it is only for local (called non-SNA)
terminals, printers and ...CONSOLES. Consoles are the most important. Of
course 3172, 3274, and other controllers were not the goal.

IBM went looong way from 3174s to to ICC. There were 2074 (quite
expensive), VTAM consoles (not very usable for IPL), older SYSCON
(Operating System Messages on HMC) and the latest 3270-like SYSG aka
PCOMM-like icon in HMC. SYSG is AFAIK z/VM nomenclature.


BTW, Note, nomenclaure for "HMC-like" consoles:
1. Operating System Messages
z/VM: SYSC
z/OS: SYSCON

2. HMC Integrated 3270 console (is it proper name?)
z/VM: SYSG
z/OS: HMCS

I don't know about other OSes.

Re: z114 retroactive height reduction (FC 9975) for transportation

[Parwez Hamid]

Short answer - YES.

FC 9975 is basically to reduce the 'height' for shipping/delivery purposes i.e 
if there isn't enough height clearance for the doorway. If a system is ordered 
with this feature, it just enlongates the install time. Nothing to stop 'you' 
to remove and reinstall the top bit. Just be careful with the cabling etc.

Subject: z114 retroactive height reduction (FC 9975) for transportation

Hi,

A bit of a niche question maybe, but this list usually enjoys those!

I need to move my z114, and sadly I don't have the possibility of
inspecting it physically right now. I was wondering if anyone knows if it
is possible to reduce the height of the z114?
In the IMPP there is a FC 9975 which separates the top portion in the
installation, but I have no idea if my individual has that feature.
Looking at older pictures of the frame there appears to be a "cut" between
the BPA and where the battery is supposed to be, so it looks like maybe
removing the side panels, the door, and then one might be able to detach
the top - but that's hard to say for sure on the pictures.

Does anyone have any experience removing the top portion for
transportation of a z114? Or similar experiences?

Thanks,

Re: An older device query - still using??

[Parwez Hamid]

The 3540 was a BUS & TAG attached device. I am not saying that its still in use

using strange BUS and TAG devices with channel convertors etc.

Excuse me, what is IBM 3540?
This is mainframe forum so I checked all historical DASD, including drum
device and 2305 (which is not a drum) and found no such device. I also
reviewed disks for small systems (S3 System 32, System 34... AS/400) and
still no such device. Finally I found ~500MB SCSI attached 3,5" disk
with such number.
However I still don't know what is 3540. Any clue?


Update: I found it. It is diskette (yes, 8" floppy diskette drive).
Where can I find the reference about it? In new shining z/OS 2.4 JCL
Reference!

Wow!


So, I dare to ask about this "still supported" device:
Was it Bus & Tag attached?
What parameters has the diskette? capacity, cylinders #, track length...
How it was recognized by operating system? Was it another DASD volume?
Every diskette was separate volume as tape cart?

IBM Announces the IBM z15 Model T02

[Parwez Hamid]

The z15 Model T02 is the new 'mid-range' Z System:


65 client configurable cores, an increase of 35 over the z14 ZR1, with single 
processor capacity of z15 T02 for equal n-way at common client configurations, 
approximately 14% greater than on z14 ZR1 with some variation based on workload 
and configuration.

15 % z/OS and 120 % Linux maximum system capacity growth over z14 ZR1 for 
exceptional scale in a single footprint.

More on-chip cache per core, compared to z14 ZR1, to help minimize memory wait 
times for data serving applications.

Up to 16 terabytes (TB) of available Redundant Array of Independent Memory 
(RAIM) real memory per server to help simplify capacity planning, enlarge 
in-memory buffer pools, cache sysplex shared data and controls in Coupling 
Facilities, and ease deploying memory-intensive workloads.

IBM Integrated Accelerator for z Enterprise Data Compression, designed to 
reduce the cost of storing, transporting, and processing data without changing 
applications. It replaces the zEDC Express card on z14 ZR1 and older 
generations of IBM servers, and interoperates compatibly with the zEDC 
compression used on previous IBM Z platforms and with industry-standard 
compression used on other platforms. Improved compression ratio (using Huffman 
coding) and order-preserving compression result in fewer CPU cycles to enable 
further compression of data, improving memory, transfer, and disk efficiency.

More than 30 new instructions codesigned and exploited by Java, new vector 
enhancements to improve analytics applications, and new instructions for sort 
acceleration.

Hello

Apologies for this question as am not a project manager.

My manager generally wants to know what are the phases of the project(for
example if someone is rolling out z15).

Could someone share the phases that you go through generally for a
Mainframe hardware implementation.

Re: z15 System Recover Boost

[Parwez Hamid]

Although I have no personal expereince, a couple of points you should be aware 
of:


  1.  You also need a couple of H/W feature codes 9930 and 6802 (to use zIIPs 
for SRB)for the z15 for use of SRB. FC 9930 for a contract to use this function.
  2.  You can use SRB for sub-capacity CPs and if using zIIPs for this function 
then you will need FC 9930.

If not done already, I also recommend you have a quick read of this 10 page 
'redpiece'.

Add to this the H/W and CFCC levels of the different systems. While the

IBM normally tests up to n-2 levels/generations of OS and H/W. Combination of

Re: Water-cooled 360s?

[Parwez Hamid]

The various high numbered Models of the 360 range had a chequered history and 
its bit difficult to know when these were announced (I am sure the answers are 
somewhere in Google) . Some were not 'announced' and were just built specially 
for NASA and 'others' and sold in very small numbers!

Its interesting IBM's own Archives for Mainframes doesn't even list the 360/85.

https://www.ibm.com/ibm/history/exhibits/mainframe/mainframe_profiles.html

BTW: During the very early 70's, I had the privilege of working on a 360/195 at 
Rutherford Labs in the UK (sister organisation of CERN). It was either the 
first  or second one in EMEA. The others were at The UK Met Office and 2 at VW 
in Germany.

The 360/91 was water cooled.  On power up with high humidity care had to be 
taken to avoid condensation/rain in the CPU.

I'd suspect that the 360/75 was water cooled but appears to be air cooled:

Re: Water-cooled 360s?

The first 360 water cooled system was Model 85 followed by the various 
'variants' of Model 91 (including the 195)

The 360/91 was water cooled.  On power up with high humidity care had to be 
taken to avoid condensation/rain in the CPU.

I'd suspect that the 360/75 was water cooled but appears to be air cooled:

Re: OOCoD experiences?

[Parwez Hamid]

Have you actually asked IBM how they can help meet your out of country DR 
requirements?

The CoD offering has been around since the G3 Servers. Started life as EBU 
(Emergency Backup), later became CBU and got further enhanced with CIU. CPE etc 
etc. All these changes/evolution were driven by customer requirements. So if 
the current offerings don't meet your requirements, no harm in asking IBM.

Understand that. But IBM should recognize that some organisations might
want an out of region DR site and not want to buy a mainframe with half
their production MIPS that's hardly ever going to be used. CBU is fine in
country but for some reason but outside country.

After all their DS8K Copy Services Manager provides replication support

Re: OOCoD experiences?

Peter,

2 points:


  1.  The way Speed Recovery Boost (SRB) or Instant Recovery (IR) was 
'announced' and not explained in detail, I wanted to make sure folks didn't get 
the impression that somehow the element of 'speed' was achived by giving a 
'boost' to the cycle time. As you rightly point out it has nothing to do with 
the cycle time. As we all well know or should know that sub-capacity and full 
capacity CPs have the same cycle time:-)
  2.  As regading the use of the word 'speed', you have pointed to one element 
of it and I pointed out the other one.
 *   As you state the 'speed', is going from sub-capacity to full capacity 
CP
 *   My point about 'speed' is that with the additional capacity provided 
by SRB i.e either by sub-capacity to full capacity CPs or CP workoad being 
dispatched to zIIPs will help bring up/down the OS and sub-systems quicker in 
the LPAR which gets SRB.

PS: It hasn't helped when some documentation states SRB or IR and some of the 
announcement material wasn't really very clear what was meant by 'speed' 🙂

If you are referring to the "speed boost", that is not correct. The
"speed" within "speed boost" does not refer to the speed of bringing
down/up anything. It does not refer to activating additional capacity
(such activation is part of the "zIIP boost" AKA the "zIIP capacity
boost"). It does not refer to (and does not have anything to do with) the
cycle frequency, which you may think of as the GHz of the processor.  It
refers to the effective speed of the processor by moving it from
sub-capacity to full capacity for the duration of the boost.

The fact that the cycle frequency of the machine does not change to
accomplish the speed boost is a reason that the boost is not called
"frequency boost".

Re: OOCoD experiences?

[Parwez Hamid]

The reason for the CBU capability to upgrade to any capacity with the limits of 
the physical installed capacity is to enable customers to 'CBU' multiple 
systems e.g. Customer might have 3 systems and only one DR system. As long as 
the DR system has sufficient capacity, they have the possibility of bringing up 
all LPARs on the 3 systems. Normally when customers plan for DR they tend to do 
so for critical and important business workload. Sys progs sandpits and test 
systems tend to get the chop. Again it all depends on the 'nature' of the 
disaster at the primary DC.

On/Off CoD is generally meant to cater for 'peak' or unexpected workloads e.g. 
month/qtr/year end processing or even sales on a Black Friday :-0 Hence the 
limit of 2 times of the purchased capacity.

Not an easy read by any means and it seems the 72 hours limit on CPE won't
work for our environment.

So the only option appears to be OOCoD.

Interesting for CBU you can upgrade from a base machine to any model so
long as it does not require adding more hardware but for OOCoD you can only
go up 100%

Re: OOCoD experiences?

[Parwez Hamid]

Adding my 2 cents worth:

Within the Capcity on Demand (CoD) offering for Z, there are a number of 
options available for different types of situations. Some have already been 
mentioned. A couple of useful docs:

  1.  IBM Redbook. Capacity on Demand SG24-7504. Almost 10 years old. Apart 
from some 'enhancements' to the offering (mainly to do with pricing/maintenance 
charges and entitlement to carry foward 'options' when upgrading to a newer Z 
system) and adding of the System Recovery Boost (SRB) option for the z15, the 
main content is still relevant.
  2.  zSystem Capacity On Demand User’s Guide  -  SC28-6943

All the CoD options i.e. CBU, CIU, CPE, On/Off CoD and SRB have T&Cs. Key point 
about the contracts is that some may be localised for an individual country. In 
addition, different CoD records have different time limits/expiration dates.

Some additional points:

  1.  Its a given that to activate the additional capacity, the physical 
resource is already available in the system.
  2.  CPE has been mentioned. CPE is temporary access to capacity intended to 
replace capacity lost within the enterprise due to a planned event such as a 
facility upgrade or system relocation. CPE is similar to CBU in that it is 
intended to replace lost capacity; however, it differs in its scope and intent. 
Where CBU addresses disaster recovery scenarios that can take up to three 
months to remedy, CPE is intended for short-duration events lasting up to three 
days, maximum.
  3.  On/Off CoD. On/Off CoD is available for up to twice the ‘purchased’ 
capacity of a given machine.  On/Off CoD upgrades are allowed for any processor 
configuration, up to the limit, as long as the number or capacity level of the 
processors is increased.  Upgrades that decrease the number or the capacity 
level of processors is not allowed.

In his response below, Tim mentions Instant Recovery. This is the same as 
System Recovery Boost (SRB). A few poinst about this option:

  1.  The name can be bit mis-leading. The 'instant' applies to the capability 
of ACTIVATING additional CAPACITY during/after an IPL - planned or unplanned..
  2.  This is limited to a short duration i.e. minutes/hours rather than days!
  3.  Some the documentation states 'speed'. Remember, this refers to the 
'speed' of bringing down/up of the OS and sub-systems. This is done by 
ACTIVATING ADDITIONAL capacity and not by changing the GHz of the processor.

First of all, what you describe was never true, not the way you describe it
anyway.

1. Sub-capacity Monthly License Charge (MLC) IBM software was/is based on
the monthly peak *four* hour rolling average (4HRA). A *one hour* OOCoD
activation is not four hours, so it was/is mathematically impossible for
your MLC to report a 4HRA equal to or even particularly near the total MSU
capacity inclusive of the one hour OOCoD activation.

2. "One-Time Charge" (OTC) IBM software, a.k.a. IPLA software, allows daily
OOCoD pricing -- "per MSU day."

3. You were/are also allowed to set softcapping on machines across OOCoD
activation(s), and with some potential "white space" (free) capacity
utilization. Sub-capacity reports will never report above the softcap(s).

Yes, that's right. With Tailored Fit Pricing peak MSUs (4HRA or otherwise)
no longer matter as such.

There's also now Instant Recovery on IBM z15 machines, with z/OS System
Recovery Boost. There is no software reported capacity associated with
legal/valid z/OS System Recovery Boost(s).

Does your workload qualify for Capacity for Planned Events (CPE), and are
CPE's T&C compatible with cross-border requirements?

Re: I saw 7 new college mainframe hires!

[Parwez Hamid]

I hope this is growing trend and continues elsewhere. Last week there were at 
least 25 of these young ones at the UK Guide Share Conference. They had there 
own '101' track. A number of sessions were actually presented by those who have 
been working with IBM Z for a couple of years!

If this continues at this rate, I will need to continue attending just to bring 
the average age up:-)

You will be better off if you stop digging into documentation and speculating 
about CBP. It may have been a twinkle in someones eye within IBM and some work 
may have been done before it was canned but code/documentation slipped through

Re: IBM z15 Announcement

[Parwez Hamid]

Re: I may be wrong, but I understand the news about HMC as pizza-box PC
server inside CEC's rack.

Yes, you are wrong. The new optional IBM Hardware Management
Appliance (FC 0100) with the z15, eliminates the need for a standalone Hardware 
Management Console. Both Hardware Management Console appliance and Support 
Element Appliance run virtualized on the Support Element hardware servers 
integrated with thez15 CPC

On z15, the HMC can be a stand-alone 'PC' (mini-tower or rack mounted), or  can 
run (as Hardware Management Appliance) on the Support Elements hardware (1U 
rack mounted servers integrated in z15 A frame).

Note:The Hardware Management Appliance (HMC application) is accessible via a 
remote web browser (thus there is no change in user experience for HMC 
interaction) and can manage N-2 generations systems (z15, z14 ZR1, z14, z13s 
and z13).

Additional details of new HMC functions in the Redbook.

server inside CEC's rack.
Rack-mounted HMC is nothing new, but z14 does not allow to put HMC
inside the CEC, despite SE's are pizza-boxes inside.

What's more interesting: changes in HMC-SE functionality. The goal is to
make Single Object Operations unnecessary, in other words all user
activities available from HMC panels directly.

Re: Blank fanout z114 CPC adapter

[Parwez Hamid]

Slide 8 shows the fanouts for a z196 Book.

CPC Drawer fanouts for a z114 shown below. I think, once you remove the I/O 
Drawer (not a a cage 🙂) , unless you need the I/O drawer fanouts for a 
different type of fanout, you can just leave the I/O drawer HCA2-C fanouts. 
Shouldn't do any harm.

Unable to imbed a picture of the z114 CPC drawer. If you want one I can send it 
direct to your email.

Re: z13s with single CPU able to use SMT?

[Parwez Hamid]

SMT is only supported for zIIPs, IFLs and SAPs.

–z13(s) allows following engine types to run in SMT mode
•zIIPs under z/OS
•IFLs under z/VM

Subject: z13s with single CPU able to use SMT?

Hi,

one of our boxes is a z13s (a model N10 with a single CPU), and supposedly if 
you change LOADxx to add PROCVIEW CORE and add the IEAOPTxx entry of 
MT_CP_MODE=x, it will open up the use of the SMT thread.  If I code 
MT_CP_MODE=2, it gets an error that the value (2) is not within limits.

My "D M=CORE" command shows:

IEE174I 23.27.00 DISPLAY M 793
CORE STATUS: HD=Y   MT=2  MT_MODE: CP=1  zIIP=1
IDST   ID RANGE   VP  ISCM  CPU THREAD STATUS
   +   -0001  M   FE00  +N

CPC ND = 002965.N10.IBM.02.000CD497
CPC SI = 2965.A01.IBM.02.000CD497
 Model: N10
CPC ID = 00
CPC NAME = P00CD497
LP NAME = SBOX   LP ID =  3
CSS ID  = 0
MIF ID  = 3

whereas it used to (before this change) show:

D M=CORE
IEE174I 22.31.01 DISPLAY M 292
CORE STATUS: HD=Y   MT=1
IDST   ID RANGE   VP  ISCM  CPU THREAD STATUS
   +   -  M   FE00  +

CPC ND = 002965.N10.IBM.02.000CD497
CPC SI = 2965.A01.IBM.02.000CD497
 Model: N10
CPC ID = 00
CPC NAME = P00CD497
LP NAME = SBOX   LP ID =  3
CSS ID  = 0
MIF ID  = 3

So it changed MT=2 and appears to have a ID range changed from - to 
-0001, so does that mean I now have 2 threads even though the IEAOPTxx 
setting of MT_CP_MODE=2 fails?

How do I tell if I am actually getting the use of two threads instead of one, 
is there something in RMF that points to this?

Thanks in advance,

Brian

All Z systems have a certain amount of minimum memory for customer use in the

memory for the HSA - again included in the base configuration. If required, 
customers can purchase extra memory up to the maximum limit for the System.
 
z14 M/T 3906, Minimum = 256 GB, Standard HSA = 192 GB
z14 M/T 3907, Minimum = 64 GB, Standard HSA = 64 GB
z13 M/T 2964, Minimum = 64 GB, Standard HSA = 96 GB

Re: Quick Q - OSA and FICON

[Parwez Hamid]

Your Q has already been answered. For reference only, I will add one additional 
point:

Starting with the newer generation of FICON features i.e. FICON Express16S+ 
(introduced with the z14), like previous generation
of FICON features, both ports have its own PCHID and CHIPD. The keep difference 
is that both ports must be defined as FC or FCP.
With the prior generations both ports could be FC or FCP or a mix of FC/FCP.

I know when you are looking for a quick answer, reading the manual isn't very 
appealing. It has
already been suggested that IBM Redbooks can be an a very good source for 
information. I strongly recommend
you download and keep these handy. The key Redbooks I would recommend for Z are:

1)  Technical Guide (each generation of Z System has its own)
2)  The IBM Z Connectivity Handbook
3)  The IBM xxx Setup Configuration (xxx = the System you have/are interested 
in)

Of course, in addition there are lots of other Redbooks for Z, z/OS, Disk, 
Tapes etc

Re: Internal Coupling Channel on z13

[Parwez Hamid]

Others have already said this. With just a single CP on the system, its not a 
good idea to have a CFCC LPAR on the same CP which is also being used for z/OS 
LPARs.

If you have not already read the the doc at the link below, I suggest you do. 
It is very comprehensive and covers a lot more than you need.

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwiA3vqJlpXgAhXPc98KHdhGCv8QFjABegQIBxAC&url=https%3A%2F%2Fwww.ibm.com%2Fdownloads%2Fcas%2FJZB2E38Q&usg=AOvVaw3YAB90hstZWbpesUsL-IDn

If the link doesn't work, search for ZSW01971-USEN-26 on google. In addition to 
this doc, there are various Redbooks and of course Knowledge Center:-)

I know you are looking for possible use cases/recommendations for what you 
would like to do with a single CP system. I will be very surprised if anyone 
has such a configuration on a 'production' system.

Re: Dummy query on processor failover

[Parwez Hamid]

If I have understood your Q correctly, depending on your Z system 'model', 
apart from a few older 'BC' systems, all Z Systems have dedicated 'spare' 
PU/PUs (processing units). If any CP, IFL, ICF, zIIP or SAP fails, 'sparing' 
action will take place transparently and in your example the 'SPARE' PU will 
characterized as a CP. How quickly does this happen? You won't even notice it. 
There is a lot more to this. If for some reason there aren't any 'SPARE PUs' 
left, then one of the uncharactized PUs i.e. not purchase by the customer will 
be used by the 'sparing' action. In case of multiple 'PU' failures (CP, ICF, 
zIIP etc) , there is a pecking order as to which one will be 'recovered' first. 
This is documented in the Redbooks I co-authored. Sparing is transparent to the 
operating system and applications.

I believe it comes with it's own HMC function within the 16U space, but it uses

The z14 ZR1/LR1 has a KVM switch which permits the KMM to be switched between

Re: SSL/TLS MSU usage

[Parwez Hamid]

Mounif,

I am unable to comment on any 'increase' of the CP utilization. CPACF has been 
around for a very long time. Both the systems you mention have the CPACF 
function. You will need a no charge feature (not available for embargoed 
countries) for microcode to enable CPACF. The other key point to note is to 
check if CPACF will support all the en/decryption algorithms you want to use. 
If not supported by CPACF then you might need the Crypto Express feature for 
which there is a charge.

Parwez

BTW: I have just Googled for CPACF and Crypto Express performance etc. There 
are lots of hits (I haven't browsed the websites) on this subject including 
some SHARE presentations.

Re: IBF missing in new z hardware

[Parwez Hamid]

Jake,
If you don't have access to IBM TechDocs, I can send the PDF version to you 
direct. There are some important considerations if you are using the z14 ZR1 as 
a coupling facility. This is covered in detail in the Tech Doc.


Short answer. customer supplied UPS. 

Here is some text I have cut from the TechDoc I referenced:

The Internal Battery Feature (IBF) is an optional feature on many of the IBM Z 
family processors. The IBF provides a local uninterrupted power source
and further enhances the robustness of the power design present in the 
mainframe and increases a mainframe’s immunity to power line disturbance
. It provides battery backup power to preserve processor data during a loss of 
power on all power feeds from the computer room. The IBF can hold 
power briefly during a brownout, or for orderly shutdown if there is a longer 
outage. IBM announced the IBM z14 ZR1 in April 2018. The announcement included 
information about the single 19” frame that houses the ZR1hardware components 
as well as a new Feature Code (FC), FC 0617 – 16U Reserved, which allows 
customers to install components other than ZR1 hardware inside of the 19” rack 
given that it meets a set of criteria for the space. 
The ZR1 will not be available with an IBF; clients requiring a battery backup 
solution must consider an alternative battery backup solution when planning for 
the ZR1
. 
Although the IBF is offered on the dual frame z14, it will not be offered as a 
feature option for the IBM z14 Model ZR1 processor. Clients with sensitive data 
on a ZR1 will need to explore an external industry - standard solution such as 
an Uninterrupted Power Supply (UPS) to address concerns regarding back -
up generator lag - time.

IBM ZR1 Considerations. There is no IBF feature for any z14 Model ZR1 . Battery 
backup, such as an external UPS solution or floor wide UPS solution, can be 
used to provide power resiliency to the ZR1. A UPS installed into the 16U 
Reserved Area will only be able to provide battery backup to other 
hardware installed in this area; ZR1 hardware, outside of the 16U Reserved 
area, cannot be powered from a UPS installed in the 19” rack.

Battery backup power from an external UPS solution or floor wide UPS solution 
can provide the ZR1 power in case of a brownout, or in the case of a longer 
power outage, it will provide time to properly bring down components running in 
the ZR1. This can become particularly important when Coupling Facilities (CF) 
are housed inside of the CPC.

Re: Dummy question about CHPID

[Parwez Hamid]

Whether 'old' or 'new' OSA Express 1000BASE-T features, its always been the 
case i.e. one CHPID for 2 ports.

When it comes to 'FICON' features, there has been a change with the latest 
feature i.e. FICON Express16S+. See below.

For both OSA and FICON features, the 'old' ones had a different form factor. 
When the PCIe architecture was introduced. the form factor changed and the 
number ports were halved. All OSA/FICON and Crypto features with an 'S' are the 
'new' form factor. OSA Express4S and newer, FICON Express8S and newer have the 
newer form factor.

OSA Express4S 1000BASE-T and newer, 2 ports/one CHPID
OSA Express4S 1 GbE and newer, 2 ports/one CHPID. These features are either LX 
or SX.
OSA Express4S 10 GbE and newer, 1 port/one CHPID. These features are either LR 
or SR.

FICON Express8S and FICON Express16S, 2 ports/2 CHPIDs. Each Port can be either 
TYPE=FC or FCP or both can be TYPE=FC or FCP  
For the latest FICON Express16S+, 2 ports/2 CHPIDs. The main change here is 
that BOTH ports have to be either TYPE=FC or FCP. Can't have a 'mix' of TYPEs 
on the same physical card. 

In addition all FICON features are either LX or SX.

Assuming you are migrating to a z14 ZR1, comparing to the z114, there are a 
number of things you should be aware of to do with size of the system, power 
requirements, features NOT supported etc etc. As I can't attach any docs to

Re: Why are highly busy zIIPs worse than highly busy CPs?

[Parwez Hamid]

Re the comment: 

How prevalent are installations today where the CPs run at top speed, in other 
words at the same speed as zIIP engines? In other words, Is it that valid to 
assume equal speed processors?  Clearly guidelines for lower zIIP utilization 
matter more when there is a difference, as offloading any zIIP work to a slower 
CP would elongate processing and response time, even if there is no delay 
waiting for a processor.

For any given Z system, the 'speed' (GHz) is always the same for all types to 
(PUs) processing units (CPs, IFLs, zIIPs, ICFs, IFP and SAP). In case of CPs, 
these can be different 'sub capacity settings' All the rest are always full 
capacity setting. Speed is always the same.

Re: One last question on TAPELESS delivery

[Parwez Hamid]

If I have understood Tim's response correctly, he is suggesting 2 options:

1) Use the DVD drive on your HMC. In your previous comments you have indicated 
that this is almost impossible!!
2) Use any PC (your own desktop?) with a DVD drive which has access to z /OS 
LPAR. 

Provided you have the right access/authorisation, there is another option to 
access the HMC for the management of the Z system. This is via a browser from 
any desktop. Somehow I don't think your site will even think about this :-)

As far as I can see, option 2 above might be the one you.

Just a general point. If you are interested, the HMC/Support Element (SE) 
network configuration, access and security details can be found in the 
following IBM manuals: 

1) IBM Z Hardware Management Console Security: SC28-6987-00
2) IBM Z Integrating the Hardware Management Console’s Broadband Remote Support 
Facility into your Enterprise: SC28-6986-00
3) Hardware Management Console (HMC) Version 2.14.0

All the above can be obtained from IBM ResourseLink. Customers normally have 
access to this website. The manuals also have diagrams showing the different 
options for network connectivity including via a Corporate network.

Re: SYSPLEX distance

[Parwez Hamid]

Abstract: Asynchronous CF Lock Duplexing is a new enhancement to IBM’s parallel 
sysplex technology that was made generally available in October 2016. It is an 
alternative to the synchronous system managed duplexing of coupling facility 
(CF) lock structures that has been available for many years. The new 
Asynchronous CF Lock Duplexing feature was designed to be a viable alternative 
to synchronous system managed duplexing. The goal was to provide the benefits 
of lock duplexing without the high performance penalty. It eliminates the 
synchronous mirroring between the CFs to keep the primary and secondary 
structures in sync.

You talk about 'speeds'. Just to make sure there is no confusion between

you have is different CAPACITY SETTINGs e.g. 401 or 501 or 601 or 701 (for the 
high end systems) and A01 to Z01 (for the mid range systems)

6.4 ES/9000 Remote Console



   The ES/9000 remote console consists of a display, a keyboard, and a system
   unit.  The remote console can be used either of two ways:


   °   As a local-area-network (LAN-attached) remote console, which can be
   connected through an IBM Token-Ring adapter, OR


   °   As a switched communication-line-attached remote console, which can be
   anywhere that a synchronous data link control (SDLC) communication
   line exists.

 6.4.1 Requirements



   Note:  The following information refers to IBM products.  You may choose
   equivalent products in place of those made by IBM.



   Remote Console:  The recommended remote console is:


   &ballot. IBM PS/2 Model 55 SX (or higher), OR


   &ballot. IBM PS/55 Model 5551 T (or higher), if using a double-byte
   character set (DBCS)



   The remote console must have:


   °   1.44MB diskette drive
   °   4MB main memory minimum; 8MB for DBCS


   Note:  With 4MB of main memory, the DOS box may need to be disabled on
   your system to allow the remote console application to run.  IBM
   recommends 6MB of main memory to avoid this situation.
   °   40MB of hard disk space minimum
   °   10MB of additional hard disk space for each additional level of 9221
   licensed internal code that you intend to support
   °   15MB of additional hard disk space for second language support


   For more information on the remote console display, system unit, and
   keyboard, see the PS/2* or PS/55.  operating guide for the model you are

In the first instance, I would read the z14 Exception Letters on ResourceLink 
(every customer should have access) for any known issues rather than follow any

well know fact (I am sure you know this) that when attaching a new Z system to

Re: Potential stupid question - MSUs

[Parwez Hamid]

My 2 cents worth.

If you are fairly new to the MF world, you might find the concept of 'trust' a 
bit strange :-) At the risk of opening up a whole different discussion, having 
worked in the MF world for a very long time, my observations are that apart 
from a few 'rouge' vendors (I think most of this community know what I mean by 
this), majority did business on 'trust' basis. Many years ago, companies like 
IBM used to take a customers view. In a multi-CPC environment, if a customer 
stated that they used a certain product on X number of CPCs, that's what they 
were charged for. However some did 'break' the 'trust' and software audits told 
a different story. While some vendors may still be doing business on 'trust' 
basis others have taken steps to 'manage and audit' use of their software 
products by embedding checks in the product requiring 'keys' or expiry dates 
etc etc.

As I said, this is not the time for zBX education. Its history.

Re: Regarding IDAA, at the time zBX was first introduced (z196), there was 
ISAO - IBM Smart Analytics Optimizer. Then they changed name (only a 
name?), then IDAA arrived.
And not, IDAA is NOT an zBX example! It does not use any of zBX specific 
features. It's more like Dell/HP/AnyVendor LAN-attached appliance.

ISAO did use 'similar' H/W and connectivity as the zBX with System X Blades. 
IDAA was the follow-on solution using PureData System for Analytics
(Netezza Technology). Both SOLUTIONs were (ISAO)/are (IDAA) tightly integrated 
with System z, z/OS and deep integration with DB2 providing transparency to all 
applications. IDAA is not just a LAN-attached appliance.

High Level Summary for Garbage Collection:

Guarded Storage Facility (GSF)

Also known as less-pausing garbage collection, Guarded Storage Facility is a new
architecture introduced with z14 to enable enterprise scale Java applications 
to run without
periodic pause for garbage collection on larger heaps.

z/OS

GSF support allows an area of storage to be identified such that an Exit 
routine gets control if
a reference is made to that storage. GSF is managed by new instructions that 
define Guarded
Storage Controls and system code to maintain that control information across 
un-dispatch
and re-dispatch. Enabling a less-pausing approach improves Java garbage 
collection.
Function is provided on z14 running z/OS 2.2 and later with APAR OA51643 
installed.
MACHMIG statement in LOADxx of SYS1.PARMLIB provides ability to disable the 
function.
