Re: p-comm for dummies, please

[Timothy Sipples]

IBM documents the configuration steps pretty well, I think. You can find 
the documentation here (Personal Communication Version 14 assumed for 
these links):

https://www.ibm.com/docs/en/personal-communications/14.0?topic=layer-connecting-server-using-self-signed-certificate

https://www.ibm.com/docs/en/personal-communications/14.0?topic=certificate-using-management

https://www.ibm.com/docs/en/personal-communications/14.0?topic=ca-opening-key-database-adding-root-certificate

In short:

1. Provide the public self-signed root certificate in .ARM or .DER format 
to the user, preferably via a reasonably well secured transmission path. 
N.B. Not the private certificate!

2. The user adds the root certificate to the key database (
PCommClientKeyDb.kdb) using Certificate Management (Start → Programs → IBM 
Personal Communications → Utilities).

Alternatively you could obtain and deploy TLS server certificates that are 
signed by a well-known certificate authority that Personal Communications 
is already comfortable trusting.

Re: Why Would COPYSRVH Cause a 1M Page Demtion [Internal]

[Attila Fogarasi]

IARV64 pagefix will cause demotion if the area is not 1MB on a 1MB
boundary.  This was fixed in z/os 2.3 ... what release/ptf level are you

Re: Automation of CBU activation

[Steve Horein]

You would need to enable the ProcOps Tower to make ISQCCMD available on the
(ProcOps) Focal Point(s).
https://www.ibm.com/docs/en/z-system-automation/4.1.0?topic=cc-cbu

I have our IPL process automated solely with ProcOps, performing various
ISQSEND, ISQCCMD SYSRESET,  and ISQCCMD LOAD commands against the defined
target hardware. Automation of AOFA* response messages can assist with
ISQCCMD commands, and ISQ900I messages (from the System Console) can be
used to assist in processing before VTAM is available on the remote system.

There are some really good folks at https://groups.io/g/SAUsers that can
also provide pointers. The price to join is right, too!

Hi Lionel,

The only supported Linux distributions for zPDT are RHEL and Ubuntu. 
They will pry my OpenSUSE (which they used to support but pulled the 
plug, even though they support SLES on the mainframe, HELLO McFLY,

had to do a bare metal restore back to OpenSUSE.  If you try Ubuntu, I

Why Would COPYSRVH Cause a 1M Page Demtion [Internal]

[Crawford, Robert C.]

I've been trying to track down what's causing system 1M page demotions on our 
test system.  The component trace IBM gave me shows, in part:

SYS5  SGTDEM64  0063  12:44:53.270019  Demote 1M 64 bit page
 FUNC1... COPYSRVH  High Virtual Copy Service
 JOBN1... ZUMCCMG1 ASID1... 0215 PLOCKS.. 8800C001 CPU. 0006
 JOBN2... ZUMCCMG3 ASID2... 022D RLOCKS.. 8800C001 RLOCKDET 0800
 KEY. 0036 ADDR 035E1008 ALET 

The COPYSRVH function isn't well documented but, from I see, UNIX fork 
processing invokes it to copy memory to the new process.  This makes sense in 
that JOBN1 and JOBN3 are both USS processes.

Both LFAREA and SCM on this system are less than 1% used.  Why is z/OS demoting 
pages?

Thanks.

Go with IIP and IFA. SUP will do fine for IIP. Ignore ZCBP. The 
fields haven't changed. (I haven't seen a zAAP in a long time, though.)


Despite what such products as RMF have chosen to display (and likely has 
made its way into all sorts of places), "IIP" is not a valid term. The 
name/term is zIIP, and similarly it is zAAP not AAP. You're welcome to 
continue using the pre-release names of SUP for zIIP and IFA for zAAP 
because we had to code something (the real names were not made known to us 

until way too late to support only those names). We cannot compatibly get 
rid of them, so fields with those names will exist forever.

I'd suggest being consistent -- either use the names or the pre-release 
names but don't intermix.

Current processors do not support zAAP. I've forgotten which was the last 
machine that did.

Yes. I know how to do everything manually, but am looking at what it takes to 
automate the entire process *without* GDPS but with SA for z/OS 4.1/4.2, 
current HMC microcode levels, and BCPii (z/OS 2.3 as I type this, but z/OS 2.4

Non-GDPS

Other than GDPS, what would one use to drive the invocation of BCPii? I am

Re: p-comm for dummies, please

[Radoslaw Skorupka]

It depends on PCOMM version.
Older versions offered iKeyMan - a part of Global Security Kit. It is 
(was) java-based certificate repository. You had to add CA or other 
certificates there, otherwise PCOMM won't accept the certificate. PCOMM 
by design do not accept unknown certificates and there is no option 
"click OK to accept and keep as trusted".
Later PCOMM also supported Windows built-in certificate management, so 
you had a choice which way to choose.

Now I think there is no PCOMM private certificate management

BTW: current version is v14. AFAIK there were versions 14, 13, 12, 6, 5, 
4... - no versions between 6 and 12. 6 and 5 supported both ways, 4 
supported only private repository, but at the time (late 90's) Windows 
had no certificates repository.

Re: SMF 30 record

[Peter Relson]

Go with IIP and IFA. SUP will do fine for IIP. Ignore ZCBP. The 
fields haven't changed. (I haven't seen a zAAP in a long time, though.)


Despite what such products as RMF have chosen to display (and likely has 
made its way into all sorts of places), "IIP" is not a valid term. The 
name/term is zIIP, and similarly it is zAAP not AAP. You're welcome to 
continue using the pre-release names of SUP for zIIP and IFA for zAAP 
because we had to code something (the real names were not made known to us 
until way too late to support only those names). We cannot compatibly get 
rid of them, so fields with those names will exist forever.

I'd suggest being consistent -- either use the names or the pre-release 
names but don't intermix.

Current processors do not support zAAP. I've forgotten which was the last 
machine that did.

Re: IBM Zcloud - is it just outsourcing ?

[Seymour J Metz]

Yes, like any other outsourcing and time-sharing contract, you need to define 
your requirements before committing to it, and that includes license issues.  
It's your responsibility to include what you need in the contract, but I would 
be very surprised if IBM was unable to deal with 3rd party software.

One of my reasons for asking about zCloud here was that I have been asked (at 
second- or third-hand) whether an ISV product is “supported” on zCloud, so 
there is clearly a case to answer. At first sight, if zCloud just means 
transferring LPARs to an IBM-owned machine, the answer would be ‘yes’. But 
there may be reasons why it would not be ‘supported’ - e.g. for licensing 
reasons, because IBM do not have the expertise to manage it, because IBM prefer 
to replace it with one of their owns products, etc.

Another reason is that I found a reference to “zcloud environments” in IMS v13 
documentation in regards to what is now called “cloud provisioning” ie using 
z/OSMF and possibly Z Cloud Broker) to create and manage middleware 
environments “on demand” using templates etc provided by the middleware 
developers. I now think that this use of the term “zcloud” here (or terms such 
as “Z cloud”, Z/cloud” etc rather than “zCloud” ) may refer generically to 
cloud services on Z rather than the “Managed Extended Cloud Infrastructure as a 
Service(IaaS) for IBM Z (zCloud)” offering.

There is still a nagging doubt that some ISV products may be required to “play 
nicely” on zCloud, especially in environments where instead of transferring an 
LPAR to zCloud a new z/OS system is created just for development purposes so 
that modern development tools can be used. In that case there could be a 
requirement for middleware to co-operate in the automatic provisioning of test 
environments.

At the risk of being contacted by an IBM salesperson I have attempted to get in 
touch with a “zCloud” person for information.

Re: IBM Zcloud - is it just outsourcing ?

[Seymour J Metz]

I hope that you never go into farming. Livestock are expensive. Shooting a cow 
represents a significant loss.  The only time a farmer kills a sick cow is when 
it's too expensive for the veterinarian to cure her. Otherwise you only kill 
your livestock when they are too old to be worth their keep or when they are of 
an appropriate age to sell for meat.

So, in your analogy, what is the cow? Is it an instance of an image, or is it 
the assets that you have deployued in that instance? The former costs little to 
deploy, the latter may be the heart of your business. You may shoot a horse 
with a broken leg, but do you really want to throw away a broken IMS or TPF 
application?

Re: IBM Zcloud - is it just outsourcing ?

[Allan Staller]

Classification: Confidential

On the subject of rapid deployment,

With  few tweaks and exploitations of standard z/OS facilities, I can deploy a 
shared  IMS (or CICS, MQ,... ) subsystem in about the recycle time of the 
subsystem + 5 minutes).
I even have the capability of updating one LPAR without affecting others. It's 
all in the packaging. Z/OS. Z/OS itself uses a minor variation of the process.

Couple the above packaging with a "master image", and I don't need z/OS MF for 
software deployment.
TANSTAAFL. It does cost me some DASD, but that's the price I am willing to pay.

I don't see a partially blank name, the entire section looks like it 
hasn't been filled in. (The names are at the end of each section, so 
might look like it belongs with the next empty section if you are 
eyeballing a dump.)



2. In the SMF 92-11 it reports data on the individual files used.  It
reports the file as used, for example  ./write.c I expected it to say
/u/adcd/write.c. The data as is, is pretty useless, as I do not know which
write.c was used. Other records have /usr/lib/nls/msg/C/fsumrcat.cat as
expected (because that is what the program used)
This is unfortunate, but I think it reflects the information available 
at the point the record is written. Given filesystem links etc. it may 
not even be possible to be sure of the path used to open a file if a 
relative path is used. The inode number and device number is probably 
the true identifier of a file.


You can probably make reasonable guesses about a relative path by 
looking at directory read records from the same task.
