I'm not sure what you mean here by "sunset that box." IBM withdrew all z13s 
feature codes from marketing years ago. However, IBM continues to provide 
support, maintenance, and repair services for IBM z13s servers, and IBM 
continues to support the vast bulk of its z/OS software product portfolio on 
IBM z13s servers. (Although sometimes there are functions within otherwise 
supported products that require a higher model machine.) There's currently no 
announced End of Service date for IBM z13s machines AFAIK.

IBM offered z/OS 2.5 with the classic installation option to all z/OS 
licensees, including licensees with small capacity IBM z13s machines, at no 
additional charge. IBM urged all such customers to place any such orders before 
the end of January, 2022. Lots of customers did exactly that (including many 
reading this forum), and they either have z/OS 2.5 installed now or they have 
it sitting on the shelf, ready to install. z/OS 2.5 is the last release of z/OS 
that can run on IBM z13 generation machines.

z/OS 2.5 is currently orderable and installable with the z/OSMF-based 
installation on all machines compatible with z/OS 2.5. The z/OSMF-based 
installation steps may run longer on certain capacity models, but it's still 
installable. CBPDO-based installation is also still available.

Over the past several decades of history IBM has eventually dropped software 
support for older models. z/OS 2.5 doesn't run on IBM 4341 machines, for 
example. Sometimes a model drop occurs at a version or release boundary, 
occasionally not. In the newer "continuous delivery" style of software delivery 
the machine model drops between version/release boundaries are getting somewhat 
more common, industry-wide. But in this case IBM hasn't even dropped support 
for z/OS on IBM z13s machines, not yet. (z/OS 3.1 will.) All IBM did was drop 
one installation method in z/OS 2.5 and only for orders placed after January, 
2022. IBM gave advance notice it would. IBM offered delivery of z/OS 2.5 with 
that installation option to any licensee that cared to order it by January, 
2022, and at no additional charge.

The z/os http/http enablement toolkit is part of z/os bcp. it starts at ipl
(no explicit start i needed). I make intensive use of this product (both
the http and json parser parts) and it works very well.

Moving/Merging Zones Into A New CSI

[Ross Vaughn]

We are in the process of upgrading Db2v12 to Db2v13.  
I am looking for suggestions/best practice for moving additional Target & DLIB 
zones from our Db2v12 CSI to our new Db2v13 CSI.
 
To test this out I backed up and restored the new v13 CSI to a ‘test’ CSI…ran a 
ZONEEDIT and pointed my DDDEFs to test datasets etc.…Then
Ran ZONEEXPORTS for a TARGET & DLIB from my current v12 CSI
Ran ZONEEDITs to update those DDDEFs
Ran a GZONEMERGE to copy over the associated FMIDs to the GLOBAL zone for the 
product I’m moving using ‘CONTENT’ and ‘FORFMID’
 
Is this the best approach?  Am I missing anything?
 
 
 
Thanks,
Ross Vaughn

Thanks Neil!

There is also a Java API as well as the Windows software. The Java API 
allows you to write custom reports and run them on the mainframe or 
other platforms.


The Java API can also convert SMF data to JSON format, so you can use 
any of the JSON reporting tools for queries, charts etc.

SMF Real Time Interface

[Andrew Rowley]

I have created a Java interface to the z/OS SMF Real Time Interface, and 
I am looking for people interested to try it out.


As background, the SMF Real Time Interface works in SMF logstream mode 
and allows you to define SMF in memory resources to receive different 
combinations of SMF records. Access to the in memory resources is RACF 
protected, and does not require exits or authorized code.


The Java interface makes it very easy to connect, read and disconnect 
from the SMF in memory resources.


I have put some samples on Github to show how it can be used: 
https://github.com/BlackHillSoftware/easysmf-samples/tree/main/easysmf-rti


There are samples to show:

 * Simple usage: connect, read, disconnect
 * Send SMF records in binary format to another system via HTTP
 * Send type 30 job end information in JSON format to another system
   via HTTP
 * Send SMS text messages from the mainframe for job failures using the
   Twilio Java API.

These will hopefully give some ideas about how it might be used.

Re: SAS Replacement

[Scott Barry]

Also, do consider that there is now a U.S.-based SAS language compiler called 
Altair SLC, where some reputable references have indicated that the Altair z/OS 
SLC / WorkBench software can be as much as 60% less-costly for licensing -- 
also, for those who know about this SAS/WPS history, there is no longer any 
potential legal exposure for an Altair-licensed customer in the U. S.

I have personally accomplished SAS to WPS on z/OS (the predecessor to what's 
now/today Altair SLC) with great success, under budget, and with happy 
customer/users as well !!  As well, I can attest that the Altair technical 
support, R&D team are quite responsive and attentive for bug-fixes and 
continuing with new-function enhancements.  The vendor support site provides a 
utility to analyze your SAS programs to identify compatibility or otherwise.

Re: [EXTERNAL] SAS Replacement

[Pommier, Rex]

Are you looking at perchance a replacement to MXG in order to get away from the 
SAS licensing costs?  There was a SAS alternative called "world programming 
system" that was ostensibly a drop in replacement to SAS.  It got bought out by 
Altair in 2021.  I played with it probably 15 years ago and it was a CPU hog 
compared to SAS back then.  I have no doubt they've vastly improved its 
performance since then.  

I know nothing about it, but there's a product called Pivitor that might do 
what you're looking for.  They have either a free trial or a much pared down 
free version (I don't remember which).

Is there a USS-file compatible equivalent to the SUPERC OVSUM compare yet?

[Collinson, Shannon]

I think there was a USS tools&toys thing (fscp?) that'd compare the contents of 
two filesystems that I used to run when converting those from HFS to ZFS years 
ago, but the tools&toys page is gone now so I can't grab that to check.  Pretty 
sure it wouldn't work for what I want to do anyhow, which is to compare the 
files/directories/etc in two paths that could be in different locations in 
their filesystems.  Is there something else that says "this guy's missing, this 
one's new, the attributes (or better yet contents) of these are different" for 
USS?  I cobbled together this from something a coworker had that compared just 
directories-and made it compare the listings of those directories-but the 
output's a little ugly.  Do you have or know of anything better?
#!/bin/sh
# Change these variables:
NEWDIR="/my/new/path"
OLDDIR="/my/old/path"
#
# Leave these as-is unless you know what you're doing
FDOPT="-type d -xdev"
LSDIR="-exec ls -lAs {}"
TMPFILE1=/tmp/find1.out
TMPFILE2=/tmp/find2.out
TMPOUT=/tmp/compare.out
#
# Gather the new directory listing and stick in in TMPFILE1
echo "Starting directory " $NEWDIR > $TMPFILE1
PRDIR="-exec echo  Scanning ${NEWDIR}/ {}"
cd $NEWDIR
find . $FDOPT $PRDIR \; $LSDIR \; >> $TMPFILE1
#
# Gather the old directory listing and stick it in TMPFILE2
echo "Starting directory " $OLDDIR > $TMPFILE2
PRDIR="-exec echo  Scanning ${OLDDIR}/ {}"
cd $OLDDIR
find . $FDOPT $PRDIR \; $LSDIR \; >> $TMPFILE2
#
# compare the listing files and save it in TMPOUT:

# display the results:

Probably even from JC, as a program which actually creates a data set,
unlike IEFBR14 which doesn't create data sets even though many
programmers say it does so.

Yet, an extended argument to fopen() might be a palliative to
vertical-thinking C programmers who expect fopen() to suffice
to create a file.

I've used languages, including antique FORTRAN, which nave
no "open", much less ALLOCATE -- you just start reading or
writing.

Again, the assumption is that the pricing was adjusted so it was not more 
expensive.

200 MSU was just to pick a number. It probably should be higher. What is the 
speed of a desktop PC these days? I am guessing my 4 year old PC is around 
600-700 MSU equivalent? A Raspberry Pi about 40-60 MSU? And 4 or more cores 
makes a lot of problems go away.

It would be good if z/OS at the low end had kept up with the performance and 
price improvements in the rest of the industry.

Having a WTO depends on how many exit calls there are per second. 100  a

Depending on where your exit runs, and what state it is in, a system level
name token pair might be a good compromise.
On first use - allocate a name token, set use count = 0; do a STCK and add
10 minutes - and store it in name token.
on every other call

   - increment counter
   - If stck(now) > the stored STCK
  - calculate the time delta - and WTO out # seconds and count

The time between WTOs may be > 10 minutes  but it gives you a flavour of
the count.   You might lose the odd entry if two TSBs are trying to update

Or do the WTO every 1000 calls.

zDEC compression questions

[Kenneth Kripke]

Hello, 

 We are in the process of implementing zEDC compression for DFHSM on our
test system to more or less shake out issues. 

Questions have come up. 

1.  How to recover if there is a failure in deflation of a compressed
dataset.  We have a mixture of z/14 and z/15 processors.  
2.  For the z/15 processor, the footnote for the SMF 30 record indicates
that compression statistics are no longer recorded.  How do you measure
compression?  Is this also true for the SMF 14 and 15 records? 
3.  Regarding deflation, is there a noticeable performance/delay ?  

Any information would be greatly appreciated.  

Regards,

Tom, 

Sorry I wasn't clear.  These processes don't run simultaneously.  We run 2 
production LPARs and at times during our nightly batch cycle we have a process 
on one or the other LPARs that will consume an entire processor for a period of 
time - anywhere from 10 minutes to an hour or longer.  Watching my SDSF-like 
screen or monitor, I can see that a single TCB is consuming 100% (or close 
thereof) of one of the engines.

You are running several processes that each need more than 50% of a CP, and 
your CEC has two CPs?

How much CPU do these processes use?

Unfortunately that (pricing) train left the station a long time ago.  For 
whatever reason IBM chose to keep the mainframe a niche product with fantastic 
I/O capabilities but a high price tag, thus ensuring its gradual fade.

Again, the assumption is that the pricing was adjusted so it was not more 
expensive.

200 MSU was just to pick a number. It probably should be higher. What is the 
speed of a desktop PC these days? I am guessing my 4 year old PC is around 
600-700 MSU equivalent? A Raspberry Pi about 40-60 MSU? And 4 or more cores 
makes a lot of problems go away.

It would be good if z/OS at the low end had kept up with the performance and 
price improvements in the rest of the industry.
