Re: Curious about IBM time conversion example program

[Bill Godfrey]

The number of seconds per TOD unit is too large to be represented in a signed 
fullword, but half the number of seconds is not too large.
So they break the computation into 2 divides.

When the STCK value is hex ba9a048bca00 (January 10 2004 13:37:05) or 
larger, the value after subtracting EPOCJ70 is hex 3D09, and a 
fixed-point divide exception occurs on the divide instruction. This is when the 
Unix time rolled over to hex 4000.

Since dividing by hex 7a12 (decimal 204800) and then by 2 is the same 
as dividing by 4096 and then by 1 million, one way to avoid the divide 
exception is to replace the 4 instructions with these two:

SRDL  R14,12   DIVIDE BY 4096
D R14,=F'100'

Enterprise COBOL V6.2

[Frank Swarbrick]

https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?subtype=ca=an=897=ENUS217-323

- Compiler support for the new z14 hardware and z/OS V2.3 operating system so 
applications can take advantage of the latest IBM Z architecture and operating 
system features and capabilities
- Exploitation of the new Vector Packed Decimal Facility of z14 to increase the 
performance of decimal compute intensive applications without the need for 
source code changes
- Implementation of the new JSON PARSE statement to provide you with additional 
programming and modernization features
- Addition of the COBOL 2002/2014 Conditional Compilation language feature
- New and changed COBOL statements for increased functionality
- New and changed COBOL options for increased flexibility
- Improved usability of the compiler in the z/OS UNIX System Services 
environment
- Improved interfaces to other licensed programs and tools
- Improved listing layout so that compiler diagnostic messages are easier to 
find
- Compile-time improvements (with OPTIMIZE(1) & OPTIMIZE(2)) and runtime 
performance enhancements


Nothing mindblowing.  Conditional complication seems nice.


Vector Packed Decimal Facility sounds interesting.

"The Vector Packed Decimal Facility allows the dominant COBOL data types, 
packed and zoned decimal, to be handled in wide 16-byte vector registers 
instead of in memory. Decimal and floating-point computationally intensive 
COBOL programs, which are optimized with Enterprise COBOL V6.2 and that target 
z14 ARCH(12), can deliver CPU time reduction on the z14 server over the same 
applications built with COBOL V6.1. No source changes are required to take 
advantage of this new facility; just recompile with ARCH(12) to target z14."


And here's a "big one":  "Compiler diagnostic messages now appear at the end of 
the listing, as was the case in COBOL compilers before Enterprise COBOL V5."  
!! :-)

I still long for implementation of some of the more interesting/useful features 
of COBOL 2002 and COBOL 2014.  But at least they are doing something.

Oh I get it now - Unix epoch second times are 32 bit *signed* integers.
So, they are doing SLR 14,14 prior to dividing by two to truncate at a
(signed) 31-bit integer.

0x7FFF is Jan 19, 2038 (UTC), the latest time that can be represented
as a 32-bit signed integer seconds.

In Silicon Valley, dropping in at the GooglePlex, tech museums and the 
Jobs garage


By Renee Sklarew

Like my college-age daughters, I am in love with my iPhone. And my ardor 
increased while I was researching a guidebook. With my cellphone, I 
narrated each hike into the Notes app, used Google Maps when I got lost 
and the Camera app to capture scenery. As I worked, I wondered how we 
got from room-size mainframes to this portable computer-in-my-hand.


So when Southwest Airlines started offering daily nonstops from 
Baltimore-Washington International Marshall Airport to San Jose, I 
booked a trip with my husband, Eric. After an affordable 
transcontinental flight, we landed at Mineta San Jose International 
Airport, in the heart of Silicon Valley.


Without a personal invitation from an employee, you can’t enter the 
offices of Apple, Facebook or Google, but you can visit each campus on 
your own. We like taking tours, so we reserved with a company that 
provides personalized ones and explains how Silicon Valley came to be.

First time I saw a technology I'd used -- Silent 700 terminal, I think! 
-- exhibited in a museum, I had definitely mixed feelings. Plenty more 
of our history is now on display as artifacts. Someday they might have a 
stuffed baby boomer system programmer on display.

Dear ibm-mainers,

https://www.ibm.com/support/knowledgecenter/SSLTBW_1.13.0/com.ibm.zos.r13.bpxb500/bpxzb5c076.htm

This bit:

SLR   R14,R14
LAR1,2
DRR14,R1


I'm curious about something - the EPOCST value they use is actually one half of
the number of seconds per TOD unit.   And so they divide by two.
At first I thought that they were attempting some kind of rounding to the
nearest second, but I don't see how this accomplishes that (or if rounding
would even be desirable).

TSO Relogon Buffer and the ECT

Hi Folks,

   As a result of the recent discussion about finding the TSO ECT 
control block, and because of the fact that the ECT address can be found 
after the end of the TSO Relogon Buffer (pointed to by PSCBRLGB), we 
came up with a set of programs to display and manipulate the TSO Relogon 
Buffer.


   These can be found on the Updates page of www.cbttape.org, File 958.

   Use them safely, and in good health.

   All the best of everything to all of you.

Ok, so they've added protection against programs that do their own I/O. So that

Re: IBM z14

[Greg Boyd]

It depends on the application.  If you are using IEBGENER to copy DSNA (clear 
text) to DSNB, and DSNB is flagged as requiring encryption  and key label KEYB 
is associated with DSNB, then you must have write access to DSNB and read 
access to KEYB.  IEBGENER will complete successfully if you have both.  But if 
your RACF admin forgot to give you access to KEYB, then the operation will fail.

Once DSNB is created (ciphertext), if an application issues a read, using 
standard I/O protocols, against the data set, then that app will need read 
access to DSNB and to key label KEYB before it can read the data in the clear.  
Without key access, the operation will fail.

Now suppost that your storage admin wants to backup/dump DSNB using DFSMSdss, 
which is not using standard application Read/Write protocols, but preforming 
the I/O at the track or cylinder level.  He will have read authority at the 
track or cylinder level, probably from a STGADMIN profile, but he won't have 
access to the key material.  And that's ok, because DFSMSdss will simply read 
the ciphertext as input and write that same ciphertext as output.

IBM has modified the I/O interfaces to require the appropriate access to both 
data set and key when data will be processed in the clear, and only to require 
data set access when the ciphertext will be preserved.

​We have such contracts (old) with Compuware and BMC. We are still on a
z9BC with z/OS 1.12. Until about 2 months ago, this made complete sense
because the company had decided to "cloud-source" most of our processing.
That was recently cancelled due to "problems" with the vendor (unnamed) not
"getting it right" in all this time. Which resulted in increasing customer
complaints. First to us, then to various state "Board of Insurance"
department. That put a stick in a soft spot and got high level attention
fast. So now we are trying to undo the work of 2 years in a few months (by
Oct 1). But that costs money (increasing MSUs). And we are still desiring
"cost containment".  Things would be a bit less uncertain if the U.S.
Congress would just "do something" on healthcare - even if it is saying the
ACA is being kept as is. Can't plan a business when the rules might be
changed next week.

I don't directly support the product, but work with putting automation around 
it, so I don't know details or scope of how modified it is.
My impression is that it's not heavily modified. I don't necessarily look 
forward to conversion, but if there is (eventually) no choice...

Exactly, there needs to be an on-ramp that starts at zero (or very nearly so). 
Specifically for z/OS. (Does Linux for Z survive without z/OS cash to help back 
new machine development?)

I know it happens on occasion, but "on occasion"  doesn't seem like a long-term 
survival (let alone growth) strategy. It's too easy to get started on other 
platforms. Which also have way more mind share among the smaller/startup 
organizations.

Re: SMFLIMxx sample?

[Vernooij, Kees (ITOPT1) - KLM]

Hello Steve,

Thanks for your extensive answers.

Yes, this doc was already pointed to in a previous answer in this thread.

I think I can replace IEFUSI region control with SMFLIMxx, but I have some 
points of doubt.

You say: "Note that SMFLIMxx REGIONBELOW/REGIONABOVE are *not* related to the 
IEFUSI's "region size" parameter"
Am I correct to state that SMFLIMxx REGIONBELOW/REGIONABOVE are equal to IEFUSI 
setting a Regionsize=Regionlimit both below and above?
IEFUSI doc explains the value of difference between regionsize and regionlimit 
with regard to VL Getmains. Is this no important anymore, because SMFLIMxx does 
not provide control of a different regionlimit anymore?

Region=0M implies Memlimit=0M. Does the SMFLIMxx Memlimit parameter overrule 
Memlimit=0M for Region=0M tasks?
If so, a filter on REGION= would be helpful or I need IEFUSI to ignore SMFLIMxx 
for Region=0M steps.

Does NOHONORIEFUSIREGION in SCHEDxx also apply to SMFLIMxx, i.o.w. is SMFLIMxx 
also ignored like IEFUSI is? If so, will SCHEDxx docs be updated?

Thanks,
Kees.

RMF 3 does not find modified user panel ERB3USR.

[Peter Hunkeler]

I'm trying to implement an RMF 3 user report. I defined everything using the 
RMF 3 Utility, then modified the RMF 3 user report panel RMF3USR, and save this 
into my personal ISPF panel library.

I'm LIBDEFing those libraries before starting RMF. However, it seems that 
program RMF is making its own allocation to DD names ERBPLIB, ERBMLIB, ERB0TABL 
and ERB0TLIB. For this reason, it cant find the modified ERB3USR panel and 
always uses the installation version.

I could not find what I'm missing. Searching the manuals for ERBPLIB gives no 
results.

Has anyone done this? Any hint?

How challenging were his data?  In the easiest case, no "phrase" and
