Re: RSU maintenance strategy - Need expert suggestions

[ANIL KUMAR]

Hi All,

Thanks very much for your timely and quick response. Yes have proposed a
strategy to the customer and will be reviewed by early next year. I will
have some follow-up questions regarding the same and will post to get some
advise. Thanks again.

Converting programs to accommodate 8-character userids and prefixes

[Sam Golob]

Hi Folks,

    I'm commenting on Ed Gould's comments.  Thanks Ed.  Much obliged.

    I've used MVT in the old days, but I'm not an expert from then.  A 
few years ago, I was experimenting with the ACCOUNT command to create 
new userids in SYS1.UADS (on z/OS), and I noticed that the size of each 
member was dependent on the BLKSIZE of the SYS1.UADS dataset.  For 
example, if your SYS1.UADS had a block size of 800, each member could be 
only one block, and therefore it had to be limited to 10 records.  But 
when I blocked SYS1.UADS at 8000, each member was 100 records.


    In the old days, it was customary to block SYS1.UADS at 800 bytes.  
So those userid members, being only 10 records long, sometimes needed 
several members to accommodate the information from several accounts, or 
logon procedures, or passwords, connected with a single userid.  Hence 
the USERID0, USERID1, USERID2 members, etc.


    In any case, it was quite a restrictive system, and the 7-character 
limitation has lasted, in TSO, for a very long time.  Until now.


    Now, hundreds of programs have to be updated.  We are working on 
it.  If any of you has fixed something related to this (or NOT related 
to this), please send it to me for inclusion on the CBT Tape, in order 
to benefit everyone else. Thanks much  We appreciate all the 
help we can get.


    One way of getting around it is not to turn on the 8-character id 
support.  But people in IBM have told me that they want to eventually 
make 8-character id support the default, so we've got to get there 
sooner or later.


    All the best of everything to all of you...

Sincerely,   Sam

  RSM will free frames if available frames are in short supply. 
If you obtain a smaller amount, get it backed, and then release it, you 
may
be more likely to observe the frames being retained.

Re: DFSORT: RACFICE query - how to extract all commands containing some text value

[Sri h Kolusu]

>>> Bruce  My final JCL:-

Bruce,

I sent you a JCL offline which does all the reporting as well as uses 
symbols and the userids can be dynamically passed.  I don't have an input 
data that has all the events that you are looking for.

>>> Martin Packer : This, I think, could use some Symbols love.

I agree and I also removed the individual sorts for each event type  and 
generated the report using the traditional reporting feature SECTIONS 
along with symbols :)

>> Robert Hansel : Kolusu, I would not recommend the use of RACFRW. It was 
stabilized in 1992 and won't report on the use of newer command operands 
such as NOEXPIRE. Bruce is better off using ICETOOL.

Thank you. Since OP is only interested in few of the event types , I just 
passed it on to him.

>>Elardus : Careful, Sri will SORT you out... ;-D

Nooo. I am not a RACF expert, So I have to agree with Robert. You can try 
the JCL that I sent offline and see if that works

Sam,

Almost…..  in the beginning there was sys1.uads 7 character ID . Then if you 
wanted to have a special accounting info etc and there was only so much space 
(IIRC 800 bytes) if you needed multiple accounts and accounting info etc the ID 
was extended until (I think 800 bytes) then in order to allow additional 
accounting info etc another “id” was created so instead of pepper an extension 
(new member) was created called pepper1 and so on and so forth until pepper9 
so, if memory serves me everybody had a pepper0 then depending on accounting 
info etc the next “id” was pepper1 etc etc pepper9.

Its been a while so that first ID ended with hex zero then the second was 1 
(this part here I am iffy on) as we only had 1 or 2 that had the added 
character. I just don’t remember of it was hex 00 then hex 01 or if it was a 
character 1 then 2 etc,,

The unallocation can wait until RSM sees a need to put them onto the available 
frames queue. It may well be that such a frame will be reused upon a later 
GETMAIN, when VSM assigns the same virtual address, I would understand.

Yes, it is much different! In the case you describe, you will find the page is 
allocated in the VSMDATA report. With freemained frames, you not see anything 
in VSMDATA.


Ed confirmed what was my understanding, VSM knows nothing about freemained 
frames. All traces are gone once the storage is freemained (when the page is 
completely freemained).


Earlier this year, when chasing the S0CA problems in COBOL code, I saw 
successful access to some virtual addresses in the system trace but VSMDATA 
said that page is not getmained. I did not understand how this can be, back 
then. I didn't know about freemained frames, yet. Now I understand.


The RSMDATA REALFRAME report marks such freemained frames. Out of curiosity, 
I'd like to once see this in a dump. Hence my question how to create such a 
situation.

Converting programs to accommodate 8-character userids and prefixes

[Sam Golob]

Hi Folks, (I'm sorry that my previous post was sent incomplete--pressed 
the wrong key)


   As you probably know by now, z/OS 2.3 has introduced the possibility 
of having 8-character TSO userids and 8-character TSO prefixes.  These 
name fields were previously limited to 7 characters, ever since TSO came 
into existence.  (I think the reason for the limitation was that the 
SYS1.UADS members, representing the definition of TSO userids before 
RACF, ACF2, Top Secret etc. had to have a number at the end of them, 
e.g. IBMUSER0, IBMUSER1, etc.  So the id itself was limited to 7 
characters in length.)


   Many programs, especially TSO commands, look to find the TSO userid 
in the PSCBUSER field (7 characters long) of the PSCB control block 
(mapped by macro IKJPSCB).  Also, the TSO prefix for your session is 
usually found in the UPTPREFX field (also 7 characters) of the UPT 
control block (mapped by macro IKJUPT).


   General 8-character userid support, in z/OS 2.3 (and presumably 
above) is turned on or off by a switch.  It was explained to me, that 
the support is quite complicated, so the installation has to be able to 
decide whether to turn it on, or not.  The installation's control is in 
PARMLIB member IKJTSOxx, in the LOGON parameter: LOGON USERIDMAX(8) . 
The place where this switch is located, is +6 bytes off the beginning of 
the TSVT (TSO Vector Table) mapped by macro IKJTSVT.  The setting is 
x'00' for pre z/OS 2.3, x'07' for z/OS 2.3 with support OFF, and x'08' 
for z/OS 2.3 with support ON.


   With the switch on, and if you have defined an 8-character userid, 
then the PSCBUSER field and the UPTPREFX field cannot contain the userid 
or the prefix, since they are only 7 characters long. So there are 2 new 
fields, at 2 new locations in the PSCB and UPT control blocks, 
respectively.  The display below shows where they are.  Also, the length 
fields in the PSCB and UPT are both new, when you have an 8-character 
userid.


   The displays below will show the location and content of all the 
relevant fields.  They were produced by the LPSCB program (parameter U) 
from CBT File 300, and by the ALLIDS program (CBT File 731) both on the 
UPDATES page of www.cbttape.org .


   So without further ado, here are the displays.  You should be able 
to use this information to do almost any conversion that you'll need to 
do.  There's more of course, but this is the basic layout.  If there is 
an 8-character userid defined, then the old fields (PSCBUSER and 
UPTPREFX) will contan the characters '>7BYTES' with a length of 7.   
Thanks for listening.

Converting programs to accommodate 8-character userids and prefixes

[Sam Golob]

Hi Folks,

   As you probably know by now, z/OS 2.3 has introduced the possibility 
of having 8-character TSO userids and 8-character TSO prefixes.  These 
name fields were previously limited to 7 characters, ever since TSO came 
into existence.  (I think the reason for the limitation was that the 
SYS1.UADS members, representing the definition of TSO userids before 
RACF, ACF2, Top Secret etc. had to have a number at the end of them, 
i.e. IBMUSER0, IBMUSER1, etc.  So the id itself was limited to 7 
characters in length.)


   Many programs, especially TSO commands, look to find the TSO userid 
in the PSCBUSER field (7 characters long) of the PSCB control block 
(mapped by macro IKJPSCB).  Also, the TSO prefix for your session is

​IMO, the use of tabs as a "data character" is only annoying to people
stuck on a 3270 display.  I have _no_ problems with them when I'm using ssh
to get a UNIX shell. Boiled down, I will agree that using UNIX tools in a
TSO  (3270) environment is annoying.​ Equally annoying, to me, is the
column dependencies when I editing an HLASM or COBOL program from the UNIX
shell. And don't get me going on the "vi" that IBM distributes.

Hi All,

three choices for connection to our z/OS system: 

z/OS FTP 
z/OS Remote System 
z/OSMF 

I know the limitations of the FTP connection (our FTP does not let us use JES

well for the limited functionality I was using at the time. 

Since I am re-installing on a new Win10 machine I want to ask what the pros and

If it matters, our z/OS level is V2.1, heading towards V2.2 but not real soon. 

TIA for any information or advice you can provide.

​I haven't tried the following (at bottom of page)

There is a convoluted way of have a valid makefile without tabs.

If you change your makefile to read:

target: dependencies; command1; command2

If will work. If you want it on more than one line, then you can do:

target: dependencies; \
command1; \
command2

Messy, but it works.

​Ack! Pooie! If it were possible, I would set up my code so that _any_
access to an address which has not been properly "getmain'd" would
_immediately_ S0C4-?? Again, IMO, any access to "unallocated" memory is an
"overrun" situation which should be _fixed_ in the code. The previous may
be influenced from my study (not use) of the IBMi architecture wherein you
simply _cannot_ access something which is not properly allocated. Memory
allocation on the IBMi is "weird".​

See OA46291. The APAR is for z/OS V2.1 and V1.13, it is in the base for z/OS 
V2.2.


With this new function, RSM (SRM?) may decide *not* to free the frames that are 
backing some virtual area upon a STORAGE RELEASE or FREEMAIN. It is a 
significant change, IMHO, since a program might continue to (erroneously) 
access storage that has been freed but *not* getting an S0C4-10/11 because the 
frame is still assigned. Or, it may get an S0C4-10/11 at some later point if 
RSM decided to really free some such frame at a later time.


I do not want to build on that function to cheat. I'm wondering what 
information a dump would reveal in such a case. What would VSM tell me? etc.

Re: Strange application (or A.P.A) behaviour.

[Massimo Biancucci]

I'm not "into" the application enough.

It seems they use FP for different calculations. To do "capital
discounting", for instance, they use "**" operator and this is the most
hungry cpu consumer.

Maybe they prefer to work at the maximum precision rounding at the end.

Sorry for being not so effective.

Although I haven't tried, it is likely possible to create a (very ugly)

All the make tools share an annoying reliance on tab characters.

What does this exactly mean: "freemained frames"? Is it just a counter or do 
they refer to specific frames, that are kept at hand in the address space for 
faster assignment of new frame requests?

I am not surprised that those frames, if they are "available" at all, are not 
accessible anymore and access is punished with the same 0C4 as any other not 
getmained frame.

Or, better - lock up program RACFRW in PROGRAM Class, Profile RACFRW with no

ICETOOL is indeed better, since it produces ONE line per event where RACFRW 
produces several hard to read lines per event.
You can sort your records using Date in this -MM-DD format.

A nice feature is the BREAK(column,chars,CH) BTITLE('???') in ICETOOL 
statements. AFAIK, that is not possible with RACFRW.  

I am now wondering, can RACFRW report on RACDCERT commands and usage of Custom

Bruce,

You extract the SMF80 records and process it thru DFSORT.  You can also 
use RACFRW to report 

https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.ibm.zos.v2r1.icha800/racfrw.htm

Example : 

This file produces a report of failed logons for user Smith. 

RACFRW TITLE('REPORT ON FAILED LOGONS FOR USER SMITH')
 SELECT PROCESS  USER(DUMMY)
  EVENT LOGON
SUMMARY USER NEWPAGE
END

You can use EVENT to list all of your event and generate a report

Re: Back up of your largest DB

[Vernooij, Kees (ITOPT1) - KLM]

You don't always need to take a backup frequently: a backup plus logs can 
recover the DB. The less Imagecopies you take, the more logfiles you must 
process. The backup cycle then becomes a tradeoff.

Re: IBMLINK SIS Failing? Spurious Error 500's

[Larre Shiller]

Yes, indeed... I am forced to use IE and like you, I have been suffering with 
this for quite a while, but it has gotten much worse this past week.  In fact, 
at this point, it's almost unusable... almost every time I attempt to navigate 
around ServiceLink (usually starts with a "back" request), I get the error and 
I have to re-authenticate to "fix" it... but even after that, it has gotten to 
the point where I can't even navigate away from the main menu.

Re: Back up of your largest DB

Hi all:

This question I am posing caught me off guard and was wondering what the MF 
world does about Data Base backups.
The largest DB I had e been exposed to was around 60 3350 volumes and that was 
20+ years ago.
The backup of the entire DB took about 3 hours and that was by a special back 
program written by the vendor.

[...]

3350? introduced in 1975?
60 x 3350 = ~19GB. Less than one volume (3390-27 or more). It could take 
less than 2 minutes for current tape drive to write such enormous amount 
of data. It can be mirrored within seconds when using tools like 
FlashCopy or TF/Clone or ShadowImage.


Of course not only hardware parameters changed over the years. Nowadays 
a database can be caked up with no outage, doesn't matter how big it is. 
Of course the devils is in the "database" meaning.
