Re: RACF, external password management

[Colin Paice]

I wrote One minute MVS: What is IBM Multi Factor Authentication on z/OS?

and a series of implementation posts starting with Multi Factor
Authentication(MFA): Planning.

I found the MFA product easy to set up and use.  I had little problems like
ordering the wrong YubiKey which did not support MFA!

Re: TELNET PROFILE, strictly PDS?

[roscoe5]

I could not find definitive doc saying a PDS/E was/wasn’t allowed, but I am 
convinced it is. Thanks.

Over the weekend I created a PDS/E and copied the members, made my update, and 
I’m awaiting Change approval to do any Obey from the new Library to pick it up, 
temporarily. Then the plan is to change the TELNET proc to point to the new 
Library. Over the next several weeks I expect IPLs will pick up the Library. 
Until then we will be slightly on uneven ground.

I read about two different types of PDSs, type-1 and type-2. In a z/OS 2.4 
shop, do we need to specify or is type-2 created by default?

Thanks again!

You will, at some point need to restart TCPIP to pick up the new PDSE in the 
Profile datasets.
TYPE 1 PDS/E is sufficient for this purpose.

Re: EXTERNAL EMAIL: ZOS Sending Logs to Sumologic Experience?

[Paul Feller]

Steve, to add to what Jerry and Charles have said.  I don't have any experience 
with Sumologic, but I'm going to guess it will need data sent to it in a format 
it will understand.  The place that I retired from was using the BMC product to 
send data to Splunk.  The BMC product allowed us to pick which SMF records to 
look at and which fields in those records to format and send to Splunk. We ran 
an agent on several lpars to capture data.  One of the SMF record types we 
looked at was related to RACF information.  We also looked at SMF record types 
related to CICS activity and batch processes. 

As a side note to Charles.  We started out with the product when it was called 
Correlog.  We had looked to several products and went with Correlog.  My 
impression is that it is a nice product.

Re: Can DFSORT assign custom Return Code values?

[Cameron Conacher]

The situation is that I have three different environments.
If we are in development, lets ignore the email
If we are in pre-prod, let’s assume someone is perform a User Acceptance test.
If we are in production, we should jump in and deal with remediation.

When the email is sent, I have embedded Symbolics in the email text itself, 
meaning I need to use  //SYSUT1   DD  *,SYMBOLS=EXECSYS, with IEBGENER.

In this situation, I cannot put the email text in a PDS as I would not be able 
to use the SYSBOLS= clause with IEBGENER,
On the other hand I could put all the email text into a PDS member, and 
pre-process this email text performing all the Symbolic substitutions, and 
create a temp file that has already had all of the substitution performed, pass 
it to IEBGENER without the SYMBOLS= clause, and go from there.
Sri, showed me how to gather the available data from the existing System 
Symbolics, and I can pass other data I need via PARMs.
So I am all good to go now.

However, I am going to look into writing a tiny C program, that I can call as a 
utility to assign a return code value. Just to see what it takes.

I was looking to run a utility that would simply generate a Return Code value, 
I could use to conditionally execute a JOBSTEP.

I’m not too familiar with Sumo Logic, but they say they can ingest several 
different log/event feeds, notably LEEF (Log Event Enhanced Format). zSecure 
Alert and zSecure Audit do a great job providing LEEF (and other format) feeds 
to the likes of Splunk, QRadar, ArcSight, and others. Here’s an entry point 
into the zSecure documentation to explain more:

https://www.ibm.com/docs/en/szs/3.1.0?topic=deployment-data-preparation-siem

To set expectations a bit, even the best z/OS event feed(er), with lots of 
customization and enrichment options, can only partially help Sumo Logic and 
its users interpret, correlate, and understand z/OS-specific events. There’s a 
lot of work that goes into QRadar’s Device Support Modules (DSMs) and AI to 
understand what’s really happening in z/OS in context, and to display 
meaningful information to users who don’t necessarily know much about z/OS 
specifically. So just be prepared to do at least some work to make the feed(s) 
from z/OS more useful within Sumo Logic — work on both ends. In other words, 
most of the value in this class of dashboarding and analysis tools is in, well, 
how much useful analysis they provide. Feeding the tool (even with the best 
feed) is only part of the story.

Metaphorically speaking you could feed hospital-related events to a control 
center at a steel manufacturer. And that hospital event feed could be the 
world’s best feed, with lots of enriched data and everything you could ever 
want to know about what’s happening at the hospital. But a steel manufacturer 
that understands steel-related events — and maybe also nickel-related, 
copper-related, and car manufacturing-related events in a pinch — could be 
bewildered when it receives hospital-related events. True, it’s all English (or 
some other common language), but what does it mean when there’s a gray alert 
followed by a pink alert? Are those two events related? And what is a gray 
alert anyway? Or a pink alert?

Answering my own questions, these events could be related. “Gray” means a 
combative person, and “pink” means an infant abduction. But I didn’t know that 
until 5 minutes ago.

Re: How to reduce the overhead of WLM?

[Graham Harris]

A few years back, I did a deep dive into tuning CPU usage across a
multitude of very small z/OS guests under z/VM, and WLM was certainly a big
hitter for many of them, but as there were so many instances, I was able to
see notable differences in WLM use between "LPARs", which was obviously "of
interest".
The upshot seemed to be that WLM costs had a fairly firm relationship with
the number of active address spaces on the "LPAR", presumably down to the
amount of sampling that WLM has to do against each address space every
250ms (I think).  I did enquire of IBM as to whether the sampling rate
could be "adjusted", and that came back with a negative response (not
really a surprise).
So the obvious answer may be to only have address spaces started, when they
are only really needed to be there.
Although you may need to assess the cost of stopping/starting those address
spaces, versus the background WLM cost.

Re: How to reduce the overhead of WLM?

[Jim Mulder]

  The most important thing is RMPTTOM for reducing the SRM timer pop overhead.
Note that Timer DIE processing is uncaptured time.

  My IEAOPTxx  for running under  VM  has

RMPTTOM=3 /*REDUCE SRM INVOKATION FREQUENCY ON VM */ 

  And that is a value we set a couple of decades ago, and haven't thought much 
about it since.
You might want it even higher for faster machines than we had back then.

  I suggested some years ago that SRM should self-tune the timer pop interval 
to be less frequent at low utilization, but I haven't gotten any traction on 
that so far..

Subject: How to reduce the overhead of WLM?

This is probably a strange question, but is there a way to reduce WLM cpu 
usage?   Here's the situation: 

- The system is a lightly used development system.  Unless something is in a 
loop (very rare), CPU % probably is usually less than 10%.  And except for 
system regions & CICS, it's rare to have multiple jobs running concurrently. 
- Only one processor defined to the VM. No ZIIP either.  
- We are charged for CPU cycles.
- WLM is the highest consumer of CPU.  JES2, TCPIP, ZFS and SDSFAUX round out 
the top 5 consumers. 

There is a lot of information about WLM tuning, but as best I can tell almost 
none of it relates to reducing WLM usage.

From reading the Init & Tuning manual, I'm trying these settings: 
AIMANAGEMENT=NO
HIPERDISPATCH=NO 
CCCAWMT=45   
RMPTTOM=15000

I was thinking that perhaps reducing whatever processing intervals I could 
might help.  But I can't tell these changes made a difference.  (I don't have a 
tool to measure WLM usage.)

Any suggestions would be appreciated.

TIA,

Wendell

Can DFSORT assign custom Return Code values?

[Cameron Conacher]

Hello everyone,
From what I have read this is not possible, but I decided to throw it out there 
to see if something is possible.

I have a block of JCL with a bunch of steps.
I have symbolic parameters assigned. (JP1/JP2 SYSPLEX Symbolics for DFSORT)

I was looking for a Utility that would examine the value of a Symbolic and 
assign a User Return Coe value. RC1 = Development; RC2 = Pre-Production; RC3 = 
Production?
I need a Return Code value to be able to conditionally execute subsequent JOB 
steps. I cannot execute steps conditionally based on Symbolic Variable values.
IF Step001.RC = 0 ….Development

I could write a tine program to do this.
I was hunting around for a utility to do this.
DFSORT is my go to Utility but as mentioned, I believe it is not suitable for 
this task.
I believe I could set RC0 or RC4 or RC16. RC0 and RC4 generate a message and 
continue, but RC16 generates a message and terminates. I think this 
(Termination) would be unsuitable.

I was to be able to assign one of three different Return Code values (any 
value) that I can let check to determine if I am running in Development, 
Pre-Prod or Production, and then execute steps related to the specific 
environment.
Not something I absolutely need since I could write a tiny program for this.

Just curious, and I think my ADHD has just sent me down another rabbit hole 

I could do this in Easytrieve. Or COBOL. Or Assembler. Or Rexx. Or …..

Hope this makes sense.

Thanks

ZOS Sending Logs to Sumologic Experience?

[Steve Estle]

All,

We are embarking on an endeavor to explore sending logics to a tool called 
Sumologic(sumologic.com).  For those who are unaware, Sumologic is a competitor 
to Splunk and contains a very powerful real time log parsing analytics engine 
which can be used to build dashboards, alerts, and more.  My basic question is 
has anyone heard of or actually been involved in devising ways to send ZOS logs 
into Sumalogic - our initial efforts will be security related, but for now am 
just asking if anyone has any experience in this realm at all?  Or maybe you 
are doing something similar to Splunk?  If so, you can post in forum or feel 
free to reach directly out to me:

Thanks much,

I think I did what you want, many years ago.
A very small C program something like

{
if (strcmp(argv[1],argv[2]) == 0 return 0
else return 4;
}
//S1 EXEC PGM=IFPROG,PARM="DEV,"
// if S1.RC == 0  they are the same

Not something I absolutely need since I could write a tiny program for this.

Cameron,

DFSORT has limited ability to set a return code but not the way you want. 
However, I think we can solve your issue quite easily by validating the symbol 
and only generating the steps that needs to run for that Symbolic. Remember 
DFSORT has the ability of reading the system symbols and determine the LPAR it 
is running.

Please send an offline email with your complete requirement and I will show you 
a way to do it.

Re: Can DFSORT assign custom Return Code values?

[Doug Henry]

Another simple way to do this is a simple Rexx exec using MVSVAR to get the 
system symbol that you want . See 
https://www.ibm.com/docs/en/zos/2.5.0?topic=tef-mvsvar to see examples of how 
to do this.

Re: TELNET PROFILE, strictly PDS?

[Radoslaw Skorupka]

General remarks:
There are three flavours of "partitioned data set":
- PDS
- PDSE (now described as v1)
- PDSE v2

PDS/PDSE can hold data members or program members.
For programs, the difference between PDS and PDSE is significant. 
However for brevity let's stop talking about programs.


Now about data members like TCPPARMS, CLIST, REXX, etc.
Very few programs/applications distinguish difference between PDS and 
PDSE. That means you can replace PDS with PDSE almost everywhere. With 
the exception for IPLPARM, PARMLIB and PROCLIB I would not even check. :-)


Now PDSE v1 vs PDSE v2 - I don't know *any* scenario when the difference 
is important for the application.



BTW: when you install z/OS you can change PDS to PDSE. For hundreds of 
libraries only few (3? 5?) cannot be changed. However people tend to be 
reluctant and most of "PDS by default, but it could be PDSE" libraries 
are still created as PDS.


Sometimes it is justified by cross-sysplex sharing, but IMHO it is just 
a pretext.

Over the weekend I created a PDS/E and copied the members, made my update, and 
I’m awaiting Change approval to do any Obey from the new Library to pick it up, 
temporarily. Then the plan is to change the TELNET proc to point to the new 
Library. Over the next several weeks I expect IPLs will pick up the Library. 
Until then we will be slightly on uneven ground.

I read about two different types of PDSs, type-1 and type-2. In a z/OS 2.4 
shop, do we need to specify or is type-2 created by default?

Thanks again!

Presuming these are three different z/OS instances. why not just use

Doug,

As I mentioned earlier you don't need REXX to get the MVS variables. DFSORT is 
quite capable of reading the SYSTEM symbols.  If your system has all the 
symbols defined, then you can use the following DFSORT JCL

Re: Changes to user's TSO PROFILE

[Lennie Bradshaw]

The TSO prefix is stored in an unprotected control block (the ECT I think). As 
such, almost any program running in the TSO session can change it. I don't 
think that any of RACF, ACF2 or TSS can protect you against that.

Re: Can DFSORT assign custom Return Code values?

[Binyamin Dissen]

Not exactly sure what you are trying to do, but .

it should be a simple rexx procedure 

/* REXX */   
STRING = "TEST PROD WHATEVER"
RCS = "4 8 12"   
 
DO  JJ = 1 TO WORDS(STRING)  
IF  WORD(STRING,JJ) = ARG(1)  THEN  RETURN WORD(RCS,JJ)  
END  
RETURN 102   

Invoke it with 

//   EXEC  PGM=IKJEFT1B,PARM='%SILLYREX '

And this step will set RC to the translated string value.

long gone for the vast majority of cases.

(Things like PROFILE PREFIX are not to be confused with ISPF preferences,
which are saved in a user-specific ISPF profile dataset.) TSO
preferences/attributes are saved in the in-storage UPT (mapped by IKJUPT),
and written out to UADS/RACF/ACF2/TSS during normal TSO logoff.

As Allan said, you can compress an in-use PDS using IEBCOPY.

//CMPEXEC  PGM=IEBCOPY
//SYSPRINT DD  SYSOUT=*
//SYSUT3   DD  UNIT=SYSDA,SPACE=(CYL,(90))
//SYSUT4   DD  UNIT=SYSDA,SPACE=(CYL,(90))
//INDD0DD  DISP=SHR,DSN=

You might have to adjust the SYSUT3/4 space.

How to reduce the overhead of WLM?

[Wendell Lovewell]

This is probably a strange question, but is there a way to reduce WLM cpu 
usage?   Here's the situation: 

- The system is a lightly used development system.  Unless something is in a 
loop (very rare), CPU % probably is usually less than 10%.  And except for 
system regions & CICS, it's rare to have multiple jobs running concurrently. 
- Only one processor defined to the VM. No ZIIP either.  
- We are charged for CPU cycles.
- WLM is the highest consumer of CPU.  JES2, TCPIP, ZFS and SDSFAUX round out 
the top 5 consumers. 

There is a lot of information about WLM tuning, but as best I can tell almost 
none of it relates to reducing WLM usage.

From reading the Init & Tuning manual, I'm trying these settings: 
AIMANAGEMENT=NO  
HIPERDISPATCH=NO 
CCCAWMT=45   
RMPTTOM=15000

I was thinking that perhaps reducing whatever processing intervals I could 
might help.  But I can't tell these changes made a difference.  (I don't have a 
tool to measure WLM usage.)

Any suggestions would be appreciated.

TIA,

Wendell

Re: ZOS Sending Logs to Sumologic Experience?

[ITschak Mugzach]

Technically, it is not an issue. You can send everything using Rexx (I can
supply a sample for syslog). The main issue is converting the input to a
format familiar to the syslog parser. In my code I use CEF.

So, what are your input sources?

Re: 35th International Rexx Symposium in Birsbane (Australia) about to start

[Bob Bridges]

Well, let me focus on that one thing.  If I can define a class as a cluster of 
data values and/or subroutines, and instantiate objects in that class, then 
isn't that "object-oriented" even if it doesn't have any features to define 
inheritance from other classes?  You may think it's a pretty feature-poor 
example of it, but what else would you call it if not "object-oriented"?

I'ld say that to be  OO it must at least have inheritance.

Well, yeah.  But a) I'm not far enough into that debate to understand all the 
issues and distinctions, and b) at any rate "object-oriented" means SOMETHING.  
As I said, when he wrote "dynamic" I was sure he didn't mean just "lively" or 
"ever-changing".

Heck, I'm satisfied if "object-oriented" means merely that I can define objects 
and create instances of them.  All the other stuff about inheritance and other 
even more arcane features, they're great, but I wouldn't say a language cannot 
be object-oriented without them.

Actually, there's been a decades long language war over what object-oriented 
means.

Re: Changes to user's TSO PROFILE

[Lennie Bradshaw]

I think the prefix is remembered across TSO sessions, and it is stored in the 
TSO segment of RACF. However, it is stored at LOGOFF time, so interim changes 
are not recorded.

Protect, no, but since many of the fields in the TSO profile are recorded in 
the security ID, mightn't they at least track the changes when they occur?

The TSO prefix is stored in an unprotected control block (the ECT I think). As 
such, almost any program running in the TSO session can change it. I don't 
think that any of RACF, ACF2 or TSS can protect you against that.

Re: EXTERNAL EMAIL: ZOS Sending Logs to Sumologic Experience?

[Jerry Whitteridge]

We used a product to send syslog/smf data to splunk called Correlog - since 
acquired by BMC and I don't know its new same. I don't think you will have any 
success in doing this without some agent on the mainframe that can extract and 
then send the data.

All,

We are embarking on an endeavor to explore sending logics to a tool called 
Sumologic(sumologic.com).  For those who are unaware, Sumologic is a competitor 
to Splunk and contains a very powerful real time log parsing analytics engine 
which can be used to build dashboards, alerts, and more.  My basic question is 
has anyone heard of or actually been involved in devising ways to send ZOS logs 
into Sumalogic - our initial efforts will be security related, but for now am 
just asking if anyone has any experience in this realm at all?  Or maybe you 
are doing something similar to Splunk?  If so, you can post in forum or feel 
free to reach directly out to me:

Thanks much,

I think in ACF2 it is the PREFIX attribute in the user's profile record.

Yabut... Where else could it be recorded? It used to be in UADS, but that's
long gone for the vast majority of cases.

(Things like PROFILE PREFIX are not to be confused with ISPF preferences,
which are saved in a user-specific ISPF profile dataset.) TSO
preferences/attributes are saved in the in-storage UPT (mapped by IKJUPT),
and written out to UADS/RACF/ACF2/TSS during normal TSO logoff.
