Re: Tectia for ZOS STC Hang - Nessus Intrusion Detection Scans?

2024-07-09 Thread Steve Estle
Everyone,

I appreciate everyone's response - to bring everyone up to date I am working 
with network security team (owners of Nessus scans) and we are trying to 
isolate with Nessus vendor (unfortunately not much help - they point to us 
working with Tectia vendor which we already are - gotta love the finger 
pointing) but there are literally 100's of these scans packed into one 
iteration which runs ~30 mins so today we plan on running wireshark to try and 
"trap" offending activity that locks up the address space.  

Dennis Mruz, to answer your question / point we've updated the SSHD2_config 
file to latest updates that vendor / development recommends and still hang 
condition persists.

Any other ideas please share but this is a fleeting one to "trap".

Thanks again.

Steve

Tectia for ZOS STC Hang - Nessus Intrusion Detection Scans?

2024-07-06 Thread Steve Estle
Hello All,

Pardon the interrupt on all the religious discussions surrounding Python vs. 
Rexx (count me in the camp of a REXX biggot given my years in ZVM and ZOS)   I 
see Rexx as a swiss army knife for so many tasks in our never ending myriad of 
tasks as Sysprogs, etc. - I do though wish Rexx could process SMF records 
better though.  BTW - I have never have done any OO Rexx tasks so can't comment 
on that world but certainly hope to at some point given all the great comments 
surrounding it's capabilities.

Now to the real reason for my post:

We run Tectia for ZOS in our environment (SSH.COM).  During our attempts to 
upgrade Tectia for ZOS to 6.7.1 it became very apparent the base SSHD2 started 
task would hang under certain conditions on our Sandbox LPAR.  After much 
further investigation it is clear the trigger to the hang conditions is because 
of our external Nessus port scans that run periodically against our mainframe 
LPAR's.  The "hang" condition issue has been reported to the vendor support 
team in which their initial response was to halt our scans which won't fly with 
our security teams of course.  Tectia SSH Dev. team seems stymied on the issue 
although they are trying to recreate in lab environment (many debug logs sent 
to them - they don't appear to like dumps - prefer the debug logs).  The hang 
strictly presents itself in the SSHD2 operator interface (in other words "F 
SSHD2, VERSION" & "P SSHD2" commands are no longer responsive, etc. and the 
task has to be cancelled to restart started task).

My key questions are:

1. Anyone else out there that is running this product on ZOS (We are running 
ZOS 2.5)?
2. If so, anyone else experienced any similar issues?  If so did you figure out 
workaround for the issue to avoid the hang conditions caused by the port scans?

If you prefer to talk offline on this please email me.

Thanks,

DFSORT Fixed Records to CSV - Trim Extraneous Blanks?

2024-05-21 Thread Steve Estle
Hello All,

I looked back at history of DFSORT questions / answers and didn't see anything 
that quite matched up on this.

My question is the following - I have a sharp App Developer I work with who is 
very good with SAS but can't quite get SAS to do what he wants - long story.  
In a nutshell he has a very large input file (~500K records) that are in fixed 
length format / fixed position format that he wants to extract select fields 
from the input records and then the output records will be written in CSV 
format.  Some of the fields are variable length in size but he knows max length 
of each of the fields.  He is interested in using DFSORT ICETOOL if possible, 
but he and I do not see anything in DFSORT App Guide that allows you to strip 
off extraneous blanks (TRIM function?) at the end of these input fields before 
it is packed into the output CSV file.

Is this doable in DFSORT?  If so, can help point me to some examples / 
suggested reading / command statements?

Thanks,
Steve Estle

Dump Analysis Best Training / Documentation

2024-05-19 Thread Steve Estle
Hello All,

Way back in the day I used to read dumps fairly handily in the MVS/XA era.  But 
have been away for so long I know things have evolved but appears everything is 
basically still intact relative to ASCB to PRB relationships.  I'm working on a 
hang/loop condition that prevents started task from being stopped normally (P 
STC) and have taken SVC dump and want to interpret it.  I'm somewhat fluent 
with IPCS and can bring up via panels, but from there am struggling with where 
to go to identify where the hang/loop condition is happening.  

Any shares of doc, presentations, tips, etc. are much appreciated as I still 
think this is one of the lost arts that in the end to be a top notch systems 
programmer you need to be able to interpret.  I know IBM used to teach whole 
classes on this but believe much of that has gone way of dodo bird...

Thanks in advance.

Homegrown ZOS Dashboards?

2024-04-28 Thread Steve Estle
Hello all you smart seasoned ZOS vets out there.  

We all know that ZOS contains a vast landscape of key mission critical 
applications and components running 7x24x365.  I'm quite curious about this 
sujbect having spent a considerable time of my career in the performance / 
capacity arena.  But what I am most curious about is whether anyone out there 
has either developed or knows of a very robust homegrown ZOS mgmt / executive 
health dashboard out there?  Possibly you did something with SAS/MXG or other 
toolsets (REXX, open source, etc.)?  I'm envisioning something that might have 
red, yellow, green sections that inspects data for ZOS ranging from SLA's, 
syslog, SMF data, performance data (response times, batch cycle completions, 
etc.), storage usage data, security data and have it all rollup into single 
view that is adaptable to a particular environment (not tied to anyone product 
- so for instance in security whatever solutions should be ubiquitous whether 
running RACF, Top Secret, or ACF2).  I know there are paid for tools as well 
and if you don't have anything homegrown maybe you have a favorite one of those 
that doesn't cost arm & leg? - possibly something open source that is easily 
adaptable.

There is no right or wrong answer here but wanted to just throw this out there 
to gather everyone's collective experiences, thoughts, and best ideas.

May the games (I mean ideations) begin.

Thanks,

Re: Anyone exploiting ZEDC?

2024-04-20 Thread Steve Estle
David, 

We are using it - biggest benefit so far has been with our backups in 
converting DFSMSDSS (ADRDSSU) backups using "ZPREF" option.  It reduced runtime 
on backups significantly (50%+) with also some reduction in CPU cycles.  We 
also are using it in other scenarios.  You do need to test though - think 
biggest areas of concern are with vendors that don't use standard access 
methods - few of note SAS, NOMAD - sure many others.   Feel free to contact me 
at sest...@gmail.com but am a big proponent of using.  I think I have white 
paper somewhere but need to track down.  One of the reasons we went this route 
is we are starting to exploit pervasive encryption which for most part requires 
extended format datasets (also required for ZEDC).  Best practice is to 
compress before you encrypt.  One other area we exploited was DFHSM and 
activated that so it now compresses migrated and backed up datasets - hard to 
measure improvement, but am sure is much more efficient than prior settings.  I 
know that large VSAM files see benefits as well - but just ensure you test 
before going to far in that direction - one other point - ZFS have the ability 
to compress as well which can be advantageous - especially when vendors send 
large ZFS packages - such as SAS does.  Areas we haven't exploited yet but are 
intriguing are JES spool space compression as well as SMF data compression.  

One other key suggestion to look at is to run a ZBNA (free software from IBM) 
study as it helps you identify good candidate datasets from your batch job 
cycles.  As others have noted it doesn't make sense to compress things that are 
relatively small - but do try and apply the 80/20 rule here.  Anytime you can 
do less I/O in batch jobs is always a good thing of course and win-win 
situation!

All the best,

ZOS Sending Logs to Sumologic Experience?

2024-03-04 Thread 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:

Technical Reason? - Why you can't encrypt load libraries (PDSE format)?

2024-01-13 Thread Steve Estle
Everyone,

Our team is knee deep into pervasive encryption rollout on ZOS 2.5 and despite 
the fact such functionality has been out for years by IBM to do this, it is 
quite surprising how many software vendors when you contact them they have no 
clue what you're talking about - that is a complete aside - I'm not going to 
name vendors here but if you want some examples you can contact me offline.

My true reason for composing this is that we've discovered the inability to 
encrypt load libraries - even in PDSE format.  I've yet to get a straight 
answer from IBM on why this is?...   Is this a "giant" technical hurdle for 
IBM?  Or is it just cause there hasn't been anyone who raised the need yet?  If 
the latter does this capability interest others here if I were to raise as an 
IBM idea - would you vote for it?

I know this seems innocuous, but we'd like to encrypt as much as possible in 
our environment and due to Top Secret deficiencies we have to encrypt at high 
level qualifier level (HLQ) (all or nothing under each HLQ unfortunately).  
Given we have load module libraries under many differ HLQ's this is posing 
difficulties in moving forward with our rollout when an HLQ does have one or 
more load module libraries as part of that HLQ.  You can only imagine the pain 
of renaming a load library given all the JCL, etc that is referencing that 
library name.

Also, while encrypting load module libraries might seem a little far fetched, 
there are of course many malicious viruses that have been launched by injecting 
code into a suspecting piece of code.

So two questions:

1. Why has IBM not already provided such functionality - can anyone speak to 
the technical hurdles to provide?
2. If I were to submit an IBM idea, can I count on this community for some 
backing here to help in upvoting such an idea submission?

Thanks for your indulgence,

Migrating Loadlibs from PDSE to PDS?

Seasons Greetings all,

I know this might sound like a strange request, but we are exploring what if 
any options there are to migrate load libraries from PDSE (version 1 or 2) back 
to traditional basic PDS's.  It appears this is highly restricted based on my 
experiences trying to perform via IEBCOPY and ISPF 3.3 (which just involkes 
IEBCOPY under the covers)?  Any thoughts/experiences on ways to do this or is 
it just one of those once you are there the "train don't go in reverse"

Re: Performance i/o problem

2023-11-23 Thread Steve Estle
Assuming you are running ZOS in native mode (not as guest under ZVM) where your 
dump/restores are occurring, I would definitely look at RMF reports - my first 
place to look is RMF Monitor III online - if not active, turn on with the 
recording VSAM files - typically "F RMF, S III" - this should show what is 
delaying / impeding the restore job.  One other question - are you restoring 
from tape or disk - what is the source device type you are recovering from.  We 
recently activated ZEDC on our LPAR's and found out dumping / restoring in 
DFDSS compressed mode speeds up our backups substantially (like by factor 3:1) 
if you have that option?  You have to specify the proper "ZCOMPRESS" option on 
the ADRDSSU dump statement to take advantage if you have that feature /  option 
active for your system / processor - we are running on Z15 hardware.

Lessons Learned - Mass Extended Format DS Conversion - ZOS 2.5

2023-11-15 Thread Steve Estle
All,

We are in the midst of rolling out pervasive encryption in our ZOS 2.5 customer 
environment.  To get there of course we need to move to extended format 
datasets (sequential, VSAM, etc) which we have minimal exposure / experience 
with today (We have multiple  100K's of datasets in our catalogs across 4 
LPAR's.  We also will be leveraging hardware compression (ZEDC) as we migrate 
things as well towards path to pervasive encryption (PV) of course following 
best practice to compress before encrypting.

Have reviewed redbooks on PV, extended format, and hardware compression 
(experiences with hardware compression so far have been outstanding - 
especially in our DFDSS backup processing).

What I'm looking for are any gotchas / lessons learned / real life experiences 
in embarking on this mass migration from basic format datasets over to extended 
compressed format DSN's and encryption that aren't documented in standard doc 
or redbooks.  Or maybe you ran across or developed some tools to aid in such 
large scale migrations?

SAS for ZOS 9.4.8 Install/Upgrade Experiences?

2023-09-23 Thread Steve Estle
Everyone,

I support a secure government environment that has limited ability to connect 
directly to vendor software download sites and am embarking on effort to 
upgrade our SAS for ZOS from 9.4.7 to 9.4.8 - you would think simple / simon 
but is my first time with this software package install/upgrade and am 
struggling with the process SAS dictates to get software from there sites.  
They use a tool called SAS download manager - one for ZOS, Windows, Linux, etc. 
 Curious for those sites that have SAS for ZOS, how are you getting software 
from SAS site to your ZOS system(s)?  SAS does not offer any sort of FTP like 
functionality and forces you to use download manager which unfortunately is not 
so simple to use - at least not on ZOS.  SAS packaging for ZOS relies very 
heavily on Unix System Services for the packaging, install, maintenance, and 
deployments/customization.

One other item, if you have engaged SAS support on regular basis, how would you 
rate your SAS support experience?  Mine to say the least is challenging - one 
of the issues we've run into under SAS 9.4.7 is interfacing SAS 9.4.7 with CICS 
web services and ATTLS - they seem to not be too savvy in this space - found 
out they do not have / nor test CICS in there ZOS / lab test environment at all 
and we have programmer who has written code for SAS to talk to CICS web 
services to extract information.  This is one of the reasons we are moving to 
SAS 9.4.8 as they repackage the OpenSSL such that it now relies on system SSL 
libraries / encryption routines vs. packing there own.

Anyways if interested in talking further / sharing experiences / or maybe have 
some good contacts relative to SAS, please let me know.  Appreciate any/all 
ideas.

Thanks in advance,

What happened to GC26-1672 Batch Local Shared Resource(LSR) Documentation?

2023-07-06 Thread Steve Estle
All, 

Unfortunately, I have to date myself a bit, but back in the 90's while with 
IBM,  I implemented batch LSR on some VSAM batch jobs that significantly 
reduced some batch jobs run time and overall CPU usage - Hours to minutes and 
~75% reduction in CPU time.  I have now the need to use Batch LSR and work with 
applications team that owns a job, but can't locate the current Batch LSR 
documentation as it applies to ZOS (we are 2.5 shop).  I'm now using ZBNA to do 
similar things on my current account (btw I can't say enough good things about 
ZBNA - thanks to John Burg and WSC team!

I've looked on IBM's documentation and Book Manager sites and cannot locate.  
I've found some references via Google search and searched this forum / archives 
and see references that the document is out there in either the MVS collection 
(possibly OS/390 collection too), but truly not sure where to locate this 
invaluable documentation anymore, but certainly thought there would be a 
current version of the doc(?)  somewhere online - but maybe not.  Any IBMers 
out here monitoring this forum, can we get a current version in ZOS 
documentation?

So here is best document number and name of document that I know of based 
online searches:

Hello Everyone,

I know this is primarily a "technical discussion" set of forums.  But wanted to 
post this anyways.  Little of my background - I worked at IBM 34+ years in a 
number of positions, but my predominant area of expertise was in MVS (SP, XA, 
ESA), OS390, etc. working in systems programming arena.  I also am highly 
skilled in performance and tuning with deep experience with tuning (RMF, SAS, 
Omegamon, and others).   I was the team lead for the MVS performance team in 
Boulder, CO for several years and got certified in this discipline. I performed 
these activities for ~20 years, but my skills are a bit rusty / out of date as 
I then moved into more leadership roles latter part of my career but know I can 
catch up relatively quickly and have been perusing docs, etc to do just that.  
I also have experience with VM as well - but not as extensive as my MVS years.  
My whole IBM career was spent in internal IS, Consulting, and outsourcing arena 
- so was in services role for 34+ years.

Anyways I'm back looking for potential job positions if anyone is looking or 
knows of available positions - happy to share resume if anyone would like to

configuring, and customizing TWS (Tivoli Workload Scheduler) on ZOS - 
especially in migrating from a "two "equal" node" TWS environment to the 
desired state with one single TWS controlling node and the other node being run 
as a TWS agent of the TWS controlling node.

I am also looking for any educational resources anyone might know (beyond 
Google) of any TWS for ZOS education which you can post via IBMMAIN reply.

If you are willing to talk about this effort further, please contact me offline 
via my email below so we might be able to talk.

Thanks much in advance!

Re: How Do I Search Current Year Postings?

2017-10-02 Thread Steve Estle
Hi Lizette,

Thanks for the feedback - it appears that when I use the "Search Archives" 
option (via webpages) I always get 2005 posts first, but I can get around it by 
using the "Since:" option (such as since 1 Jan 2017) then I get more current 
hits.  It would be really nice if when I search I get chronologically 
descending from 2017 current date vs going to 2005 by default unless I enter 
the "Since:" option?

Possibly I'm doing something wrong - here's my overall URL:
https://listserv.ua.edu/cgi-bin/wa?A2=ind1709=ibm-main===653070

should that help - if supposed to be searching different archives not sure how 
I change that setting / preference?

Thanks,
Steve Estle

How Do I Search Current Year Postings?

2017-09-30 Thread Steve Estle
Hello,

Fairly new to using these mailings / postings / system, so probably "newbie" 
question (is there a "list" for "how to" on this listserv system?)...  My 
question is how do I search the current year mailings by keyword?  Whenever I 
"Search Archives" it shows matches from 2005 backwards but not current "hits" 
in current months/years?

Thanks,
Steve Estle
