Doing a little research on Performance Modeling

[Hylton Tom P]

Hi,

I've recently moved over from long time system programmer to performance 
modeling on an enterprise scale. 

My trouble is that I've spent most of my career "monitoring" and performance 
tuning on a much smaller subsystem (DB2), database, and application level,   so 
I'm way more familiar with the real time tools and knobs  that help me solve a 
problem rather than actual long term modeling of new project systems on a macro 
level.

Any statistical modeling I learned was in college long ago, so I'm pretty much 
out of touch. 

So, I'm looking to do a little research on the current  standard tools of the 
trade,   any must read texts or white papers,  and any  solid  current trends 
or standards in the field.   I'm looking at forecasting,  simulation, what if 
analysis, etc.. 


I'm familiar with a few  tools but I'd be curious to know what other prefer, 
and why. 

And just like DB2, or ALC, or any other field, there's usually a definitive 
book or paper or two.I've been doing a little browsing on the Redbooks 
site, but everything is a bit long in the tooth, especially the ones on the ZOS 
performance modeler tool, and the TDSz  ones.   

I'm not looking to buy so please go easy on the sales pitch if you're a vendor. 
  You're welcome to send me info on your product, but I'd much rather hear from 
users. 

You may drop me a private note if you'd prefer. 

TIA, 
tom

Re: IBM Research z196 Papers

[Hylton Tom P]

Just browsing thru some old posts.  

Like most, I stopped looking at any of the journals in 2009 when they decided 
to charge boatloads for something they should be handing out at every it shop, 
college, and tech school around.

Reading this post indicates that customers now have access again, but I've been 
scouring thru the research site and cannot find any indications.  Instead I'm 
directed to join IEEE.

The original article is free, but none of the rest of the journal is accessable 
from that link without membership.

What is the procedure or link for gaining access if you are an IBM customer? 

thanks,
tom

Yes ,they are available to IBM customer accounts. Related to pricing, they were 
free of charge for years and then, in 2009, IBM once made them available for 
9XX $ for each journal (there was no way to get each paper separately as far as 
I remember ) . Then with the help of some IBM executives, they  became 
available again free to customers,students and  1.9 $ for each paper for 
everyone through website. Thanks to those executives who played role on the 
decision that made them available to customers and students again free of 
charge.  I realized that price for each paper was increased again to these 
numbers through website. According to feedbacks written in here, personally I 
also wish every expert who want to read them and have to pay , can read them by 
having more reasonable price maybe...

Meral.

Re: Question for SMP/E gurus with DB2 knowledge

[Hylton Tom P]

Caveat:  Moved on to other products, so it's been a few years since I was a db2 
sysprog so I may just being dense. 

It isn't clear what "damage" you're trying to reverse, or perhaps I don't 
understand what obsolete means in this context.   

Why would the SMP/E defined SDNSEXIT dsn be classified on an APPLLY as missing 
or obsolete in your current CSI?  

If you ran step DSNTIMQ and it found a DSN to put the member in, why is it 
obsolete?

Yes, on my new DB2 installs, I simply omit the step from DSNTIJUZ, but once 
it's run, the damage is done. 

You pin-pointed my problem on older systems, the APPLY CHECK works fine, but 
when you actually run the APPLY, it can fail because of a reference to an 
obsolete SDSNEXIT library.  Your suggestion is worth a try. 

Unfortunately, once the damage is done to SMP, it's hard to reverse it.

Amdahl training was RE: more on startio...

[Hylton Tom P]

Do you mean Merriweather Post?  http://www.merriweathermusic.com/about/


The Amdahl training center there morphed into TECHKNOWLEDGE 
(http://www.techknowledge.com) sometime maybe in the mid-90's.

They still offer mainframe training, but it's been almost as long since I 
attended any so I can't attest to content or quality.  In those days, some of 
the Amdahl offerings were better than their ibm equivalents IMO. I had several 
instructors there that I thought were outstanding through the years.

every day.  There was also the Library, a bar made to look like a library.

New website for jobs and Educational materials

An IBM instructor recently passed on this link on another list, and it
seemed appropriate to pass on here for those with interest.   

http://systemzjobs.com

According to him,  it's sponsored by IBM but run by someone else.

It looks like it's primary purpose is a job board specifically for

It also has links to IBM educational materials, colleges that teach

Re: Deleting post

[Hylton Tom P]

Google publishes 2 ways to remove your own usenet posts from their
archives.   When it was "deja news", this was known as "nuking", so you
might search on that term for more info.  I've not used it, so cannot
attest to it's effectiveness, but it at least says it's still possible. 

http://groups.google.com/support/bin/answer.py?hl=en-GB&answer=186852


As for making sure it doesn't get archived in the first place,   Deja
News  created a header field called "X-No-Archive" to deal with that,
and Google still says they honor it. 

http://groups.google.com/support/bin/answer.py?hl=en-GB&answer=46487



Again, I've not used it since Google Groups came into the picture, so
cannot attest to it's effectiveness or if it works when coming from this
listserv instead of from the usenet group or if that screws it up.
Back many years ago when I used a real newsreader and participated in
usenet groups directly it worked just as advertised.   I still
occasionally visit  a couple of very old usenet groups, and still see
posts come thru with "x-no-archive" as the first line, so presumably it
still works. 

I am not familiar with other usenet archives so don't know if they honor
the same parmameters, or have alternatives.

I admit I'm not sure if this is what we're talking about or not, and I
don't know the answer to the age old question "If a post is hidden, will
anyone hear it fall in the forest?" but thought I'd add my 2 cents to
the confusion.

Re: IRFXUSER

[Hylton Tom P]

While that would solve my problem, wouldn't that cause the same problem
for the users of the original?

My reading seems to indicate that it's possible to have multiple members
of the same name in different libs, which seems to be the point of a
default name  of IRFXUSER in the function naming table, or am I
misinterpreting it?

IRFXUSER

[Hylton Tom P]

I was recently tasked to install an external function package for MQ
which givies users REXX functionality.  Since this is a supportpac,
docs are a bit sparce on details. 

The functions came bundled in a module called "IRFXUSER".   

My interpretation of the rexx manual has indicated that when you use
IRFXUSER, which is a default entry already defined in the function
table,  then you don't have to modify the function package table or link
or modify the default module.  That's cool, and exactly what I want,
but I can't seem to figure out how to get my copy recognized.  

There is an "IRXFUSER" is in sys1.linklib, just as expected.  

So far,  I've tried 
  > adding my own lib to the linklist  
  > dynamic steplib product
  > LIBDEF to ISPLLIB

All result in "function not found". 

It works in batch(IKJEFT01) with a steplib, so I know I don't have
something right, but I can't find instructions on how to get my IRFXUSER
module included in the rexx search scheme.   Is it possible to leave the
entry alone in sys1.linklib and have my functions found in a different
lib? 

Anyone familiar with doing this or can point me to a specific manual?
I can't seem to find much on the rexx reference, and irfxuser isn't
mentioned anywhere that I can find beyond the rexx bookshelf.

thanks,
tom

But I was just curious as the performance aspects, even though I didn't

I haven't used multi-character prefixes recently, but if the command 
prefix is "-DB33" then I would expect the actual DB2 command to 
immediately follow the prefix  -- i.e.,
   -DB33DISPLAY DATABASE
  without any leading comma.  For example, JES2 commands are "$command" 
not "$,command"

Ever since the shop was opened in 1999, we have had a web based service
from IBM that allowed only basic APAR searches and electronic problem
reporting of 'software defects'.  We could download PTF's. 

 

There was no charge. 

 

Now the web navigation has changed such that I can no longer access the
service. IBM is insisting that this is correct, and, oh by the way, I
should have not had any such service at all; all are fee based. 

 

Perhaps I am not using the right words. It is really difficult to keep
up with the name change game. 

 

Does anyone know what the name of that free service would be in
todayspeak?  

 

Thanks.

Re: What happened to iSource?

[Hylton Tom P]

All kidding aside, I find things like the ISource and Redbooks lists and
services like Shopseries to be extremely useful "extras" that make life
better than it used to be, and you certainly can't beat the price.

I install and maintain db2 and 18 or so support products for it, a lot of
them from IBM.  In the bad old days, even without so many products,  it
wasn't that easy to simply find and keep up with all of the new upgrades or
withdrawals for just my own stuff, much less other things that weren't
directly related but might be of interest, like maybe new hardware
announcements such as the Z9 one this week.   Now, I can look at my handy
dandy isource mail and see what's cooking as soon as it comes out, and I'm
not caught unawares when some user or manager comes out of the blue with a
question about 
version XX of product YY on machine ZZ they heard about in a sales
presentation or class somewhere.  

Same w/Redbooks.  Long ago it was very difficult for most of us to find out
when new ones were published and to keep track of which ones were of
interest.  Heck, if I remember correctly, they used to be $50 a pop and
therefore basically unobtainable, at least here.  So, it was almost like
Xmas morning or an extra birthday when you went to an IBM class and a
redbook was in the box.  Eventually, they started coming out quarterly on
CD, which you could get for a price or free if you were lucky enough to go
to a conference, but which most of us still didn't see that often.   Now,
not only can I just go download them for free,   but I get a handy weekly
email that lists them out so I don't miss ones that interest me.

There are too many areas and changes on the platform for me to ever hope to
keep up on my own, especially with annual releases of OS, and I applaud
their efforts to try to keep me as informed as possible with things like
ISource.  

It's all gravy.

Re: What happened to iSource?

I just received one this morning, so there isn't anything wrong with the
list..

Recently, the following instructions have prefaced all of the announcements,

"An increasing number of e-mail clients are using spam blockers that can
affect delivery and display of some e-mail messages.  To ensure delivery and
proper display of your IBM Announcement e-mail newsletter, please add our
e-mail address, [EMAIL PROTECTED], to your address book and safe sender

Perhaps you should just forward that to your email administator and see if

will at least prompt a response from them.

iSource missives.  I then sent an e-mail to the iSource people via the

Re: SMP sloppiness

Cathy, 

I already had an "well you should try DB2 SMP sometime" in hand when your
response popped in.

I'll just say "ditto" and say that on db2 application binds the standard
hold action or bind instructions consists of  
"You need to reference APAR x to see why a rebind is necessary.   You
may need to bind your application to make this change effective."  I've
almost got it down by heart.  

And there are MANY MANY of these just waiting for me to hunt and peck thru
IBMLINK to find.

Oh, you think that's bad? Currently, I install and maintain DB2, whose
holddata has always been prodigious.  A reference to the PTF cover
letter is not what I call a packaging problem.  What I call a packaging
problem is when PTF's that should be coreq'd are not.  About a year ago,
I put on a HIPER PTF, and the DB2 COPY utility broke.  IBM did not
believe it was their problem, so I spent many hours recreating it in
every possible way, and insisted that they fix it.  They finally asked
for my load library, with which they were able to recreate the problem.
It turned out that the PTF that "broke" COPY addressed a problem in one
internal component of that utility, and to fix the breakage I needed to
apply an earlier (non-HIPER) PTF which addressed a corresponding
component of the COPY utility.  I tried pointing out (with great vigor!)
that the later PTF should have co-req'd the earlier one, or should have
had a DEP hold, but they saw no problem with their packaging.  That's
what I get for trying to keep up with HIPER's.

Been waiting a long time to get that one off my chest!

Re: IPL periodicity

[Hylton Tom P]

Yes, I should have added the details that the lpar referenced was a member
of a sysplex, but the db2 ssid mentioned is a 
vintage legacy model that is standalone with no datasharing.  So, for this
particular environment, the db2 part of the oltp network only runs on one
lpar at a time.  So even plexed, we do have a couple of minutes when db2
data is unavailable. 

So, prior to IPL we move the db2 from lparA to lparB (less than two
minutes).  We run cics on both, so as soon as db2 is started on lparb the
appropriate regions attach there. 

lpara is then recycled, and the db2 is moved back to lpara in same manner
when practical.

As I said, our OS guys were notably wowed with how fast the system came back
to life and were practically doing cartwheels.

We do use OPS, and I think that yes, over the years we've extensively tuned
it to deal with  most things that pop out of the startup log.
Unfortunately, I don't know the details well enough to respond to your
questions.

But I did want to point out that there is a redpaper residency getting ready
to take place in August that should produce more information on avoiding
IPLs.

"these days the IPL process is
pretty much an automated cinch that takes less than 5 minutes"

The time depends upon a lot of things... and the outage is longer than the 
actual IPL, as measured at our shop the outage is from when online systems 
(TSO, CICS, IMS, Web applications) come down, to when they are available 
again. That's longer than 5 minutes at our shop, but brings up an 
interesting (to me) topic:

Do any of you "tune" the process of bringing the system down and back up?

 I'm starting to look at this  - we use AF/Operator to bring everything 
except JES2 up and down. The previous "owner" of the product, instead of 
making an event-driven automation based on message traps, put in a lot of 
15 or 30 second WAITs (i.e. "Start VTAM, wait 30 seconds, Start TSO").  So 
we have a lot of easy speed-ups due to that - but there are other, perhaps 
more sublte, things I wonder about:

1. A lot of the automation issues messages like "about to start VTAM".. 
there's acually quite a flood of messages during our IPL. Are we slowing 
down waiting for the 2074/emulator to handle all of those?

2. Does VTAM process its start l ist sequentially? If so, would I be 
better off issuing VARY ACT commands for all of the major nodes to take 
advantage of VTAM's parallelism?


I'm guessing that the 24/7-via-Sysplex crowd doesn't have as much of an 
issue, since their public face is always up even if one of the members of 
the plex bounces for maintenance.

Re: IPL periodicity

[Hylton Tom P]

I don't think you should take a few responses on the list as indicative of
SOP one way or the other, but so that new folks don't get the impression
that it's mandatory to do this quite so frequently,  I'll pipe in and say we
only IPL PROD lpars once (or maybe at most 3 or 4 times) a year.  

I'm db2 maint guy, so I don't do IPLs myself, but we recently did a 1.6
upgrade, and as I heard it from the OS guys, these days the IPL process is
pretty much an automated cinch that takes less than 5 minutes.  I thought
the strides in the console and so forth made IPL a lot
easier/quicker/automated than in the past? 

For us, we don't IPL except for emergencies, OS or HW upgrades, and for DST
fallback.

The only one that always occurs is the DST one. The DST in the fall is so
that any applications that may be logging on their own won't freak, and
isn't really necessary for most system apps per se, but does provide window
for non-critical maintenance.  

Emergency (but still planned) IPL issues are very very rare.  I believe the
last one have been in early December for us, and that may have been the only
one all of last year.   

My DB2 prod subsystems pretty much follow the same course, but with the
obvious caveat that they are more "breakable" than the OS so I do have to
make a few more maintenance outages.  But before the OS upgrade,  the
majority of the prod ssids hadn't been recycled since December either.

JCL Utility for PDS changes

I'm trying to do some pds manipulation thru JCL but haven't come up with a

1st, I'd like to delete only the members starting with "Z" in PDS1.
DELETE SYS3.PDS1(Z*)


Then I'd like to copy all of the "Z" members in PDS2 into PDS1.
COPY SYS3.PDS2(Z*) into SYS3.PDS1


I've tried IEBGENER and others, but nothing seems to be able to deal with
wildcards, or else I'm just being too dense to see it.



Can I do what I want using any native ibm utilities?

Or can I do what I want using the PDS freeware tool?

Or is there some other CBT utility that will do it?
