 John,
 
 Where are you getting the message.  It certainly should be 
 available to the public, and many of my readers have recently 
 downloaded it.  Here is a direct link - 
 http://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/PRS268.
 
 Does it occur when you try to download just the program or 
 the program plus Java?  Is anyone else having trouble?  It 
 only supports Windows XP.

Program with Java (not sure if I need the IBM Java; my workstation
already has the Java 6 JRE installed).  I get an error box with
Internet Explorer was not able to open this Internet site.  The
requested site is either unavailable or cannot be found. Please try
again later.  Same result for the program without Java (just now tried
that).

When I manually navigate to the correct folder on
ftp.software.ibm.com, right-click on either package and select Copy
to Folder..., I get the access denied error.

A colleague said he downloaded it earlier yesterday morning.  I wonder
if IBM has their server configured to remember domains that have
downloaded it, and limit each requesting domain to one download?

Sounds like a firewall/proxy error.

Doubtful.

 John,
 
 Marianne Hammer of IBM gave an excellent SHARE presentation 
 that showed the changes between releases.  Go to 
 www.share.org, click on Orlando Proceedings to the left, then 
 search for session #2530.  There is first a section about 
 going from z/OS 1.7 to 1.8, where the goal had changed from 
 being +/- 1% of equivalency to improving the performance.  
 The performance improvement ranged from 1.6% (low n-way) to 
 4.8% (high n-way).  For 1.8 to 1.9, the goal was a 5% 
 improvement and their LSPR benchmarks showed a 5.2% improvement.
 
 Your mileage may vary, so it's very important to use WSC's 
 free tool called SoftCap (WSC PRS268), which lets you enter 
 the breakdown of your workloads to see what your expected 
 change will be.

Thanks for the info.  It appears that, despite the inviting verbiage
on the SoftCap download page, the tool is not generally available for
download.  I get access denied when I try to download it.

I had no intent to confuse; if I did that I'm sorry.
My comment was more intended to say that you cannot reduce resource consumption 
by 5% every release, because eventually that would tend to zero.
And, we know MVS does not consume zero resources.

We are just about to start the migration from z/OS 1.7 to z/OS 1.9.
 
Would someone provide a ballpark percentage increase in the amount of

Seriously, that's the first time I ever heard that.  It used to be a pretty

IBM is scraping the bottom of the barrel looking for performance these 
days. Example: the z10 added a bunch of new instructions that make

instructions in the pipeline. They even added instructions to help an 
application micro-manage its cache usage!

I believe IBM currently uses an unofficial goal of a 5% decrease in 
utilization per release.

Actually, it's simpler than that.
IBM used to promise it would not cost more for the same functionality in each 
subsequent release.
Mind you, if you exploit new technology all bets are off.

(0.95)**N becomes infeasible after awhile, since this tends towards zero.

(Also, I cannot find it on the website[s], but I remember the promise from many

John,

Marianne Hammer of IBM gave an excellent SHARE presentation that showed the
changes between releases.  Go to www.share.org, click on Orlando Proceedings
to the left, then search for session #2530.  There is first a section about
going from z/OS 1.7 to 1.8, where the goal had changed from being +/- 1% of
equivalency to improving the performance.  The performance improvement
ranged from 1.6% (low n-way) to 4.8% (high n-way).  For 1.8 to 1.9, the goal
was a 5% improvement and their LSPR benchmarks showed a 5.2% improvement.

Your mileage may vary, so it's very important to use WSC's free tool called
SoftCap (WSC PRS268), which lets you enter the breakdown of your workloads
to see what your expected change will be.

Cheers!

Subject: z/OS 1.7 to z/OS 1.9 Migration - Increase in CPU/MSU Consumption

We are just about to start the migration from z/OS 1.7 to z/OS 1.9.
 
Would someone provide a ballpark percentage increase in the amount of
CPU resources between the two releases so we can estimate the monthly
increase in our z/OS base monthly billing?

TIA,

-jc-
