2010-04-07 Thread Schuh, Richard 
The 5.3 documentation seems to indicate that the only DPA that counts is that 
below 2G. Is that right or has the documentation simply not been brought up to 
date? If it is true, it would appear to make the default SYSLIM based on the Q 
FRAMES response 513876 / (4 * 2050) or 62.667 GB, assuming that I have picked 
the right number for the DPA. It is a whole 'nother ball game if all DPA is to 
be considered.
  
  
The second qualification, as stated below, is not well stated. For example, 
defined how? Perhaps the DASD space allocated as PAGE, something that might not 
be constant from one ipl to another? That is the only definition that comes to 
my mind. How does one have paging space defined that is not "for CP use"? The 
qualification seems to imply that it is possible.

Re: V-disk

2010-04-07 Thread Quay, Jonathan (IHG) 
The built-in default system limit is the minimum of:

* The amount of virtual storage that can be represented by
one-quarter of the usable dynamic paging area (DPA), based on the fact
that each gigabyte of virtual disk defined requires 2050 frames of host
real storage

* The amount of storage represented by one-quarter of the paging
space defined for CP use

Re: acm/vmware

2010-04-07 Thread Gabe Goldberg 

Regarding z/Journal and Mainframe Executive being separate from IBM, 
absolutely. Regarding the IBM magazine, also somewhat right: it's 
produced/distributed by an external company, though with much editorial input 
from IBM. But being a captive publication, articles are too often more product 
descriptions than substantive business-case illustrations of mainframe value.

To be fair, though, IBM has other active efforts: a large assortment of 
teleconferences highlight current customers' successes with VM, Linux, System 
z. And Gerry Araneo (who also hosts most telecons) works to get System z 
stories told. I wrote up Government Accountability Office and Antares (large 
Mid-west insurance company) for him, and I'm not the only person writing these 
profiles for him. And IBM issues press releases on mainframe customer stories. 
Unfortunately, I doubt that these press releases and case studies reach 
everyone who should read them.

Yup, some companies -- some legal departments -- make the profiling process 
weirdly adversarial, if they even allow it to begin. There's no reason for 
that, though, since the goal is simply to let companies brag about their 
technological brilliance. And to let IBM and other vendors involved bask in the 
reflected glow. Sites profiled seem to like the results, though others decline 
the honor. Go figure...

Richard Schuh said:

No argument here. One reason it is so tough is that some shops would require 
that every word pass through a legal department filter. His makes the real 
burden one of distinguishing between dragons and windmills.

   EPARM='S=N PREFIX=75736572636F653D3334303433343034'
and Exit LPRXONE took it but it didn't work.
