Rick:
That is almost a guarentee. Two weeks ago an article appeared in one of the 
bristish computer rags. The author said that there was no need for more than 1 
engine as the languages (2 or 3 mentioned) could not take advantage of more 
than one. While that is somewhat true the authore had no idea of MVS let alone 
WLM or any concept of the MVS operating system. This was a authorative 
author:.I wrote back and suggested he get some experiance under his belt before 
trying to write another article.

isolating sensitive data in coupling facility

Date:Fri, 3 Sep 2010 13:40:26 -0500
From:Walt Farrell wfarr...@us.ibm.com
Subject: Re: isolating sensitive data in coupling facility

Hello Walt- Actually this is it: it would exist somewhere an internal standard 
that used to prohibit highly sensitive data to coexist with lower 
classification 
ones on the same DASD. Hence my first attempt to map this restriction to the 
coupling facility technology.
Now, as I said in another post: we are at a very early and foggy stage of the 
project and we did not get in touch yet with the clients's actual summit of the 
Security pyramid, where such standards would have been distilled from.
I hope that we get a more precise view of this all within the next few weeks, 
and I may then come back posting again.
Thanks a lot

In fact we are foreseeing some restrictions, brought by some standards,

would prohibit data with different security classes to reside in the same
storage device. 

And how do they define a storage device, Patrick? The only time I've seen
regulations like that it was intended for DASD volumes, though I can't
pretend to have seen all such standards, of course. But it sounds like some
kind of restriction based on a perceived problem, but where they are not
telling you the problem they're trying to resolve.

Now, now. Lumping all journalists in one boat is as unfair as putting all 
computers into the same category.

Some of us go to a fair amount of trouble to verify everything we write about.

Having said that, I'll agree that *every* mainstream news story of which I've 
ever had first-hand knowledge got several significant and important facts 
wrong, such as names, ages, and confusing an employment address with a home 
address. Whether that's incompetence or just the rush to publish is unclear. 
None of them were malicious -- none of them improved (or hurt) the story for 
anyone who didn't already know those facts -- but it does speak to a certain 
lack of verification.

I suspect the original sentiment was prompted by so many on cable news

all they do is report the latest rumour without analysis as to validity,
or referee opposing speakers as if all sides of an argument have equal
validity. Not that infrequently these days, one side of an argument is
just flat-out wrong and should be reported that way.

A real journalist would not allow a guest speaker to build an argument
from facts that are really falsehoods (lies) without immediately
calling him to task - but that of course requires the journalist to have
done his homework and know more than the person being interviewed - a
rare quality now days.  People who are notorious for promoting
demonstrable falsehoods should not be given free air time merely for the
entertainment value, because there are unfortunately at least 20% of the
population that will believe anything they hear on the air, no matter

Which says:

   In the revised ITU plan, the divergence between UTC and UT will
   be allowed to grow over the next few hundred years, and could
   be reconciled by a single leap hour at some point.

We have recognized the problem and squarely turned our backs to it.
z/OS now idles user tasks down for a second at positive leap
seconds.  Is this an impact?  I'm sure an hour would be
unacceptable.

z/OS has a half-hearted approach to leap seconds in idling user
tasks.  They implemented leap seconds but simply didn't have
the courage to allow the TIME functions to return times such as
23:59:60 as specifed by the definition of UTC.

UT1 is smoother than UTC; corrections from UTC to UT1 are issued
daily with a granularity of 0.1 second.  I'd propose an even
smoother approximation, a chordwise version of UT1, with
parameters published sufficiently in advance to support
conversion of smoothed UT1--TAI for those rare cases where
TAI is required.  Of course, the mapping is undefined for
more than a few months in the future.

UNIX is worse than MVS.  POSIX effectively prohibits any
recognition of leap seconds in common time manipulation
functions.  NTP has a bizarre but probably satisfactory
accomodation to leap seconds in shifting the epoch origin
forward whenever a leap second is inserted.

 and cites:

   For instance, NTP itself can accommodate leap seconds by use of
   a parsable file of leap seconds that can be downloaded from the
   National Institute of Standards and Technology.

Our site jumped aboard leap seconds when we got a Sysplex Timer.
We abandoned them a year or two later beause of incompatibilities
with ISV software.  The problem was not with the disruption every
year or two, but because vendor products were inconsistent in
employing the correction in CVTLSO.  Here I blame not the design
of leap seconds, but vendor carelessness in their adaptation.

Somewhere I saw a quotation to the effect that It is unreasonable
to expect that a time specified as a number of seconds since the
epoch should reflect the actual number of seconds since that epoch.
I've lost the source.  I'd be delighted to recover it.

It depends. It could be allocated and not getmained. The more accurate way 
to find out is to use:

VERBX VSMDATA 'SUMMARY NOASIDS'   (For global memory)
or
VERBX VSMDATA 'NOGLOBAL SUMM ASID()' (For local memory)

From there you should be able to find out if its allocated or free.

Look in MVS diag reference..there is a chapter on VSM.
ABCs of z/OS system prog Volume 8 is also a great resource.
