 As an aside, what is a good abbreviation for mainframe than m_f?




And my response is that I call a mainframe a computer.  Or sometimes I
call a mainframe a real computer.  As opposed to PCs; where PC stands
for pretend computer.  Or TC, toy computer.  Or the British affection
Toy Town.

Of course, there are computers embedded in equipment that rival in
power mainframes that I have worked in.   

But in a different direction - does it serve a useful purpose anymore
to separate out the blue box in our computer room from the pink box?
Sure, the pink box runs Solaris, and the blue box could run Linux. It
can feel good to call my computer a mainframe, but it may be poor
marketing to the decision makers who are planning our shop's future.

That was a BIG point that we made to the convert to Windows! people. The data 
in the reports would be in a different order unless they modified the SORT to 
rearrange the code points so that the ASCII would come out in EBCDIC order.

I'm not quite sure whether you mean EBCDIC or the awk script; if EBCDIC
yes, the awk script has never needed to be written, so unless I come
across some reason to read some EBCDIC, no.

You were talking about Unicode and 7-bit ASCII lasting long after your
death.   I just extended this to ask your opinion about a more

I wouldn't be surprised if IBM wouldn't be quite satisfied switching

Yes, there are probably some programs for which it does.  Those that
do will have to convert Unicode to EBCDIC and probably convert back
again to do their final output.  Or be rewritten completely.

I have modified programs when our IBM mainframe shop moved from DOS to
OS and the default sign in unsigned numbers changed, so that comparing

SWATCH Internet time?

What is a Swatch .beat? 
We have divided up the day into 1000 .beats. So, one Swatch .Beat is
equivalent to 1 Minute 26.4 Seconds. 

Why use Internet Time? 
Internet Time exists so that we do not have to think about timezones.
For example, if a New York web-supporter makes a date for a chat with a
cyber friend in Rome, they can simply agree to meet at an @ time -
because internet time is the same all over the world.

Where is the Internet Time meridian? 
Biel Meantime (BMT) is the universal reference for internet time. A day
in internet time begins at midnight BMT (@000 Swatch .Beats) (Central
European Wintertime). 

The Meridian is marked for all to see on the facade of the Swatch
International headquarters on Jakob-Staempfli Street, Biel, Switzerland.

When did Internet Time start? 
The BMT Meridian was inaugurated on October 23rd, 1998, in the presence
of Nicholas Negroponte, founder and director of the media laboratory at
the Massachusetts Institute of Technology.

Did a few plies of this thread get lost in the newsgroup void?

With 20-20 hindsight, all computers should have started off marking
files that way.   It's not easy changing, but it would really be worth
it.

Regrettably, it rarely works right.  MVS and UNIX early realized
the benefit of UTC (but MVS only partly -- how are ISPF PDS
members marked?  What about tape labels?)  But new systems must reinvent.  MS 
DOS and
Macintosh OS both well after started running the primary clock
on civil time.  Mac is better now; Windows is still ailing.

I suspect the mechanism is that engineers eager to get to
power-on test start their test beds with the clock on civil
time.  They procrastinate implementing the conversion routine.
Then the shipment deadline looms, and the transition is
deferred to a future release, then the conversion effort
is unacceptable.  (When will ISPF start using UTC?)

And z/OS and Unix System Services still don't do it right
for US timestamps prior to 2007.

What fraction of z/OS installations (away from the UK meridian)
still run the [E]TOD on civil time?

Especially for those sites that gradually change the time to make sure
transactions get stored in order as the clock bumps back because of
daylight savings time - but also for any multi-time zone database.

Gulp!  And the ETR will only slew a couple seconds a day.  It
wouldn't finish before time to change back.  I understand that
during leap seconds, z/OS dispatches no jobs.  The designers
likely considered but eschewed making even the leap second
correction gradually, over a few hours.

Actually, there are a few of them. I had made the same statement circa
1990, and I was pointed to an experiment that had been done to prove
that an MVS based virus could be accomplished.

One of the reasons for Production Control types to only accept source
and do their own compiles and linkages is to prevent what could be
malicious code from being copied and then infecting a business'
production load libraries.

the original mainframe tcp/ip implementation was done in pascal and

that the centers asked for categorization ... since the reports have
been free-form making it more difficult to categorize.

some amount of the transactions starting moving online during the 70s
 80s ... but would only be partially be performed ... with the
completion of process still being performed in mainframe batch (in
overnight batch window). In the 90s, there were several large
financial institutions that worked on leverage massive numbers of
parallel killer micros to implement straight through processing for
these online transactions (actually going to comletion). The issue was
growing business and growing global business was putting extreme
pressure on the overnight batch windows (more work  decreasing
size). However, the parallelization technology they were using added two
orders of magnitude overhead (compared to the mainframe batch)
... completely swamping any anticipated thruput increase (several
projects were billions into the efforts before doing any serious look at
the speedsfeeds and then declared success and abandoned the efforts).

On the other hand there was a lot of mainframe clustering, continuous
availability and disaster survivability done in the 70s and early 80s
... that never made it out as product. For instance at the hillgang user
group meeting yesterday ... they had presentation about new
single-system-image cluster support for z/VM. We had done that in the
mid-to-late 70s for the HONE system (world-wide online marketing and

When the sources of faults are examined in detail, a surprising
picture emerges: Faults come from hardware, software, operations,
maintenance and environment in about equal measure. Hardware may go
for two months without giving problems and software may be equally
reliable. The result is a one month MTBF. When one adds in operator
errors, errors during maintenance, and power failures the MTBF sinks
below two-weeks.

Re: big iron mainframe vs. x86 servers

2009-10-21 Thread John P. Baker
The big advantages of the IBM mainframe architecture have always been
application upward compatibility, I/O throughput, and RAS (reliability,
availability, and serviceability).

Application upgrade compatibility requires both hardware instruction set
upward compatibility and software system interface upward compatibility.
Intel has made some significant strides in recent years in terms of hardware
instruction set upward compatibility, but Microsoft's software system
interface upward compatibility is a joke.  Windows release boundaries have
been invariably disastrous, and service packs have been little better.

I/O throughput on z System z processor complex is second to zone.  No PC I/O
architecture can come close to the throughput exhibited by a small System z
processor complex.  A large System z processor complex is in a universe all
its own.

IBM RAS (reliability, availability, and serviceability), developed and
evolved over 45 years, is second to none, and RAS is what keeps businesses
in business.

For sheer number crunching, I might pick an IBM Power[n] box.  If I want to
go on the cheap, I might pick an Intel box.

For transactional processing involving vast databases, anything other than a
System z processor complex is irresponsible.

Give that staggering number of financial transactions processed on a daily
basis, over 90% of which is done on large-scale IBM mainframes, is it not
strange that you have never heard of a mainframe virus?  IBM RAS and IBM
Security (whether implemented via IBM RACF, CA ACF/2, CA-Top Secret
Security, or some other External Security manager (ESM)) is what keep these
systems running.

In this case, I would bet it depends on what those x86 servers are doing. If 
they are a Beowulf supercomputer cluster, then the z10 is NOT going to beat it. 
But if they are Web servers? Or even application servers?

Speaking of such. The z10 is said, by IBM, to be the fastest (clock time) 
CISC processor. So, does that mean that a single IFL processor could outperform 
any single x86 (Xeon?) single threaded processor around for something which is 
CPU intensive, such as numeric computation? To be fair, let us assume that 
this computation is being done in Java by using the identical .class file. I 
know that isn't fair since the JVMs are not identical. But it is about as 
fair as I can think of. Or perhaps the same C code compiled and run on Linux 
using the same version of GCC.

code and a token ring conenction to the mainframe.  every time it burps i 
get indigestion.  replacing it means using smtp to replace telephony -- 
swapping one poisonous snake for another breed.

As an aside, what is a good abbreviation for mainframe than m_f?  I would 
like to reserve that for M$, Office and InfoPath at the moment.

  Interesting. I'd think the number could be less than one.

   How many Mainframe engines = 1500 x86 boxes?

  It depends.  Could be as few as one.

 
 In this case, I would bet it depends on what those x86 servers are 
 doing. If they are a Beowulf supercomputer cluster, then the z10 is 
 NOT going to beat it. But if they are Web servers? Or even 
 application servers?
 
 Speaking of such. The z10 is said, by IBM, to be the fastest 
 (clock time) CISC processor. So, does that mean that a single IFL 
 processor could outperform any single x86 (Xeon?) single threaded 
 processor around for something which is CPU intensive, such as 
 numeric computation? To be fair, let us assume that this 
 computation is being done in Java by using the identical .class 
 file. I know that isn't fair since the JVMs are not identical. But
 it is about as fair as I can think of. Or perhaps the same C code 
 compiled and run on Linux using the same version of GCC.

Um, the 13-slide show left me waiting for the information to 
start.  I found it gossamer-thin, so lite that I believe it would 
struggle even to get into an airline magazine.


take care all,
Graeme

Fair - but incomplete.
