Subject: 3270 Emulation for Large Site - HELP!
Organization: Independence Blue Cross
Date: Tue, 10 Nov 92 16:46:54 GMT

All...

HELP!  I have the task of providing 3270 emulation to a shop
who's workstation population will be growing by 250 workstations
over the next 90 days.  This will give me a total of 600.

Currently, I'm running SunLink SNA3270 over three 56kb gateways.
And...Over the last few weeks I've seen response time go from acceptable
to horrendous.

QUESTION:  Who, if anyone, is running 3270 emulation of this scale on
Suns?  And, How are they accomplishing this and with what end results.
All totaled, I will have to provide approx. 1500 sessions by the first
of the year.

I've have pissed VPs calling me everyday and I can't take it anymore.
I've tried throwing hardware at SNA3270 with no avail.  Perhaps telnet
3270 would be a superior solution.

Can someone please help

Thanks in advance

I'm looking for a version of tn3270 that can be used on the Altos 2000 series
System V microcomputer used for our library system.  The versions that I have
found via archie and anonymous ftp seem to be for BSD, not System V.  Have I
not looked hard enough, or is System V too awful to bother with?

I'm not a member of this list so I ask any Samaritans who might be able to
help a neophyte with this problem to direct responses to me at the BITNET

Before you pay IBM for a version of x3270 you should know that x3270 is
in the public domain. I'm not saying the P.D. is the same as the IBM
version, but the P.D. is VERY good. I would suggest that everyone thinking
about buying the IBM version first take a look at the P.D. version!
Why pay for something you can get for free?

Hello, I would like to hear from anyone who may have modified the Mac
version of tn3270 to remove the menu bar.  I would like to include limited
network access for a public informational kiosk.  As it comes, out of the
box, it's a very nice Mac application.  I'm looking for a version that
prevents users from slipping into Finder, changing network configuration

   This homebrew solution made an otherwise necessary upgrade to a
   piece of IBM hardware unnecessary, at a savings of $750,000 to us.


Why did you need to devote any hardware to it? At Lehman we just wrote
a script to wrap an xterm around tn3270. With the mainframes in our
name server, you just type 'xtn3270 {hostname}' and you get a 3270
session in a window. No extra hardware needed (on the UNIX side). Tjis
works well for over 500 users, and there is no failure bottleneck, as
there is with your gateway machines. Or perhaps I'm missing something?

We are in the process of abandoning this homegrown solution to buy
IBM's commercial package "x3270". It is also telnet-based, and has a
whole bundle of neat end-user features. Kinda expensive, though.
There's another commercial one available called OCS, and one that came
by in misc.sources recently.

Whether you buy it or roll it, though, the TCP/IP approach really
beats the SNA approach on scalability, price, and headache-reduction.

We use the one from the net - can't beat the price!  Works fine for us.
We did just buy a neat X-windows based Tandem 6530 emulator - should be
here Real Soon Now.

True, so long as you do the tn3270 protocol conversion in a gateway - 3090's
are awfully expensive protocol converters.

Subject: re- VR and Education

Subject:     re:  VR and Education

This topic has generated some interesting opinions which have
seemingly stemmed from almost views with regard to the educational
process and our role as educational technologists.  It would also
seem clear that certain other problems are having a strong influence
on all of us in our individual environments.  Clearly the path of
development shows that technological capability has a longer
lead-time on common practice than most educational technologists
would really like.  This inertia has benefits in slowing the process
down so that the novelty of the technology has given way to novel
approaches in its educational use.

Multimedia is going through this phase now.  It is neither
commonplace nor rare.  It has no well defined standards related to
implementation, architecture or expectations of quality.  In real
terms, it could be argued that the only quality control that exists
in education is reliant upon where the STUDENTS will draw the line.

As educational technologists I believe it is our responsibility to
understand the application of the technology as well as the
technology itself.  To simply tack some additional technology on to
the process of education, without restructuring the overall
implementation of the resources available, goes against some of the
fundamental principles of instructional design.

Mark Whitman's views on the changing nature of education are an
accurate reflection of the problems faced by most of us who wish
encourage movement towards supplementing (NOT REPLACING) the valuable
human resources with appropriate technology.  Whilst recognising that
we probably all succumb, at least in some ways, to the temptations of
"new toys" as implied by Ian Hart, let us not forget the rich
improvements to educational technology that have in fact had their
origins in these sources.

I believe that VR in education is long way off at this stage.  We
have not even fully come to terms with multimedia yet.  At the same
time, however, unless we devote some money to the research of this
"new" medium, we will not be able to explore or exploit its
possibilities when the technology matches the expectations.

Subject:      Re: Education & Virtual Reality

Remi,

I think that if you will re-read my original note you will see that I
specifically stated that increased use of technology WILL NOT replace the
teacher, but will redefine the teacher's role from source to mentor.  I think
this is in agreement with your statement.

In response to where have I obtained my information, I guess it comes from my
15 years as a practicing K-12 educator/administrator and my 5+ years as a
school technology/reform consultant working directly with school districts
seeking to change a system that annually dumps up to 30% of its clientel into
the world unfit to participate as productive citizens.

Technology provides education a set of powerful tools, not a single all-
encompassing method for teaching every child everything.  No doubt, there
are those situations in which the traditional method of the teacher-as-expert
is preferred; however, there are also many situations where many students
can prosper best by the teacher moving beside the student and allowing the
student to investigate knowledge directly UNDER THE TEACHER'S GUIDANCE.

There was also a second posting which stated that hypertext is currently
much more valuable to education than multimedia and/or VR.  I agree 100%.
Although local development of hypertext materials is still beyond a sizable
number of educators, there are many who are doing very creative and
constructive things with it....many more than who are prepared to work with
multimedia.  Very few have even heard of VR.  One promising aspect of
multimedia is its potential to initiate and support interdisciplinary
instruction.  I have a few clients beginning to try this, and they are
experiencing some success.

In conclusion, one of the problems I have with many of the discussions on
lists such as this is that the participants, myself included, generally tend
to speak of K-12 in global terms.  There is such enormous diversity within
K-12, and various socioeconomic, geographical and political sites that all
anyone can do is to keep looking for the selection of tools which best fit
the immediate situation.  Development of hypermedia, multimedia, VR, etc
is not providing more solutions, necessarily, but it is increasing the array
of tools from which practitioners can select.

Ren Bestebreurtje and others have asked me to clarify what I meant by soft-
system and non-system approaches to instructional design.  Must an ID model be
system based in order to be an ID model??  Steve Tripp, in ETRD, proposed a
Rapid Prototyping model for ID which is non-system based.  One reason it is not
a system based model (and he can jump in and correct me) is that it relies on
intuition and experience to make descisions.  One aspect of system theory is
phenomenal isomorphism (similarities between phenomena known through the
senses rather than through thought or intuition).  Also general systems theory
is concerned with the search for patterns of similarity regardless of the
the context or situation.  What about if we think that designing instruction
is different for K-12, Higher Ed, Military, etc, or for computers, VR,
multimedia etc or even for different age groups??    Soft-system approachs and
non-system approaches in my opinion allow  for intuition,"reflection-in-action"
and a move away from linear system based models.  I think the question is not
whether a ID model is systematic or systemic, rather what are the underlying
assumptions of system based models?  What are alternative views of designing
instruction.

I'm not fond of DOS backup/restore for a couple of reasons...the disks need
to be formatted before backup is done, and there is no compression, which
means more disks are used.   Of course, the price of disks allows this not
to be a real factor anymore.  Lastly, my complaint is that backup/restore
allows little means of recovery on problems.  The up side is that everyone
has DOS backup/restore, so moving files, like data files for seminars is
easily done.  The big reason that these programs are so average is because
Bill Gates indicated MS would not get into utility programs, and allow 3rd
party folks to do that.  However, seems MS DOS 6 (due out soon) will have
more of these utility programs built in....

just my 2 cents worth...
