Subject:      How big is big? (PC lan, MS Windows, 500 users?) (Q)


Pardon a possibly dumb question; I've been reading for a while and this
appears the place to ask:  is a 500-PC lan running word processing (MS
Word for Windows, probably) within the currently reliable state of the art?

[Or are the people I work with being set up for a big fall ...?]

Subject:      Connecting and IBM9121 to the network (Q)

Hi,

I need to connect an IBM 9121-320 running native MVS/ESA to a  TCP/IP
network.  A segment of the network  is actually X.25 and TCP/IP being
encapsulated over it, so I can also look into solutions that might
use X.25.

Some facts (??) I've gathered asking around: TCP/IP on an MVS system
is very slow and resource consuming.  One solution is running also
MPSI (X.25 for MVS?) and a 3745 Comm. Cont. connecting to an X.25
switch.

Another is using a 3172 LAN Adapter  and connecting to a multiprotocol
router using token ring or ethernet.

As you can see both  solutions are basically IBM solutions.

Does anyone have any other ideas?  Maybe using some 3rd party products?
I'll appreciate any suggestions.

Thanks.

Subject:     We have many classrooms for computer educations.

We have many classrooms for computer educations.
Many students studying about computer can use them as a tool for a
research and study.
There are about 130 workstations and 170 lap-top computers and 41 per-
sonal computers in our two campus.(last pc is used for CAD(computer
aided design))
All machines are connected by coaxical cable to mainframe.
Then all machines have two functions, one is online-function as using
mainframe, other is offline function that means they use an independen
ce function of personal computer (stand-alone function).
So all students even use only a function of personal computer keep to
connect to mainframe.Because we identify user-id and password by main-
frame.I always think our computer environment make mainframe very very
busy.So we want to make another type of classroom, at next time to
make new classrooms we will intoroduce NETWARE for identifing users
want to use only a stand-alone function.
But someone teach me that one sever machine installed NENETWARE can't
manage over 250 users at once. So I suppose we should have several
servers.On the other hand, in this case if servers don't join hands
with others, some user can connect to plural server machines at once.
Because they don't know he have always connected to other machines.

How do we manage such a case ?
We will have to set up main-server machine for each servers,won't we.

Finally why I am particular about connection at once is that we want
to use this system to submit reprots or answers of students, so they
might submit two reports or answers to different server machines.
Then this case might make us confuse ||
Do you understand my question ?

Please tell me a good way to use NETWARE.

At last I'm not good at write in English,so perhaps there are many
mistakes. Please teach about my mistake |

 For example:at above case, user1(u1) can also connect to server1 and
             server2. So he can submit his reports into server1 and se
             ver2. Because server1 and server2 don't know he has
             already submitted to another server.
             We will be confused||
             Can we set up main-server for server1 - server3 and can
             main-server manage each servers ?
  Do you understand I would like to mean and my question ?

Subject:      LAN 'wellness'

I'm working on LAN strategies and guidelines and would be interested in
hearing what metrics people are using to determine the 'wellness' of their
LAN(s). Do you go by utilization? Response? Latency? Other?

                                                Regards,

                                                Thom Langlois...
