Acad2006 network license questions

Hi all,
we are thinking about switching most of our autocad standalone licenses to
network licenses when upgrading to 2006.
We have one main office where the license server(s) would be situated, and a
lot of "satellite" offices, each with 1-6 seats of autocad which would
request licenses via VPN, a total of ~160 licenses.

Q1: IT department is worried about network traffic and wants to know
_definitely_ how much data in which intervals will be sent.
In the Flexlm docs I found that checkout or checkin needs <1 KB of data
transferred, but nothing about heartbeat intervals.
So I guess heartbeat messages will need less or same amount of data, right?
Does anyone know exactly in which intervals heartbeat messages will be sent?
Is this configurable?

Q2:What happens if VPN connection breaks down for some reason? Is there any
possibility to define how long the client will keep its license after
loosing the connection to the server (whilst license is checked out on the
server of course)?
I read about the linger and timeout features in the options file but am not
sure if one of them is what I want and if it is supported by Autocad.

Thanks in advance for all answers.

A1. Not sure if this has changed in AutoCAD 2006 but I don't think so.

A2. What you might want to consider is a distributed server solution.

Thanks for your answer, Jimmy.

>A2. What you might want to consider is a distributed server solution.

Problem is, if VPN connection between main and satellite office breaks down,
it is normally due to any technical defect in the latter, so there is no
more connection to any of the other offices.
So far I can't see how to avoid loss of licenses with distributed servers,
except we would have one in each satellite office. Did you mean this?

Although I don't have any references I have been told that the "Heartbeat"
amounts to about the same data size as a Ping. IOW not much to worry about.
Although 160 pings per minute may add up to a slight amount of data being
transferred but I can't see it being significant.

Using a distributed setup you can set it up like this:
Main office - 100 licenses
Satelite 1 - 1 license
Satelite 2 - 5 license
Satelite 3 - 6 license
etc
In this case what happens when the connection goes down between Main office
and Satelite 2 is that Main office doesn't have access to the 5 licenses on
Satelite 2 and Satelite 2 doesn't have access to the Main offices licenses.

The user can point the licenses to the local location first and if it is not
find search a license on a second location and so on.

If all VPN's are up all users have access to all licenses.

1. I would have to install and maintain 25+ license servers. This wouldn't
save me much work compared to standalone licenses.
2. users frequently change from one office to another. To be correct I would
have to transfer the license, IOW getting 2 new license files every time a
user changes
3. AFAIK I would have to set an environment variable on each machine which
says "ask your local license server first, then all other 24 servers".
Everytime a user moves, I would have to change it on his machine. If one of
the servers is changed or gets a new ip adress, or if one office is closed
and another one is opened, ... i would have to change it on all. At least on
all servers, if we use a script which does the change on the clients.

I don't think this amount of distributed servers would be a good solution
for us.

Since VPN connections break down very rarely we only need a workaround for
the time until it is fixed.
I'm thinking of a scenario like this:
Everytime a user starts AutoCAD he gets a license from a server which is
granted for him for lets say the next 3 days. When he exits AutoCAD the
license "stays" at his machine. Worst case: when he starts AutoCAD again and
VPN is down, he gets the license as long as it is in the 3days-period.
Normal case: he starts AutoCAD again, VPN is up and the 3 days start again.

So we are back to my starting question, I'm still thinking about LINGER in
options file. Do you know if it can do the job?
Or is there a possibility for automatically borrowing the license for 3 days
everytime when the user starts AutoCAD?
Is there any possibility to borrow a license to a user after VPN went down?

Best regards,
Kathrin

Hi,

I don't know any way to automate borrowing of licenses in an easy way.
LINGER is not for that. One would think that lmborrow.exe or lmutil lmborrow
could be used but I've not been able to get it working.

Jimmy,
in which version of AutoCAD /FlexLM did you test this?

Is it an option for you to have a switch in each office with a dial-up
connection, and a RAS in the central office? This could be plugged in
when the VPN goes down? I guess that would be a pretty big modem bank
if you're planning for the case where the VPN goes down for all offices
at once...

Thanks for the idea. Of course an option to think about.
Question is, has the dial-up connection to be up all the time a user works
with autocad?
What if the connection is down and autocad sends a heartbeat -then it would
take some seconds till the connection is up -which time can autocad
tolerate?
And is it always the client which sends heartbeats and thus builds up the
connection, or does the server also need to build up a connection?

If VPN goes down for all offices at once, it could only be due to a
technical defect in the main office. In this case we would really have
bigger problems than not having autocad available in the satellite offices
;-) so we don't need to plan for that case
