Network Planning Concepts 2

• Since the redundant server model is more
susceptible to network failure, all servers must
reside on the same subnet and have consistent
network communications. All servers must be
located on the same site.
• Slow, erratic, or dial-up connections are not
recommended when using the redundant server
model.
• The redundant server model does not support the
UDP packet type.
To create a redundant server pool, run the AdLM
installation on the initial server you want to
configure, then repeat the AdLM installation for the
other two servers. To get proper license
authorization, you must obtain the Host ID and
server name for each server in the redundant server
pool before contacting Autodesk. For additional
information, see
“Obtaining the Server Host Name
and ID” in Chapter 4, “License Server
Configuration’’
.
Once all client workstations are installed and
communicating with the license server, you must
modify the
combustion.lic file on each client
workstation to include server information for each
of the three servers. Following is an example of the
contents of the
combustion.lic file:
SERVER PC54321 210987654321
USE_SERVER
Following is an example of a combustion.lic file
modified for a redundant server operation:
SERVER PC54321 210987654321 27005
SERVER PC12345 123456789012 27005
SERVER PC32154 321543210981 27005
USE_SERVER
The redundant server model requires a port number
(the default is 27005) for each server.
The port number at the end of each SERVER line
must also be included in the license file for the
redundant server model only.
The redundant server model requires Windows
2000 Server Edition.
Note: Windows 2000 Workstation edition is not
supported as license servers.
The redundant server model also requires that
separate copies of the same license file, license
manager daemon (lmgrd), and vendor daemon
reside on each server; all are necessary to
authenticate and release licenses.
If the redundant server configuration fails, it might
be necessary for the system administrator to start
the license server on each of the redundant server
machines within a few minutes of one another.
AdLM Network Communication
Protocol
Once you have chosen your preferred installation
configuration, you have the option of using either
the TCP/IP or UDP packet types. The AdLM uses
the standard network protocol—Transport Control
Protocol/Internet Protocol (TCP/IP) packets by
default. TCP sends data between applications
whereas IP communicates data between an
application and the physical network.
There is a 10-connection TCP/IP limit with
Windows 2000/Windows XP Professional editions.
The Windows 2000 and Windows XP Server
editions do not have the 10-connection limitation,
so they are the preferred Operating systems. If you
have more than 10 client workstations that need to
access a single license server and you do not have a
Server edition of Windows, then use UDP as the
default packet type. UDP requires more extensive
configuration at servers and clients.
