Overview

Floating licenses allow a group of users to share T-VEC licenses on a network. The licenses are managed by a license manager which limits the number of concurrent users of the tools to the number of licenses specified in a license file. T-VEC tools use the the FlexLM license manager to manage licenses.

In a FlexLM floating configuration, the T-VEC tools communicate with the FlexLM license manager to obtain licenses. The machine running the FlexLM license manager is referred to as the license server.

There are three components of the license manager:

  • FlexLM license manager (lmgrd)
  • License File
  • T-VEC license (vendor) daemon (tveclmd)

On Windows, the FlexLM license manager, lmgrd, typically runs as a service and starts as part of Windows startup. lmgrd reads the license file associated with it and loads any vendor daemons specified in the license file. The T-VEC license vendor daemon is tveclmd. Once tveclmd is started by lmgrd, it manages the licenses for T-VEC tools.

The License File

A typical license for T-VEC tools looks like the following example.

SERVER license_server 00a02471cf70 TCP: 27007
DAEMON tveclmd c:\t-vec\license\tveclmd.exe

In this example, the license server is named "license_server". The server's ethernet address is "00a02471cf70". The license manager listens on port 27007 for client license requests. The vendor daemon for managing the license requests is tveclmd.exe. The information following the first two lines of the license file contain details on the licenses managed by this file.

The server name, port and path to the vendor daemon can be updated without invalidating the license file. It is good practice to use the full path to specify the vendor daemon.

SERVER [server] 00a02471cf70 TCP: [port]
DAEMON tveclmd [path to vendor daemon]

Installing and Configuring the License Manager

The files necessary to install and configure the license manager are included in the "license" directory of the T-VEC installation. These files include:

  • lmgrd - FlexLM license manager
  • tveclmd - T-VEC vendor daesom
  • lmtools - Utility for configuring the license manager (GUI)
  • lmutil - Command-line utility for configuring the license manager

It is possible to download and use the latest versions of the FlexLM software. Distribution of FlexLM has been handled by a couple different companies. A google search is probably most effective for finding the latest downloads. Find the Latest FlexLM

While the license manager can be configured in the T-VEC license directory, the default location for FlexLM license manager installations is c:\flexlm.

Obtain a License File

In addition to these files, a valid license file for the T-VEC tools is required to complete the setup. License files are obtained from T-VEC support. They are generated based on the license server's hostid which is typically it's ethernet (MAC) address. Send the server name and ethernet address to T-VEC Support to obtain a license file. See License_Management#Obtaining_Licenses for information on obtaining a license file for the license server.

Configuration through LMTools

The lmtools application which is included in the license directory of the T-VEC installation is the easiest way to configure the license manager. Start the license manager by double-clicking it (lmtools.exe).

To specify a new license manager service, click the "Config Services" tab. Specify a name of the new license manager service. Next specify the locations of

  • lmgrd.exe
  • license file (usually license.dat)
  • log file location

See the image before for examples.

Enable the "Use Services" and "Start Server on Power Up" to have the license manager start automatically. Finally, click the "Save Service" button to apply the settings.

Starting the License Manager Service

To start the new license, click on the "Start/Stop/Reread" tab. Select the service from the list of services displayed, and then click the "Start Server" button.
