Answer:
Hi Rachid-

The demo license practice has changed with the FLEX implementation. Now SYNERGY demo licenses will be more consistent with the other products. Demo licenses will be made available that will work on any host and will expire on a given date.

UNIX Installations Need license_data.txt Set

In previous releases, the license key data was kept in a file to be read by the SYNERGY/CM license daemon process (ccm_lmgr). This file was named "$CCM_HOME/etc/license_data".

In 6.4, this has changed. The SYNERGY/CM license daemon has been replaced with FLEXnet (previous known as FLEXlm). The FLEXnet license daemon is independent of SYNERGY/CM and can serve licenses for other Telelogic products as well as for products from other software vendors. What this means is that the license key file is now kept outside the SYNERGY/CM installation area. Its location is at the discretion of the FLEXnet configuration. The FLEXnet files required to run SYNERGY/CM and other Telelogic products will be installed separately. The instructions on how to set up the FLEXnet license daemon will be provided by the Tau lab which is supporting the Telelogic vendor daemon portion of the FLEXnet server. The license server should be installed and configured prior to installing SYNERGY/CM so that it may be accessed immediately upon completion of the SYNERGY/CM installation. The FLEXnet servers may run on the same host as SYNERGY/CM or upon a different host. The platform of the host running FLEXnet is independent of the platform which hosts SYNERGY/CM.

SYNERGY/CM will need to know the location of the FLEXlm server. The location data will be kept in the file "$CCM_HOME/etc/license_data.txt". Note that this file does not contain the actual license key data, but instead, it contains the location of the license key file or the address of the FLEXnet server. The contents of license_data.txt is a single line of data which contains a list of locations. Each location is separated by a colon (":") on UNIX and a semicolon (";") on Windows. Each location is either a fully qualified path to the license key file or the address of the FLEXnet server in the form @. The port number may be left off if the port is in FLEXnet's default range of 27000-27009. This syntax is the same as the value of the VENDOR_LICENSE_ FILE value described in the FLEXnet end user's documentation.

Example contents of license_data.txt:

19353@licserver:/usr/local/flexlm/license.dat

The $CCM_HOME/etc/license_data.txt file is read by the router daemon when it is started. If the contents of the license_data.txt file are changed, the router must be restarted before the change will take effect.

Hi,

we used to set DEMO in the license files in previous version. Is there still a way to use demo licenses in CM6.4?

This procedure also worked for Windows. I installed SYNERGY/CM 6.4 beta first and after that the License Manager that I used for DOORS 7.1.
Changing the text in license_data.txt to 19353::C:\

where of course and were personal worked fine. I did not choose a path with spaces in it though to be on the safe side.

Cheers,

Jaap Mulder

In my last mail the characters the sentence was mangled by the HTML server that read the input. The line should have been:

19353@"myservername":"mylocation"

Because of security reasons the Flexnet lmgrd should not be started as root!

If you start lmgrd as ccm_root you don't need to have the $CCM_HOME/etc/license_data.txt file in place.

For a good and consistent usage style we shall rather have a file called $CCM_HOME/etc/lmgr.cfg instead of license_data.txt

A manual or release notes shall have all the hints and tricks for using FlexLM with SYNERGY, especially since this is new to most customers!
