MATLAB: Combining Windows and Linux license managers

.mcombinelicenselinuxwindows

Is it possible to run Linux and Windows network clients from one single Windows license manager, rather than having separate Linux and Windows license managers for each? If so, are there any restrictions (e.g. same version for network clients, etc)

Best Answer

As far as we know, FLEXlm that is the license manager implemented by Mathworks allows this with no limitation. You can use network license served by your Windows license manager from any operation system running the client software.

MATLAB: How to change the activation of a MATLAB installation from Individual or Designated Computer to Concurrent

Before MATLAB clients are able to check out a license key from the license server with the Network Concurrent license, make sure that the License Manager is installed. Please see here for instructions:

How do I install or update the Network License Manager?

https://www.mathworks.com/matlabcentral/answers/105860

Once the License Manager is installed, copy the license.dat from the server (by default located in $MATLABROOT/etc, e.g. C:\Program Files\MATLAB\R2019b\etc) to a folder on the clients.

Deactivate MATLAB:

As a next step, remove the old license activation from the MATLAB installations. For instructions, see the following article:

How do I deactivate MATLAB?

https://www.mathworks.com/matlabcentral/answers/100663

Re-activate MATLAB:

After the deactivation is complete, launch MATLAB. It will ask for a new activation. In the Activation programme, select ‘Activate manually without Internet’. Proceed with the steps. When prompted for the license file, point to the license.dat file. MATLAB should now use the Network Concurrent license.

MATLAB: How to serve multiple MATLAB licenses from the same network license manager

To serve multiple MATLAB licenses from the same network license manager, you need to activate both licenses to the server’s host ID and combine the contents of the license file into the same file.

Start by activating and installing one of your licenses on the server in question. The MATLAB installer will not accept a combined license file so you need to install the license manager using license file containing a single license. Instructions for this procedure can be found in How do I install or update the Network License Manager?

Once the license manager is running for one license, repeat the activation procedure (but not the installation procedure) for the second license. Once you have the license file for the second license, stop the license manager and open the license.dat file. By default, the license.dat file is located in the MATLAB installation directory.

Windows:

C:\Program Files\MATLAB\R20XXx\etc\license.dat

Linux:

/usr/local/MATLAB/R20XXx/etc/license.dat

Using a plain text editor, copy the contents of the license.lic file you downloaded from the MathWorks License Center for the second license into the bottom of the license.dat file on the server. Save the file. Repeat this procedure as necessary to add additional licenses.

Concurrent and NNU licenses

The most common scenario for separating two groups of users is serving a Network Concurrent and a Network Named User license from the same server. Please see How do I combine a Network Named User license with a Concurrent license on the same license server? for specific instructions on this setup.

Global Concurrent and Local Concurrent Licenses

If you choose to serve a local concurrent and global concurrent license from the same server, the local license must only be accessed by the users in the specified country.

To restrict usage of the license to users in the appropriate country, create an options file with user groups for each country, and then use asset_info tags to direct users to the appropriate license.

Please contact MathWorks support if you require assistance with separating the users of a Global Concurrent and Local Concurrent Licenses.
