Howto: How to license and configure a DELTAGEN R2019x Distributed Stellar cluster

Solution

The Distributed Stellar cluster license is only available as Dassault Systems License System (DSLS) license. If you are still using the older FlexLM licensing mechanism (e.g. for DELTAGEN) you will additionally need to install a DSLS license server. Both systems can work in parallel on the same server and it is not necessary to migrate all existing licenses to the DSLS.

The following steps are oriented on a generic example:

1. If not already existing, install a new DSLS license server which is reachable by your cluster nodes:
   The server software and the documentation is available on the DS website: https://www.3ds.com/support/documentation/resource-library/single/dassault-systemes-license-server-and-license-keys/ .
   Download the software, and execute the installation. See the “DSLS Installation and Configuration Guide” for further operating systems and installation details.
   Additional information: In our example, we installed the DSLS license server and the administation tool on the same machine.Step Result: Usually, the DSLS license server administration tool gets started automatically after the server went online.
2. Forward the Computer-ID (available in the main tab of the administration tool) to your DS Sales representative.
   She/He will then order the Distributed Stellar licenses for you.Step Result: You will receive one or more .LICZ files which represent the DSLS license(s) for your Stellar cluster.
3. Open your DSLS license administration tool, click on License -> Register, and load the .LICZ file(s) you received.Step Result: Your licenses will now be installed on the DSLS license server.
4. Connect your render nodes to your DSLS license server:
   On Windows, on each client computer, create the following directory:
   C:\ProgramData\DassaultSystemes\Licenses
   On Linux, create the following directory:
   /var/DassaultSystemes/Licenses
   In that directory, create a .txt file named DSLicSrv.txt.
   Inside that text file, specify the license server host name and the port the server is listening on:
   servername:portnumberResult: Your Distributed Stellar cluster should now work. Connect your DELTAGEN with your Distributed Stellar cluster as you are used to.
