ComputeService.config.json is the global configuration file for the Simulation Compute Manager services. It includes environments, monikers, service parameters, urls, and service definitions. Global service parameters apply to all services. Service parameters defined within a service definition define the parameter for only that service.
Simulation Compute Manager environment variables override service parameters.
For Insight Linux Thinclient installs the user must set the environment variables and then restart the daemon manually.
Environment variables for Insight Linux Workstation installations, in which SCM is running as a systemctl managed service, must have environment variables set so that they are visible to the service. This can be done with either of the methods below.
Editing the /usr/lib/systemd/system/adskscm.service file directly.
Editing the service with the systemctl edit command.
