ecFlow server environment variables control the execution of ecFlow and may be set before the start of the server, typically in a start-up script.
ecFlow will start happily without any of these variables being set since all of them have a default value. These default values can be overridden by:

• Setting them in "server_environment.config". This file should then be placed in the current working directory when invoking the server.
• Explicitly setting environment variables. These will override any setting in the "server_environment.config" file.

For the full list of environment variables used the server please see 'ecflow_server' in the Glossary.
