Db component configuration creates database for the required webMethods components. You don’t have to run from the VM where webMethods is installed.
You can even run the db component configuration from your local /windows machine. If you have access to the database from the local.
Or as suggested by Holger , you may need to run dbConfigurator.sh (which doesn’t have UI).
