How do I use a startup parameter?

Startup parameters only work if the server is using the Custom JAR server type.
The custom JAR file must be named the default name, custom.jar, in order for the startup parameters to appear.
It is not currently possible to use custom startup parameters - only predefined ones can be used. Please contact us if you think there is one that should be added.

Stop your server.

Navigate to the Advanced>Startup Parameters tab of the panel.

Check the box next to the startup parameter you wish to use.

The startup parameter has now been enabled and will take effect on the next server start.

Start the server.
