Server Configuration Variables

Server configuration variables are stored in the database and can be modified at runtime without restarting the server (unless noted otherwise with *). They control server behavior, polling intervals, security settings, and feature toggles.

Use the management client (Configuration > Server Configuration) to view and modify variables, or nxdbmgr from the command line:

nxdbmgr set VariableName value

For operational guidance, see Server Configuration.

Variables marked with * require a server restart after modification. All other variables take effect immediately.
