Changing Settings that Require a Restart

This chapter discusses the difference between Traffic Manager software restarts and full host reboots.

Software Restarts

The Configuration Importer automatically restarts the Traffic Manager software on all cluster members if a changed configuration setting requires a restart to take effect.

In some circumstances, you might want to disable this behavior and delay restarts to happen at a later time, such as during a maintenance window. To disable automatic restarting of the software, supply the "--no-restart" argument to the "config-import" tool, or add "--no-restart" to the ZEUS_CONFIG_IMPORT_ARGS environment variable when launching a Docker container. By using this argument, you must manually restart your Traffic Managers at the appropriate time for pending changes to take effect.

Host Instance Reboots

Some configuration changes might require a full host instance reboot to take effect. This is not an automatic process and must be performed manually on all cluster members. Ivanti recommends you schedule a full reboot to take place at a time of least impact to your services.
