When do changes to MID Server parameters take effect?

Changes to MID Server parameters are effective when the MID Server is started or restarted. This means that any adjustments made to the configuration settings require the MID Server to be restarted in order to apply the new settings. During the startup process, the MID Server reads the configuration parameters and initializes its operations according to the updated values.

This behavior emphasizes the importance of proper planning and timing when modifying MID Server configurations. If settings are altered, those changes will not influence the MID Server's functionality until it is initiated again, ensuring that previous configurations do not unintentionally interfere with the new settings until a restart occurs.

The other options do not accurately represent the functionality associated with MID Server configuration changes. For example, immediately upon saving would imply that changes take effect instantly, which is not the case. Likewise, user login or a set time delay of an hour do not pertain to the mechanism of how the MID Server processes parameter updates. Only a restart guarantees that the MID Server operates with the latest definitions.
