Start-up Suppress Alarm Period

When the server starts up there is a lot of activity related to the database, which would cause Lock Usage alarm thresholds to be exceeded and alarms generated. Use this field to define a period at start-up when these alarms are suppressed. The default setting is 15 minutes.

Area of Interest

This field is only displayed if the Area of Interest feature is enabled on your system. Use the field to specify the Area of Interest with which the item's alarms and events are to be associated (see Assign a Different Area of Interest to an Item's Alarms and Events). For further information about the Area of Interest feature, see Restrict Alarm and Event Access to Specific Areas of Interest.

In addition to an alarm appearing in the Alarm Banner a warning appears in the Server Status General Information window, see General Status - Information.
