Sets the maximum number of stations that can be active when the cleanup of the GLB-DIALOGINFO is initiated by the :DCS command. This command relates to the GLB-DIALOGINFO dataset.

The cleanup does not proceed if the number of stations exceed the threshold specified by the :DCA command, despite the machine clock showing the hour specified by the :DCS command. If the threshold is not met within the hour specified by the :DCS command the cleanup is performed later. The purpose of using a threshold is to trigger the cleanup when the least number of stations are active within the hour specified for the cleanup.

Refer to DCS DIALOGINFO Cleanup Start for more information on scheduled cleanup.

By default, the setting is 0. The maximum setting is 99. When the :DCA is set to 0, it disables the threshold check at cleanup time; that is, it indicates no limitation. Security level is Controller.

The :DCA command has the form:

:DCA [number]

Where

number is the maximum number of stations that can be active at the time of cleanup.

The setting of :DCA is retained in the database. If no parameter is specified the current threshold is displayed.
