Обновление делает Chronos task
Update frequency Description
Daily - Performed by the nightly "updall" task. If this nightly task is not run, the daily updating is not performed.
Scheduled - Performed by a Program Document that runs "updall". You must set the frequency to Scheduled and create the proper Program Document. You can also use this method to update different databases at different times.
Hourly - Triggered by the Chronos task and performed by the update task (if the update task is running). If not running, Chronos performs the update. If the Chronos task is not running, the update is not performed.
Immediate - Performed by the update task. If Update is not running, the update is not performed. All immediate requests are processed as they are received.
Deferred - Deferred requests are held for 15 minutes before they are processed. Requests to update the same database that occur in that time are ignored as duplicate requests.
