Creating a Vacuum Schedule

A vacuum schedule named StockWatchVacuumSchedule is created in the CreateVacuumSchedule( ) method of Example 18-1. The code follows:

private static void CreateVacuumSchedule( )
{
  VacuumSchedule vs = new VacuumSchedule
    (a, "StockWatchVacuumSchedule");
  vs.StartTime = new TimeSpan(0, 0, 0);
  a.VacuumSchedules.Add(vs);
  Console.WriteLine("Added vacuum schedule: " + 
    vs.Name);
}

Vacuuming removes old event and notification data from the application database on a daily schedule. The StartTime property specifies the daily time in Universal Coordinated Time (UTC) for the data removal process to start. Although specifying a vacuum schedule is optional, old data is not removed from the database if a vacuum schedule is not specified.

The NMO classes for managing vacuum schedules are described in Table 18-12.
