ADC Scheduling and Polling Intervals
The ADC uses a polling-based mechanism to request changes from the DS and AD. Each request for changes and any subsequent replication activity represent a synchronization cycle. In a two-way CA, the ADC typically first checks for changes in the DS, then in the AD. You can edit the CA's properties to change this default. As Figure 1 shows, you can configure replication to occur never, always, or at selected times. The ADC's Schedule tab resembles the Exchange 5.5 directory replication connector (DRC) Schedule tab. However, selecting Always for ADC replication configures the ADC to attempt synchronization every 5 minutes. (Selecting Always for DRC replication configures replication to occur every 15 minutes.)
When you configure replication to occur at selected times, you can specify 1-hour or 15-minute increments. The ADC begins polling at each time you select on the schedule grid. However, a cycle doesn't necessarily last for 1 hour or for 15 minutes; cycles run until they finish. If synchronization finishes in less than the specified time (i.e., 1 hour or 15 minutes), the ADC waits until the next selected time on the schedule to start another synchronization cycle. . . .
