   Parameter	Description
   Send Notifications	SMN topic. This parameter is optional. If an exception occurs during synchronization, the system will send a notification to the specified recipients.
   SMN Topic	This parameter is available only after you enable Send Notifications and create a topic on the SMN console and add a subscriber. For details, see Simple Message Notification User Guide.
   Synchronization delay threshold	A synchronization delay indicates a time difference (in seconds) of synchronization between the source and destination database. If the synchronization delay exceeds the threshold you specify, DRS will send alarms to the specified recipients. The value ranges from 0 to 3,600. To avoid repeated alarms caused by the fluctuation of delay, an alarm is sent only after the delay has exceeded the threshold for six minutes. NOTE: Before setting the delay threshold, enable Send Notification. If the delay threshold is set to 0, no notifications will be sent to the recipient.

4. After the task is submitted, view and manage it on the Data Subscription Management page.
   • You can view the task status. For details, see Task Statuses.
   • You can click in the upper-right corner to view the latest task status.
   

   After a subscription task is created, you can use an SDK to subscribe to incremental data in the subscription task in real time. For details, see SDK Operation Instructions.
