备注
You cannot use MulticastDelivery with Microsoft SQL Server Standard Edition.
Multicast delivery conserves formatting and distribution resources by formatting and distributing identical notifications for multiple subscribers. A common use of multicast delivery is when many users will receive the same notification, such as for sports scores, and the notifications use the same locale and delivery device. Instead of formatting and sending the same message 50 times, Notification Services formats a single notification, determines the subscriber list, and then passes the array of subscribers to the delivery protocol.
If using multicast delivery, you should not include subscriber-specific information in your notifications.
You can limit the number of recipients in each multicast group with the MulticastRecipientLimit Element (ADF).
You cannot use both multicast delivery and digest delivery. If using multicast delivery, the DigestDelivery value must be false.
示例
