Notes

Using alternate Publishers provides an efficient mechanism for synchronizing a mobile Subscriber that is not connected to the Publisher with which it ordinarily synchronizes data changes. Subscribers can synchronize with any listed alternate Publisher as long as it publishes the exact data and schema required by the subscription.

Set the AllowSyncToAlternate property to TRUE to allow Subscribers to synchronize with an alternate Publisher. A Publisher can run the EnumAlternatePublishers method of a MergePublication2 object to obtain a list of enabled alternate Publishers and potential alternate Publishers. Subscribers can run the EnumAlternatePublishers method of a MergePullSubscription2 object to obtain a list of enabled alternate Publishers.

Use the AddAlternatePublisher method to add a server to a list of enabled alternate Publishers.

[!REMARQUE]

If an application calls AllowSyncToAlternate on an instance of Microsoft SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
