AltSnapshotFolder Property

Questa caratteristica verrà rimossa a partire da una delle prossime versioni di Microsoft SQL Server. Evitare di utilizzare questa funzionalità in un nuovo progetto di sviluppo e prevedere interventi di modifica nelle applicazioni in cui è attualmente implementata.

The AltSnapshotFolder property specifies an alternate path to use for snapshot file creation or application.

HRESULT SetAltSnapshotFolder(SQLDMO_LPCSTR NewValue);

Osservazioni

If used with the MergePublication2 or TransPublication2 objects, the AltSnapshotFolder property specifies an alternate location to use for snapshot file creation when a snapshot must be transported to a Subscriber. If used with the MergePullSubscription2 or TransPullSubscription2 objects, AltSnapshotFolder specifies an alternate location to use for snapshot file application.

Transporting a snapshot file using portable media, such as a removable hard drive, can be useful in situations where a Subscriber is not continuously connected. Transporting a snapshot file may also be desirable in a situation where a large amount of data might otherwise need to be applied using an expensive connection.

AltSnapshotFolder is required if the publication attribute SQLDMOPubAttrib_InternetEnabled is set.

[!NOTA]

If an application sets AltSnapshotFolder with the MergePublication2 or TransPublication2 object after the initial snapshot has been created, a new snapshot must be generated. Snapshots are applied when the next scheduled snapshot agent runs.

[!NOTA]

If an application calls AltSnapshotFolder 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.
