Элементы

Имя элемента Описание
None Removes all options from Attributes.
AllowPush Subscriptions where the synchronization agent runs at the Distributor (push subscriptions) are supported.
AllowPull Subscriptions where the synchronization agent runs at the Subscriber (pull subscriptions) are supported. Required to support SQL Server Compact Subscribers.
AllowAnonymous Anonymous subscriptions can subscribe to the publication. Anonymous subscriptions are required if you want to create a subscription without registering the subscription at the Publisher. This is necessary for cases in which you cannot establish a SQL Server connection to the Publisher during subscription configuration.
InternetEnabled Publication can be synchronized over the Internet, and file transfer protocol (FTP) can be used to transfer the snapshot files to a Subscriber. For more information, see Репликация через Интернет.
ImmediateSync Synchronization files for the publication are recreated each time the Snapshot Agent runs. Subscribers are able to get the synchronization files immediately if the Snapshot Agent has completed before the subscription is created. New subscriptions get the newest synchronization files generated by the most recent execution of the Snapshot Agent. When setting ImmediateSync, IndependentAgent must also be set.
IndependentAgent Each subscription uses its own replication agent instance when synchronizing with the Publisher. Setting this option reduces latency and is the default for a transactional publication. Merge replication always uses independent agents.
SnapshotInDefaultFolder The snapshot files for the publication are maintained in the default folder. When SnapshotInDefaultFolder is not specified, you must specify an alternate location for the snapshot files using AltSnapshotFolder.
CompressSnapshot Snapshot files are compressed into the CAB format. Snapshot files that are larger than 2 gigabytes (GB) cannot be compressed. Not supported for SQL Server Compact Subscribers.
AllowSubscriptionCopy Databases that subscribe to the publication can be copied and attached to create new subscriptions. Attachable subscriptions have been deprecated.
AllowSynchronousTransactions Immediate updating subscriptions are supported for transactional publications. Supported only for transactional publications.
AutomaticGenerateSyncProcedures The stored procedure used by updating subscriptions to synchronize with the transactional publication is automatically generated. Supported only for transactional publications.
CentralizedConflicts Conflict records are stored at the Publisher. Supported only for merge publications.
EnabledForActiveDirectory The attribute is EnabledForActiveDirectory.
AllowQueuedTransactions Queued updating subscriptions are supported for transactional publications. Supported only for transactional publications.
AllowDtsTransformation В будущей версии Microsoft SQL Server этот компонент будет удален. Не используйте его при работе над новыми приложениями и как можно быстрее измените приложения, в которых он в настоящее время используется.
DynamicFilters Parameterized row filters are supported on a merge publication. Supported only for a merge publication.
KeepPartitionChanges Partition change optimizations are used when precomputed partitions cannot be used. Do not specify KeepPartitionChanges when PartitionGroupsOption is True. For more information, see Оптимизация производительности параметризованного фильтра с помощью предварительно вычисляемых секций.
AllowSyncToAlternate Subscribers can synchronize subscriptions to the merge publication with servers other than the Publisher where the subscription originated. Supported only for merge publications. This feature is deprecated and will be removed in a future release. Not supported for SQL Server Compact Subscribers.
AllowSubscriberInitiatedSnapshot Subscribers can initiate the snapshot process to generate the filtered snapshot for their data partition when the merge publication has parameterized filters. Supported only for merge publications.
AllowWebSynchronization Subscribers can synchronize subscriptions over the Internet using the HTTPS protocol. Supported only for merge publications. Only available with SQL Server 2005. Required to support SQL Server Compact Subscribers. For more information, see Веб-синхронизация для репликации слиянием.
AllowInitializationFromBackup Subscribers can initialize a subscription to the publication from a backup rather than the initial snapshot. Supported only for transactional or snapshot replication.
EnabledForPeerToPeer Peer-to-peer transactional replication is supported. Supported only for transactional publications. Only available with SQL Server 2005 and later versions.

When setting EnabledForPeerToPeer, the following restrictions apply:

  • Type must be set to Transactional.

  • ConflictPolicy must be nullпустая ссылка (Nothing в Visual Basic).

  • The following options must be set:

    • AllowInitializationFromBackup

    • IndependentAgent

  • The following options cannot be set:

    • AllowAnonymous

    • AllowDtsTransformation

    • AllowQueuedTransactions

    • AllowSynchronousTransactions
AllowPartitionRealignment Deletes are sent to the Subscriber when modification of the row on the Publisher causes it to change its partition and when the publication uses parameterized filters. Supported only for merge publications.
ПримечаниеПримечание

If this attribute is not enabled, data from an old partition remains on the Subscriber. Changes made to this data on the Publisher will not replicate to this Subscriber, but changes made on the Subscriber will replicate to the Publisher. Therefore, you should treat data from an old partition as read-only data.
DecentralizedConflicts Conflict records are stored at the Subscriber. Supported only for merge publications. Not supported for SQL Server Compact Subscribers.
EnabledForHeterogeneousSubscribers Non- SQL Server Subscribers are supported. Supported only for transactional and snapshot publications. Only available with SQL Server 2005 and later versions.

When setting EnabledForHeterogeneousSubscribers, the following restrictions apply:

Замечания

The PublicationAttributes enumeration supports the FlagsAttribute option, which allows a bitwise combination of enumeration values.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.
