DTSPackageLocation Property
В будущей версии Microsoft SQL Server эта возможность будет удалена. Избегайте использования этой возможности в новых разработках и запланируйте изменение существующих приложений, в которых она применяется.
The DTSPackageLocation property specifies the location of a Data Transformation Services (DTS) package to be used during a replication process.

Description |
---|---|---|
SQLDMOReplDTSPackageLocation_/Distributor |
0 |
The DTS package is located at the Distributor. |
SQLDMOReplDTSPackageLocation_/Subscriber |
1 |
The DTS package is located at the Subscriber |
Замечания
For push subscriptions, a DTS package used during the replication process is located at the Distributor by default. Specify a SQLDMO_REPLDTSLOC_TYPE setting of SQLDMOReplDTSPackageLocation_/Subscriber to specify to Distribution Agent that the DTS package is located at the Subscriber.
For pull subscriptions, a DTS package used during a replication process is located at the Subscriber by default. Specify a SQLDMO_REPLDTSLOC_TYPE setting of SQLDMOReplDTSPackageLocation_/Distributor to specify to Distribution Agent that the DTS package is located at the Distributor.
The complexity and quantity of transformations performed by a DTS package may significantly affect performance at the Distributor or Subscriber, especially during periods of heavy processing. Additionally, data transformation requirements may vary at different subscribing locations. Use the DTSPackageLocation and the AgentOffload properties to reduce the network traffic. For example, in the case of a push subscription, Distribution Agent runs at the Distributor by default. If the DTS package is located at the Subscriber, Distribution Agent must run package instructions over a network connection. However, if Distribution Agent execution is offloaded to the Subscriber, the agent runs package steps at the Subscriber.

If an application calls DTSPackageLocationon an instance of 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. |
