DTSPackageLocation Property
Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement et prévoyez de modifier les applications qui utilisent actuellement cette fonctionnalité.
The DTSPackageLocation property specifies the location of a Data Transformation Services (DTS) package to be used during a replication process.
Syntaxe
object.DTSPackageLocation [= value]
Parts
object
An expression that evaluates to an object in the Applies To list.value
A long integer that specifies a SQLDMO_REPLDTSLOC_TYPE constant as described in Settings.
Data Type
Long integer
Modifiable
Read/write
Prototype (C/C++)
HRESULT GetDTSPackageLocation(
SQLDMO_REPLDTSLOC_TYPE pRetVal);
HRESULT SetDTSPackageLocation(
SQLDMO_REPLDTSLOC_TYPE NewValue);
Settings
Set the DTSPackageLocationproperty using these values.
Constant |
Value |
Description |
|---|---|---|
SQLDMOReplDTSPackageLocation_/Distributor |
0 |
The DTS package is located at the Distributor. |
SQLDMOReplDTSPackageLocation_/Subscriber |
1 |
The DTS package is located at the Subscriber |
Notes
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.
[!REMARQUE]
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.
