WriteReplicationFailOverMode Method

2008-12-15

后续版本的 Microsoft SQL Server 将删除该功能。请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The WriteReplicationFailOverMode method sets the failover mode for a subscription that uses immediate updating with queued updating as a failover option.

语法

object
.WriteReplicationFailOverMode(
szPublisher , 
szPublicationDB , 
szPublication ,
FailOverMode)

Parts

object
Expression that evaluates to an object in the Applies To list.

szPublisher
String that specifies the name of the Publisher.

szPublicationDB
String that specifies the name of the publication database.

szPublication
String that specifies the name of the publication.

FailOverMode
Long integer specifying a SQLDMO_REPLFAILOVER_TYPE constant as described in Settings.

Prototype (C/C++)

HRESULT WriteReplicationFailOverMode(
SQLDMO_LPCSTR pszPublisher, 
SQLDMO_LPCSTR pszPublicationDB, 
SQLDMO_LPCSTR pszPublication, 
SQLDMO_REPLFAILOVER_TYPE FailOverMode);

Settings

Set the FailOverMode parameter using these values.

Constant	Value	Description
SQLDMOReplFailOver_/Immediate	0	Use the immediate updating option to propagate changes made at Subscribers to the Publisher.
SQLDMOReplFailOver_/Queued	1	Use the queued updating option to propagate changes made at Subscribers to the Publisher.

备注

Microsoft SQL Server replication supports toggling between immediate updating and queued updating options. This configuration is also known as immediate updating with queued updating as a failover option. You can invoke failover, or queued updating, when an immediate update on the Subscriber fails because the Publisher is not available. At some later point, when the Publisher becomes available, you can invoke failback, or immediate updating. Set the FailOverMode parameter to SQLDMOReplFailOver_Queued to enable queued updating.

Prior to using WriteReplicationFailOverMode, ensure that the subscription was created using a SQLDMO_TRANSUBSCRIBER_TYPE value of SQLDMOTranSubscriber_Failover.

注意：
If an application calls WriteReplicationFailOverMode on 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.
