同步请求订阅

适用于SQL Server Azure SQL 托管实例

本主题说明如何使用 SQL Server Management Studio、复制代理或复制管理对象 (RMO) 在 SQL Server 中同步请求订阅。

本主题内容

使用 SQL Server Management Studio

订阅由分发代理(对于快照复制和事务复制)或合并代理(对于合并复制)进行同步。 代理可以连续运行、按需运行或按计划运行。 有关如何指定同步计划的详细信息,请参阅指定同步计划

在 SQL Server Management Studio 中的“本地订阅”文件夹中,按需同步订阅。

在 Management Studio 中按需同步请求订阅

  1. 在 Management Studio 中连接到订阅服务器,然后展开服务器节点。

  2. 展开 “复制” 文件夹,再展开 “本地订阅” 文件夹。

  3. 右键单击要同步的订阅,然后单击 “查看同步状态”

  4. 在“查看同步状态 - <订阅服务器>:<订阅数据库>”对话框中,单击“启动”。 完成同步后,将显示消息 “同步完成”

  5. 单击“关闭” 。

复制代理

可通过在命令提示符下调用相应的复制代理可执行文件,以编程方式按需同步请求订阅。 被调用的复制代理可执行文件将取决于请求订阅所属的发布的类型。 有关详细信息,请参阅 Replication Agents

注意

复制代理使用通过命令提示符启动该代理的用户的 Windows 身份验证凭据连接到本地服务器。 这些 Windows 凭据还在使用 Windows 集成身份验证连接到远程服务器时使用。

通过命令提示符或批处理文件启动分发代理

  1. 在命令提示符下或批处理文件中,通过运行 distrib.exe 并指定下列命令行参数来启动 复制分发代理

    • -Publisher

    • -PublisherDB

    • -Distributor

    • -DistributorSecurityMode = 1

    • -Subscriber

    • -SubscriberDB

    • -SubscriberSecurityMode = 1

    • -SubscriptionType = 1

    如果您使用的是 SQL Server 身份验证,则还必须指定下列参数:

    • -DistributorLogin

    • -DistributorPassword

    • -DistributorSecurityMode = \@publisher_security_mode

    • -PublisherLogin

    • -PublisherPassword

    • -PublisherSecurityMode = \@publisher_security_mode

    • -SubscriberLogin

    • -SubscriberPassword

    • -SubscriberSecurityMode = 0

在命令提示符下或批处理文件中启动合并代理

  1. 在命令提示符下或批处理文件中,通过运行 replmerg.exe 并指定下列命令行参数来启动 复制合并代理

    • -Publisher

    • -PublisherDB

    • -PublisherSecurityMode = 1

    • -Publication

    • -Distributor

    • -DistributorSecurityMode = 1

    • -Subscriber

    • -SubscriberSecurityMode = 1

    • -SubscriberDB

    • -SubscriptionType = 1

    如果您使用的是 SQL Server 身份验证,则还必须指定下列参数:

    • -DistributorLogin

    • -DistributorPassword

    • -DistributorSecurityMode = \@publisher_security_mode

    • -PublisherLogin

    • -PublisherPassword

    • -PublisherSecurityMode = \@publisher_security_mode

    • -SubscriberLogin

    • -SubscriberPassword

    • -SubscriberSecurityMode = 0

示例(复制代理)

以下示例启动分发代理以同步请求订阅。 所有连接均使用 Windows 身份验证实现。

 -- Declare the variables.  
SET Publisher=%instancename%  
SET Subscriber=%instancename%  
SET PublicationDB=AdventureWorks  
SET SubscriptionDB=AdventureWorksReplica   
SET Publication=AdvWorksProductsTran  
  
-- Start the Distribution Agent.  
-- The following command must be supplied without line breaks.  
"C:\Program Files\Microsoft SQL Server\100\COM\DISTRIB.EXE" -Subscriber %Subscriber%   
-SubscriberDB %SubscriptionDB% -SubscriberSecurityMode 1 -Publication %Publication%   
-Publisher %Publisher% -PublisherDB %PublicationDB% -Distributor %Publisher%   
-DistributorSecurityMode 1 -Continuous -SubscriptionType 1;  

以下示例启动合并代理以同步请求订阅。 所有连接均使用 Windows 身份验证实现。

-- Declare the variables.  
SET Publisher=%instancename%  
SET Subscriber=%instancename%  
SET PublicationDB=AdventureWorks  
SET SubscriptionDB=AdventureWorksReplica   
SET Publication=AdvWorksSalesOrdersMerge  
  
--Start the Merge Agent with concurrent upload and download processes.  
-- The following command must be supplied without line breaks.  
"C:\Program Files\Microsoft SQL Server\100\COM\REPLMERG.EXE" -Publication %Publication%    
-Publisher %Publisher%  -Subscriber  %Subscriber%  -Distributor %Publisher%    
-PublisherDB %PublicationDB%  -SubscriberDB %SubscriptionDB% -PublisherSecurityMode 1    
-OutputVerboseLevel 2  -SubscriberSecurityMode 1  -SubscriptionType 1 -DistributorSecurityMode 1    
-Validate 3  -ParallelUploadDownload 1 ;  

使用复制管理对象 (RMO)

可以使用复制管理对象 (RMO) 和托管代码对复制代理功能的访问权限,以编程方式同步请求订阅。 用于同步请求订阅的类取决于订阅所属的发布的类型。

注意

如果您要启动一个自主运行而不影响应用程序的订阅,请异步启动代理。 但是,如果您要监视同步的结果并在同步进程期间从代理处接收回调(例如,要显示进度栏),则应当同步启动代理。 对于 Microsoft SQL Server 2005 Express Edition 订阅者,必须同步启动代理。

将请求订阅与快照或事务发布进行同步

  1. 使用 ServerConnection 类创建与订阅服务器的连接。

  2. 创建 TransPullSubscription 类的实例并设置下列属性:

  3. 调用 LoadProperties 方法以获取其他订阅属性。 如果该方法返回 false,则确保订阅存在。

  4. 使用下列方法之一在订阅服务器中启动分发代理:

  2. 创建 MergePullSubscription 类的实例并设置下列属性:
