同步推送订阅

适用于: SQL Server Azure SQL 数据库

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 中同步推送订阅。

注意

对于快照复制和事务复制,Azure SQL 托管实例可以是发布服务器、分发服务器和订阅服务器。 对于快照复制和事务复制,Azure SQL 数据库中的数据库只能是推送订阅服务器。 有关详细信息,请参阅使用 Azure SQL 数据库Azure SQL 托管实例进行事务复制。

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

从 Microsoft SQL Server Management Studio 的“本地发布”和“本地订阅”文件夹及复制监视器的“所有订阅”选项卡中,按需同步订阅。 不能从订阅服务器按需同步对 Oracle 发布的订阅。 有关启动复制监视器的信息,请参阅启动复制监视器

在 Management Studio 中按需同步推送订阅(在发布服务器中)

  1. 在 Management Studio 中连接到发布服务器,然后展开服务器节点。

  2. 展开 “复制” 文件夹,再展开 “本地发布” 文件夹。

  3. 展开要同步其订阅的发布。

  4. 右键单击要同步的订阅,然后单击 “查看同步状态”

  5. 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”

  6. 单击“关闭” 。

在 Management Studio 中按需同步推送订阅(在订阅服务器中)

  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. 将显示一条消息,指示建立与分发服务器的连接。 单击“确定”。

  5. 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”

  6. 单击“关闭” 。

在复制监视器中按需同步推送订阅

  1. 在复制监视器的左窗格中依次展开发布服务器组、发布服务器,再单击一个发布。

  2. 单击 “所有订阅” 选项卡。

  3. 右键单击要同步的订阅,然后单击 “开始同步”

  4. 若要查看同步进度,请右键单击该订阅,然后单击 “查看详细信息”

使用复制代理

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推送订阅。 被调用的复制代理可执行文件将取决于推送订阅所属的发布的类型。

启动分发代理以将推送订阅与事务发布进行同步

  1. 通过命令提示符或分发服务器中的批处理文件,执行 distrib.exe。 指定下列命令行参数:

    • -Publisher

    • -PublisherDB

    • -Distributor

    • -Subscriber

    • -SubscriberDB

    • -SubscriptionType = 0

    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 = 0

    • -PublisherLogin

    • -PublisherPassword

    • -PublisherSecurityMode = 0

    • -SubscriberLogin

    • -SubscriberPassword

    • -SubscriberSecurityMode = 0

      重要

      请尽可能使用 Windows 身份验证。

启动合并代理以将推送订阅与合并发布进行同步

  1. 通过命令提示符或分发服务器中的批处理文件,执行 replmerg.exe。 指定下列命令行参数:

    • -Publisher

    • -PublisherDB

    • -Publication

    • -Distributor

    • -Subscriber

    • -SubscriberDB

    • -SubscriptionType = 0

    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 = 0

    • -PublisherLogin

    • -PublisherPassword

    • -PublisherSecurityMode = 0

    • -SubscriberLogin

    • -SubscriberPassword

    • -SubscriberSecurityMode = 0

      重要

      请尽可能使用 Windows 身份验证。

示例(复制代理)

以下示例启动分发代理以同步推送订阅。

  
REM -- Declare the variables.  
SET Publisher=%instancename%  
SET Subscriber=%instancename%  
SET PublicationDB=AdventureWorks2022  
SET SubscriptionDB=AdventureWorks2022Replica   
SET Publication=AdvWorksProductsTran  
  
REM -- Start the Distribution Agent with four subscription streams.  
REM -- The following command must be supplied without line breaks.  
"C:\Program Files\Microsoft SQL Server\120\COM\DISTRIB.EXE" -Subscriber %Subscriber%   
-SubscriberDB %SubscriptionDB% -SubscriberSecurityMode 1 -Publication %Publication%   
-Publisher %Publisher% -PublisherDB %PublicationDB% -Distributor %Publisher%   
-DistributorSecurityMode 1 -Continuous -SubscriptionType 0 -SubscriptionStreams 4  
  

以下示例启动合并代理以同步推送订阅。

  
REM -- Declare the variables.  
SET Publisher=%instancename%  
SET Subscriber=%instancename%  
SET PublicationDB=AdventureWorks2022  
SET SubscriptionDB=AdventureWorks2022Replica   
SET Publication=AdvWorksSalesOrdersMerge  
  
REM -- Start the Merge Agent.  
REM -- The following command must be supplied without line breaks.  
"C:\Program Files\Microsoft SQL Server\120\COM\REPLMERG.EXE"  -Publisher %Publisher%   
-Subscriber  %Subscriber%  -Distributor %Publisher% -PublisherDB  %PublicationDB%   
-SubscriberDB %SubscriptionDB% -Publication %Publication% -PublisherSecurityMode 1   
-OutputVerboseLevel 3  -Output -SubscriberSecurityMode 1  -SubscriptionType 0   
-DistributorSecurityMode 1  
  

使用复制管理对象 (RMO)

可以使用复制管理对象 (RMO) 和托管代码的复制代理功能访问权限以编程方式同步推送订阅。 用于同步推送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,您要显示进度栏),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。

将推送订阅与快照发布或事务发布进行同步

  1. 使用 ServerConnection 类创建与分发服务器的连接。

  2. 创建 TransSubscription 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分发服务器中启动分发代理:

将推送订阅与合并发布进行同步

  1. 使用 ServerConnection 类创建与分发服务器的连接。

  2. 创建 MergeSubscription 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分发服务器中启动合并代理:
