同步请求订阅
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
在 Management Studio 中连接到订阅服务器，然后展开服务器节点。
展开 “复制” 文件夹，再展开 “本地订阅” 文件夹。
右键单击要同步的订阅，然后单击 “查看同步状态”。
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” 。
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
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
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
使用 ServerConnection 类创建与订阅服务器的连接。
创建 TransPullSubscription 类的实例并设置下列属性：
用于 DatabaseName的订阅数据库的名称。
用于 PublicationName的订阅所属的发布的名称。
为 PublicationDBName设置发布数据库的名称。
用于 PublisherName的发布服务器的名称。
在步骤 1 中为 ConnectionContext创建的连接。
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。
使用下列方法之一在订阅服务器中启动分发代理：
在步骤 2 中的 SynchronizeWithJob 实例上调用 TransPullSubscription 方法。 该方法异步启动分发代理，并在代理作业运行时立即将控制权返回给您的应用程序。 你不能为 SQL Server 2005 Express Edition 订阅服务器调用该方法，如果创建的订阅的 CreateSyncAgentByDefault 为 false（默认值），则也不能调用该方法。
获取 TransSynchronizationAgent 属性中 SynchronizationAgent 类的实例，然后调用 Synchronize 方法。 该方法可以同步启动代理，并且控制权仍属于运行代理作业。 在执行同步期间，您可以在代理仍旧运行的情况下处理 Status 事件。
注意
如果您在创建请求订阅时将 false for CreateSyncAgentByDefault （默认值），则还需要指定 Distributor复制代理 DistributorSecurityMode，并选择性地指定 DistributorLogin 和 DistributorPassword ，因为 MSsubscription_properties。
将请求订阅与合并发布进行同步
使用 ServerConnection 类创建与订阅服务器的连接。
创建 MergePullSubscription 类的实例并设置下列属性：
用于 DatabaseName的订阅数据库的名称。
用于 PublicationName的订阅所属的发布的名称。
将 PublicationDBName设置为已发布的数据库的名称。
用于 PublisherName的发布服务器的名称。
在步骤 1 中为 ConnectionContext创建的连接。
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。
使用下列方法之一在订阅服务器中启动合并代理：
在步骤 2 中的 SynchronizeWithJob 实例上调用 MergePullSubscription 方法。 该方法异步启动合并代理，并在代理作业运行时立即将控制权返回给您的应用程序。 你不能为 SQL Server 2005 Express Edition 订阅服务器调用该方法，如果创建的订阅的 CreateSyncAgentByDefault 为 false（默认值），则也不能调用该方法。
获取 MergeSynchronizationAgent 属性中 SynchronizationAgent 类的实例，然后调用 Synchronize 方法。 该方法可以同步启动合并代理，并且控件仍属于运行代理作业。 在执行同步期间，您可以在代理仍旧运行的情况下处理 Status 事件。
注意
如果您在创建请求订阅时将 false for CreateSyncAgentByDefault （默认值），则还需要指定 Distributor复制代理 DistributorSecurityMode复制代理 PublisherSecurityMode复制代理 HostName复制代理 SubscriptionType复制代理 ExchangeType，并选择性地指定 DistributorLogin复制代理 DistributorPassword复制代理 PublisherLogin和 PublisherPassword ，因为 MSsubscription_properties。
