如何验证订阅服务器上的数据（RMO 编程）

通过复制，您可以使用复制管理对象 (RMO) 以编程方式验证订阅服务器上的数据是否与发布服务器上的数据匹配。使用的对象取决于复制拓扑的类型。事务复制要求验证发布的所有订阅。

验证事务发布中所有项目的数据

使用 ServerConnection 类创建与发布服务器的连接。
创建 TransPublication 类的实例。设置发布的 Name 和 DatabaseName 属性。将 ConnectionContext 属性设置为步骤 1 中创建的连接。
调用 LoadProperties 方法获取该对象的其余属性。如果此方法返回 false，则说明步骤 2 中的发布属性定义不正确，或者此发布不存在。
调用 ValidatePublication 方法。传递以下参数：
- ValidationOption
- ValidationMethod
- 一个布尔值，指示是否在验证完成后停止分发代理。
这将把项目标记为等待验证。
如果尚未运行，则启动分发代理以同步每个订阅。有关详细信息，请参阅如何同步推送订阅（RMO 编程）或如何同步请求订阅（RMO 编程）。验证操作的结果将写入代理历史记录。有关详细信息，请参阅如何以编程方式监视复制（RMO 编程）。

验证合并发布的所有订阅中的数据

使用 ServerConnection 类创建与发布服务器的连接。
创建 MergePublication 类的实例。设置发布的 Name 和 DatabaseName 属性。将 ConnectionContext 属性设置为步骤 1 中创建的连接。
调用 LoadProperties 方法获取该对象的其余属性。如果此方法返回 false，则说明步骤 2 中的发布属性定义不正确，或者此发布不存在。
调用 ValidatePublication 方法。传递所需的 ValidationOption。
对每个订阅运行合并代理以开始验证，或者等待下一个计划的代理运行。有关详细信息，请参阅如何同步请求订阅（RMO 编程）和如何同步推送订阅（RMO 编程）。验证操作的结果将写入代理的历史记录，您可以使用复制监视器查看。有关详细信息，请参阅如何以编程方式监视复制（RMO 编程）。

验证合并发布的单个订阅中的数据

使用 ServerConnection 类创建与发布服务器的连接。
创建 MergePublication 类的实例。设置发布的 Name 和 DatabaseName 属性。将 ConnectionContext 属性设置为步骤 1 中创建的连接。
调用 LoadProperties 方法获取该对象的其余属性。如果此方法返回 false，则说明步骤 2 中的发布属性定义不正确，或者此发布不存在。
调用 ValidateSubscription 方法。传递要验证的订阅服务器和订阅数据库的名称以及所需的 ValidationOption。
对订阅运行合并代理以开始验证，或者等待下一个计划的代理运行。有关详细信息，请参阅如何同步请求订阅（RMO 编程）和如何同步推送订阅（RMO 编程）。验证操作的结果将写入代理的历史记录，您可以使用复制监视器查看。有关详细信息，请参阅如何以编程方式监视复制（RMO 编程）。
