Cómo configurar una suscripción para usar la sincronización web (programación con RMO)

El procedimiento descrito en este tema es el tercer paso para configurar la sincronización web para la replicación de mezcla. Lleve a cabo este paso después de habilitar la publicación y configurar el equipo que ejecuta Microsoft Internet Information Services (IIS). Para obtener información general acerca del proceso de configuración, vea Cómo configurar la sincronización web para la replicación de mezcla (programación con RMO). Al configurar una suscripción para utilizar la sincronización web para suscriptores que sólo puedan conectarse al publicador a través de HTTP, debe configurar correctamente la publicación. Para obtener más información, vea Cómo configurar una publicación para que permita la sincronización web (programación con RMO). Después de realizar los procedimientos de este tema, sincronice la suscripción que ha creado. Para obtener más información, vea Cómo sincronizar una suscripción de extracción (programación con RMO).

En este tema se describen los parámetros que requiere la sincronización web. Para obtener más información acerca de cómo crear una suscripción de extracción, vea Cómo crear una suscripción de extracción (programación con RMO).

Nota importanteImportante

La dirección URL del servidor web que se usa para la sincronización web (como https://servidor.dominio.com/ directorio replisapi.dll) especifica la ubicación de replisapi.dll. Si el servidor está configurado para usar un puerto diferente del puerto predeterminado 443 para la Capa de sockets seguros (SSL), también debe proporcionar el puerto: https://servidor.dominio.com:númeroDePuerto/directorio/replisapi.dll. El nombre del servidor en la dirección URL debe ser idéntico al que usó al crear el certificado SSL (Capa de sockets seguros) para IIS. Por ejemplo, en una intranet, es posible que pueda obtener acceso a un servidor web a través de https://servidor/. Sin embargo, si se usó el nombre completo (por ejemplo, https://servidor.dominio.com/) al crear el certificado, debe usarlo también en la dirección URL (https://servidor.dominio.com/directorio/replisapi.dll).

Para configurar una suscripción para que use la sincronización web

  1. Cree conexiones al suscriptor y al publicador con la clase ServerConnection.

  2. Cree una instancia de la clase MergePublication con la conexión de publicador del paso 1.

  3. (Opcional) Si la base de datos de suscripciones no existe, cree la base de datos con los objetos de administración de SQL Server (SMO) Database. Para obtener más información, vea Crear, modificar y eliminar bases de datos.

  4. Cree una instancia de la clase MergePullSubscription.

  5. Establezca las siguientes propiedades de la suscripción:

  6. Llame al método Create.

  7. Mediante la instancia de MergePublication del paso 2, llame al método MakePullSubscriptionWellKnown para registrar la suscripción de extracción con el publicador.

Para configurar una suscripción que use la sincronización web para suscriptores que sólo puedan conectarse al publicador a través de un servidor web con HTTP

  1. Cree una conexión al suscriptor mediante la clase ServerConnection.

  2. (Opcional) Si la base de datos de suscripciones no existe, cree la base de datos con la clase SMO Database. Para obtener más información, vea Crear, modificar y eliminar bases de datos.

  3. Cree una instancia de la clase MergePullSubscription.

  4. Establezca las siguientes propiedades de la suscripción:

  5. Llame al método Create.
