Cómo eliminar una publicación (programación con RMO)
Puede eliminar publicación mediante programación con Objetos de administración de replicación (RMO). Las clases RMO que utiliza para quitar una publicación dependen del tipo de publicación que quita.
Para quitar una publicación transaccional o de instantáneas
Cree una conexión al publicador mediante la clase ServerConnection.
Cree una instancia de la clase TransPublication.
Establezca las propiedades Name y DatabaseName para la publicación y establezca la propiedad ConnectionContext en la conexión creada en el paso 1.
Compruebe la propiedad IsExistingObject para asegurarse de que la publicación existe. Si el valor de esta propiedad es false, significa que las propiedades de la publicación del paso 3 se definieron incorrectamente, o bien que la publicación no existe.
Llame al método Remove.
(Opcional) Si no existe ninguna otra publicación transaccional para esta base de datos, ésta se puede deshabilitar para la publicación transaccional del siguiente modo:
Cree una instancia de la clase ReplicationDatabase. Establezca la propiedad ConnectionContext en la instancia de ServerConnection del paso 1.
Llame al método LoadProperties. Si este método devuelve false, confirme que la base de datos existe.
Establezca la propiedad EnabledTransPublishing en false.
Llame al método CommitPropertyChanges.
Cierre las conexiones.
Para quitar una publicación de mezcla
Cree una conexión al publicador mediante la clase ServerConnection.
Cree una instancia de la clase MergePublication.
Establezca las propiedades Name y DatabaseName para la publicación y establezca la propiedad ConnectionContext en la conexión creada en el paso 1.
Compruebe la propiedad IsExistingObject para asegurarse de que la publicación existe. Si el valor de esta propiedad es false, significa que las propiedades de la publicación del paso 3 se definieron incorrectamente, o bien que la publicación no existe.
Llame al método Remove.
(Opcional) Si no existe ninguna otra publicación de mezcla para esta base de datos, ésta se puede deshabilitar para la publicación de mezcla del siguiente modo:
Cree una instancia de la clase ReplicationDatabase. Establezca la propiedad ConnectionContext en la instancia de ServerConnection del paso 1.
Llame al método LoadProperties. Si este método devuelve false, compruebe que la base de datos existe.
Establezca la propiedad EnabledMergePublishing en false.
Llame al método CommitPropertyChanges.
Cierre las conexiones.
