Ejemplo: Evitar la copia de datos en el momento de la publicación

Esta secuencia de comandos impide que se copien los datos al servidor en el momento de la publicación. La opción de bloquear la copia de los datos está disponible a partir ArcGIS 10.1 Service Pack 1.

Al publicar un elemento como un documento de mapa a ArcGIS Server, el servidor comprueba todas las fuentes de datos a las que se hace referencia en el documento para determinar si están registradas en ArcGIS Server. Los datos de las fuentes que no estén registradas se copian en el servidor de forma predeterminada y se colocan en los directorios del servidor. Como administrador del servidor, puede querer bloquear la copia de los datos para forzar el registro de datos y evitar que se acumulen datasets en el servidor.

Basta con ejecutar esta secuencia de comandos una sola vez para bloquear todas las copias de datos.
