Comentarios

La recolección de elementos no utilizados distribuidos es responsable de controlar las duraciones de las aplicaciones de servidor y de eliminarlas cuando hayan expirado sus duraciones. Tradicionalmente, la recolección de elementos no utilizados distribuido usa recuentos de referencias y ping para el control. Esto funciona bien cuando hay algunos clientes por objeto, pero no funciona bien cuando hay miles de clientes por cada objeto. El servicio de duración puede asumir la función de un recolector de elementos no utilizados distribuido tradicional y se escala bien cuando aumenta el número de clientes.

El servicio de duración asocia una concesión a cada objeto activado de forma remota. Cuando expira la concesión, se quita el objeto .
