Comentarios

La MaxDistributionRetention propiedad especifica el periodo máximo de retención antes de que se eliminen las transacciones. Las suscripciones que aún no han recibido comandos replicados y que sean anteriores al periodo máximo de retención de la distribución se marcan como inactivas.

La MaxDistributionRetention propiedad solo puede ser recuperada por miembros del db_owner rol de base de datos fijo replmonitor en la base de datos de distribución, por usuarios en la lista de acceso a publicaciones (PAL) de una publicación que utilicen la base de datos de distribución, o por usuarios con permiso SELECT en la tabla del sistema MSdistributiondbs en la base de datos de distribución.

La MaxDistributionRetention propiedad solo puede ser configurada por miembros del sysadmin rol fijo del servidor en el Distribuidor.

Recuperar la MaxDistributionRetention propiedad equivale a ejecutar sp_helpdistributiondb.

Establecer la MaxDistributionRetention propiedad equivale a ejecutar sp_adddistributiondb o sp_changedistributiondb.
