Comentarios

Debe especificar la información de la cuenta de Windows mediante la IProcessSecurityContext interfaz devuelta por la SynchronizationAgentProcessSecurity propiedad . Esto no es necesario si un miembro del sysadmin rol fijo de servidor crea la suscripción en el suscriptor.

El Agente de sincronización de una suscripción de extracción siempre se conecta localmente al suscriptor mediante las credenciales de autenticación de Windows proporcionadas mediante la SynchronizationAgentProcessSecurity propiedad . Para obtener información sobre las conexiones que realizan los agentes y los permisos necesarios para esas conexiones, consulte Modelo de seguridad del agente de replicación.

La SynchronizationAgentProcessSecurity propiedad solo se puede recuperar por miembros del sysadmin rol fijo de servidor en el suscriptor o por miembros del db_owner rol fijo de base de datos en la base de datos de suscripciones.

La SynchronizationAgentProcessSecurity propiedad solo se puede establecer por miembros del sysadmin rol fijo de servidor en el suscriptor o por miembros del db_owner rol fijo de base de datos en la base de datos de suscripciones.

Recuperar la SynchronizationAgentProcessSecurity propiedad equivale a ejecutar sp_helppullsubscription (Transact-SQL) o sp_helpmergepullsubscription (Transact-SQL).

Establecer la SynchronizationAgentProcessSecurity propiedad equivale a ejecutar sp_addpullsubscription_agent (Transact-SQL),sp_addmergepullsubscription_agent (Transact-SQL),sp_change_subscription_properties (Transact-SQL) o sp_changemergepullsubscription (Transact-SQL).
