Abstract

L'invention concerne un appareil d'interface de gestion de notifications ascendantes et un procédé pour sa gestion, visant à améliorer la stabilité d'un système. Le procédé comporte les étapes consistant à enregistrer des informations modifiées de notification par abonnement dans un fichier d'informations de notification lorsqu'un message de notification, auquel est abonnée une gestion de réseau de niveau supérieur, est modifié ; vérifier si un premier serveur de notification, en tant que serveur actuel de notification fonctionne anormalement ; lorsque la vérification indique que le premier serveur de notification fonctionne anormalement, lire les informations de notification par abonnement enregistrées dans le fichier d'informations de notification et les charger dans un deuxième serveur de notification ; basculer vers le deuxième serveur de notification en tant que serveur actuel de notification. L'appareil comprend un module d'accès à l'interface de gestion de notifications ascendantes, un module de surveillance de liaisons, un module de chargement en ligne de fichiers et un module de permutation à chaud. Le procédé de sauvegarde à chaud utilisant des serveurs de notification dédoublés selon la présente invention permet à une notification de continuer à être signalée lorsqu'un serveur-maître de notification est défaillant, d'où un fonctionnement stable du système et une amélioration de la tolérance aux pannes du système.
