Abstract

L'invention concerne un procédé, un appareil et un dispositif de gestion de ressources. Le procédé selon l'invention consiste : à configurer une première ressource utilisée pour lire un fichier associé d'une première application (1041) ; à obtenir une première ressource de cache occupée lorsque le fichier associé de la première application est lu (1042) ; et si la taille de la première ressource de cache dépasse la taille de la première ressource, à déterminer une deuxième ressource et à effacer la deuxième ressource de la première ressource de cache, de sorte que les ressources restantes après que la deuxième ressource a été effacée continuent à lire le fichier associé de la première application (1043). Selon le procédé, une valeur seuil, à savoir la taille de la première ressource, est réglée pour réguler la taille de la première ressource de cache occupée par la lecture du fichier associé de la première application pour qu'elle ne dépasse pas la valeur seuil, de sorte à éviter une situation dans laquelle le fonctionnement et l'utilisation d'autres applications sont affectées en raison d'une occupation illimitée de ressources de cache par la première application, et à augmenter le taux d'utilisation de ressources de cache de fichier.
