Résumé :
Pour optimiser la performance et prévenir les erreurs de liveCache, il est essentiel de configurer correctement les paramètres du système d’exploitation, spécialement après des modifications telles que les changements de DATA_CACHE ou CACHE_SIZE, les mises à jour selon la Note 425051, l’augmentation des données de Devspaces, et les ajustements de MAXUSERTASKS et/ou MAXCPU. Une configuration inadéquate peut empêcher le démarrage de liveCache. Les restrictions du système d’exploitation qui limitent l’allocation de mémoire ou le nombre requis de threads noyau utilisateur contribuent également à ces problèmes. SAP recommande de vérifier les paramètres nécessaires tels que MAXCPU, OMS_HEAP_LIMIT, etc., dans des notes détaillées et de s’assurer que la configuration de liveCache et celle du système d’exploitation sont alignées, avec un espace SWAP suffisant et des niveaux de package pris en charge.
