La formation Red Hat® Enterprise Performance Tuning (Optimisation des performances de Red Hat Enterprise) a pour but d'enseigner aux administrateurs de systèmes Linux® confirmés la méthodologie à appliquer pour optimiser les performances pour Red Hat Enterprise Linux. Ce cours aborde le concept d'architecture système en mettant l'accent sur la compréhension de ses implications sur les performances du système, des méthodes pour tester les effets de l'affinage des performances, des utilitaires de référence Open Source, des méthodes d'analyse des performances du système et de la mise en réseau, et l'optimisation des configurations pour des charges d'applications spécifiques.\nUn ingénieur certifié Red Hat (RHCE®) ayant suivi l'intégralité de ce cours est en mesure de passer l'examen d'expertise Red Hat Enterprise Performance Tuning (Optimisation des performances de Red Hat Enterprise) (EX442).<\/p>","essentials":"
