Den nøjagtige genfordeling vil udføre genfordeling af ekstra hukommelse kun op til den øverste grænse, der er angivet.Når du passerer den øverste grænse for in-memory under genfordeling, vil de cachede data kopieres til disken, hvis det er muligt.Når du passerer den øverste grænse for diskminne under genfordeling, kastes den relevante undtagelse.Udførelsen skal være højere, hvis denne mulighed er slået af, da der ikke udføres yderligere kopiering, hvis det er muligt,Dette kan dog også føre til at overskride de øvre grænser, der er angivet for hukommelse eller disk.
