We have purchased Oracle Database Named User Plus licenses since we know the number of employees who will be using the installed programs on a single or multiple servers. What else should we take into consideration?

Bei der Metrik Named User Plus sind nicht nur die von Ihnen autorisierten namentlich benennbaren natürlichen Personen lizenzrechtlich zu zählen, die installierte Programme auf einem einzelnen oder mehreren Servern nutzen, sondern auch nicht menschlich betriebene Geräte (non human operated Device) wenn diese auf Programme zugreifen können.

When using Named User Plus licenses, you not only have to count the designated individuals that are using the installed programs on a single serve or multiple servers, bus as well the non human operated devices which can access the installed programs. For software licensing, the minimum number of users or the total number of users actually accessing the database is relevant. Whichever of the two is higher is the number that needs to be taken into consideration.
