Oracle VM VirtualBox Enterprise

Named User Plus license:
A named user is a person authorized to use programs installed on one or more servers, regardless of whether it is using the program at a given time or not.
An automatic device (which does not require human participation) with the possibility of access to programs is considered a user (NUP) in addition to all persons authorized to use the programs. When using multiplexing hardware or software (transaction monitor, web server) this number must be defined at the input of the multiplexer. One and the same employee of the enterprise can work with any server in the enterprise on which the Oracle Database is located, i.e. To work with 10 servers you need 1 license.
Processor license:
This type of licensing is applied in the case when it is not possible to accurately determine the number of users or their number is very large. With this scheme, all processors of the system on which programs are installed and / or run are licensed.
Access to programs can be provided to both internal users of the organization and to third parties, which implies an unlimited number of users.
When using multi-core systems (for Standard Edition One and Standard Edition) only the number of processors (sockets) on the server is taken into account, i.e. The number of cores in each processor is not taken into account.
