Named User Plus: is defined as an individual authorized by you to use the programs which are installed on a single server or multiple servers, regardless of whether the individual is actively using the programs at any given time. A non human operated device will be counted as a named user plus in addition to all individuals authorized to use the programs, if such devices can access the programs. If multiplexing hardware or software (e.g., a TP monitor or a web server product) is used, this number must be measured at the multiplexing front end. Automated batching of data from computer to computer is permitted. You are responsible for ensuring that the named user plus per processor minimums are maintained for the programs contained in the user minimum table in the licensing rules section; the minimums table provides for the minimum number of named users plus required and all actual users must be licensed.
Processor: shall be defined as all processors where the Oracle programs are installed and/or running. Programs licensed on a Processor basis may beaccessed by your internal users (including agents and contractors) and by your third party users.
Processor Calculations
The total number of processors (see above for definition of a processor) needed is calculated by adding the number of processors in each computer where the programs are installed and/or running.
