Standard Processor-Based LicensingQ. License Definitions and RulesProcessor: shall be defined as all processors where the Oracle programs areinstalled and/or running. Programs licensed on a processor basis may beaccessed by your internal users (including agents and contractors) and by your thirdparty users. The number of required licenses shall be determined by multiplying thetotal number of cores of the processor by a core processor licensing factor specifiedon the Oracle Processor Core Factor Table which can be accessed athttp://oracle.com/contracts.CONFIDENTIAL AND PROPRIETARY 2021
