As many of you may know, Oracle technology can be licensed on a processor basis.
But what is a processor? As a technologist, speaking to other technologists there is generally a tacit understanding of what this is. However recent changes in technology have led to Oracle creating examples and illustrating licensing rules.
This is not just an Oracle problem. There is an interesting article here: http://sageza.com/available/Snapshot/StratSN%205-16-06%20Processors.pdf which illustrates the wider problem in the community. I would be interested to hear any views on this subject and whether perhaps a standard definition needs to be agreed between vendors.
Of course, as shown in the licensing rules above there is always the alternative of using Named User Plus as the metric.
