IBM DB2 manual Processor Value Unit license, Processor Value Units per core

An Authorized User is defined as one and only one individual with a specific identity within or outside your organization. Each Authorized User has a unique specific identity and ID, which cannot be shared or transferred unless there is a change in employment status. An ID can establish one or more connections to the program and count as a single Authorized User. If an Authorized User makes connections to other DB2 data servers, additional licenses should be acquired for those connections using charge metric for those other DB2 data servers.

Processor Value Unit license

This license is based on the processor rating of the server replacing the previous processor based licensing. Introduction of the multi-core processor prompted a change to the licensing of IBM software. The Processor Value Unit (PVU) assigns a specific number of processor value units to each processor core. This type of processor rating allows sub-capacity licensing, which provides flexibility to address changes in processor technology. Figure 1-3outlines current Processor Value Units per core at the time this book was written.
