Virtual processor core
The pricing of the Db2® Direct editions is based on the number of virtual processor cores your server uses.
A Virtual Processor Core (VPC) is a processor core in a non-partitioned physical server, or a virtual core assigned to a virtual server. VPCs are used as the unit of measurement by which you must license your program. You must license each VPC made available to the program. A minimum of two VPCs is needed per deployment (one VPC is used for idle or warm standby).
