Why I did not have any answers to this question? Why I cannot find it any more in the discussion list?
Sorry for the delay.
2. Oracle Licensing in VMware Environments
Many Oracle products, including the database, are licensed by physical processor. This licensing model works well
in a physical world, in which customers typically run one application per host and physical processors are easy to
track. But this model is not well-adapted to a virtual world. VMware vSphere enables you to consolidate multiple
workloads in the form of virtual machines on a single host. Additionally, VMware enables you to move these virtual
machines across hosts with VMware vMotion®, VMware Distributed Resource Scheduler (DRS) and High
Availability (HA). When running products that are licensed by physical processor on vSphere, customers should
ensure the following:
• Virtual machines are running on hosts fully licensed for Oracle.
• Virtual machine movement within a cluster is restricted to hosts that are fully licensed for Oracle. (You can do this using DRS VM-host must rule )
• Virtual machine movements are tracked so that customers are able to demonstrate compliance with Oracle
I suggest you to read entire white paper.
