Oracle has been very clear about not respecting VMWare’s ability to limit applications to a subset of cpu’s on a single server. I believe they have been less than clear about failover in a virtual environment when failover is to a completely separate piece of hardware.

The last time I talked with Oracle on this question, the response was that you have to license oracle based on the physical hardware of the box.

Good question and I don’t know the answer for sure. I’ve never seen the answer for that specific scenario in any Oracle documentation. My guess is that it would fall under what they consider to be “Failover” as defined on page 20 of the Software Investment Guide (http://www.oracle.com/corporate/pricing/sig.pdf), which means the other hosts don’t have to be licensed unless we run Oracle on them for more than 10 days in a year. Currently we are licensed only for the physical hardware on the hosts where the databases run and we recently passed an Oracle Licensing audit so I guess we’re okay. From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Stephens, Chris I’m curious how licensing works with VMotion. Do you have to license oracle for the all hosts in the environment, including the host(s) that aren’t being used until failover? ________________________________ Privileged/Confidential Information may be contained in this message or attachments hereto.
