If you look at 11g, it actually has some logic that can distinguish between sockets and cores- Not sure where I saw it but I clearly remember it. Perhaps it was Cluster Verification Utility, in which case the installer is also aware of it. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of D'Hooge Freek Sent: Saturday, April 17, 2010 10:36 AM To: RStorey@xxxxxxxxxxxxxxxxxx; oracle-l@xxxxxxxxxxxxx Subject: RE: RE: Licencing Also remember that Oracle works only with cpu cores when dealing with enterprise edition. With standard edition you need to look at the socket (or chip to be exact, although I have never known Oracle to really look at the number of chips). So a server with a quad core cpu only needs 1 standard edition cpu license. regards, Freek D'Hooge Uptime Oracle Database Administrator email: freek.dhooge@xxxxxxxxx tel +32(0)3 451 23 82 http://www.uptime.be disclaimer: www.uptime.be/disclaimer ________________________________________ From: oracle-l-bounce@xxxxxxxxxxxxx [oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Storey, Robert (DCSO) [RStorey@xxxxxxxxxxxxxxxxxx] Sent: 16 April 2010 16:01 To: oracle-l@xxxxxxxxxxxxx Subject: RE: RE: Licencing Good catch.
