I would recommend talking to an Oracle representative directly about this because there tends to float a whole lot of information around (sometimes even by techs) that may or may not be entirely accurate. Best bet is to go to the source. Kris On Tue, Aug 11, 2009 at 04:16:42PM -0500, Jam

A z10 processor has 4 cores, but each IFL/ZIIP/ZAAP/GP is really only one of those cores. So licensing for an IFL should count as one Oracle license (1 core). One other thing you'll find is that they have a multiplier depending on the core type/speed. I think the multiplier for z hardware is 100

Question regarding Oracle Licensing

2009-08-11 Thread James Peddycord
I was on a conference call with a couple of Oracle techs who said that Oracle is licensed on a "per core" basis, so that each IFL on a z/10 would count as 4 full price Oracle licenses. Has anyone else had experience with this? Is this correct? Thanks, Jim P. --

Yes - doing this either in the PROFILE EXEC or the directory would eliminate the issue... we were trying to get it working dynamically before we 'hardcoded it' ;-) So this is just a gotcha for dynamic define/coupling... Thanks for your post! Scott On Tue, Aug 11, 2009 at 2:18 PM, Steffen M

I got this working.. and the secret was eliminating the time between the 'define nic' and the 'couple'.. When I did the define nic - I saw messages on the console that it recognized 900 as a QDIO, etc -- but failed to register the IP address and some other messages. So - I tried logging into t
