Hi Thomas,

only note - on bare-metal servers output form “cat /proc/cpuinfo|grep processor|wc –l” usually show the number of threads (if multithreading is on) then number of cores is half of it. Try command "lscpu". Number of cores you can also see in oracle alert.log during instance startup (since, e.g.

Initial number of CPU is 16
Number of processor cores in the system is 8 Number of processor sockets in the system is 2

Subject:        Another licensing Q
Sent by:

Question related to Oracle CPU licensing on Cisco UCS. My current blade has 32 cores (the result of “cat /proc/cpuinfo|grep processor|wc –l”). The sysadmin disabled all but four cores on each socket via the UCS BIOS and got the output of 8 when I ran the same command the second time. The OS only sees 8. The question is does Oracle allow me to license only 8 visible cores, or do I have to still license all 32 present on the blade?

I believe such licensing is possible on ODA (Oracle Database Appliance). With bare-metal, you disable cores that will not be used by the Oracle Database by adding your hardware Support Identifier (SI) for Oracle Database Appliance to your My Oracle Support account and creating a key.

Thanks much!
