I recently had to cap the number of active CPUs on a bare metal ODA X5-2, and I noticed that the procedure is slightly different from what I used in the past (link to initial post).
Perform the following steps to generate the Core Key:
- Login to My Oracle Support (MOS) and click the submenu Systems.
- Select the serial number of the appliance and click on “Core Configuration”in the Asset Details Screen
- Select Manage Key
- From the Combo list select the number of cores to activate and click Generate Key to generate the key.
- Click Copy Key to Clipboard to copy the key to the clipboard.
- Paste the key into an empty text file and save the file to a location on the Oracle Database Appliance.
ODA X5-2 initial number of CPU Cores
[root@odax5-2n0 ~]# cat /proc/cpuinfo | grep -i processor processor : 0 processor : 1 processor : 2 processor : 3 ... ... .. . processor : 70 processor : 71 [root@odax5-2n0 ~]# cat /proc/cpuinfo | grep -i processor |wc -l 72 [root@odax5-2n0 ~]#
Checks before enforcing the CPU restriction:
