Configuring CPU Core Count
Oracle Database Appliance is delivered with all 36 cores on each server enabled. Follow this procedure to reduce the number of cores, if required.
- To reduce the number of cores, run the following command on Node 0 only:Set the cores in multiples of 2, for example, 12:
[root@oak1 opt]# /opt/oracle/dcs/bin/odacli update-cpucore --cores 12
- Check if the job completed successfully:
[root@oak1 opt]# /opt/oracle/dcs/bin/odacli describe-job -i job_ID
- Verify that the core count is updated on both nodes:
[root@oak1 opt]# /opt/oracle/dcs/bin/odacli describe-cpucore
