How do I limit the number of CPUs activated in Red Hat Enterprise Linux ?

Solution Verified - Updated -

Issue

  • Limit number of CPUs available in a RHEL system
  • We would like to limit the number of CPU a system can get access to because of ISVs core-licensing. According to the information cpu-hotplug from kernel documentation (http://www.kernel.org/doc/Documentation/cpu-hotplug.txt) seems that it is harmless. Can you please confirm this mechanism can be used on RHEL systems without problems?

Environment

  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 6
