WARNING: On most platforms, Oracle automatically sets the value of CPU_COUNT to the number of CPUs available to your Oracle instance. Do not change the value of CPU_COUNT. 

CPU_COUNT specifies the number of CPUs available to Oracle. Oracle uses it to set the default value of the LOG_SIMULTANEOUS_COPIES parameter. On single-CPU computers, the value of CPU_COUNT is 1.

If your system experiences heavy contention for latches, change the value of LOG_SIMULTANEOUS_COPIES to twice the number of CPUs you have. Do not change the value of CPU_COUNT.

See Also: Your operating system specific Oracle documentation for more information about this parameter.
