_cpu_count
As per metalink, meant for those exceptional Operating Systems, where OS does not
support a system call so that Oracle can get the number itself.
So normally this value is not required to be set by DBAs. You have to set this when
cpu_count is not showing the actual number of CPUs.
Title: RE: _cpu_count vs cpu_count
Tanel,
33 cpu_count initial number of cpu's for this instance system modifiable
34 _cpu_count current number of cpu's for this instance non-modifiable
For most of hidden parameters x$ksppsv.ksppstvl set to 0 by default.
