Re: One simple question

Thanks Robert:

15:45:13 SQL> l
 1  select kviival Num_CPU, kviidsc DESCRIPTION
 2  from sys.x$kvii
 3* where kviitag= 'ksbcpu'
15:45:16 SQL> /
more..

  NUM_CPU DESCRIPTION
---------- ----------------------------------------------------------------
        4 number of CPUs in the system

CPU_COUNT seems to show a wrong number. hmm...
I do not know about dual core processor. Will the SAs be able to answer that
question?

The following query will tell you how many CPU's Oracle thinks is on your system:

select kviival Num_CPU, kviidsc DESCRIPTION
from sys.x$kvii
where kviitag='ksbcpu_static';

Oracle has been known in the past to set CPU_COUNT to
something other than the # of CPU's.
