I have a process in my TOP output that is consistantly at 97% usage. I have 16 CPUs on my box. So is the 97% the cumalative usage of all the CPUs or just one?
Here's the output:
load averages: 9.57, 9.49, 9.99; up 32+23:28:00 20:10:29
1102 processes: 1088 sleeping, 5 zombie, 9 on cpu

19647 orahfprd 1 59 0 9089M 9069M sleep 14:53 21.88% oracle
That process is using 94.56% of a single cpu.
Phew! Thanks
