Please Explain "Max CPU Usage" To Me
896971Feb 26 2013 — edited Feb 27 2013If this is as simple as "RTFM n00b" then please give me the link to the proper documentation page, because after quite a bit of reading, I'm no nearer an answer.
Oracle Cloud Control shows me in the "Top Activity" page that my CPU usage significantly exceeds the "CPU Cores" line (this red line appears to be called "Maximum CPU Line" in other areas?). This CPU Cores line sits at 1.0. The activity monitor shows my CPU usage at the 2.2 mark (obviously exceeding the red line by a significant margin).
However, I go over to the "Hosts" page and look at the "CPU Utilization" graph and it never shows CPU usage above 13%.
The host has 4 virtual CPUs and the database is 11r2.
What is going on here? Again, if this is all discussed in a man file somewhere, please direct me.
Thanks so much!
p.s.---posted this in another Oracle forum, but it looks awfully dead over there!
