CPU% is over 100% (command extract HP UX)

[tran cam ngan]

Hi,

I used the command extract -xp -p -r -f (HP-UX 11vi) to obtain the consumption of CPU by process. I obtained the following results for the process java. The curious thing that the total CPU% is over than 100%. I get 1978.24% / 8 CPUs -> 1CPU = 247;28%. How can I explain it? A bug of extract command?

Nbre CPU: 8 30-mars

What version of java are you running ?

What patches do you currently have installed related to java ?

I runned find / -name java*.* and found opt/java1.2, opt/java1.3. It wasn't me who did execute this process (it was our client). I observed & analysed the system performance, maybe java 1.3.1. Is it normal to have %CPU 247% by CPU?

I am not familiar with "extract" which is why I didn't comment on that particular part of your question.

CPU % shouldn't be higher than 100% (for obvious reasons).
