Khairul_1 — Mon, 16 Jun 2008 12:24:14 GMT

Hi,

We have rx5670 HP-UX 11i v2 11.23 trusted cluster running system from last 4 years.

Could any one help us to wright a script for collect maximum process running in the system with threshhold. like ps -ef | grep oracle | wc -l >> /tmp/oracleprocess/process.txt

What are you trying to measure? The number of oracle processes? Do you only want to log it if more than your threshhold number?

(I've ask this be moved to HP-UX > languages & scripting.)

if you re interested in the number of processes whatever they re coming from you may use kcusage and look the nproc value
for a hourly summary
kcusage -h nproc

What do you mean by 'threshold'? System limit (tuning)?

Can you explain the problem in detail?

Hi,

for the process with the highest amount of cpu time you can use
ps -ef|grep -v " [0-9]:"|sort -rn +7 -8

or just use "top" (/usr/bin/top)

Regards,

Franky
