In my rx3600 server the cpu utilisation always showing more than 100%.
The main process which is consuming more CPU is "JAVA".Please find the attachment.
Server Configuration:
rx3600
CPU info: Number of CPUs = 4
Clock speed = 1595 MHz
Memory = 12257 MB (11.969727 GB)

You might try asking in an HP-UX forum,
instead of in this Tru64 forum.
> Please find the attachment.
This might be easier if you attached one.

Re: Java consuming too much CPU resources
Have you tried glance or HPjmeter to check your performance?

Re: Java consuming too much CPU resources
This is either Java or the app.
Or both.
Find the leak, then act:

Re: Java consuming too much CPU resources
I have used hpjmeter for monitoring java, The cpu usage and Java Method hotspot output is there in the attached file (1)
Hi Michael,
System is not accepting sopme options from the given command eg:- rss & a (sort -rna)
So i have run the commands as follows and the output is there in the attached file.
UNIX95=1 ps -e -o vsz,sz,pid,ppid,comm | sort -rn | head
UNIX95=1 ps -e -o cpu,pcpu,state,pid,ppid,comm | sort -rn | head
Hi Steven,
This is an application called TCServer (Temenos core banking service) which is using java.
I am not having any problem with memory, but the bottleneck is there with cpu.
Thanks & waiting for the reply,
Manoj K

Re: Java consuming too much CPU resources
Basically top has:
119.35% in java and steady, using 840 Mb. jpqn is also using a lot.
HPjmeter says you are spending 89% of your time in Util.splitV.
So you need to talk to the developers.

Re: Java consuming too much CPU resources
Have you considered analyzing what the *application* code is doing?
