I wanna down tht particular CPU only with out interrupting the other 15
CPU's. how can i do this. is there any command for this ?? (5 Replies)
hi,
i want to know cpu utilizatiion per process per cpu..for single processor also if multicore in linux ..to use these values in shell script to kill processes exceeding cpu utilization.ps (pcpu) command does not give exact values..top does not give persistant values..psstat,vmstat..does njot...

Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

$ prstat -a

Hi,
I am a weblogic Admin
I our env there are 5 servers running in one Solaris 10 Sparc machine.
But when i tried for process status using <top> command
I got the following output
load averages: 1.75, 2.18, 2.12; up 134+08:28:49
22:24:21
79 processes: 77 sleeping, 1 running,... (1 Reply)
We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 Replies)
Hi All,
It may be a n00b question, but i really want to know , How Entitled Capacity is less and Used CPU is more when there is no Free CPU is available in the managed system.
I have 5LPARs in a MS with Dual VIO.
Managed System CPU details
Available: 0.20
Assigned to partitions: 15.80... (11 Replies)
I read that Entitlement CPU should be set to max 75% compare to Virtual CPU. May I know the reason.
I have set the Entitlement CPU = Virtual CPU on AIX . It works fine .
Can you help to understand. (1 Reply)

cpuctl
CPUCTL(8) BSD System Manager's Manual CPUCTL(8)NAME
cpuctl -- program to control CPUs
SYNOPSIS
cpuctl command [arguments]
DESCRIPTION
The cpuctl command can be used to control and inspect the state of CPUs in the system.
The first argument, command, specifies the action to take. Valid commands are:
identify cpu Output information on the specified CPU's features and capabilities. Not available on all architectures.
list For each CPU in the system, display the current state and time of the last state change.
offline cpuno Set the specified CPU off line.
Unbound LWPs (lightweight processes) will not be executed on the CPU while it is off line. Bound LWPs will continue to be
executed on the CPU, and device interrupts routed to the CPU will continue to be handled. A future release of the system
may allow device interrupts to be re-routed away from individual CPUs.
At least one CPU in the system must remain on line.
online cpuno Set the specified CPU on line, making it available to run unbound LWPs.
ucode [file] This applies the microcode patch on all CPUs. The default filename is used if no filename is specified. The identify com-
mand prints the installed version on that CPU. On success the identify command show different ucode versions before and
after this command.
FILES
/dev/cpuctl control device
/libdata/firmware/x86/amd/
The directory to install the microcode file for AMD CPUs into. The default filename is microcode_amd.bin for CPU families 0x10
to 0x14. The default filename is microcode_amd_famXXh.bin where XX is the CPU family starting with 15 (hex). Get it from
http://www.amd64.org/support/microcode.html
EXAMPLES
Run
cpuctl identify 0
and you should see something like this:
cpu0: UCode version: 0x1000080
After applying the microcode patch with
cpuctl ucode
you can see with
cpuctl identify 0
that the patch got applied:
cpu0: UCode version: 0x1000083
SEE ALSO psrset(8), schedctl(8)HISTORY
The cpuctl command first appeared in NetBSD 5.0.
