You need to also list how many Virtual CPUs an LPAR has to understand this.
If an LPAR doesn't use it's entitled capacity is donates it back to the pool and can be allocated to other LPARs based on need and weighting. so although it's entitlement may be quite low, the server finds and reallocates unused processor time, so the situation you describe is very common.
The best way - In my opinion - to see what the CPU on an LPAR is doing is to use the
command and look at the ent% column as this shows how much CPU the LPAR is using relative to the entitled capacity.
Entitled Capacity means that the LPAR is guaranteed to have that amount of CPU available to it, and that is what the Assigned to Partitions number means, is the sum of all entitled capacities for LPARs in the server.
Hi..,
my dout is a solaris server is having 16 cpu's.
in tht one cpu running some error process, accupaying more space.
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.

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

Hi there,
I'm in the process of choosing a machine to be a server and I was wondering how to interpret CPU description.
Example1:
Intel® Pentium® G6950, 2C, 2.80GHz, 3M Cache
I understarnd there are 2 cores, each running at 2.80 GHz.
Example2:
Intel® Core™ i3-530, 2C/4T, 2.93GHz, 4M... (4 Replies)
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
i have 2 esxi. one is amd based cpu and the other is intel based cpu.
i have a redhat linux machine that was created in amd cpu esxi, now i need to migrate it (powered off) to INTEL based esxi. will the redhat machine will be OK with that?
Thanks (2 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)

psrset
PSRSET(8) BSD System Manager's Manual PSRSET(8)NAME
psrset -- control processor sets
SYNOPSIS
psrset [setid ...]
psrset -a setid cpuid ...
psrset -b setid pid ...
psrset -c [cpuid ...]
psrset -d setid
psrset -e setid command
psrset -i [setid ...]
psrset -p
psrset -r cpuid ...
psrset -u pid ...
DESCRIPTION
The psrset command can be used to control and inspect processor sets.
The system always contains at least one processor set: the default set. The default set must contain at least one online processor (CPU) at
all times.
Available options:
-a Assign one or more processors (CPUs) to the set setid. In the current implementation, a CPU may only be present in one set. CPU IDs
are as reported and used by the cpuctl(8) command.
-b Bind one or more processes to the set setid. All LWPs within the processes will be affected. Bindings are inherited when new LWPs
or processes are forked. However, setting a new binding on a parent process does not affect the bindings of its existing child pro-
cesses.
-c Create a new processor set. If successful, the ID of the new set will be printed. If a list of CPU IDs is provided, those CPUs will
be assigned to the set upon creation. Otherwise, the set will be created empty.
-d Delete the processor set specified by setid. Any LWPs bound to the set will be re-bound to the default processor set.
-e Execute a command within the processor set specified by setid.
-i List all processor sets. For each set, print the member CPUs. If psrset is run without any options, it behaves as if -i were given.
-p List all CPUs. For each CPU, print the associated processor set.
-r Remove a CPU from its current set, and return it back to the default processor set.
-u Bind the specified processes to the system default processor set.

The psrset command first appeared in NetBSD 5.0.
