Determine the CPU utilization

Guys,
I've been asked to determine the CPU utilization for the execution of my procedure performing a large ETL operation. (in an unix box)
Could someone help me out?..Is there an oracle query with which I can find the detail?
Thanks guys!!!
Regards,
Bhagat

Compare CPU statistics before and after proc execution. They are measured in 10s of milliseconds.
select sn.name, ms.value
from v$sesstat ms, v$statname sn
where ms.statistic# = sn.statistic#
and upper(sn.name) like '%CPU%'
and ms.sid = [proc session SID]Regards,
Dima

Can't get the CPU utilization above 52%

Hi all,
I have an Intel i7 950 CPU based PC with Windows 10 TP on it which, no matter what, I cannot bring to 100% CPU utilization. While taking the attached screenshot, I was running prime95.exe.
I have tested the same scenario on the same computer running Windows 8/8.1 and got the same result. However, when doing the same thing under Windows 7, CPU utilization went up to 100%.
Anybody has any idea why this happens? Is it a different default setting somewhere (probably in registry)?
Since I have this fast machine I would like to be able to use it at its full strength - the way things are now, my old Quad core 2 GHz PC is MUCH faster than this 8 core 3 GHz one (as I measured in several tests consisting of transcoding videos).
Thanks for any pointers!

Hi VikTak-9b,
How did you get the CPU utilization information ?Are you getting the information from the task manager ?

I am a little confused here .According to my understanding ,the number is smaller the performance of the machine is higher when the other conditions are the same .
Here is a link may be useful for us to understand the CPU Utilization for Performance Analysis

Finding the CPU Utilization of a client.

I am doing a ptoject in grid computing.
Here one server connects to several clients simultaneously using multithreading concept.
I have to determine the CPU Usage of each of the clients connected to the server. Can anyone suggest the source code for that?

java.lang.management.ThreadMXBean has methods for getting CPU time of a thread. Exists in JDK 1.5 and upwards. May not be supported in all operating systems / JVM's, write a quick test first to see if your system supports it. Google might find examples.

The CPU utilization is 0% for the other remaining processes when multi threading is used

I am new to AE ,so I am trying to render a project enabling multi threading process the additional processes are present but their utilization is 0% .
I want to juice out every single CPU utiliaztion .
ANy help is greatly appriciated,.
My system specs:
AMD 9690 4.7 Ghz 8 core
32 GB DDR3
C:\256 GB Solid Satte Raid 0
GeForce 780 Ti DDR5 3GB

It is very tempting to try and use all of your system resources and multiprocessing for all your projects, but this is not the way After Effects works. Many third-party plug-ins, many codecs, and many operations do not respond well to multiprocessing. All it takes is one process in your entire thread that is not MP aware to foul the whole thing and give you longer render times.
You are also leaving zero processors for the rest of your computer. Not a wise idea.
After effects renders one frame at a time. One HD frame even with multiple layers of pixel processing just isn't that much data. It does take a while to do the calculations, but expecting to have every one of your CPUs jacked up at 100% to render a single frame of video is expecting an awful lot.
I would suggest that you read up on optimizing After Effects for your computer. Do not expect to be able to utilize 100% of your system resources at all times. That's just not the way processing video on a pixel by pixel basis works.
Just a little FYI, for 99% of my projects in After Effects I have render multiple frames simultaneously turned off. It just doesn't work with most of the things I do. Sorry for the disappointment.

How is GC cpu utilization % calculated?

I am trying to find a way to capture the problem where a user process eats up a ton of cpu for over 30 minutes. I thought that I could possibly use the cpu utilization metric.
In testing it, I reset the values to warning and critical thresholds to 0 and 5% respectively to see what would happen. I was emailed with the expected critical alert. In looking at the top sessions on the server, I noticed that 1 session was eating up 100% of one cpu (which I want to know about) but the alert email said that 45% was utilized which I noticed was about what the user load is on the server.
Initially, I had the warning and critical threshold set to 85 and 95% respectively but did not get any warning about a user process that was taking up 100% cpu for > 5 minutes (in which the 5 minute collect times were set to once).
My questions are
1) How do I capture a single process eating up > 90% cpu in a multi-cpu environment
2) Is the cpu utilization % capturing the Average Load of the cpus on the server and alerting when it's above the critical threshold?
3) How is the cpu utilization % calculated?
Help would be appreciated.

The cpu load is determined by running the Grid program nmupm found in $AGENT_HOME/bin
The output is like:
dbc12ykf: PDBGRP> nmupm osCpuUsage
em_result=1|206331806.000000|201540370.000000|102524043.000000|958620752.000000
em_result=2|212731589.000000|201203614.000000|67775500.000000|948506267.000000
em_result=3|212402913.000000|230642957.000000|76833167.000000|917779040.000000
em_result=4|242543014.000000|367865067.000000|81554006.000000|791426607.000000
You will get a line for each cpu.
YOu'll need a bit of reverse engineering to figure out the columns - I think they are user, system, idle , 5min avg - Multiplied by 10000 ?
Now to capture a big one - I think you will need a user defined metric. Just write a simple shell script to run the above command, and evaluate the numbers coming thru.

High CPU utilization with JDesktopPane.OUTLINE_DRAG_MODE

Hello there,
since I updated from Java SDK 1.4.0 to 1.4.1_01 I recognized a problem with MDI Java applications using a JDesktopPane with JInternalFrames. When the drag mode of the internal frames is set to OUTLINE_DRAG_MODE, which should have a better performance than the LIVE_DRAG_MODE the cpu utilization goes nearly up to 100% an the drag of the frame is quite slow.
Does anybody else experience this problem?
(The problem exists in the application I develop and also in the IDE Netbeans, I use for development)
I am not sure if this is the right place for my problem, so if there is a better one to post it to, please tell me.
Thanks

CPU utilization problem with JSF

Hi,
I am using MyFaces 1.1.4 and tomahawk 1.1.3.
I am using EJB 2.0 and weblogic server 9.2
I have a problem with the performance of my application. The response time for 500 concurrent users is arnd 10sec. However, the CPU utilization normally hits *95-97%.*
I have disabled all the logging to reduce the file IO. Also, all the code has been optimised. Still the problem exists. Now, I cannot think of any way to overcome this. My project is getting delayed because of this.
Request you all to pls help.
Regards,
Milan.

What type of server or servers are you using. I am assuming which I hate to do is that your EJB's are for CRUD and you a connection pool. Have tried to optimize the DB connection pool's ?.

Performance degrading CPU utilization 100%

Hello,
RHEL 4
Oracle 10.2.0.4
Attached to a DAS (partition is 91% full) RAID 5
Over the past few weeks my production database performance has majorly degraded. I have not made any application, OS, or database changes (I was on vacation!). I have started troubleshooting, but need some more tips as to what else I can check.
My users run a query against the database, and for a table with only 40,000 rows, it will take about 2 minutes before the results return. For a table with 12 million records, it takes about 10 minutes or more for the query to complete. If I run a script that counts/displays a total record count for each table in the database as well as a total count of all records in the database (~15,000,000 records total), the script either takes about 45 minutes to complete or sometimes it just never completes. The Linux partition on my DAS is currently 91% full. I do not have Flashback or auditing enabled.
These are some things I tried/observed:
I shut down all applications/servers/connections to the database and then restarted the database. After starting the database, I monitored the DAS interface, and the CPU utilization spiked to 100% and never goes down, even with no users/application trying to connect to the database. The alert.log file contains these errors:
ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code arguments: [ttcdrv-recursivecall]
ORA-03135: connection lost contact
ORA-06512: at "CTXSYS.SYNCRN", line 1
The database still starts, but the performance is bad. From the error above and after checking performance in EM, I see there are a lot of sync index jobs running by each of the schemas and the db sequential file read is high. There is a job to resync the indexes every 5 minutes. I am going to try disabling these jobs tihs afternoon to see what happens with the CPU utilization. If it helps, I will try adjusting the job from running every 5 minutes to something like every 30 minutes. Is there a way to defrag the CONTEXT indexes? REBUILD?
I'm not sure if I am running down the right path or not. Does anyone have any other suggestions as to what I can check? My SGA_TARGET is currently set to 880M and the SGA_MAX_SIZE is 2032M. Would it also help for me to increase the SGA_TARGET to the SGA_MAX_SIZE; thus increasing the amount of space allocated to the buffer cache? I have ASMM enabled and currently this is what is allocated:
Shared Pool = 18.2%
Buffer Cache = 61.8%
Large Pool = 16.4%
Java Pool = 1.8%
Other = 1.8%
I also ran ADDM and these were the results of my Performance Analysis:
34.7% The throughput of the I/O subsystem was significantly lower than expected (when I clicked on this it said to either implement ASM or stripe using SAME methodology...we are already using RAID5)
31% SQL statements consuming significant database time were found (I cannot make application code changes, and my database consists entirely of INSERT statements...there are never any deletes or updates. I see that the updates that are being made were by the index resyncing job to the various DR$ tables)
18% Individual database segments responsible for significant user I/O wait were found
15.9% Individual SQL statements responsible for significant user I/O wait were found
8.4% PL/SQL execution consumed significant database time
I also recently ran a SHRINK on all possible tablespace as recommended in EM, but that did not seem to help either.
Please let me know if I can provide any other pertinent information to solve the poor I/O problem. I am leaning toward thinking it has to do with the index sync job stepping on itself...the job cannot complete in 5 minutes before it tries to kick off again...but I could be completely wrong! What else can I check to figure out why I have 100% CPU utilization, with no users/applications connected? Thank you!
Mimi

Tables/Indexes last analyzed today.
I figured out that it was the Oracle Text indexes synching to frequently that was causing the problem. I disabled all the jobs that kicked off those indexes and my CPU utilization dropped to almost 0%. I will work on tuning the interval/re-enabling the indexes for my dynamic datasources.
Thank you for everyone's suggestions!

How to reduce CPU utilization time in Java Application

Hi,
I have created a Java Application. It is a 3-tier architecture. While running my Java application, the CPU utilization percentage shots up to 100 %. I feel that it will affect the system performance and it will hang up the system also.
If any body know the solution to reduce the CPU utilization or links, please post it.
Thanks in advance.

I know Java class file must be interpreted by VM. but
Visual Basic is also a language to be interpreted. Why
it run faster than Java? As Java running speed is
concerned, it's unwise to apply to the
enterprise-level application. Now I can't endure Java
running speed. I wander to know whether it is
associated with operating system or not.1. Java is nto interpreted in modern (since 1997 or earlier) JVM's - it is compiled into machine code as it is executed via a JIT or a Dynamic compiler (like HotSpot).
2. VB (5 and later) is also not truely interpreted - in fact it uses the same excellent native code generator used by Visual C++.
3. Java is principally used these days for enterprise server-based systems where it performs extremely well - or extremely poorly as does C++ in the hands of people who don't know how to use it.
4. Different JVM's (and in some cases the same JVM hosted on different OS's) perform at different speeds - your mileage will vary. The OS has little influence on the computational speed of java but can highly influence its network, disk and graphics performance, as does hardware configuration (local console versus X terminal - Swing sucks on X Term).

How to measure CPU utilization from Oracle AWR

Hi All,
How to measure the cpu usage % from the AWR reports.
Oracle : 10.2.0.3
OS : AIX 5300-12-02
I see the top 5 waited events listing CPU time in it.
Top 5 Timed Events Avg %Total
~~~~~~~~~~~~~~~~~~ wait Call
Event Waits Time (s) (ms) Time Wait Class
CPU time 98,655 40.0
Is it mean that the CPU utilization is full to its 100%. Is there any other way to measure how much an oracle instance is utilizing the CPU ?
Please advice.
TIA,
