Configuration of 10g to use more than 1 CPU

Hello experts,

I have server Oracle 10.2.0.4 Enterprise Edition running on a Windows Server 2003 - Enterprise 64-bit.

* The server has 4 Xeon processors *.

We have a performance tool that we alert to an enrichment of the CPU.

It seems that Oracle uses only a SINGLE processor.

Is this normal in a 4-processor server?

Can I make a configuration change to allow Oracle to use more than 1 CPU a CPU?

Thank you very much. John

You have several active sessions simultaneously (i.e. normal operation OLTP) relatively fast SQL statements running? Or if you use with a handful of active sessions that each runs relatively long SQL statements (i.e. normal DSS / operations data warehouse)?

Unless you explicitly prevented Oracle to use several processors, it will use Fortunately each processor on the server. But if you have only one session active at a time and that the session is not running of the parallel operations, you would only end up using one of the available processors.

  • Slow Server 2008 performance when you use more than 1 CPU - bug?

    Hello

    It seems that when I run Server 2008 on one of my boxes 3 10.5.7 if I use more than 1 CPU in the settings, the ankles of machine the CPU while booting and then during the use of the operating system.  Normally, I have to run all 3 of them at the same time... and if I get all 3 virtual machines running, the CPU remains just pegged and slows down the machine.

    Then, if I close everything and change the settings to 1 CPU, virtual machines work fine, the CPU barely sees any activity and 75% of the 8 GB is used and it can run for weeks at a time without any problem.

    VCPU more inside a virtual machine using could be a big problem, if you don't have much physical basis.

    If you set vCPU # = # pCore, then you will have several performance issue, cause you VM hangs (during its run) ALL of your hearts.

  • How to use more than 5 esxi hosts?

    If I try to use more than 5 guests esxi, that io parser gives a hint to use an other Analyzer io controller VM.

    So does that mean I have to use two io parser controller vms, i.e. to two Web sites that are not in sync?

    Page 6 of the IO parser guide:

    Maximum Configuration Analyzer of e/s

    Analyzer IO 1.5.1 has been tested up to the following configurations:

    With up to 128 worker virtual machines per ESX/ESXi host.

    With up to five ESX/ESXi hosts by controller i/o parser VM.

    To run the Analyzer of i/o tests with more than five ESX/ESXi hosts, we recommend using several VMs controller.

  • Can I use more than one flash drive to ready boost on Satellite L650/0ed

    Hello

    I have a toshiba Satellite L650/0ed, it's good if I use more than one drive 8 GB flash for "ready boost" - what is the maximum number of using flash-drives can devote to the "ready-boost.

    In addition, if I use a 16 gb flash drive, will this affect more memory "ready boost".

    Why the 3.5 drive seagate expansion 1 TB is not compatible for ready-boost.

    Thank you
    -Brent907

    Hi mate

    Please check this Microsoft page that describes the ReadyBosst
    http://Windows.Microsoft.com/en-us/Windows7/products/features/ReadyBoost

    There, you can find this statement:
    + ReadyBoost works with storage devices more flash. In Windows 7, it can handle more memory and even multiple devices * eight *, for a maximum of 256 GB of additional memory. +

    I hope this can be useful!

    It's only 8.3% of disk space!

    http://digital.NI.com/public.nsf/allkb/E7E2F5657B6026358625750B007201A6?OpenDocument

    The national Instrument is reformat that you drive less than 126 GB or replace the drive with a less than this size.

    Please OR tell me you go fix your LabVIEW Real Time soon, and that we will not have to wait for LabVIEW RT 9.2.1 in 2011 for this one to fix.

    http://upload.wikimedia.org/Wikipedia/Commons/9/90/Hard_drive_capacity_over_time.svg

    Readers as high as 126 GB or more have been around since mid-2002.  It's about 7 years now and LabVIEW Real-time STILL cannot use greater than 126 GB drives!  Please OR.  Do something.

    We deserve the patches for older versions of LabVIEW RT.  What about updates to LabVIEW RT.  As 7.0.2 7.1.2 7.6.2, 8.0.2, 8.2.2, 8.6.2.

    We don't need new features or versions of LabVIEW RT as 9.0 until we have some of the bugs fixed in existing versions.

  • How to activate my MSF program for I could use more than 30 minutes at a time

    I had to uninstall my Microsoft Flight Simulator X and MSF - program of acceleration of my PC and reinstall them.  I did it.  When I installed FSX-Deluxe edition, the program asked me the activation number, I gave and then reinstalled the acceleration program. He asked for all the numbers, but now when I run the program, it suits me after 30 minutes then and asks for the active program.  I tried to use the Enternet and everything, but I can't well any place where I can activate this program.  I even call your hotline, they were of no help at all.  First I did not understand that you are Tech. He talked so fast and has no sense at all.  My question is: How can I activate the program? without going to halfway around the world to do. I never had this problem in the past, why now?

  • Using more than 2 points of control in Interpolater.Spline

    Hello

    what I'm getting is a bouncing ball, I thought it could work controlling the interpolator to create a control of several points using the spline. (a feature of x ^ n ^, where n is the number of control points)
    In a Groove I can use only two control points, is there a way to use more than that, or do I have to use another way.

    Thanks for any help.

    Well, I guess it was not so difficult - at least when there are libraries written by others to borrow to...

    The interpolator requires the apache commons math 3.2 lib - you can download Commons-math3 - 3.2 - upload - the here:
    http://Commons.Apache.org/proper/Commons-math/download_math.cgi
    Remove Commons-math3 - 3.2.jar since the zip and put it on your class path.

    The interpolator differs slightly from the interpolator of Interpolator.SPLINE that comes with JavaFX.
    Instead of control points which bend the curve but do not lie on the curve, the interpolator takes a set of points and trace a straight regression line through the points.

    import javafx.animation.Interpolator;
    import org.apache.commons.math3.analysis.interpolation.SplineInterpolator;
    import org.apache.commons.math3.analysis.polynomials.PolynomialSplineFunction;
    
    public class BestFitSplineInterpolator extends Interpolator {
    
      final PolynomialSplineFunction f;
    
      BestFitSplineInterpolator(double[] x, double[] y) {
        f = new SplineInterpolator().interpolate(x, y);
      }
    
      @Override protected double curve(double t) {
        return f.value(t);
      }
    }
    

    Here is a usage example:

  • How to use more than one address at the same time?

    The Adobe server page that allows entry of a recipients address should not inform users how to add another address?  We separate them by semicolons? Commas?  Or is it still possible to use more than one address?

    Hi orison123,

    You talk about Adobe send? If Yes, you are absolutely right. Who should be written somewhere I had to double check and was able to send to multiple email addresses separated by commas or semicolons.

  • 2 questions: backups of disk XP and EULA talk about more than 1 CPU.

    2 questions: The Windows XP Home EULA says that I can not use the program on more than one CPU. Does this mean that I am breaking the agreement by running on a dual-core CPU? Second question, it is good to re - install Windows XP from a backup copy, when I lost the original disk but still have a valid product code?

    First question: a dual-core CPU has two processing cores, packaged in a single module.  It counts as a single processor for Windows XP license.

    Second question: Yes.

  • Cannot start a virtual machine with more than 1 CPU socket added

    I've set up a few boxes of ESXi 5.5 with the free license in recent weeks, they have all been without problems so far. All 4 servers have the same exact hardware

    Environment:

    Dell Poweredge T620

    E5-2630 2 Intel CPU

    40 GB OF DDR3 ECC RAM

    ESXi is installed on 2 x 146 GB 15 K SAS drives RAID-1

    Data for virtual machines store are 8 x 600 GB 10 K SAS RAID-10 disc

    Guest operating system is Server2012r2 on all virtual machines

    Installed it on ESXi 3 previous were conducted with custom ESXi 5.5 Dell without problem.

    The 4th is where I will have questions. I used the following ESXi installed just in case there is a bug somewhere

    5.5 of VMware ESXi

    ESXi 5.5 customized by Dell

    5.5 U1 of VMware ESXi

    Any version of the ESXi I use I can't have a virtual machine to begin with more than 1 CPU socket added to it. The virtual machine does not start even the VMWare BIOS. I tried the Bios EFI as well with no luck. The error message I get in the events is ' fatal error VMware ESX: vcpu (vcpu-X)-X:VM - entry failed; Valid VMCS (error code 8). The vcpu-X is always another. I have attached the log file is created. If I give the VM 1 single processor TI starts very well. I'm at a loss as to what could be the issue.

    Problem is solved. I caught another server with identical hardware, verified it worked properly, then started to swap parts between them. Turned out to be CPU1. Once this has been replaced from a working server I have not had any problems. Warranty has been appealed.

    Thanks for all the help!
