    Hi elizabethu,

    Hello

    you are using IBM AIX PowerHA for your database (active/passive) configuration. then you just install the binaries 'once' on one of the nodes. then coordinate with your operating system administrator to configure the fail the test scenarios.

    for your question. before you start the database, make sure that there are no "orphaned" oracle process using the UNIX grep command:

    $ ps - ef | grep ora

    Kill the oracle of the hanging of the process to release the lock on the database file handle:

    $ kill-9

    I hope this helps.

    Kind regards

  • Excessively the CPU usage high on my Equium M70

    Hello

    Recently in the last month my summer CPU usage hit 100% when I m not running any software tax (only internet explore and windows media player).

    It is slowing down the load time and the area near the fan is hot enough.

    I have a Satellite M70-337, with a 1.7 centrino processor and now 2 GB of RAM (formerly 512 megabytes). I upgraded the ram in December and had no problems like that, now it just started happening recently, I have installed everything that would, there is no unnecessary programs running and it was after I restored my computer to factory with the startup disk settings (a month later), he seems to have come from nowhere. On the list of the Task Manager it shows my web browser and Media Player by using most of the CPU, but I could have sworn that they use so far before.

    I don't know if the RAM would have been a factor, but it was the correct RAM for it and windows recognized to 2 GB.

    Why would it suddenly happened any ideas guys?

    Hello

    I have the same model of laptop and at the moment I have no such problems. To be honest, I did new installation OS 3 months ago and after installing Microsoft Update, I noticed this laptop does not work as before. Just for example: if I use IE7 extensively with several different tabs in the Task Manager I can see this need for IE more than 300,000 k of memory and crashes somehow. After the closure of the IE and ending THE process sin Task Manager I can work normally again.

    I don't really know how your operating system is configured, but in the Task Manager, you should see what running process is responsible for the high CPU usage. Maybe some antivir application? Sorry, but it is really not easy to sayt why this happens. Play around with the current process.

  • What is the "system idle process" and why it seems to freeze my Windows XP and show the 99% CPU usage?

    This problem sometimes occurs when my computer starts. Today, it happened and actually picked up my internet connection, which also won the update of Flash Player and Internet Explorer open. Also, I couldn't get the Start Menu to open. What is happening to the CPU is too busy doing something else? Is there a way to refresh the process or the CPU?

    Hi Hope_H,

    1. did you of recent changes on the computer?

    2 when was the last time it was working fine?

    3. do you have security software installed on the computer?

    4. you receive an error message?

    Checking service or program uses high processor usage by using Task Manager.

    To view the CPU usage, press CTRL + ALT + DELETE, click Task Manager, and then click the performance tab.

    Overview of the Task Manager

    http://www.Microsoft.com/resources/documentation/Windows/XP/all/proddocs/en-us/taskman_whats_there_w.mspx?mfr=true

    It is possible that some third-party programs installed on the computer is causing the problem.

    I suggest that you put the computer in a clean boot state and check if it helps.

    To help resolve the error and other messages, you can start Windows XP by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

    See the link below to learn more about how to clean boot.

    (b) If you are prompted for an administrator password or for confirmation, type your password or click on continue.

    (c) under the general tab, click the Normal startup option, and then click OK.

    (d) when you are prompted to restart the computer, click on restart.

  • When Windows starts it is always a dialogue box that flashes on the screen and the CPU usage high (above 50%), after I connect sometimes for several minutes.

    Original title: at the start of Windows there is always a dialogue box that flashes on the screen, but I've known idea what it is.

    How can I determine which program is using this dialog box? I also don't expect high utilization of the processor (over 50%) after that I connect sometimes for several minutes. I see not all applications running in the Task Manager. The amount of CPU utilization in the services tab doesn't match what I see compared to what the gadget is read in my sidebar. Any ideas?

    Thanks in advance

    Hi Soan,

    1. What is exactly mentioned in the dialog box?

    2. when the problem started?

    3. did you of recent changes on the system?

    Method 1:

    Step 1:

    You can check if the problem occurs in safe mode.

    Start your computer in safe mode

    Step 2:

    If you are not faced with the question in safe mode, you can perform a clean boot and check.

    A clean boot to check if startup item or services to third-party application is causing this issue.

    You can read the following article to put the computer in a clean boot:

    How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

    After the troubleshooting steps, please refer to clean the boot link to put the computer to normal startup mode.

    Method 2:

    You can read the following article and perform a full scan of security on your computer.

    Microsoft safety scanner

    Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss. You can take a backup of important data before performing analysis.

  • Satellite R830-1GZ - CPU usage high (> 25%) and increase in the speed of the fan after reactivation

    Hi all

    The CPU usage of my laptop shoots upward to 25% (and beyond) and increases in fan speed considerably after waking up, but only when I use an external mouse (Microsoft Natural Wireless Laser Mouse 6000) - disconnect the mouse once it happened does not solve the problem, so I always have to restart my computer if I let go sleep with the connected mouse.

    I noticed that when this produces the system interrupts - delayed appeals procedure and Interrupt Service routine appears in the resource monitor > CPU > process and seems to explain the increase in the use of the processor.

    Any ideas on how to solve this problem would be most appreciated.

    I use a Toshiba Satellite R830 1GZ with Windows 7 (64-bit). This problem will not occur when I use the same mouse with another laptop (Dell with Windows XP).

    Thank you very much.

    I think that the process that controls the mouse MS WLan does not close properly.
    The system to memorize it and therefore the cooling module begins to spin faster because these processes stressed the central unit.

    Maybe its caused by the mouse driver
    Have you checked if there is an update to the driver?

  • Problem with the Ubuntu CPU usage

    Hello

    We meet a few the next problem with an Ubuntu VM:

    The virtual machine has 8 vCPU (increased from 2 Sockets with 4-core to 8 outlets with a carrot) and the latest VMware tools installed. Even if there is a lot of load on this system, the virtual machine seems to use about 25% to 50% of CPU capacity. The return of the command vmstat 1 during this time is:

    user: 28%

    system: 4%

    inactive: 78%

    wait: 0%

    VCenter statistics shows a spike on the CPU load, but epi only climbs and rest between 25 and 50 percent or a maximum use of 7 309 MHz (about 16,000).

    Since a thread can use 100% of a vCPU it may be a problem of thread on your application.

    You should look at the use of the individual processor instead of overall consumption.

    Lets say that the application can use only 1 wire but it uses 100%, this means that it will use to 12.5% of the total cpu resources allocated to this virtual machine. (100/8)

  • Flash video jumps despite the low CPU usage

    It is a problem of browser independent (in IE and FF) and apply only to the Flash Video (YouTube, for example)-it happens for example with DivX.

    Time to time the video will drop frames. Running beside the video Task Manager, I see that the CPU actually tends to fall in these moments, rather than boost. Well, it comes down to the departure at the time of the loss of images and then upwards slightly above reference for a short period. Use during playback, however, is very small, about 3-4%.

    What I tried:

    Change Windows high-performance power management

    Deactivation of many processes that run in the background

    Deactivation of the possibilities for energy savings in the energy Manager of Lenovo and technology Intel Rapid Storage Technology (though I doubt that this has nothing to do with the HARD drive)

    Disabling hardware acceleration in Flash

    .. .but does not.

    System information:

    Flash 12.0.0.77

    I have a new Lenovo Z710:

    Processor: 4th generation Intel Core i7-4700MQ processor (2.40 GHz, 1600 MHz 6 MB)

    Device HDD: 1 TB + 8 GB

    It has Intel Graphics HD 4600 running the latest drivers.

    It's a clean new laptop - I did very little with it and actually this problem presented before I did anything for her.

    It is quite frustrating and my old Acer laptop, although usually slow, doesn't have this problem.

    I hope someone can help.

    Hello. I have a similar problem with casual framedrops while watching Youtube videos in point 8.1 of Windows. My processor is a core i5-4440 quad, and I also GMA 4600.

    I think it's a little problem with Flash player multi-threading with quad core CPU. It does not seem to happen when I go in the Manager of tasks and set the affinity for the Flash Player to use only a single core. Try it on your machine and see if it falls still frames.
