Session of forms taking a lot of CPU to R12

Hello

There are in our production server of the EBS R12 session of forms that take a lot of cpu on nodes which increases CPU load to 99%.

The part of command topas shows the following o/p
Name            PID  CPU%  PgSp Owner           PageIn        1  PAGING SPACE
frmweb      1233124  24.1  32.1 applprod        PageOut       3  Size,MB   24576
frmweb      1691786  23.7  38.3 applprod        Sios          5  % Used      0
java        1085558  22.5  41.0 applprod                         % Free    100
frmweb      1540104   0.6  29.6 applprod        NFS (calls/sec)
frmweb      1351684   0.4  44.5 applprod        SerV2         0  WPAR Activ    0
When I try to find the corressponding session in the node (node 2 CARS) of the database using the
select inst_id, sid from gv$session where process='1233124';
So I have to kill these forms (kill-9 1233124 in above case) session to reduce load


I know that this is not normal. Depending on the configuration of the server, we have:

Database: Database 11g (11.2.0.1.0) on node 2 RAC
Application: 2 node R12 (12.1.2)
Operating system: Aix 6.1 power

Kind regards

  • Flash uses a lot of CPU

    I don't know when this started, but recently whenever I visit Web sites that use some or a lot of Flash, Firefox slows down completely. When I went in my task manager, I saw that FlashPlayerPlugin.exe was using a lot of CPU (109, 396 k to be exact). Actually, there are two open process. In the past I've never seen these before in Task Manager, but now it is a problem. Any ideas?

    Nevermind, I found a solution. It seems that there is a new feature implemented by Flash called Protected Mode. To disable it, you must go to C:\WINDOWS\Macromed\Flash then open a text called mms.cfg file and add the following text: ProtectedMode = 0. To disable.

  • What is superfetch? Its in my sTask window manager and he uses a lot of CPU power... .do I need it and what is?

    The program is placed in my Windows Task Manager and takes a lot of CPU power, and I wonder what use it perhaps can cause? my CPU usage was 100% and my antivirus uses only 5%.

    "Superfetch" and "The host Windows Services" take so much CPU power on i3, 3 gb Sony Vaio!

    SuperFetch is a Windows service that is designed to accelerate the launch of the app by preloading some applications based on your usage patterns. Tune-up blog has a good explanation of what it does.

    However, it should not be maxing out your CPU all the time. If it slows down your computer, you can try to disable it.

    To turn off:
    Open the Start Menu.
    Type "services" and press ENTER.
    SuperFetch. search in the list and right click > properties
    Set the startup type to disabled, and then click the Stop button to stop the service
    Click Ok

    You want to make sure that your antivirus software is up to date and your computer is clean.

  • Firefox using a lot of CPU (90% + sometimes)

    I use firefox version 26.0 on a Macbook Pro OS X 10.6.8 version and I run these http://i.imgur.com/Co4NlGQ.png and http://i.imgur.com/Co4NlGQ.png extensions. I'm also using these plugins http://i.imgur.com/ZO55Lmq and http://i.imgur.com/IapcvJY and I have disabled all plugins, and which has not helped because the CPU usage always fluctuated close to 10% all the way up to 100% usage.

    I checked to see if the plugins are up to date and I updated one of them, but the most recent update of Java Applet Plugin works only with Maverick, which I did not. QuickTime said it is not up-to-date, but when I checked the software update on my Mac, it says there is no update available.

    Image of the plugins I checked to see if they were updated http://i.imgur.com/fPuV8vD and http://i.imgur.com/7Uwp5vX and http://i.imgur.com/N0Cz9Tp http://i.imgur.com/6FIwVTv aaand.

    Here is a picture of my activity monitor (I got all plugins disabled here) http://i.imgur.com/j6xUudo . As you can see, the CPU usage is 99.6%, which is huge given only, I opened a webpage (reddit) and was not running videos and others. And here's a picture of my activity with more information http://imgur.com/zuY5iMu monitor. The real Mem can go all the way up to 2 GB, which is a bit worrying.

    I tried to reset Firefox, which did not help, I tried from FF in safe mode, which did not help, and I even tried to reinstall FF, that did not help. I also tried disabling "using hardware acceleration", restarted my computer, and the issue was not fixed. I used CCleaner to clear temporary files and other, but it won't do any good.

    I really want to be able to use Firefox, because I'm starting to be wary of Chrome, but if FF only use a lot of memory and CPU, I'm not sure that I can continue to use this browser.

    I feel I hit dead ends on everything I tried, so I'm starting to lose hope. Did someone help any idea or suggestion as to what I should try / do?

    I have never seen that, perhaps, simply a reset will fix all the problems.

    NOTE that RESET WILL NOT:

    • Delete bookmarks, saved passwords, Form Data, history, tabs open (if you use Firefox 25 and more).

    A discount to ZERO will BE:

    • Delete the Addons, Custom Prefs, Configurations of toolbar, search engine settings

    More on reset (and how to achieve it) can be found here.

    If you want to be safer, you can save your profile (its likely will not be necessary)

  • Download a file through the sessions of form in R12.1.3

    Hello

    We have a customer with R12.1.3


    Now my doubt is if I download a file via a form session, where this file will be saved to the backend [server-level]

    Thank you
    Shaik

    I have some doubts in the Doc 294525.1 MOS as below:

    file://y:/attachments/Heather.jpg
    The latter refers to a network drive mapped, on the client PC. Before use, the 'y': on the client has been mapped to a shared folder on a server. Because him 'y' will be saved in the form of an attachment, all client machines must refer to this as "Y:" share point or whatever letter society commonly selects for this shared network resource.

    This means that we must keep the documents physically mapped device and need to save the situation at the level of the application?

    We can download or open documents from oracle apps via a device mapped to our local machine?

    It is to use a network drive to store files (server of different file that isn't your web layer node) and this reader should have the same mapping on all clients (Y:\ or Z:\), this cannot be mapped as Y:\ on a single client and Z:\ on another client.

  • Exec.vi "Wait until completion" system uses a lot of CPU. Help

    I am writing an application that calls parallel instances of an external program. I have the code of work to run the EXE file with the Exec.vi system. When the completion up to wait entry is set to true on Exec.vi LabVIEW system uses all my CPU. The EXE I am running is an exe of low intensity, and if I don't wait until completion LabVIEW has no high CPU usage. It would be nice, but I have the code which needs the EXE to finish before moving. I'm doing something wrong? I could not find this behavior as a known issue, so I would like a mental health to make sure I'm not stupid fouls. I have attached a demo that recreates the question. The VI called the EXE with lance Notepad and then updates the text in Notepad. I am attaching the source code of the demo EXE as well.

    Thanks Bob

    LabVIEW sequentially launches 20 cases of "Idel_EXE.exe" who are getting a Notepad and returns information.

    This description is exactly what asynchronous call and collect is supposed to manage.  'Call' treats only the controls, move the VI 'in' data you call.  The "wait on asynchronous Call" does the rest - if the called VI has done and wants to pass 'out' data, this function provides the values.  As I have indicated, if the called VI is still ongoing, wait for asynchronous can expire, return an error (which you can use as a signal 'Wait a little bit longer').

  • in System 32 Spoolsv.exe taking 90% of the CPU usage.

    Original title: spoolsv.exe in System 32

    in my task manager processes, spoolsv.exe exists that uses more than 90 percent of one of my cores of the processor. It is in System 32. I want to know what is it and why it uses 45% of my CPU?
    How can I stop it permanently?

    Hello

    Method 1.
    This happens usually when the printer spooler folder is filled with unwanted files. You can resolve this problem by following the steps below:
    a. go to start, settings, then click Control Panel
    (b) in the Control Panel window, double-click first administrative tools, then Services.
    (c) in the right pane of the Services window, locate and with right-click on print spooler and then select stop.
    d. you have stopped this process, leave the window open. Now open my computer and navigate to the following folder.
    c:\windows\system32\spool\PRINTERS
    e. delete all files in the Printers folder. After you delete the files in this folder, return to the Services window, right-click on print spooler and select start reactivate service.

    Method 2.
    Although the true spoolsv.exe file is a secure, many malicious programs are known to dress up in spoolsv.exe. Sometimes the security program installed might not be fair enough. I also recommend you update your security software regularly.
     
    a. follow the link below to start the free online scan:
    http://OneCare.live.com/site/en-us/default.htm
    b. run the malware removal tool from Microsoft.
