Disabling the open database while flashback?

On Oracle 10.2.0.4


I know that to mount the database before enabling the return of flame. You can disable flashback record while the database is open? Or should it be closed?

We encounter performance problems related to flashback buf free by RVWR and want to do without any impact on customers

Thank you very much

  • Disable the opening of PDF files in the browser.

    Hi guys,.

    I'm deploying DC to my environment, but only one requirement is disable the opening of PDF files in I.e.

    The only work to date is to * manually * disable the Adobe PDF Reader add-on in IE11.

    I tried:

    1. GPO to disable Adobe PDF Reader. The add-on comes as disabled, but a PDF file will always open in IE.

    2. the HKCU entry for bBrowserIntegration = 0. It makes no difference.

    The second step is the only one I've ever used for reader XI and it satisfied my needs. Someone at - it run in this yet? It's really weird that manually disabling the addon works (all PDFs pop out of drive) but if I re - enable and disable then via GPO, the opening of PDF files in the browser.

    Hi christopherh31260325,

    Please provide detailed information about your question.

    Could you please try to uninstall and reinstall MS Reader from the link mentioned below:

    Adobe Acrobat Reader DC install for all versions

    Then, try to disable the opening of PDF files in the browser after you follow the instructions as indicated in the link of doc KB:

    Reference: Acrobat Help. Display PDF in browser. DC to Acrobat, Acrobat Reader DC

    Let me know if it helps.

  • How can I disable the 'Open with' window that appears whenever I start?

    My desktop pc using Windows 7 Home Premium. For years, I want to start with nothing default opening. Each time, the choice of what to open were made manually by me.

    For some reason that I don't understand, one day after start-up, this 'Open with' window appears. Under "Choose the program you want to use to open this file," the indicated file was my name. (I replaced the one here with the word "Me.")

    I never asked this window will open after startup. It appeared for the first time without having done me anything. I do not think that I have all the files with my first name only, so I closed the window and ignored.

    But the window open whenever I start. Don't need or want to be, I keep closing and ignore him.

    Soon, not one, but two of the pop-up appeared. Then THREE.

    For several years, the three windows double as above appeared whenever I start.

    Don't know how or why it began. Don't know which program is causing it. Don't know how to stop it.

    Anyone recognize this window? Do you know which program is causing it to appear after startup? Do you know how to disable? Is there a trick to disable three of them?

    (1) is the window 'Open with' above now a default pop-up window after startup that cannot be disabled without the registry editor?

    No, the "open with" isn't a local default value.  You see it because something - probably malware - tried to configure your computer to start a process at startup time.  Windows, however, does not recognize the name of the process (i.e. the file name) as an executable program so it asks you to specify which program to use to open the file.

    No, you don't need to manually edit the registry to resolve this problem.

    (2) there is no program in Control Panel I can open that has a simple toggle to turn it on or off?

    No, there is no program in Control Panel you can use to solve this problem.

    Here's how fix you the problem.

    A. the easy way (doesn't unless you are very lucky)

    • Click the start ORB, all programs and then scroll down until you find "Startup" and click on it.
    • If you see that anything that gets filed that you do not want to start when you log on to "Start", right click and delete.
    • If you do not know what the items listed and are reluctant to delete something you don't understand not (a very good policy to follow), list all the elements in your next reply and someone here will try to advise you.

    B. the way a little harder (that almost always works)

    • Download here Autoruns.zip (this course is that you download from a Microsoft web site)--> http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
    • Right-click on the downloaded file and select "extract all".
    • Go to the folder where the extracted files are located (this should have been opened for you by default), and then double-click on autoruns.exe
    • Wait until the program has finished scanning (look at the bottom left corner) and then select the 'connection '.
    • Look in the column titled 'Image path' for a line that includes whatever it is that appeared as the 'file' in the original pop-up window.
    • If you find a line with the same name in there, uncheck the box at the left end of the line, close Autoruns and restart your computer.
      • If the ToolTip no longer displayed, you can (a) do nothing do or Autoruns (b) re - run, find the line you're not controlled and right click > delete it.
    • If you cannot find a line with the name you're looking for...
      • Click on the "all" tab
      • Click file, and then click search, then enter the name and click "next".
        1. If a line is found, right click and select 'copy '.
        2. Paste the line in your next reply here
        3. Press F3 to find the next instance and repeat steps 1 and 2 until no more bodies are found (if there are several rows, you can open a Notepad window and paste the lines temporarily here)
        4. If you are reluctant to publish anything with your name in it, change the lines to replace your name

  • Satellite A350-how to disable the speaker internal while external speaker jack

    Hi all

    Anyone knows how I can cut the House speaker while connecting to the external speaker?
    I want to use my laptop in libuary, but when I plug in the headphones, the speaker still his, when I put in muted, the speaker and the headphones the two silent.
    How can I configure the silent speaker, while external speakers can only keep silent?

    > Knowledge how can I mute the speaker internal while connecting to the external speaker?

    I guess you have a Realtek sound card and Realtek HD audio Manager should appear in Control Panel.

    Please check this Realtek HD audio Manager.
    The speakers on the right tab, you will see the options analog & digital.
    Right click one of the option and check if you could see a few options that provide a framework in order to mute the speakers.

    You will also see the option called: the advantage of the device settings.
    Check this box too.

    PS; my laptop automatically the internal speakers if the headphones have been connected.
    I read in other threads that update the audio driver might help too, but first test the settings as mentioned above.

  • Catproc.SQL and Catalog.sql run by mistake in the production database while the database is running.

    Hello

    DB version: 10.2.0.4.0 cluster db. EA

    by mistake one of our dba ran CATPROC.sql and CATALOG.sql scripts in our live production rac database.

    After that issues rose and developers face invalid objects. We erased our users manually main invalid objects and it looks like everything is working well for the moment.

    BUT when I checked object invalid status, he showed me some 600 disabled objects. I'm afraid in the future will come from unacceptable errors.

    What should do? any suggestions? are we in danger? What are workarounds.
