How do I empty the buffers

A developer is interested in hunting of the Oracle buffers so that he gets the results of uniform test for its performance tests. In the past, I think I took the tablespaces in offline mode, and then put them online. This invalidates all pages in this space in the buffer, but also interrupts the other process.

If you have an alternative idea, part of means.

What version of Oracle?

In 10g (and), you can issue the command "change the system built-in buffer_cache;". Of course, this requires that the appropriate privileges are granted to the developer.

Why clear the cache? A better measure is the number of I/o logic operations.

  • How can I empty the Windows installation on my hard drive?

    How can I empty the Windows installation on my hard drive, please?  I was going to re - install, then I changed my mind.
    Now, every time that I reboot, instead of launching Windows XP Pro, it try to run Windows installation.  The installation program appears as a second menu item under "Windows XP Pro" on the black screen at launch.

    How can I remove it from the startup screen and flush it out of my system?

    Any correction, automated for this?

    Thank you.

    It is difficult to determine what you did, but the symptoms you describe can be eliminated by editing the boot.ini file (you can also make things really difficult if you make a mistake when you edit the boot.ini file, so be careful).  Will not be "flush out the Windows installation" of your system, but it will stop the menu from appearing at startup time.

    See http://support.microsoft.com/kb/289022

    Your boot.ini file probably has a second line in the [operating systems] section.  Make sure that you delete only the line that points to the installation routine.

    Can Hoow I empty the trash?

    Assuming that the icon appears on the desktop everything you have to do is right click and then click on the empty basket.

    Or open it, click the file menu drop down and then click on the empty basket.

    Once you clear, the files will be permanently deleted. Only specialist file recovery software will recover accidentally deleted files from the bin and even in this case there is no guarantee.

  • How can I empty the organizing items catalogue? I want to start again...

    I want clearly on the catalog, do not delete is not the original image. But I want to import the photos again, because they are now better organized in their source files.

    Better to create a new catalog empty.

    If you have already added captions and ratings, tags, use the file menu to "write metadata to files. These data will be recovered during the 'import' your files again.

    I wonder if you properly use the Organizer. The Organization of the files is a secondary concern; you use categories and keywords/albums mainly. If you want to 'reorganize' your folder tree, you can do from within the Organizer; However, you can do without if you have a correct structure of categories, keywords and albums.

  • How can I empty trash 'Genius '?

    10.7.5, old 32-bit Macbook Pro OSX.

    The Genius bar went yesterday to resolve a problem.  During which, the genius deleted all my music, photos and movies by being connected with a disc of Triage and the magic Apple Genius ID.  He stopped at the command "Empty trash" because he took long (approx. 300 GB of data).  Now, my drive is missing that much space.

    Any ideas how can I empty the Recycle Bin or restore these files?  (Short to return to the Apple store?)

    Thanks in advance...

    You have a backup, if so what kind? It may be interesting to restore if you have a recent backup. Otherwise I would like to backup now if you have a spare drive to use-

    even in this State. At least you have a copy if it fails to restore the Recycle Bin.

    Have what problem you tried to bring to the store? I have to wonder if start over again with a fresh install is a better option?

    It is possible to "put the files"...

    Select an item in the Recycle Bin, right click (or use ctrl + click). In the menu that appears, select 'Put back'. It may not be an option (I don't remember which version added this feature, I think that it was 10.6).

    It is available "back" may not restore all the files and some files may already have been recreated in the old location (existing preferences for example).

    I fear this is can be a messy situation to fix.

    It might be easier to restore files from a different user account, where the need for a backup. If you don't know consider the Apple store again for help, but I guess that this situation is a bit difficult for you.

    See if others here have a better idea too, it is better not to act too quickly in situations like this, unless you have copies of the data on another.

  • How can I change the location of the weather on the empty search page?

    in the upper left corner of the image is a place of the weather (not my current or even good location... I don't see this when I open a new window empty, and even if this isn't a real big problem I'd want to see the where I am or not show at all.)

    I can change it's what my current position? (automatic would be nice)
    If so, how to change that?

    Hi Brian, I don't know how AVG that calculates the information on the page. It may be a feature of an add-on or a website, I can't say. If you click on the location (the color makes me think there is a link) it lets you change there?
