How to find db file scatered read in the trace file?

Hi all

Was just going through the basic concepts...

1 lines of the created table T1with 1000 in LMT block size of 8 k.
2. followed enabled - change the context name of session set Event 10046 trace forever, level 12';
3. done - select * from T1;
"4 ALTER SYSTEM SET EVENTS ' trace 10046 name context off."

Now I have not found any scatered db file read in trace, as select opted for full table scan... What is the problem here?

I have found that sql * net messages in the trace file.

1. Yes, the table name (tt1 vs t1) is strange.

2. in addition, from 10 g, your application would be sampled, dynamically, without collecting statistics. While sampled dynamcially, blocks would be loaded into the cache. Collect statistics, RAS buffer cache, then trace with Event 10046.

    During the installation of xp does not load the wmp.dll file - does it affect my screen resolution which is now fixed to the
    most low and can not be reset - and how can I fix this?

    =======================================
    No guarantee... but for the wmp.dll issue, the following
    the article may be worth a visit:

    WMP. DLL
    http://www.updatexp.com/wmpdll.html

    For the problem of resolution of screen... There is a possibility
    that you need to update your video driver.

    (FWIW... it's always a good idea to create a system)
    Restore point before installing software or updates)

    Proceed at your own risk *.

    Try searching the website of your video
    MFG. the adapter for a compatible update Win XP
    video driver. Or... If your computer is a laptop...
    Search the support site for your computer
    Reference of the manufacturer.

    If you do not know the make and model of your
    Video adapter, see the documentation that
    supplied with the computer.

    Also you can find info on your video by driver
    go to Device Manager: you can launch
    By clicking Device Manager on... Start/run and
    type or copy / paste:
    devmgmt.msc
    And then press ENTER.

    Expand "Graphics cards" and right click
    the name of your graphics... then
    choose... Properties / tab pilot... FYI.

    You should find the make and model of your
    adapter display as well as the version of the driver.

    If the driver on the Web site is no longer
    current than you run...
    Download and install it. In addition, installation
    instructions that should be followed closely
    should be available on the support site.

    Good luck.

    Thanks, Newbie Mel

    Hello

    The Prefetch files should not be deleted. This will slow down the normal operations.

    When you use the computer, the prefetch files are created for the programs that you use normally the most. This allows these programs to load faster.

    If you delete the files prefetch, the system must then start over again and recreate the files that you are using the computer.

    The Prefetch files are located in the C:\Windows\Prefetch folder. They are data files and are not human readable.

    I have a dell computer used (vista), while mine is in the shop, the date system and time is not set. How to find the password of Setup/system to set the time and date. I set the time and date using the Panel control, but within a few hours, it changes again in May 3,2003 Help. Thank you

    [Moved from comments]

    If you have changed the time and date in the Panel, and he continues to return to an older date, then this is probably the CMOS battery that has gone dead. If it is a loan, I wouldn't worry on this subject. If it's your own old PC, then you can change it. Is this a laptop or desktop PC? What brand and model is it?

  • How to find and replace a URL in the content

    See the following page:

    http://democraticpartyofgeorgia.org/events/index.cfm?fuseaction=week & SM = 9 & SD = 9 & SY = 2007

    He pushes the margins way because some people type in long URLS in their description of the event (see the meeting September 10). I would like to be able to analyze the event description and replace that long url with a hyperlink where the long url is in the attribute href, but which is related is something link 'see link'. Is it possible to do? I can search for the instance of "" http:// ' of course, but can't seem to find a way to tell where the ends of the link... "

    Look at the ActivateURL udf to
    http://www.cflib.org/UDF.cfm/activateurl

    It's really more a question on a very long word of packaging. The URL is not packing, and it's what drives your margin. You need the column to encapsulate your column is a bit more liquid.

    Use the wrap() function CF.

    You can also go the road CSS, but the best solution I found only works on IE.

  • How to find a file on a new nano

    I downloaded several audio books from my local library using OVERDRIVE and then transfer them to an IPOD touch.

    Tried with a new Nano, the transfer seemed normal.  But I could not find on the Nano.  Using Windows, with the attached Nano 10, I could see the correct mp3

    files.  But I can't see them anywhere on the Nano.   I then downloaded music from I Tunes store and that transferred very well and was there, where it should be.

    I looked in every folder under the music tab and that you still can't find my audio book.

    Is there a way to search?

    Thank you in advance,

    Loren

    How you did transfer the audio files to iPod nano?  If you can see them using the Windows 10 file manager, do you have transferred their dragging files to the iPod using Windows?  If so, you must use iTunes to synchronize audio books from the iTunes library to iPod.  This is how the content is loaded onto the iPod, use iTunes.  iTunes data are hidden on the iPod and stored in a special way that allows access by the software shipped from the iPod. When using the Windows File Manager, you should not see the audio books to MP3 files at all.
