Query takes a long time

• Select the query takes a long time to run the second time

  Hi all
  
  I have Oracle 11 GR 1 material in windows server 2008 R2.
  I have a few tables with 10 million documents. When I run the select query to the tables of first time, it gives me a result in 15 seconds, but if I run the script even twice in the same session, I get the result in 15 minutes to complete...
  
  Why it's happening? What can be the solution for this?
  
  Thank you and best regards,

  What I know is that this feedback from cardinality generates more problems than improving the performance is, in fact, its main objective. But first look at which is was written in the link I posted above

  "Return of cardinality was introduced in the Oracle 11 g database 2. The purpose of this function is to automatically improve plans for queries that are executed repeatedly, _For that the optimizer does not estimate the cardinalities in the properly_ plan"

  If the cardinality feedback kiks in your case it is certainly because you do not have an exact statistics. Get the command the explain plans that I have shown you with the E-lines and A-lines (lines estimates and actual lines) and see where things are poorly estimated.

  If you want to disable the cardinality feedback then add the indicator according to your request

  /*+ opt_param('_optimizer_use_feedback','false') */

  Never perform a treatment by data line. SET the computer base. Direct use of the joints and cut single SQL. Your condition can be obtained by using the merge statement.

  merge into customer_alignment c
  using (
          select vw.affiliation_id
               , ca.customer_alignment_id
            from customer_alignment c

              on t.tenent_id       = c.tenent_id
             and t.tenent_id       != 0
             and c.affiliation_id is null
            join customer_alignment ca

• Firefox takes a long time to close since a recent update and memory of pigs.

  Since the recent updates that have begun to use containers of plugin, Firefox takes a long time to close. If I try to go back there, he said that it is still running. I have liik in the Manager of tasks and about seven containers plugin. exe is running, and I turned off or disabled mostplugins and addons, same Quicktime. Firefox uses an obscene amount of RAM on my XP machine and rendered sluggish. I use XP SP3. This started after you added the plugin container in one of the recent updates earlier in the year. For the features it offers me or does not offer me, instead, it uses far too much RAM and is too slow. And takes a long time to close when I close the browser. It uses about twice as much RAM as it was.

  Upgrade your Firefox 9 browser and check

• Pages take a long time to load in versions 6,7 and 8, version 5 works fine.

  Version 5 works fine, when I updated to 6.7, and now 8, pages take a long time to load. It's on 2 different computers, one with Vista, Windows 7 other. If I restart Firefox it helps, but the problem comes back. Does not happen with IE or Opera.

  The default value of the pref Network.http.Max - connections has been increased from 30 up to 256 in versions of Firefox 6 +.

  Try to decrease the value of the pref Network.http.Max - connections 256-30 such as used in versions of Firefox 3.

  • https://support.Mozilla.com/kb/Firefox+never+finishes+loading+certain+websites

  One possible cause is security software (firewall) that blocks or limits Firefox or plugin-container process without informing you, possibly after the detection of changes (update) for the Firefox program.

  Delete all rules for Firefox in the list of permissions in the firewall and leave your firewall again ask permission to get full unlimited access to the internet for Firefox and the plugin-container and the update process.

• The system preference takes a long time to load

  As the title suggests, end of 2013 (10.11.4) System Preferences on my iMac takes a long time to load, even after a fresh reinstall and/or reboot (tried both). It takes about 20 seconds to one minute each time to open (except when I close it and immediately open it once again, as it is always loaded in memory). This problem existed only after the upgrade to El Capitan, and I saw many other people with iMacs with the same problem. I tried to remove cache for before system preferences files, but that did not help at all. I don't have a FileVault if it makes a difference, even if I did before reinstall, but never turned back (persistent question anyway). Any recommendations would be useful. Thank you!

  Data sheet:

  iMac (end 2013)

  Intel Core i5 at 2.7 GHz

  8 GB 1600 MHz DDR3

  1 TB 5400 RPM HARD DRIVE

  Intel Pro Iris 1536 MB

  I found it is the State of affairs in 10.11 if running a HD spinning.  Don't feel alone.

  I suspect that it is a function of low priority in the memory compressed algorithm.

  Upgrading to an SSD and it will rise to attention.

• Satellite M300 PSMDCA takes a long time to start

  I have a Toshiba Satellite M300 PSMDCA - 01800C and there are some problems with it.

  First of all, when you start the computer, it takes a long time to start and activate Outlook.
  I am running Windows 7Home Premium.
  Computers arrow where I bought the computer told me that it can take up to three hours to go back through each process at startup?

  Is it normal that all I wanted was a simple portable easy fast, but it seems that I am stuck again.

  Also, when I go back to the computer, even after some time the mouse it does not provide new and pushing the Start button just a blank screen. Alt + Ctrl + delete, then he activates Windows again and then after having put my password and I have to wait for that be again loaded everything that takes so long. Any ideas?

  Also I often get the message when the computer starts "error has occurred in Toshiba PC Health Monitor. He will leave the application. "Main.frm.cpp (184). Any ideas?

  Quite often when I am scrolling with the mouse, the screen will turn black and flash and a message «the NVIDIA display driver... couldn't Reg...» "and he will correct itself after awhile. Frustrating!
  Quite often when scrolling on the websites of the page I'm going to freeze?

  I use MS Office 2010 and there is a problem trying to save Word documents and a message comes up with "a file permission error.

  Any thoughts? Thanks, Shirl51

  > First of all, when you start the computer, it takes a long time to start and activate Outlook. I am running Windows 7Home Premium. Computers arrow where I bought the computer told me that it can take up to three hours to go back through each process at startup?

  This nonsense!
  The system should boot up quickly my laptop needs 30 seconds to start.
  In my opinion, the system is screwed

  In your case, I recommend to reinstall the system.
  Did you create the recovery disk?
  If this isn't the case, I think that detailed instructions should be placed in the user's manual.

  After the recovery of disk has been created, restore the system, BUT save the data before doing so because the recovery disk would be to format the HARD drive and you lose data!

• Visual Studio 2008 Pro takes a long time to start after the installation of measurement Studio 2009

  After installing Measurement Studio 2009, I noticed that it takes a long time (30-60 seconds) to open a Visual Studio project.

  I do not have an internet connection on my development computer and suspect he might be waiting on some kind of operation of the network to time out.  I had problems with Visual Studio in the past as well and had to work around them by adding entries to my hosts file (to redirect some addresses of Microsoft to the local IP address - this causes network operations to expire immediately).

  Just curious if anyone has encountered this kind of slow startup time and found a solution.

  Thank you!

  I found an article referring to a question similar to MS 8.1.  I don't know if the problem has simply not been corrected or why I am still having this problem.  Workaround "per computer" listed in the article solved my problem.

• XY graph sometimes takes a long time to update legend

  Hello

  I wrote a small piece of code that highlights (changes line width) the plot on the graph when we click a mouse on its name in the legend of the plot. The code works well except when I the legend scroll bar is visible and its position is not 0, then when I click on the name of the parcel, the chart takes a long time(>4s) to change the width of the plot on the legend. The plot on the graph is updated instantly. Its only the legend of the plot that takes a long time to get updated.

  I enclose the code here... Please, run it and see if you also see the same behavior.

• videos take a long time to buffer

  Hello

  1. what operating system is installed on the computer?

  2. what version of web browser work?

  3. do the same thing happens with all the videos that you try to play?

  4. I think you are referring to the videos online?

  5. How do you try to play the video?

  If you use Internet Explorer and facing problems, watch videos online, then you can check out the link below:

  The video problems when you use Internet Explorer

  http://support.Microsoft.com/kb/2532294

  Note:

  There is no option within the operating system to increase the speed of buffering. Only way to increase the speed of buffering in some measure is to have a connection with a higher bandwidth. But note that as does you not an option of continuous play in CD or DVD.

  Another work around that I do personally is to pause the video to complete the buffering and watch the video once the buffering completed.

  I hope this helps!

• desktop computer takes a long time to load after uninstall of netware

  Dear Pascal, recently, by chance, I installed the client service for Netware on my PC. He asked to restart the computer, and after reboot, logon screens became classic. I uninstalled netware by accessing the properties of LAN. I managed to restore logon screens using Microsoft resources available on the net. However, my PC now takes * for long time for the desktop icons and toolbar are displayed. I use Microsoft Windows XP Version 2002 SP3, Intel Core2Duo processor P8600 @2.40 Ghz with 2 GB of RAM on Lenovo Thinkpad R400. I understand that it is after uninstalling the netware client that my office is very very slow. Help me for a faster loading of the desktop computer. Best regards, Reba Shankar

  Hey Reba,

  Thanks for choosing Microsoft Community!

  You have reached the right forum. Try to solve this problem.

  If I understand correctly, you have some performance issues on windows XP computer.

   

  Let us try the following steps:

   

  Method 1: Any installed program must be uninstalled from Add and remove programs. You can just remove shortcuts from other places like LAN properties.

  Run the following fix - it to uninstall client services for Netware.

  Important notes:

  ·         Running chkdsk on the drive if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data can be lost.

  ·         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.
