• Execution of SQL query for slow down

  Hey all!
  
  I use 10g express with apex 3.1 edition, when I run this query:
  
  Select asig.idasig IDASIG, asig.idAsig 'C & oacute; Digo Asignatura", ID asig.idasig, substr (asig.codigoasig |) » '|| ASiG.nombre, 0, 40) "Asignatura", p.nombre | " '|| 'Responsible' p.apellidos, t.usuario 'T & eacute; Técnico", substr (ea.estado, 0, 22)"Estado not', ec.estado "Certificado de Estado", cert.idestado
  certificado cert, asignatura asig, histasig ha, profesor Técnico t, p, estado, estado ea
  where cert.idasig = asig.idasig and
  p.idprof = asig.idprof and
  t.idtecnico = asig.idtecnico and
  * cert.idasig (cert.fecha) in (select idasig, max (date) of the Group idasig certificado) and *.
  EC.idestado = cert.idestado and
  HA.idasig = asig.idasig and
  * ha.idasig (ha.fecha) in (select idasig, max (date) of the histasig of idasig group) and *.
  EA.idestado = ha.idestado
  
  It is too slow, making the query gets results in approximately 149 s.
  
  Can someone give me an idea...
  
  PD: the case is that we have another query that do almost the same thing but with this one, I get the results in less than 1 s.

  Just posting your query without any other information is meaningless for us.

• Firefox slows down for several minutes, as if (possibly), it seems "reoganise".

  Hello!

  Every once in a while, Firefox slows down a lot, the use of the CPU (for Firefox) exceeds to 95pct and there is a lot of drive actuvuty. Then after a minute or so, it starts again to normal.

  What does Firefox do? Is this normal/expected behavior? 'Help' Firefox if it needs to have something cleaned?

  I use Archlinux.

  Thank you

  Thor

  Some quick ideas (in the order that I would try them):

  • Clear your cache. It is possible that some of your cache files are corrupt and Firefox chokes on them.
  • Try to disable the Flash plugin. My experience with Flash on Linux has been less than stellar, and I would not be surprised if it causes problems. If it turns out that the Flash is the issue, you should try grabbing the newest alpha/beta 10.2 and see if that fixes it.
  • Try to open Firefox in safe mode. Which will disable your extensions and many custom settings.
  • Try to start a new profile (be sure to keep the old). There could be something wrong with your current profile (which contains all user-specific data).

  It will obviously be a pain to test if it happens only once a day or two, but that's all I can think about. Best of luck, it attaches, and with a little luck, someone else will have a more specific patch.

• Windows Indexing running for hours each day, slowing down computer

  Every morning when I start my laptop, the Windows Indexing service starts.  He turns for hours and really slows down my computer while it is running.  I suspect that it is a new construction index every day and not incremental update.

  Last week, I opened administrative services, found indexing service and set its startup type to disabled.  When I go in there now, he said that the service is stopped, but in my status bar windows taskbar system, it is still ongoing.

  I am running Windows XP Professional Svc Pack 3.

  Help, please!

  You probably mean the Windows Desktop Search?  (Which is not the same as Indexing Service).  Go to add/remove programs then uninstall it.

• Is it better to slow down the DVD recorder for best results?

  I read somewhere that it is better to slow down your burner DVD 16 x, 2 x or 3 x for best results.

  Isn't anyone agree with this?

  I burned several disks now and had trouble with them. (using less expensive DVD-R discs)

  I also heard that I should use DVD + R.

  Dano

  I use high quality DVD + R media and burn at a speed included between 2 and 4 X. Didn't have a bad burn in the last 4 years.

  Also in the past a marginal DVD burner (was running out) was also a headache for a short period of time.

• Video slows down after playing for awhile on my HP 15 - D041TU (no problem heat as well)

  I bought this new laptop from the store, it came with freedos and I installed windows 7 64 bit and service pack two institutions then I installed VLC Player, player of SM & Daum Pot player just to use on my video observation on the day the day.  Well, everything works perfectly fine except that when I play the video for a while, it started to slow down, it works fine otherwise. It starts somewhere around 30 minutes and beyond. I tried with all the players, and this happens with BlueRay rips I which is HD video. Whats happening people? is this not enough powerful computer to play an HD movie? If she then I'm really in big trouble, because the main reason for me to buy it was to watch movies and surf the Internet. If I'm not one of them on this it's really bad for me . What causes this? Anyone have this problem? I watch movies connected to ca all the time and balance power profile. I also look in the standard settings of the player. The machine has 2 GB of Ram and processor Celeron 2810 n. Is this a problem with windows 7?

  DerekQ, being a PhD studen I respect that, but I don't understand all the interest you're going. I know he has windows 7 drivers, and to be honest some of them actually does not work with the system. I already found a solution, and I also found a solution to my problem of video playback.

  Solution to the problem is VSYNC disable in the player and the video plays perfectly fine.

  Yes, of course, it's my problem, otherwise why would HP nag about it?. So the solution is itself the problem and I hope that this thread helps people who are getting the same problem in the future.

• After you install the update for Vista (KB250189} why would slow down)

  After this connection to Explorer 9 update and other web sites really slows down. If uninstalling it goes back to normal but reinstalls on automatic update. Anyone else seen the same thing?

  Hello

  I would suggest hide you the update.

  Here's how:

  a. open the control panel (all items view), and then click Windows Update
  (b) after the updates of Windows, or if you are looking for updates, click on the update (s) available link.
  c. right-click on a Windows Update listed that you want to hide, and then click Hide update.
  Note: If prompted by UAC, then click on Yes or enter the administrator password.
  d. you will notice that the now hidden Windows Update is grayed out.

• Pavilion dv2000 laptop computer under Win 7, slows down or freezes for a short period.

  My Pavilion dv2000 running Win 7, slows down or freezes for a short period of time where, what seems to be, a talk-show audio plays.  Someone knows how to turn off tv and audio if you use no background.

  I solved the problellm. After stripping the system of all the games and all other third party software, I discovered that the problem would occur when connected my net. If I started and did not attach the net audio problem has not occure.  It turns out that one of the files system temp to explore has been altered by a virus which, down, loaded each time that the system connected to the net.  Problem showed when testing the hard drive.  Ran the disk check which fixed the corrupt files, then reinstalled win 7 and other necessary software.  All right.

• about to buy a video.  It contains options for speed on the overview of the site, do get the same options to slow down the video down when I buy the video?

  about to buy a video.  It contains options for speed on the overview of the site, do get the same options to slow down the video down when I buy the video?

  The videos is not 'options '. They are exactly as described. You can use first to add slowed to any video. Correction of the one who is already slowed to normal speed may not produce get results.

  But to answer the question, the videos are exactly as in preview. It would be to you on how you change them and with which application.

• All Citrix PS4.5 slows down for 15 minutes

  All my Win 2003 Citrix PS 4.5 VM slows down for 15 minutes, let's say about 9 AM PST everyday and resumes its normal operation thereafter. No regular job, don't backup, AV running at those hours. No related events in the Windows Event Viewer. Representation monitored for a week CPU, memory, and disk IO are normal, so suspecting problem at the level of VMware.

  All Citrix VM are in a warehouse in SAN.

  ESXi4

  No performance problem ESX (below 60% of use of memory and CPU)

  These Citirx VM are servers Dell 2950 P2V conversion.

  Pointers/suggestions/solutions to this problem is highly appreciated.

  Thank you

  KrisK

  Sorry for the delay in response, I noticed that you use for your P2Vd 7 material machinery, test a defined but P2V hardware level to Version 4.  I saw some problems with the Citrix HW7 customers

• Slow down audio files of the word. Best Audio Editor for...

  I need to slow down the files of Word (audio books) around 80% of the original speed. Hearing will do the job without losing height, or it can it compensate for?

  Thanks for the help

  Yes.

  Effects/time and Pitch/Stretch it will do for you.  Make sure you that the "Time stretch - canned pitch" option is selected, this is the value by default so that it will probably be.

  If you try to make too big a change of speed or the tar, it starts its artificial but you can work what is acceptable by trying.

• "the db file sequential read" waiting for event slow down an application.

  "the db file sequential read" waiting for event slow down an application.
  
  It is a rather strange problem. There is an update statement that hangs on the wait event 'db file sequential read' and until you restart the database, the query works fine. It happens once a week, usually Monday or after several days of large amount of work.
  
  I checked the processor and is fine, memory is very good, although the SGA and PGA have taken maximum memory. Flow of the disc seems to be ok since each another session on the basis of data looks very good.
  
  I guess that there is a missing configuration to avoid having to restart the database each week.
  
  Any help is greatly appreciated.

  and for small tables, you can try adding for example FULL (your) FULL (wsr)

  It can be rewritten in a different way, but it's the fastest way to try how query will be if you rewrite it. Check the explain plan command if certain partially ordered tables are not joined because you can get the Cartesian join, it seems that it will be ok.

  View query result in the em console.
