Extremely slow running query.

• Characters not visible (caused by hitting the bar space or TAB in PL/SQL developer tool) causing slow running query? and database with low performance?

  Hi all

  I need your help to get this issue resolved its urgent and I'm not able to get to the conclusion. Here is my scenario, I'm getting slow query runs because of some non-visible characters that are copied with the application of the PL/SQL developer tool. Please find below attached screenshot: Oracle_Issue

  

  Note: This non-visible characters are caused when we write the query then us hit the SPACEBAR or press TAB PL/SQL developer tool

  I use the developer tool PL/SQL to write or test the query. Now I take this request copy paste in my application of the company (who takes this query connects to Oracle or any source of data base, catch data and produce PDF reports for customers).

  Now, my client is the Oracle user when I write and you run this query by the PL/SQL Developer, it works fine, but when I paste in my Inbox feature request (reporting system) and run it, it runs slower and jams to the customer database. Now after a little research I found that when I copy the query directly from PL/SQL developer at my request, he copy some characters not visible (introduced when we press SPACE or TAB in PL/SQL developer tool when writing query) with the request, then I copy this query again to my box of the application Notepad and delete these non-visible characters. Now, after removing the non-visible characters again once I copy backup question in my application and run the query, it works normally. Please find below attached screenshot: Oracle_Issue 2

  

  So I think that the cause of slow performance is due to some INVISIBLE CHARACTERS present in the query.

  My application uses SQL server 2008-2012 at the backend to store data from different sources.

  Character set used: SQL_Latin1_General_CP1_CI_AS

  
  

  To write and test queries: PL/SQL developer tool

  My Client use Oracle 11 g

  Character set used: Normal character: NLS_CHARACTER: AL16UTF16

  National Characeter: NLS_NCHAR_CHARACTER: WE8WIN1521

  I just wanted to know the blocking process to the top of the database and the characters not visible how affecting slow running query of query database.

  Please let me know if I'm missing something or you need more information on this issue.

  Thanks in advance,

  HP

  Simple answer. No.

  Spaces and line breaks do not change the execution plan created. Does not plan to run slower or faster.

• Extremely slow running VM XP in Windows 7 (7 post)

  I'm running a Windows 7 thinkpad with 4 GB of ram and a 2.4 GHz processor. When running an XP VM, I get unusually high processor utilization. I ran the same configuration (a laptop even slower) under WS 6.x with much better results. No idea as to what could happen? I've attached a screenshot of its use within the virtual machine.

  The host is Windows 7 RTM and virtual Windows XP SP3 machine.

  Thank you.

  

  Why you set up a virtual computer with 2 processors - your host should have at least 4 cores before such a framework works well.

  But in this case, I guess that there is also something wrong with the USB - if you do not need USB disable for a test

  I created an index on the trans_date column, and it is originally a range of indexes on the table instead of a table scan full scan.

  I'm not Nikolai, but you're welcome. ;)

  Now turn this trans_date the composite index index, I suggested, for an even better improvement.

• My MacBook Pro is running extremely slow all of a sudden. Help, please!

  My MacBook Pro is in running extremely slow all of a sudden, that way for several days now and I can't understand what is the cause.

  Details: MacBook Pro (13-inch, late 2011)

  Processor - 2.4 GHz Intel Core i5

  Memory - 4 GB 1333 MHz DDR 3

  Storage - 500 GB SATA (264.44 498.88 free GB) drive

  OSX - El Capitan 10.11.5 version

  I tried the simple things such as checking for indexing spotlight, my home screen of the size of the compensation, first aid running in disk utility, etc.. But had no results. Any suggestions would be very appreciated!

  Back up all data immediately, as the internal drive may be failing.

  When you see a beachball cursor or the slowness is particularly bad, note the exact time: hour, minute, second.

  These must be run as administrator. If you have only one user account, you are the administrator.

  ☞ Enter the first letters of his name in a Spotlight search. Select from the results (it should be at the top).

  ☞ In the Finder, select go utilities ▹ of menu bar or press the combination of keys shift-command-U. The application is in the folder that opens.

  ☞ Open LaunchPad and start typing the name.

  SYSTEM LOG QUERIES ▹ all Messages

  in the list of logs on the left. If you don't see this list, select

  List of newspapers seen ▹ display

  Each message in the journal begins with the date and time when it was entered. Highlight date back to the time you noted above.

  Select the messages entered since then until the end of the episode, or until they begin to repeat, whichever comes first.

  Copy messages to the Clipboard by pressing Control-C key combination. Paste into a reply to this message by pressing command + V.

• iTunes running extremely slow

  I'm having a problem with extreme slowness.  I have read all the post and don't see anything that I could change to correct this situation.  I have my music on an external disk file using the FireWire on my iMac.  I have the latest Mac os 10.11.1 and the latest iTunes version 12.3.1.23.

  I lit the apple music, but I'm not using the icloud or search service

  I have 127,88 GB of music on any external drive

  At this point, I am considering canceling music apple and past to another service, and I plan to download an alternative product to iTunes.

  Is it possible that you and Podcasts iTunes can get their own programs as they do on the iPad and iPhone?

  What would be a good alternative to iTunes?

  Thanks for any help.

  One thing you should do is to run disk utility and test the volume of the external drive to confirm that there is no alteration of the data on it.  You can do this by selecting the disk external volume (indented under the Unit) in the disk utility sidebar.  Click on the button of first aid , then run it.  The corruption of data may cause slow access.  Also, if the player is close to being full, which can strongly increase the fragmentation of data, which can cause slow access, especially if the drive has been through cycles to get closer to satiety, followed erase you data in order to free up space, followed by get start near new...

  My iTunes Media , also on an external FireWire drive folder, is currently 315 GB (with things that take more space as films, TV series, video podcasts, etc.).  I actively use two Match iTunes and music from Apple.  I don't feel any slowness.  You can do additional tests on your system to determine the cause.

• When the computer remains in standby mode it will not start normally, usually ok in safe mode, but even when its up and running normally it's extremely slow.

• Dreamweaver cc 2014 running extremely slow

  Dreamweaver CC 2014 is running extremely slow - with essentially no response (using the split or any other mode mode). My version of CC works perfectly - fast and clean. I have not changed anything - I have to install the new 2014 CC and tried and it doesn't fundamentally. What is going on? I have an iMac 2012 - updated my OS a lot of RAM, etc. I have a lot of open fonts, but this has never done other programs - just wondering if perhaps behind the scenes its reading of all this stuff (why would it?).

  Thanks Preran.

  My external drives (nine in total) were originally of course DreamWeaver 2014 to a problem of 'mapping' of readers. However, by connecting the USB drives first, restarting and opening DreamWeaver 2014 once again, it worked as expected. Add two additional discs to high speed and restart again, all mounted drives and checking dreamweaver acted as it should and it behaved as it should.

  That solved my problem.

  Thank you

• VMware Fusion 3 running extremely slow...

  First of all, my MacBook Pro:

  Core 2 T9300 2.5 GHz

  4 GB memory

  250 GB SATA HARD DRIVE

  Snow Leopard 10.6.1

  VMware Fusion 3.0

  When I was with Leopard and VMware Fusion 2.x, the virtual machines run fast, but now they are extremely slow. BTW, I have activated the 64-bit kernel.

  I managed to find the reason, it's because the "mds" in the host OS process, is not a problem of the guest operating system. Everytime I turn on my Windows XP in VMware, "mds" will appear in the activity monitor window, and account for about 2% ~ 20% CPU, hard drive usage becomes noisy at the same time. What I could do is just wait, after about an hour, mds will be 'calm down' and my MBP back alone. But, when the next time I turn on my virtual machine, "mds" will appear again...

  "Mds" makes me crazy... I tried to google for answers, but no result.

  Anyone faced this problem too? Or someone knows how to solve the problem? Thank you!

  We found just a bug where in some cases fusion 3 will be a spotlight on every launch search (it is supposed not only to occur once), which seems to be exactly what describes this thread. You can work around this bug open Terminal.app and running

  defaults write com.vmware.fusion PLLibrarySpotlightSearchDone -bool YES

• Convert an Esxi 4 2 Server VM runs extremely slow

  Hello

  I am very new to virtualization and have just the configuration server ESXi 4 that will replace the VM Server 2 systems we tested.  Recently, I tried to convert one of my server-2 VMs (Using the 'Converter Standalone Client') a VM (Version 7) Infrastructure.  After two days of continuous operation, the converter was only 5% finished and was transferring data to 24 kb/s (the server is ~ 150 GB in size).  This seems to be extremely slow and I hope that there is something that I can do to speed up that this server should run during opening hours and I like that, I can't take it down more than the weekend.

  I ran the converter Client on the server that hosts the virtual machine, and that server and the ESXi have dual network adapters connected to a managed switch of FD 100 MB.  (They are both on the same switch).  The virtual machine was not working and there was almost no other network activity going on during the conversation.

  Any help is appreciated

  The goal is to eliminate the things that it is not. Download your installation as simple as possible. I don't know what your problem is, but it certainly seems like a network problem. A single 100 MB network adapter should work much faster than the speed you receive.

  Other things to eliminate are pass the port problems, configuration issues, cable issues, NIC

  Run something like wireshark as you begin your conversion. See if you notice any problems in the capture.

  Create a new fresh installation of the VM on the ESXi host and check the flow rate etc. You don't want to go to production if you have problems. Monday will not be fun if you do.

• Facebook (entire site) runs extremely slow in Firefox.

  This does not happen with all the other Web sites. It is extremely slow-scrolling, loading of pages, etc., and each time I have a Facebook tab is open, it slows down the whole browser. The browser returns to normal speed once the Facebook tabs are closed. The worst thing is when I type a message or comment on Facebook - specific messages - he's so bad that I have to stop and wait for the characters to catch up to me, sometimes for several minutes just finish one sentence until I can move my real typing speed. It makes it extremely difficult to use as a communication tool and I don't know what to do about this.

  I had this problem (Linux though). Disabling the extension DownloadHelper solved it for me.

• My Mac Mini is extremely slow and any video will start but soon stops and intermittently starts and stop immediately. What is the reason?

• Please help make the equivalent of a defrag on my Mac, as it is extremely slow

  my Mac is extremely slow, painfully slow in reality and needs a cleanup but I don't know how to delete it all waste such as cookies etc and help run faster.

  Help, please

  Cookies do not affect the performance of Mac, and there is no advantage in "defragmentation". Do not use any product that claims to "clean up" your Mac either. They are all scams.

  Back up your Mac if you have not already done so. Read https://www.apple.com/support/backup/to learn how to do this. To learn how to use Time Machine read to use Time Machine to back up or restore your Mac.

  Determine if the problems persist also in 'Safe Mode':

  • "Safe Boot" or Safe Mode is a troubleshooting mode that bypasses all system of third-party extensions and only loads the required system components. Read about it: departure upward in Safe Mode
  • You must turn off FileVault before you start your Mac in Mode without failure.
  • From your Mac in Safe Mode takes longer that usual, graphics won't get smooth, audio is disabled on some Macs and some programs (iTunes for example) may not work at all.
  • Just from your Mac in Safe Mode does not solve the problem, it's to observe its performance without additional components.
  • To end, Safe Mode restart your Mac normally. Stop will take more time as well.

• Extremely slow on my Satellite Z930 - 15 X

  Hello

  Here is my problem (sorry for my English):

  I have a Toshiba Satellite Z930 15 X.

  For several weeks, it is very very slow. If eco or normal mode, it is still slower than the eco mode. * Even without running any program *. When I look at the Task Manager, everything is ok and fluid.

  Is this a hardware problem?
  I also noticed that the fan works far more often than the first months of use, even with just an open word document.

  The only solution I found is to restart the computer.
  After each restart, it is fast as usual, but only for a short period. But at one time or another, the extreme slowness often returns after a break.

  * I also noticed that it often occurs after a suspension or the connection / disconnection of the laptop from the AC outlet.*

  (I said I have a few programs installed and no trace of virus and other software malicious (I'm very careful about that)).

  Have you had this problem, where it comes from, what can I do?

  Thank you!

  Hello

  On this virtual path, it is not easy to tell what exact reason. To be honest I don't think that there is a hardware problem. Fact is that many background processes can slow down the performance of s for laptop. Perhaps some context downloads and installation of the update may be reason your laptop reacts quite slow.

  Please check the commissioning and disable all unnecessary applications. If you do not use some of them, they should not start with Windows and run in the background. Also check Windows update option. Turn off automatic updating.

  If please do first and check if the laptop runs a little faster.
  Please post comments.

• Extremely slow printing wireless with HP Photosmart Premium C309g-m

  I see extremely slow print speeds when printing from a Mac or a Windows XP system on a new printer HP Photosmart Premium C309g-m wireless. The printer starts printing immediately when I request a print, but it only prints one line. It will take about 15 minutes then to print the rest of the page, each print after a very long break line. Print demo page doesn't exhibit this problem, only documents of programs such as Word 2008, Safari, and Firefox (I tried firefox on PC and Mac) are affected.
  
  If I connect to the printer via a USB connection it prints very well, so this problem seems to be the only wireless printing.
  
  Printer: HP Photosmart Premium C309g-m
  Computer: Mac mini (late 2009 model) (also tried a Windows XP laptop, by comparison using the latest drivers from the HP website)
  OS: Mac OS X 10.6.2 with all available updates installed
  Method of connection: cable Ethernet connection to the router wireless
  Printer drivers: version 2.2.1 (Apple provided, drivers HP never installed as system comes with 10.6)
  Wireless router: Apple TimeCapsule (early 2009) 1 TB, honing a/d and modes of b/g on 2.4 and 5 GHz. TimeCapsule is in transition as the DSL modem handles DHCP service mode
  Encryption: WPA2 Personal, no MAC filtering or hide the SSID.

  IP addressing scheme: all addresses are distributed by the server DHCP without reservation of any kind

  The TimeCapsule is sitting three inches from the printer and the printer indicates the complete signal. Connecting the printer to the wireless network and setup of the printer on the Mac went off without a hitch. Only when you print a test document discover us the problem. The wireless network will behave as expected when you access Internet from Mac and Windows devices (tested with a laptop computer Dell XP and a MacBook with OS X 10.6.2), so I don't see any problem with the wireless network together.
  
  Attempt to use:
  1 reboot and power off, wait, restart the computer
  2 reset the print subsystem, the printer off and on again and reinstall the printer

  3. disconnect the power to the printer and let it sit for several minutes before trying to print wireless.
  
  None of them worked.

  I don't know exactly what is happening... I'll have to think about.

  Looks like you're running with the current configuration.

  Can we call this resolved?
