  You think you're going to lines updates 85K, Oracle think it will update a line.

  At the time where the existence of the first test runs that oracle think already up to 49 lines, which is probably why he uses the loop join nested for the second test. (In your version of Oracle, the subquery introduced existence a very bad assumption (small) on the amount of data will survive).

  It is possible that you will get better performance if you hint Oracle using a hash join for testing the existence - and you might want to think what test will eliminate most of the data and that we can first force.

  Having said that, however, note that MMR_DTL research is a considerable fraction of the cost of the query - and an analysis is an easy thing for Oracle cost properly - if, despite your comments on update a column with a clue to this topic, you will find that the query can be more effective if you use an index. This is more likely to be the case if data ' WHERE CAPITN_PRCS_IND = 5 AND HSPC_IND = 'Y' "is well grouped (perhaps the latest data added to the table).". "  You could then reduce the cost of maintaining this index by creating an index based on a feature that indexes only the lines where the predicate are both true so that the 2 update deletes the index entries and allows the index remain as thin as possible.

  Hello

  I have a table that contains data for the last 5 min, maximum (500 lines), this table is in NOLOGGING mode.

  I have another process that get these data every 5 minutes and then remove each row in this table.

  As my table is in NOLOGGING mode I was questioning myself if this better to TRUNCATE the table or DELETE all ranks.

  I did a trace to see the result, but I'm not sure of the conclusion:

  @rp0428 I have no control over this, if you have a suggestion, I'm very open minded

  , Thanks for the STORAGEclause of RE-USE, I'll have a look.

  The button Delete and truncate made with about 130 lines each, at the exit, it seems that the truncation is longer but consumes less resources.

  Ask yourself that question 'control transaction' is a more important than potential problem on.

  I followed the basic rule is: if it ain't broke, don't fix it.

  You have not posted ANY reason to believe that you still have a problem.

  Until you really have a problem to choose a solution and move.

  As it has already menntioned AND TRONQUER LOADING/RELOADING operations

  1. is evolutionary movement

  2 are performing travel as the amount of data increases

  3. use fewer resources (undo, redo, memory) as the amount of data increases

  The above is particularly true for the use case that can benefit from the RE-USE of STORAGE clause such as batch jobs which tend to use about the same amount of tablespace.

  Hello

  Thise drop what you are talking is a set of newspapers and ESXHost configuration files (e.g. unpacking, / var/log/vmkernel etc..) All files have been added to archive tgz. You can extract (sweet 7zip) Windows or Linux (gzip and tar command line tools) I have now if it a tools that will help you analyze these files.

  The only way I know to start the tuning system is fist check performace statistics by each ESXHost (CPU, RAM, i/o per each LUN) for example. for the last days of servén. check when you have peaks on graphs, then go in newspapers of that period of time and start analysing what is.

  BTW. You have problems with your servers?

• Improve the performance of processing image javaFx

  Hello

  I'm working on Image processing with javaFx. I think my code isn't effective favorite (with pictures HD, refresh is very slow). Because I am doing a 'for' on each pixel of my image every time I have to refresh it. But I don't know how else to do.

  So I need help to improve the performance of my treatment.

  This is my code:

  import javafx.application.Application;
  import jvafx.beans.InvalidationListener;
  import javafx.beans.Observable;
  import javafx.beans.property.DoubleProperty;
  import javafx.scene.Scene;
  import javafx.scene.control.ScrollPane;
  import javafx.scene.control.Slider;
  import javafx.scene.image.Image;
  import javafx.scene.image.ImageView;

  import javafx.scene.layout.AnchorPane;
  import javafx.scene.paint.Color;
  import javafx.stage.Stage;
      
  public class Example extends Application {
  
      private Image src;
      private WritableImage dest;
      private int width;
      private int height;
       int value = 0;
  
      @Override
      public void start(Stage stage) {
          AnchorPane root = new AnchorPane();
          initImage(root);
          Scene scene = new Scene(root);
          stage.setTitle("Demo processing");
          stage.setResizable(false);
          stage.setScene(scene);
          stage.show();
      }
  
      private void initImage(AnchorPane root) {
          src = new Image(
                  "http://mikecann.co.uk/wp-content/uploads/2009/12/ScreenHunter_02-Dec.-10-19.41-1024x484.jpg");
          width = (int) src.getWidth();
          height = (int) src.getHeight();
          root.setPrefSize(800, 800 + 50);
          ScrollPane scrollPane = new ScrollPane();
          scrollPane.setPrefHeight(600);
          scrollPane.setPrefWidth(1000);
          dest = new WritableImage(width, height);
          ImageView destView = new ImageView(dest);
  
          scrollPane.setContent(destView);
  
          root.getChildren().add(scrollPane);
          AnchorPane.setTopAnchor(scrollPane, 0.0);
  
          Slider slider = new Slider(0, 255, 1);
          slider.setPrefSize(800, 50);
          slider.setShowTickLabels(true);
          slider.setShowTickMarks(true);
          slider.setSnapToTicks(true);
          slider.setMajorTickUnit(1.0);
          slider.setMinorTickCount(0);
          slider.setLayoutY(700);
          slider.valueProperty().addListener(new InvalidationListener() {
              @Override
              public void invalidated(Observable o) {
                  value = (int) ((DoubleProperty) o).get();
                  color();
              }
          });
          root.getChildren().add(slider);
          color();
      }
  
      private void color() {
          PixelReader reader = src.getPixelReader();
          PixelWriter writer = dest.getPixelWriter();
          for (int x = 0; x < width; x++) {
              for (int y = 0; y < height; y++) {
                  Color color = reader.getColor(x, y);
                  double red = (double) value * x * y / (width * height) / 255;
                  double green = color.getGreen();
                  double blue = (double) value * ((width * height) - x * y)
                          / (width * height) / 255;
                      writer.setColor(x, y, Color.color(red, green, blue));
                  }
              }
          }
  
          public static void main(String[] args) {
              launch(args);
          }
      }
  

  And that's with full HD picture:

              src = new Image(
                  "http://www.freedomwallpaper.com//nature-wallpaper-hd/hd_sunshine_hd.jpg");
  

  As you change each pixel independently, there really is no other way than to use a loop through the pixels. Working directly with the pixel data, rather than use setColor and getColor (...) (...) seems to give some performance enhancements. And there are some general performance enhancements, you can use (reorder the loops, calculate the value used repeatedly, etc.). The performance of this version seems acceptable on my system:

• Help improve the performance of a procedure.

  Hello everyone,
  
  First of all to introduce myself. My name is Ivan and I recently started to learn the SQL and PL/SQL. Then don't go hard on me. :)
  
  Now let's move on to the problem. What we have here is a table (a large, but we will need only a few fields) with some information about the calls. 'S called it table1. There is also another, absolutely the same structure, which is empty and we must transfer the recordings of the first.
  The calls short (less than 30 minutes) have segmentID = "C1".
  Longer calls (over 30 minutes) are saved as multiple records (1 for every 30 minutes). The first record (the first 30 minutes of the call) a segmentID = "C21". It's the first time we have only one of them for each different call. Then we have the next parts (the middle one) of the appeal, having segmentID = "C22". We have more than 1 middle part and once again the maximum minutes in every 30 minutes. Then we have the last part (new max 30 minutes) with segmentID = "C23. As with the first, we can have that last part.
  So far so good. Now we need to insert these call records in the second table. The C1 are easy - a record = one call. But those partial we must combine so that they become a single whole call. This means that we must be one of the first pieces (C21), find if there is a middle part (C22) with the same caller/called numbers and with the difference in 30 minutes time, then additional research if there is an another C22 and so on. And finally, we search for the last part of the call (C23). As part of this research we sum the length of each part, so we can have the duration of the call at the end. Then, we are ready to be inserted into the new table as a single record, just with the new duration.
  But here's the problem with my code... The table a LOT of files and this solution, despite the fact that it works (at least in tests I've done so far), it is REALLY slow.
  As I said I am new to PL/SQL and I know that this solution is really newbish, but I can't find another way to do this.
  
  So I decided to come here and ask for some advice on how to improve the performance of this.
  
  I think you're getting confused already, so I'll just put some comments in the code.
  
  I know this isn't a procedure as at present, but it will be once I have create better code. I don't think it's important for now.

  DECLARE
  
  CURSOR cur_c21 IS
      select * from table1
      where segmentID = 'C21'
      order by start_date_of_call;     // in start_date_of_call is located the beginning of a specific part of the call. It's date format.
      
  CURSOR cur_c22 IS
      select * from table1
      where segmentID = 'C22'
      order by start_date_of_call;
      
  CURSOR cur_c22_2 IS
      select * from table1
      where segmentID = 'C22'
      order by start_date_of_call;   
      
  cursor cur_c23 is
      select * from table1
      where segmentID = 'C23'
      order by start_date_of_call;
  
  v_temp_rec_c22 cur_c22%ROWTYPE;
  v_dur table1.duration%TYPE;           // using this for storage of the duration of the call. It's number.
  
  BEGIN
  
  insert into table2

  Hi and welcome to the forums.

  Thanks for posting your code (and using code tags... it's a miracle of a novice!).

  What would be nice would be if you could provide some example data and expected results; as described in the FAQ: {message identifier: = 9360002}

  Your code is very likely to be slow because of the number of nested loops cursor that you use. Which is known in the trade as treatment of rank by rank (more affectionately known as slow-by-slow transformation, as he was known to be slow). It is slow because the PL engine must keep going back and forth between himself and the SQL engine and the INSERT you in a loop called SQL much time to insert data.

  Usually this kind of thing can be achieved by using something like a single INSERT... ... SELECT statement where the SELECT all the treatment that you put in the language PL, or sometimes a SQL MERGE statement if a conditional is sort of insert/update.

  If you post your data so people can get an idea of what is the logic (and have something to test with and know what results should be) then we can help.

• Improve the performance of web form of Hyperion Planning

  Hi all
  
  I don't know if anyone has tried the method recommended Oracle to compress the forms used in Hyperion Planning to improve the network performance?
  
  http://download.Oracle.com/docs/CD/E12032_01/doc/EPM.921/html_hp_admin/frameset.htm?/docs/CD/E12032_01/doc/EPM.921/html_hp_admin/hpamin-19-17.htm
  
  Slow performance when opening data forms using a Dial-Up connection
  
  Scenario:
  
  Opening a form of data using a slow network connection (for example, with a modem) takes a long time.
  
  Solution:
  
  You can greatly increase the bandwidth network at the opening of the data forms by modifying the web.xml file, as described in this section. This option compresses about 90% of the data stream sent from the planning to the client server.
  
  
  Note: If you are using a WebLogic application server (versions all supported) Web, fill the second procedure, which is specific to WebLogic. If you use another Web application server, follow the first, which contains general instructions.
  
  
  To modify the web.xml file to improve performance, for any application except WebLogic Web server:
  
  1 with a text editor, open the web.xml file located in HyperionPlanning.ear or HyperionPlanning.war.
  
  2 after the tag < / description > and before the < earphone > tag, insert the following lines:
  
  
  < filter >
  < filter-name > HspCompressionFilter < / filter name > < filter -.
  Category > com.hyperion.planning.HspCompressionFilter < / class filter >
  < init-param >
  compressionThreshold < param-name > < / param-name >
  < param-value > 2048 < / param-value >
  < / init-param >
  < init-param >
  Debug < param-name > < / param-name > < param-value > 1 < / param-value >
  < / init-param >
  < / filter >
  < filter mapping >
  < filter-name > HspCompressionFilter < / filter-name >
  EnterData.jsp < url-pattern > < / url-pattern >
  < / filter-mapping >
  
  3. save the web.xml file.
  
  
  If you use WebLogic, you must manually change the .ear file and redeploy to the Web application server.
  
  
  To improve performance with a WebLogic application server:
  
  1. unzip the file HyperionPlanning.ear to C\:ear, for example.
  
  2 unzip Hyperion.war under C:\war C:\ear.
  
  3 with a text editor, open the C:war\WEB-INF\web.xml file and change using the instructions in step 2 in the previous procedure.
  
  4 compress the contents of C:\war to C:\ear\HyperionPlanning.war.
  
  5. compress the content in C:\ear in C:ear\HyperionPlanning.ear
  
  6. deploy the new HyperionPlanning.ear for the WebLogic Web application server.

  Hello
  Yes we did it with a bank that had branches connected to a server through a dial-up line. They are complaining about the amount of data transferred between the branches and the servers. This has worked well on it and has greatly increased the performance of data transfer. However, nowadays the performance bottlenecks are usually not due to the amount of data transferred on the network, but the javascript components that need to run on the client and heavy computing/data and the report creation process.

  See you soon,.

• How to improve the performance of the Intel X 3100 on Satellite L300

  Hello everyone.

  First of all, I don't know if this is an appropriate place to post this thread here or no, but I would like to share with you the experience relating to the improvement of Intel X 3100 (GMA965).

  As we know, there is no driver is good for this chipset from Intel for the moment, especially on VIsta.
  This improvement is made by editing the registry of Intel driver.

  * Steps: *.
  * 1 * open run (Windows + R)
  * 2 * enter Regedit
  * 3 * open the subfolder: * HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ *.
  * 4 * from there you'll see lots of subfolders in video, open each one until you see the folder * 0000 * with + _3DMark03.exe +.
  (For example, my is {HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contr ol\Video\ {B5990899-FBCB-45E1-B0B0 *} and reg DWord _3Dmark03.exe lies in two subfolders * 0000 * and * 0001 *})
  * 5 * in * 0000 * and * 0001 *, create two new * DWORD format: * _software.exe* and * ~ software.exe*, value = 1 (hexadecimal). Here, * software * represents the name of the program you want to accelerate as * _photoshop.exe* and * ~photoshop.exe*
  * 6 * in these files, search for * GFX_Options * and change its value to * 1 *.
  * 7 * restart your computer to activate GFX
  * 8 * repeat step 4 to add more programs you want

  Other updates for the drivers are under developed. However, this method will help you to speed up your computer performance with + heavy + graphical software required. I got double FPS on some software on my Toshiba L300 using this method such as Corel, WarcraftIII and Titan Quest (24-32 fps measurement by Fraps)

  Hope it's useful for everyone.
  Best wishes

• How can I improve the performance of my compaq presario V2000, its very slow

  How can I improve the performance of my compaq presario V2000, its very slow!

  According to many things (specifications, you have now installed vs the programs he came originally with programs, etc.)-it may or may not work better that ever he does now.  However, in terms of nothing other than the software and others on the subject - there are some things you can do to optimize performance.

  Search for malware:

  Download, install, execute, update and perform analyses complete system with the two following applications:

  • MalwareBytes (FREE)
  • SuperAntiSpyware (FREE)

  Remove anything they find.  Reboot when necessary.  (You can uninstall one or both when finished.)

  Search online with eSet Online Scanner.

  The less you have to run all the time, most things you want to run will perform:

  Use Autoruns to understand this all starts when your computer's / when you log in.  Look for whatever it is you do not know using Google (or ask here.)  You can hopefully figure out if there are things from when your computer does (or connect) you don't not need and then configure them (through their own built-in mechanisms is the preferred method) so they do not - start using your resources without reason.

  You can download and use Process Explorer to see exactly what is taking your time processor/CPU and memory.  This can help you to identify applications that you might want to consider alternatives for and get rid of all together.

  Do some cleaning and dusting off this hard drive:

  You can free up disk space (will also help get rid of the things that you do not use) through the following steps:

  Windows XP should take between 4.5 and 9 GB * with * an Office suite, editing Photo software, alternative Internet browser (s), various Internet plugins and a host of other things installed.

  If you are comfortable with the stability of your system, you can delete the uninstall of patches which has installed Windows XP...

  You can disable hibernation if it is enabled and you do not...

  When you Hibernate your computer, Windows saves the contents of the system memory in the hiberfil.sys file. As a result, the size of the hiberfil.sys file will always be equal to the amount of physical memory in your system. If you don't use the Hibernate feature and want to reclaim the space used by Windows for the hiberfil.sys file, perform the following steps:

  -Start the Control Panel Power Options applet (go to start, settings, Control Panel, and then click Power Options).
  -Select the Hibernate tab, uncheck "Activate the hibernation", and then click OK. Although you might think otherwise, selecting never under "Hibernate" option on the power management tab does not delete the hiberfil.sys file.
  -Windows remove the "Hibernate" option on the power management tab and delete the hiberfil.sys file.

  You can control the amount of space your system restore can use...

  1. Click Start, right click my computer and then click Properties.
  2. click on the System Restore tab.
  3. highlight one of your readers (or C: If you only) and click on the button "settings".
  4 change the percentage of disk space you want to allow... I suggest moving the slider until you have about 1 GB (1024 MB or close to that...)
  5. click on OK. Then click OK again.

  You can control the amount of space used may or may not temporary Internet files...

  Empty the temporary Internet files and reduce the size, that it stores a size between 64 MB and 128 MB...

  -Open a copy of Microsoft Internet Explorer.
  -Select TOOLS - Internet Options.
  -On the general tab in the section 'Temporary Internet files', follow these steps:
  -Click on 'Delete the Cookies' (click OK)
  -Click on "Settings" and change the "amount of disk space to use: ' something between 64 MB and 128 MB. (There may be many more now.)
  -Click OK.
  -Click on 'Delete files', then select "Delete all offline content" (the box), and then click OK. (If you had a LOT, it can take 2 to 10 minutes or more).
  -Once it's done, click OK, close Internet Explorer, open Internet Explorer.

  You can use an application that scans your system for the log files and temporary files and use it to get rid of those who:

  While probably not 100% necessary-, it is probably a good idea at this time to ensure that you continue to get the updates you need.  This will help you ensure that your system update is ready to do it for you.

  Download and run the MSRT tool manually:

  and...

  Download the latest version of Windows Update (x 86) agent here:

  Now that your system is generally free of malicious software (assuming you have an AntiVirus application), you've cleaned the "additional applications" that could be running and picking up your precious memory and the processor, you have authorized out of valuable and makes disk space as there are no problems with the drive itself and your Windows Update components are updates and should work fine - it is only only one other thing you pouvez wish to make:

  Get and install the hardware device last drivers for your system hardware/system manufacturers support and/or download web site.

  If you want, come back and let us know a bit more information on your system - particularly the brand / model of the system, you have - and maybe someone here can guide you to the place s x of law to this end.  This isn't 100% necessary - but I'd be willing to bet that you would gain some performance and features in making this part.

• Anyone have information about the software to improve the performance of a computer called "MECHANICAL SYSTEM"

  original title: windows xp

  has anyone information about the software to improve the performance of a computer called "MECHANICAL SYSTEM"?

  It is located on the website at WWW.IOLO.COM.

  Maybe someone of expertise of knowledge about this software?   or maybe someone has experience with this product?

  There is a similar product, without the costs?

  DO NOT BUY OR INSTALL "SYSTEM MECHANIC".

  IT will bog your system with errors, which would mean probably a complete restoration of your system.

  Dell recommends and sells it from their technical support group and SHAME on THEM for DOING SO.

  THIS SOFTWARE IS A TRAGEDY IN THE MAKING.

  Go to PC Mag reviews and you will see for yourself that there is a very LOW RATING and under normal conditions, you need software to mess with your registry.

  I know someone who has installed this program and we always try to fix all of the errors generated by mechanical system.

  We did a complete restoration and stil having problem.

  Thus he PURCHASE a CERTAINLY DO NOT GOLD INSTALLER CE PROGRAM.

  Here are a few methods:

  • Run msconfig.exe, and then uncheck the startup tasks that you don't need. No matter what you disable, Windows always starts.
  • Use a light virus scanner, for example Microsoft Security Essentials.
  • Replace your magnetic drive with a Solid State Disk (SSD)
