• I have several questions about performance in XP that I asked about

  I have maybe something to do with my pc which has caused several issues that I have been asking questions on this site and have yet to get solved. Maybe it's a matter of slow internet access or an intermittent problem of internet access or a busy RAM which caused these problems for me:

  • 7 + 1 end Nows to Log Off or restart
  • IE cannot display the website (goes and load when I click Refresh!)
  • Enter the network password
  • Scrolling mouse (sometimes) when I click on a link in an e-mail or on a website or open a new tab opens to the blank page
  • Yahoo Messenger which is set to autostart in the Journal, sometimes impossible to display the weather plugin and so I just click on the v Options above and select Reset to Default height and it then displays to fill this place and it is currently running. What can I do to speed up my slow sometimes Tablet?

  My Internet Explorer works fine, almost all the time and only question #2 or #4 occasionally and not very often. I need to put right at the front here saying that this isn't a malware problem and it is not a lack of program updates. If you could help me with this, just read my profile since these two are discussed in depth in my profile. I recently did a clean install and I visit unwanted websites on the internet and not much at all and I have installed Security Essentials immediately and it updates every day on its own. Also, I've updated all my programs and drivers manually and my operating system as much as possible by using Windows Update in custom update high priority mode (optional) software & hardware (optional). And I use File Hippo at each connection to find updates of programs that are available and I used another program to search for driver updates.

  I was unable to find information about malicious programs in your profile. Malware is STILL a possibility. ALWAYS. You run MBAM?

  Must you Yahoo Messenger runs at startup? (I doubt it). Plug-ins are also known to cause problems. If your plugin weather might be screwing things up.

  You have never set up a clean boot?

  Finally, you should never connect, I pointed out repeatedly. Reset must be a rare event, too.

• Question about performance statistics

  William-

  I was looking on the 'doc' House to see if there was reference to the period of time represented in the performance data given in the output of the script.

  Can you tell me what we actually with the host / cluster (CPU, memory) performance statistics?

  Also - I was wondering why "ESX/ESXi Hardware Configuration" includes CPU utilization and memory - that's just how the API works?  It just seems odd to include these data with summary material...

  Forgive the noob questions (and anything that might follow) I (FINALLY) movement in a project that will allow me to work much more consistent with the API, and this script makes so much to make my life easier.  We put the spotlight on performance and the ability of prediction, so I'll try to learn what can offer the API (overlooking DOCS 9840 & 10665 as time lost...)

  Thank you!
  Don

  These are just rough summary level a time interval counters, if you are looking for granular performance information, you will need to look in performanceManager which is the entitity wherein you will get more details.

• question about performance optimization

  Hi friends,
  
  In our project, according to the changes of condition, a developer has changed its select query.
  This query uses essentially most of the rows in a table
  (consider table_a with col1, col_2, col_3, and col_4 using oracle 10 g DB
  Col_1 is PK).
  
  The query will in a manner similar to this.

  create or replace package pkg_sample is 
     type ref_cur is ref cursor;
     procedure proc_ex(
        p_col_2   table_a.col_2%type,
        p_col_3   table_a.col_3%type,
        p_col_4   table_a.col_4%type,
        o_result   ref_cur);
  end pkg_sample;
  
  create or replace package body pkg_sample is 
     procedure proc_ex(
        p_col_2   table_a.col_2%type,
        p_col_3   table_a.col_3%type,
        p_col_4   table_a.col_4%type,
        o_result   ref_cur) is 
     begin
        open o_result for
           select *
           from   table_a
           where col_2 = p_col_2
           and     nvl(col_3, 'A') = nvl(p_col_3,'A')
           and     nvl(col_4, 'A') = nvl(p_col_4,'A');
     exception 
        when others then 
           raise;
     end proc_ex;
  end pkg_sample;

  Now, I have a question regarding the use of NVL on both sides of the select query.
  
  As our request includes not PK, its doing a table scan on the entire table full.
  
  Now, we can create a function based index... do we need to have indications for each combination? (i.e. when the col_2 is not null and col_3 is null, etc...)
  
  It don't you guys think, we can use NVL on both sides or is it possible to write the select query for maximum performance?
  
  Thank you
  Jack

  instead of NVL, I would use this:

  and   (a.col2 = b.col2
         or (a.col2 is null and b.col2 is null)
        )
  

  This way, you avoid conflicts with the coded hard 'a '.

• Satellite A350D - 20K - Question about upgrade second HDD + Temperature

  I have a question about my laptop. I have notticed it is a second location of HARD disk on the bottom.
  Is it possible to use this to increase my storage?
  And if yes, how do I do that? I don't see all the connectors.
  What type of HARD drive to use in case it is possible to use this slot machine?

  My second question is on my laptop to be very hot after a short period of use.
  I installed speedfan to record the temperature. When I start the laptop, it already is between 45 and 50 degrees.
  He stayed there for half an hour and then it starts to get warmer. When I start to use the laptop for anything, it triggers to between 70 and 80 degrees.

  This does not seem normal to me. I tried to clean the vents with compressed air, but it has not made a difference.
  I searched on the internet how to take the laptop part for proparly cleaned TI.
  But I can't so I'm looking that destroy it.

  This could be the cause and more importantly, how can I solve this problem?

  Tom

  The second HARD drive bay contains the HARD drive connectors?
  If Yes, then you can use a SATA 2.5 HARD.
  If there are no connectors, then you will not be able to use the second HARD drive

  CPU and GPU produce a lot of heat. The heat dissipation is always created then there s nothing unusual that the temperature rose to higher level.
  You can change the settings in Win 7 power management. You can set the CPU to lower performance and can increase the activity of fan, which will help lower the temperature.

• Question about temperature internal Satellite A300 ND1

  Hello

  I have a question about the temperature of the standards it of ok for my laptop and what is the normal temperature and how can I keep it low?

  Thank you.

  Hello

  It's not easy to say what a normal temperature could be.
  The temperature is not always the same and it depends on the use of the laptop.
  Usually, the temperature would increase while gaming or running applications high performance. Why? Because all devices such as the CPU and GPU would focus the heat dissipation and this leads to a higher temperature.

  > How can I keep it low
  Very simply, you can keep still low level, but you can make sure there is enough free space around the laptop to ensure good air circulation.
  Also don t use the laptop on your knees etc in order do not obstruct cooling fans.

  It s also advised to clean the fans from time to time using the jet of compressed air. These sprays are really useful and could buy in the stores of different computers.

• Satellite U405D - several questions about overheating/disassembly/upgrading etc.

  Hello

  I have several questions about my old one by Satellite U405D-S2910

  1. when it works, after 2-3 hours (I run usually small programs such as safari, msn messenger and bsplayer) CPU gets 85 to 90 C (178-188). When I play age of Empires 2 (come on, its an old game) like 2-3 hours, it stops. What could be the possible reason? Furthermore, let me inform you about the climate of the city I live, 30 c temperature - humidity 25-35% (today).
  PS. CPU is AMD Turion 64 X 2 Dual-Core Mobile Processor. Model RM-74

  2. I'm going to disassemble my laptop in order to clean its cooling units (I think at the rate of overheating is this). It does seem like a desktop computer, so complicated. Ive seen a disassembly not to not (btw, its so difficult to spell dismantling :) I think Im going to do this. What are your suggestions on this subject? experiences could help me?

  3. my laptops is Ram 2x2gb PC5300 DDR2 667 MHz SDRAM memory, I want to replace RAM memory 2x2gb MACH XTREME DDR2 1333 MHZ CL9 NOTEBOOK. Should I do it? Fit my portable, stable work? any suggestions?
  PS. motherboard chipset AMD M780V

  4 - Finally :), should I use OS 64 - bit or 32-bit OS (win7)? what OS would you use if you were me?

  Thank you.

  Hey Buddy,

  1 + 2. I think everything is related to a higher internal temperature and you must clean your laptop using a jet of compressed air. That is why it s not necessary to remove, just blow softly and soon the air through the laptop. You can buy such compressed air which squirts of each computer store I think and it takes only 5 minutes.
  You can find a useful article about this here:

  3. in my opinion he should forget this update! The speed of the RAM is related to the FSB of the CPU and as much as I know about Satellite U405D it s 667 MHz so it s already the RAM faster than you can have. Save your money and buy a larger HARD drive or in the best case a SSD that can really improve the performance!

  4. in my view, the answer is clear: Windows 7 64-bit.
  Only a 64-bit OS supports full 4 GB of RAM. ;)

• A few questions about Toshiab reocvery disk for Satellite P300-133

  Hello guys,.
  I had a few questions about unpleasant surprises of recovery:

  (* 1) * I just make recovery DVD using Toshiba Recovery Disk Creator and he asked initially for 2 DVDs - but when one has been done it does not require a second blank DVD. Is it possible all the Windows Vista system files to write on 1 DVD?

  (* 2) * if I could reinstall Windows Vista using recovery of HARD drive option (by pressing F8) without using the recovery DVD?

  (* 3) * HARD drive partitions that will be formatted (just system C: or C: and E :) using HARD drive recovery?

  (* 4) * what is DVD - Image of the hard drives or the installation of Vista recovery files?

  Its pretty bad idea to not include BONES on DVD when I paid for it.
  Thanks for all the Toshiba problems :(

  1. I think the recovery disk creator means 2 CDs. I also have a Portege M700 with Windows Vista and a DVD. I got it and after that, I have a clean install of Vista with all the drivers and tools of Toshiba. Nothing is missing.

  2. Yes, you can reinstall Vista using recovery of HARD drive option when you press F8 at startup. You don't need the recovery DVDs, but you should create a when your HARD drive get some errors or something else. If you need a new recovery DVDs, you paid for one.

  3 HARD drive and complete partitions will be formatted, so backup your data first on a DVD disk external DRIVE, USB stick or something else.
  After the reinstallation, you have factory settings.

  4. the recovery DVDs is an image of the HARD disk on the factory settings. If you perform a recovery, there are all the drivers and tools are already installed. Of course, on the disk are files of installations of Vista, but you can use this DVD on your Satellite P300. The disc cannot be used on another Satellite or on a PC.

  If you have any other questions, take a look in the user manual. There are a number in the formations of the recovery. It s in Chapter 3.

• Ask questions about the functionality of EA8500 MU-MIMO

  Dear Linksys

  I bought EA8500, and it arrived today.

  I have two questions about the functionality of MU-MIMO of EA8500 AP.

  1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?

  2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.

  This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?

  Thank you

  Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.

• Questions about discussions...

  Hello

  I have a new app to do that requires network access.

  I have read this EXCELLENT post from peter_strange:

  http://supportforums.BlackBerry.com/T5/Java-development/connecting-your-BlackBerry-http-and-socket-c...

  Because I can't use BIS - B because I'm not a partner of the Alliance, I wanted to take a look at the new OS 5.0 network API and see how it works.

  I know that network connections should be performed in a separate thread.

  I'm far from being an experienced Blackberry developer... so I have a few questions about discussions.  I looked around the Internet, read on the forum, read the documentation, did some tests and so far, I came up with this code:

  SerializableAttribute public class HTTPConnection extends UiApplication {}
  Public Shared Sub main (String [] args) {}
  HTTPConnection PAP = new HTTPConnection();
  theApp.enterEventDispatcher ();
  }

  public HTTPConnection() {}
  pushScreen (new HTTPConnectionScreen());
  }
  }

  class HTTPConnectionScreen extends form {}
  public HTTPConnectionScreen() {}
  setTitle ("HTTPConnection");
  Add (new RichTextField ("choose a type of connection :"));

  final RadioButtonGroup = new RadioButtonGroup() rbGroup;
  RadioButtonField radioButtonF1 = new RadioButtonField ("Direct TCP", rbGroup, false);
  RadioButtonField radioButtonF2 = new RadioButtonField ("WAP 1.0/1.1", rbGroup, false);
  RadioButtonField radioButtonF3 = new RadioButtonField ("WAP 2.0", rbGroup, false);
  RadioButtonField radioButtonF4 is new RadioButtonField ("BES/MDS", rbGroup, false);.
  RadioButtonField radioButtonF5 = new RadioButtonField ("BIS-B", rbGroup, false);
  RadioButtonField radioButtonF6 = new RadioButtonField ("WiFi", rbGroup, false);
  Add (radioButtonF1); Add (radioButtonF2); Add (radioButtonF3); Add (radioButtonF4); Add (radioButtonF5); Add (radioButtonF6);
           
  FieldChangeListener listener = new FieldChangeListener() {}
  ' Public Sub fieldChanged (field field, int context) {}
  ConnectionThread ct = new ConnectionThread (rbGroup.getSelectedIndex () + 1);
  CT. Start();
  }
  };
           
  ButtonField buttonField = new ButtonField ("Connect", ButtonField.CONSUME_CLICK);
  buttonField.setChangeListener (listener);
  Add (buttonField);
  }

  / * method of onSavePrompt override default to avoid being asked if I want to record every time * /.
  protected boolean onSavePrompt() {}
  Returns true;
  }
  }

  class ConnectionThread extends Thread {}
  private int transportType;
  public ConnectionThread (int n) {}
  transportType = tt;
  }
      
  public void run() {}
  ConnectionFactory connFact = new ConnectionFactory();
  ConnectionDescriptor connDesc = connFact.getConnection ("URL", transportType, null);
  If (connDesc! = null) {}
  try {}
  HttpConnection httpConn = (HttpConnection) connDesc.getConnection ();
  httpConn.setRequestMethod (HttpConnection.POST);
  httpConn.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
  OutputStream out = httpConn.openOutputStream ();
  out. Write (Integer.ToString (transportType). GetBytes());
  int responseCode = httpConn.getResponseCode ();
  If (responseCode == HttpConnection.HTTP_OK) {}
  UiApplication.getUiApplication () .invokeLater (new Runnable() {}
  public void run() {}
  Dialog.Alert ("- SUCCESSFUL CONNECTION-");
  }
  });
  }
  If (httpConn! = null) httpConn.close ();
  } catch (IOException e) {}
  System.Err.println ("IOException Caught:" + e.getMessage ());
  }
  }
  }
  }

  In fact, this code works very well... but I want to improve it, and I have a few questions:

  1. I think that right now, every time I click on the 'Connect' button, I start a new thread. I would like to end this thread in the "run" method, but I don't really know how to access the variable 'ct' from there.   Counsel on how to do it?  Or maybe always use the same thread until my application is closed?

  2. in the FieldChangeListener of my "Submit" button, I want to access the value of radio box.  I did work, but I had to do my 'final' variable  What is the right way to do it?

  3 - to display a dialog box with 'Successful connection', I just wanted to write something in my main screen.  How I do that?

  I'm just a bit confused as to just what set up when you use a separate thread.

  Thanks for your advice!

  Edit: Hidden URL I connect to...

  That's what I call a good question! (now I'm wondering why the forums do not work with opera correctly, in any case, here my baldy to the answer format): 1. your thread "dies" when it's over, no need to close it. 2 Yes 3.

• Question about the differences in commands

  Hey guys -.

  I just had a few questions about the differences between orders that seem to perform the same function.  Can you let me know if an order is more preferable to the other and what the difference is.  I would really appreciate it as it I currently practice some INE laboratories and I see that orders change from lab to lab.  Thanks advance!

  1. When you write a static NAT for specific host 1 - is - this important if I understand the 32 subnet?

  EX: static (inside, outside) 1.1.1.1, 2.2.2.2 VS static (inside, outside) 1.1.1.1 2.2.2.2 netmask 255.255.255.255

  2. when I'm setting up a router as a CA server and it is necessary to "export" the key, whatever my method of exporting the key?  If so, in which method call for which solution?

  EX: key export cryptographic rsa ciscox pem URL nvram: cisco VS. exporting key 3des cryptographic ciscox pem 3des rsa terminal cisco

  3. If I have to mark a packet with a DSCP of X value, matter if I use the 'set dscp' VS 'set ip dscp?  If so, what is the difference?

  FXY

  Policy-map X

  class X

  the dscp X value

  VS

  Policy-map X

  class X

  X ip dscp value

  I guess pertaining to 2, if i was speaking in terms of from a cisco router to another cisco router - would terminal be acceptable?
  
  

  Yes, the "Import cryptographic key" command can take a url and also from the terminal entrance. In this terminal case wil is much easier.

• Windows 7 starts questions about mac and office 2010 following an installation

  It's a long cut as short as vent. I've been miss sold a record of upgrade of windows 8 full disk-shaped, with norton and office 2010. My goal of creating windows on my mac for a course I'm taking. After that know I need windows 7, I bought it online. I created a partition of 80g on my mac charge windows 7, then norton. Until I loaded the office that I was invited to perform the update from apple in the windows software 7. Note before I installed norton, I load boot camp mac utilities according to the instructions. So, followed by all as should be. The prompt update from apple was quick time, iTunes and airport, I checked all and then updated. Then I loaded office 2010 and obtained throughout the process from the Microsoft site. On the last part of the installation, the installation failed due to a mistake of hanging iTunes. I tried again and again, I fixed the update to iTunes to add and remove the section of windows. Then, I got different errors. I decided to remove the whole score without uninstalling all programs again. When I get to the windows live, that this falls priming. I get various error messages whenever I try to start the process. As a header of Bank pool, fatal error and so on. Can anyone help? What is the damage?

• Small questions about Dataguard

  Hello

  I have a few questions about Dataguard. I'm new to DG, carry me so for the display of these fundamental questions:

  We plan to install Oracle 12 c to Win 2012 R2 with primary and physical intelligence on different physical servers. We are looking for HA solution, but cannot afford to license CARS. The two primary & Eve are going to be in the same data center connected via a 1 gigabit network. So I have a few questions related to it.

  (a) since both of our primary & Eve is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  (e) I was reading about the modes of Protection, account required to our current situation & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Concerning

  Learner

  (a) since both of our main & secondary is going to be in the same data center with good connectivity. Can I assume that although Data guard is more DR solution, in our case it would be HA solution since we have no network latency.

  Well it will not provide the level of HA that is RAC. RAC is a Transparent Application failover. With a physical standby, you need to apply some delay for a failover operation. You can implement the observer that can automate the failover and reduce the time.

  (b) is it safe to assume that where primary fails, then the day before can automatically take the role of primary education without any manual intervention, possibly using Dataguard broker?

  This isn't really the DG broker, but rather the observer you will need to implement. The DG broker automate failover. It will be the observer who "sees" (where its name) that the principal is down and initiate the failover process. To do this, the observer will use the DG broker, so it will be necessary.

  (c) so I understand that where primary breaks down, the existing connections transfer automatically from primary to standby db (most recent primary), but how my web based java application will know that more recent connections must be sent to the standby db Server (more recent primary)? I guess net Oracle has a provision to handle this? Who can be automated?

  You'll want to read on the QuickStart failover. http://www.Oracle.com/technetwork/articles/smiley-fsfo-084973.html

  (d) given that I have only 2 physical servers, can I deploy broker Dataguard on a normal PC (since it is a thin client) assuming the PC is kept in the data center and is online 24/7?

  The DG broker is required to run on the database server. The DG broker will run on the primary and standby. I think that what you're asking really anything is if the observer can run on a PC. Yes it can. However, it is probably not a good idea. A PC will not have the internal hardware redundancy, a server can have. If the PC can fail more often than to a server. And if the gods are bad, it will fail when you most need.

  (e) I was reading about the modes of Protection, account required to our current scenario & infrastructure, I choose 'Maximum availability Mode' instead of 'maximum Performance '.

  Your choice should depend on the amount of data loss is acceptable.

  (f) what is your point of view about Oracle integrated security? I hear too much on Oracle failsafe, because people generally go to a combination of CARS & dataguard for HA? We have a few additional storage that can be shared between the two servers, but I feel with literally no DG network latency can provide us HA.

  Oracle integrated security only works on Windows with a MS Failover Cluster. Real DBAs do not have Oracle on MSFC.

  See you soon,.

• Question about compression in essbase ASO

  I have a few questions about to define a dimension of compression in Essbase ASO apps:-

  1. is it a good idea to have the size of compressor in app Essbase ASO.

  2. I read somewhere that said it would not be good idea to have the compression period dimension where months YTD neighbourhoods and quarters of the year. So should we put compression on any other dimension dynamic calc and roll ups and have less none of level 0 members stored.

  3. I have observed that when we level 0 export from an ASO application with compressed size vs ASO application with no compressed dimension, there is a difference in size of data export file. I'm not able to understand why it is so. I understand the difference between the size of data (.dat file) between Tablet app vs app uncompressed file, but do not understand the difference when the data is exported to a .txt file.

  Thank you

  (1) compression dimension is not mandatory, but it contributes to the performance. The compression dimension is a dynamic dimension. We need the column headers in a data load file. Ideal compression is achieved if the number of leaf-level members are divisible by 16.

  (2) ASO tuning is an art as much as a science.  The best choice depends on the distribution of data in the database.  and it's different in each database.  Read all the information and then test the various options.  Try it with time as the compression and then try with the next best dynamic dimension defined as dimension of compression.  I've linked a doc tuning which is version 7, but has a very detailed discussion of the dimensions of compression.

  http://www.Oracle.com/technetwork/middleware/bi-Foundation/4822-tuning-Essbase-ASO-WP-133014.PDF

  (3) the format of the header (layout) of the export may be different when you use compression vs when you are not using compression.  It will certainly be different if you use another dimension for compression.  I expect the size of the file to edit when the compression setting is changed.
