• I want to disable the USN journal because of the huge size and fragmentation

  In fact, I decided to use Windows again after 7 is out and seems relatively stable.  I've been a Linux user for many years.

  I want to disable the USN journal because of the huge size and fragmentation; I am not concerned about its performance in the fragmentation, I am concerned about the fragmentation of other files that it encourages rather SHORT time same amounts.  Not all programs have created allowances size correctly when creating new files so even a new file which was one copy of another (100 MB) can be fragmented over 30 times in a NTFS FS relatively fully defragmented.

  Microsoft?  HOW DO DISABLE YOU THE USN JOURNAL IN WINDOWS 7?  Not "How can I clear this" or "how stuck junk to existing articles"...  How is it DISABLED?

  However, I am sure that you can not turn it off for the system volume.

  You will get a response from Microsoft here.

  Just one extra point. I guess that you are talking about the \$Extend\$UsnJrnl:$J metafile; It is a fragmented NTFS file. The oldest entries are reset to zero while the file increases so they don't take any physical disk space. Actually used disk space may not exceed greatly MaxSIze + DeltaAllocation.

• workflow and fragments

  Hello

  I have a problem, I need to access a fragment within an another taskflow, how can I do?

  For example:

  I have a flow that controls the following:

  Edition of research - visualization - confirmation (after validation)

  and another stream:

  creation - confirmation (also after validation)

  My confirmation 2 options:

  1st - go to another page (easy)

  2nd - edit profile, I worked

  Basically, I want it to work, say like a ping-pong ball, between edit mode and the mode of Confirmation.

  As I see it, I have to be able to call a fragment of another stream and keep all the options that fragment as.

  Am I correct, or there is another way to do what I want?

  My version of jdeveloper is 11.1.1.7.1.

  THK in advance

  You can use a variable pageFlowScope in each workflow that has a value that contains the name of the stream - this should be accessible from each fragment in the stream.

  You can also change the setting of the page to a specific fragment.

• Set initial focus point in the middle of several models, the flow of tasks and fragments.

  Hi guys,.
  
  With the help of JDev 11.1.1.4.
  
  I've got the fragments of the page for which I would like to set the initial focus. The problem is that, often, these pages of .jsff are nested in page templates, model train, dynamic regions, etc. AFAIK, the original goal of a component is on the document. The trick is to find what all the prefixes are before the .jsff component.

  pt1:dynamicRegion:3:pt1:t1:0:it1

  Y at - it an easy way to understand all of the prefixes before that: it1, which can often be radically different?
  
  The easiest way would be to set the initial focus to say "defaultFocus" and have each .jsff has a component id called "defaultFocus? Feels like cheating, but any other way I can think seems much too complicated.
  
  Thank you

  The method we use is mainly programmed by: Marianne Horsch.

  Once again, 1 page:

  In the body of this page is a dynamic region, that's all that is never updated.

  Bean, not all record deleted etc.:

    private static final String DEFAULT_COMMAND_ATTRIBUTE = "defaultCommand";
    private static final String INITIAL_FOCUS_ATTRIBUTE = "initialFocus";
  
    private String defaultCommand;
    private String initialFocus;

      super();
      initPage();
    }
  
    public final void initPage() {
  
      List childrenList = getPageChildrenList();
      if (!childrenList.isEmpty()) {
        UIComponent defaultCommandComponent =
          UIComponentUtils.findComponentWithAttribute(childrenList, DEFAULT_COMMAND_ATTRIBUTE);
        if (defaultCommandComponent != null) {
          defaultCommand = defaultCommandComponent.getClientId(FacesContext.getCurrentInstance());

      List list = new ArrayList();
      if (root.getFacetCount() > 0) {
        Map facetMap = root.getFacets();

    private static List getOwnChildren(UIComponent root) {
      List list = new ArrayList();
      if (root.getChildCount() > 0) {
        for (UIComponent child : root.getChildren()) {
          list.add(child);
          if (child.getChildCount() > 0 || child.getFacetCount() > 0) {

          }
        }
      }
      return list;
    }  
  

  Dynamic region is based on a bean of support as well.
  As I said before, when you want good use beans ():

• Difference between subview JSF and fragments of the Page in ADF Faces

  Hi, what is the difference between the use of JSF subview tag and ADF Faces page fragments.
  
  It's between these two-
  
  < f: subview id = "header" / >
  < jsp: include page = "Header.jsp' RAS ="true"/ >"
  < / f: subview >
  
  and
  
  including directly a fragment of a page (with an element of jsp:root outbreak) as below
  
  < jsp: include page="/fileExplorer/popups.jspx"/ >
  
  Thank you

  The subview is a naming container which ensures that no violation of ID of component unique is caused by the imported page fragment. Use the component subview, all IDS of any fragment component are prefixed with the id subview followed by a colon

• Where can I find the latest research on Solaris 10 zfs and without?

  I know Arul and Christian Bilien did a lot to write about storage related to Oracle technology. Where are the latest discoveries? Of course, there are some exotic configurations that can be implemented to run the optimizer, but is there a set of "best practices" that usually work for 'most people'? Are there common advice for people using Solaris 10 and zfs on SAN hardware (IE, CEM)? Double-stripe must be configured with meticulous care, or it works "well enough" just by taking some rough assumptions?
  
  Thank you very much!

  Hello

  I have a few links that I used:

  http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide

  These are not really new, then you may have encountered them already.

• Downloaded albums divided and fragmented

  A few albums that I downloaded and opened in Windows Media Player appear as separate albums with the split rails.  Does anyone know how to fix this?

  Hi Jeff

  Quite often the tracks on the albums eventually be downloaded from same or different album versions a 'greatest hits' compilation - WMP takes the info in the track properties if you end up with this kind of mess!

  Click on the different tracks in WMP and select "Open File location" and then check the properties of the file - tab "Détails" and you will almost certainly see the differences here. Change the properties in the tracks that are wrong (you can do it on multiple tracks to save the effort) and they must stay put. * -Cheers, Ric.

  * If they are not your wmp setting options may require setting - back if necessary.

• Hidden table reappear on submit, fragment and button appears not

  Hello

  I'm new to JavaScript and wish assistance.

  I have three tables in a form. Users can delete these tables if them is not necessary by pressing a button called 'no '. This command sets the presence of table "Hidden."

  I have a button on the form to submit (not an actual submit button) that is subject to some validations and then sends it by electronic mail.

  The code works with the exception of three questions. The first is that any table (Orientation, SkillDevelopment, ExamPrep) that I have "hidden" to reappears on submit. I want that they remain hidden after the submission. A 'fragment' (OfficeUseOnly) that I created that I would like to be included on submit is not, and my selection button (a hidden button) does not appear even if I put his visible presence in my JavaScript on the click event of send.

  I work on the assumption that there is a problem with the code (which occurs for the click event of button that sends the form) below somewhere that makes these things occur, or in the case of my appearing ellipses and fragment, not the case.

  I used this code in other forms, with slight variations, and everything seems to work ok although other forms do not include an element that was hidden before.

  Just a note: the BankDetails, print and SaveAs "hidden" all works ok. Where I'm going wrong?

  Here is the code

  var boValidation = true;

  If (Orientation.presence == "visible" & & Orientation_Subtotal.OreintationDocs.OreintDocsNo.rawValue == "2" |) SkillDevelopment.presence == 'visible' & & SkillDevSubTOtal.SkillDevDocs.SkillDevDocsN0.rawValue == '3 ' |

  ExamPrep.presence == 'visible' & & ExamPrepSubTotal.ExamPrepDocs.ExamPrepDOcsNo.rawValue == '2')

  {

  boValidation = false;

  App.Alert ("you etc...");

  BodyConfirm.presence = "visible";

  }

  If (boValidation)

  {

  var var0 = xfra.resolveNode("Details.email").rawValue;

  var var1 = "travel and spending bill:"+ xfa.resolveNode("Detail.NameComapany").rawValue; "

  event.target.mailDoc({)

  bUI: false,

  cTo: "shapes",.

  cCc: var0,.

  bassujetti: var1,.

  CMSG: "Thank you for submitting your form...". »

  });

  BankDetails.presence = 'hidden ';

  Print.Presence = 'hidden ';

  SaveAs.presence = 'hidden ';

  OfficeUseOnly.presence = "visible";

  Ellipses.Presence = "visible";

  }

  Just a reminder that I know very little about JavaScript. The code above was driven to someone else that I adapted to my needs.

  Thanks in advance.

  Hello

  Form... Properties... Run-Time... Keep script changes, it is set to automatic or manual.  Manual means that you need to restore the values of presence yourself whenever the form is opened.  You probably wont auto

• format hard drive for windows and larger files, TV supports

  Hello

  pls suggest me with the solution to the following problem.

  I need to know what format of hard drive works with mac, windows, & TV too, even for large files and quality bluray movies

  FAT32 only supports files up to a maximum size of 4 GB, which would be certainly much too small for Blu - Ray quality media.

  exFAT supports files of unlimited size effectively, Mac and Windows can read and write to exFAT to format external drives but neither can boot from such a unit. If a TV or other system supports exFAT drives, you need to check yourself formatted.

  NTFS supports files of unlimited size indeed, Mac can only read NTFS, it cannot format or write to NTFS, unless you get an add-on. Of course Windows supports NTFS. Again, you will need to check if your TV etc supports NTFS. If you want to add full support for NTFS to a Mac, I recommend this - https://www.paragon-software.com/home/ntfs-mac/

  HFS + is the current format of Apple and new supports files of unlimited size effectively. Mac can of course read, write and format disks. Does not support the Windows as a standard HFS +, but still, you can buy an add-on for Windows Add this feature. It is extremely unlikely that a TV would support HFS +. If you want to add full support for HFS + for Windows, take a look at this - http://www.mediafour.com/software/macdrive/

  There are also other formats of disc for example ZFS and BTRFS, Ext3, Ext4 and soon SATF, but in this case, they are not relevant.

  Note: as indicated above, in many cases, I said 'actually unlimited', it is of course a limit, but one so great that he will strike you not for individual files, including Blu - Ray or even files UltraHD (4 k).

• Move the "Data Service" volume ZFS on OSX Server

  Hi all

  I would like to move all the data service to a ZFS volume on a Mavericks OSX Server. This option can be found here:
  Server.app-> your server-> settings
  and is called "Data Service". As someone has already done this? It works or what I have to do a manual config, whenever the server restarts?

  Hi all

  So I'll answer my own question.  The answer is no, in fact, the app Server does not detect even the zfs volume.  I also try to cheat and to synchronize the/Library/Server volume ZFS and softlink then the original file to the copy of the zfs volume, but App Server would no longer work.

  Then Mac OS x still don't like ZFS much.

  I reformatted the drive with appleRAID, and then I could move everything using the button in the application.  I noticed that this original file is still there.  If it's really just an arrangement written somewhere.  Anyone know where this parameter is written?  Maybe I could get data on the ZFS drive sync and write this setting by hand.

• I have Windows XP and my PC gets slower and slower

  I have Windows XP and my PC gets slower and slower

  Well, if you have a slow computer experience, it is a serious performance problem.

  There may be several reasons for the performance decline computer day after day, most common are the following:
  -Inadequate system or RAM, memory
  -Too many unnecessary things and fragmented in the computer files
  -Programs that run in the background and consuming system resources
  -Activity, virus, Spyware and Malware
  -Several Antivirus running in the system

  I guess if your computer worked well at the beginning means that you have good amount of system memory or RAM memory, but it is recommended to increase. Otherwise, you can do away with the increase in the virtual memory or paging file.
  Right click on my computer go Properties. In the System Properties window go to the Advanced tab.
  Now, click on the settings buttons in Performance. The Performance Options window click on the Advanced tab again and you will see the virtual memory down. Click on change. Now, you can keep it managed system or Custom. If you use the custom, then make sure that the initial size is 1.5 times the physical memory is actual and the maximum size is 3 x times.
  Then apply and close all windows and restart the computer, note any change in performance.

  To clean all the unwanted files just use the disk cleanup utility, it will clean up all unwanted computer junk files. Then you can go ahead and use Disk Defragmenter to defragment all the files fragmented in the c: Drive.

  Prevention of the execution of unwanted programs must be done with caution. Sometimes programs load automatically whenever the computer is turned on these programs to continue to run in the background and consume system resources. The best thing to do is to stop them from loading automatically. Click START and then click RUN. RUN window opens upward, in the type of window run msconfig, system configuration window opens. Click on the last tab that says startup. You will see the list and most of them will have a check. First of all to uncheck all the, then control selectively the most important like your Antivirus, Internet connection, modem, another important application driver tool that may be necessary. You can hardly but understand that those check must sound familiar to you. Apply and then restart the computer. When the computer restarts, you will see a prompt that saya that you have used the System Configuration utility. Simple uncheck the box at the bottom and click OK. Notice the change in system performance.

  If you run more thn an Antivirus, make sure you uninstall one. Since then, most of the antiviruses have a real-time scanner or resident shield that consumes some system resources, using several will cause more consumption of system resources. Subsequently, slow down the computer.

  If all of the above does little to improve the performance of the Virus issue might have to be declared. However, let me know and we'll do something if it's a virus problem.

• E2000 router and the NAS QNAP TS-212

  Hello

  I've been a happy user of a quite old WRT54G and a NAS QNAP TS-212 for quite awhile.

  But recently, the router is dead so I bought a new - this time, the model E2000.

  Since then, the AFP (Apple protocol) connection to the NAS Server works only for a couple of hours after reboot of the router. I tried to restart the router and the NAS - only restart the router allows, in addition he has worked with the former, so I guess the E2000 is to blame.

  The connection through the web to the NAS works all the time.

  Any ideas where to look for a potential solution? How to diagnose what the problem?

  Kind regards

  Adam

  Does this happen with wired or Wi - Fi?

  Connect the computer to the router with the Ethernet cable and check to see if you face the same problem with the wired connection.

  If it is with the wired connection too, then try the following.  In this case, you can try to reduce the speed of the LAN. Here are the steps:

  START--> right click on my network places, and then click Properties

  Right-click on the device, and then click Properties

  Click on the button set UP

  Select the ADVANCED tab and settings, you can change appear on the left.

  If the problem is with the Wi - Fi connection and then try to change some advanced on the router settings wireless.

  Open the router configuration page and go to the tab settings wireless wireless Advanced tab Change the tag to 75 interval, RTS threshold and fragmentation to 2304. Save the settings.

• E4200 and Arris TM702B cable modem

  I bought this router and expects a lot from it, but not what happened when dl a file: its starts enthusiastic and reaches up to 8000 Kbps, but unfortunately my cable modem loses internet contact then (seems to reset or accident or both). My network is fine, it's just the internet connection.

  I have updated the firmware of the E4200 (FW_E4200_1.0.02.013_US) and reset the router: no joy.

  Claimant stated that my modem is OK, but that leaves me with this annoying problem!

  Can someone help me please?

  Try these steps-

  Move the far the arris of telephone cable modem router... use of cordless telephones 2.4 Ghz also run a speed @ speedtest.net test and a ping test @ pingtest.net, and also keep all wireless phones away from routers, I found a huge improvement in my router speeds and no lag or dropped connection! also tips to improve your speed-

  MTU - MANUAL - 1365

  CHANGE THE BEACON INTERVAL-75

  THRESHOLD RTS AND FRAGMENTATION-2304

  FILTER ANONYMOUS INTERNET - PEOPLE WITH DISABILITIES REQUESTS

  FILTER MULTICAST - PEOPLE WITH DISABILITIES

  FILTER INTERNET NAT REDIRECTION - PEOPLE WITH DISABILITIES

  FILTER IDENT (PORT 113) - ENABLED

  QOS - WMM - ACTIVE

  UPNP-ENABLED

  SAVE THE SETTINGS

  access the router to change these settings - type 192.168.1.1 and enter admin, and the password (that would be your router password) or cisco software click router connection settings then click on advanced settings, then click ok, and then manually configuring the router

  This should also improve your 5 GHz & 2.4 Ghz speeds and make sure you have wpa2 password protected it and I am sure you will find a shocking improvement as I did in the speeds and singal...

  you will see a significant improvement in singal, I discovered cela if trail and error even had cisco replace my E3000 due to connection problem when all along, it was my cable modem wireless!  I would come down the router about an inch or more away the ARRIS cable modem! Good luck! my router went from 54.0mbps to improve 144.0mbps - so try to move the router away from the modem, it worked for me and there is a difficulty

• WRT160NL connection with n and USB connection problem

  Hi guys,.

  I have the Linksys WRT160NL router and I have two fundamental problems with that:

  1. I have a laptop HP with n on its wireless card connection. (it's an HP probook 4720 s). So I know that this laptop has ability. n I have the most recent driver vor he 3.1.18. The thing is that my Linksys router does not transmit sound wireless n, just g...

  What should I do to make it work with n as well?

  2. the second issue is that the USB connection is working in a very strange way. I have attached an ADATA with USB 3.0 HDD external, even. He works in 2.0.

  I have a lot of WAV files on it and when I stream to my receiver files pay with much intrerupptions, break ups. MP3 work very well.

  I don't know what to do to solve this 2 problems... Maybe someone could help me...

  Thank you

  Try changing some settings on the router wireless.

  Connect the computer to the router with the Ethernet cable. Open the router configuration page. Go to the wireless tab and the manual value configuration view. Change the channel to 11 wireless. Make sure that the network is set to mixed. Save the settings.

  Go to wireless security sub tab and change the wireless WPA2 with AES security mode. Save the settings.

  Click the tab under advanced wireless settings change the tag to 75 interval, RTS threshold and fragmentation to 2304. Save the settings. Now try to connect to the network again.

• Wusb300n w / WRT160Nv2 - unusable! Give up the connection again and again

  I spent at least 16 hours trying to get my to work with WRT160Nv2 WUSB300N

  firmware on router is v2.0 02 last, latest drivers: ftp://ftp.linksys.com/downloads/NA/drivers/WUSB300N_20071204_dr.zip

  I use windows zero Configuration tool.  wireless monitor not installed as it was unusable.

  I can connect to the AP perfectly, but no matter what time, I try to upload a large file, say more than 10 MB, it disconnects.

  It appears after a certain amount of data is transferred, whether by downloading a large file or not, it disconnects

  This product is totally unusable.

  I've tried everything

  Current settings:

  WPA psk / tkip

  mode: joint

  the standard 20 mhz band radio (only other option is automatic)

  broad channel: 3 (grey outside, I can't change that)

  standard channel: 11

  When I tried to put the 3 above options auto same problem

  evolution of the rts and fragmentation threshold threshold did not help

  network configuration: wireless access point is 10.191.191.253 acting as a switch, connect a switchport to the Firewall ASA 5505.  DHCP is granted to ASA and disabled dhcp a wireless access point.

  again, everything works well in terms of access to the internet but connection is to move after a certain amount of bytes sent =)

  Please advise...

  Thank you

  There must be a bug in WPA PSK personal... as soon as I switched to WPA Personal 2 all problems went away.

  Is this a known issue?
