• Chrashed Application LabView sometimes - OPC, DSC, database

  Hello

  I have a problem with LabView. IAM using 8.6 with DSC. I have an OPC Server with 400 Variables to read a 40 to write

  My first try was the connection to the server via Datasocket. The reading 400 variables was very fast, but writing 40 variables was very slow. Each write cycle takes 10-30 s. I need now about 300-500 ms. a second is also ok, but no more.

  After that, I created a mutual FUND I/O-Server in the library. I have create 10 variables in the same Libarary. I connect variables on the EVS to the IO server it works very well. Fast read and write. But if I use more than 6-8 variables to write shared variables that LabVIEW crashed or do nothing.

  So I used the right click on the digital control - data binding - Data Binding selection-> socket Data. On the server that I am looking for the variable on the opc server. (Example pathpc: / / localhost/BACHMANN.) OPCStandardServer.2/DeltaPOx.DeltaPOx_DAQ. DeltaPOx.DELTAPOX__HostVorg_cont_MFCVorg_C2_02_soll). It works very well. I finished the project a make an exe file. Question: the communication going on AES or directly on the opc Server?

  Now the problem:

  (1) sometimes without any reason the connection with the SPS crashed. I show the LEDs of the PSP on the buttons a numerical indicators a green led switches to red. With customer Softwarefrom the producer of SPS, the communication works very well. If the SPS an OPC server doesn't always work. Even a reboot of the LabView program do not work. I have to restart the pc. After the reboot, it works well.

  (2) once the database crashed. I use the Hyper trend to show trends in the variables. Sometimes if I open the tab with Windows Hyper trend data displays the Date of January 1, 1904. That I have to restart the database. The last time, it doesn't work and I had to rebuild the Application host.

  (3) I get an error message "Runtime Error... Tagsrv.exe. I read that this message comes only if something tried to close the database. I have the error at startup of windows messages. Sometimes, after a few minutes or hours, or days. I install LabView 2009 now. I hope that the failure is complete.

  I guess that something with the database or the OPC server is incorrect. Maybe someone has an idea.

  Sorry for this stupid English :-)

  thx for the help

  Martin

  Thank you very much!!!

  It works for 5 days without crashing. I hope that this always works, even in a year :-)

• Sometimes slow

  We use Apache with https (AES-256) to the proxy for Oracle Gateway of PL/SQL embedded (11g Standard Edition). Sometimes the system works well, but all our applications are generally extremely slow, often giving us a half page loads. The server has four hearts 2 Xeons (new 45nm), 16 GB of RAM (penalty affects what we allocated to Oracle), 6 10 k SAS disks in RAID 5 and SLES 10.2 x86_64. Because it does not work very well, we are reluctant to launch customers for this topic, and is very low, about 99.5% inactive.
  
  I have a remote desktop session to a machine running on the same gigabit LAN, and the simple page loads take 20 seconds or more. If I bypass the proxy https, everything seems better run more often, but when you look at the CPU usage, idle less than 99.3% percentage. The way faster and easier, I can think of to fix this is rewrite in PHP or in another language. Someone has an idea to find the bottlenecks?

  Hello:

  I have a Setup much like yours with Apache acts as a proxy for the EPG for my APEX application. What I did was to

  (1) proxy requests http:: port/apex/i directly served by the Apache Server (you'll map a local directory that hosts the images/CSS/JS APEX ETC)
  (2) increases the setting init database "SHARED_SERVERS" at 20. (approximately 3 times the number of expected concurrent requests)

  So far, we have had no performance problems.

• 10.11.6 not have access to the applications or browsers, slow Finder & sparadic

  Had the unfortunate experience of strike updates pending popup and el capitan starts automatically updated at 11.6.

  With the update lost access to all applications with a pop - up indicating that the file is incomplete or does not properly.  Preferences system and spot light do not work.  Finder is sparadic and often extremely slow.

  I tried the reboot via safe mode does not work.  I tried the other update through safe mode does not work.

  Downloaded the update manually and I tried to update regular and safe mode with manual down load the file.  No change.

  Used the r command to download a copy of stand-alone 11.6 and entrust the fresh.  Did not work.

  Have not been able to try to use timemachine as finder has problems with external drives where the timemachines resides. Only, it no longer responds. Refreshs after several minutes, but has yet to show the contents of the folder.

  What can we do?  Use of end 2012 mini mac.  (any experience with el capitan has been extremely negative, first upgrade to 11.4, then upgrading to 11.5 and now 11.6 were overly long and extremely difficult if manually or auto-update. None have worked smoothly)

  Can you start in recovery mode? https://support.Apple.com/en-us/HT201314

  If so, check the drive with disk (since the recovery mode) utility.

• All of a sudden all applications based on slow internet; High fan speed

  All functions based on the web significantly slow down on Sunday, July 24

  • I mean by 'slow' 20 to 100 seconds just to connect (once connected, the load times are normal, even fast)
  • hit the apps: Safari, Firefox, iTunes, App Store, etc.
  • This happens on all wifi networks that I use (each with its own ISP, speeds ranging from 25mbps/10 Mbps up to 100 + Mbps / 100 + Mbit/s)
  • whenever I use the Web apps, the fan starts up and runs at full or almost full speed (if the apps are simply open, but not actively the connection/reconnection to what anyone, while the fans slow down.)

  • Networking of Safari
  • acwebsecagent
  • nsurlsessiond
  • syncdefaultsd
  • cloudd

  None of the following helped (I tested after each change):

  • disable the plugins and extensions in Safari

• Satellite Z830: Sometimes slow WLan

  Hello!

  I have the problem that my wifi is sometimes very slow.
  It takes 5 minutes to google something.

  Home everything works fine but to (for example) in my college, I compared my wifi with laptops similar speed and they were more than two times faster than mine.

  The bitrate is allgedly to 180 Mbps.

  I use win7 and the driver is real.

  Can someone help me please?

  Thank you!
  Vanessa

  > At home, everything works well

  Does this mean that your noticed slow Wifi using the laptop connected to the other wireless LANs and only?

  In my view, this would mean that it is not a card for laptop or wlan problem but the connection/configuration problem.

  Have you noticed the slow Wifi performance using Notepad in battery mode or with an adapter connected?

• B450 USB SPEED SLOW OR IRREGULAR - SOMETIMES SLOW, SOMETIMES FAST?

  Have "Lenovo B450" for about 12 months.  Recently connect 2 drives 2 external t via USB.

  When I transfer files between them, using a synchronization program or other programs - transfer speed is very erratic.  Sometimes runs at 18 + MB per second, then the next transfer (hasn't stopped program) will quickly slow down less than 2 Mbps?  Performance is random?

  I am running XP SP3 Professional.

  The same configuration (and OS) with my desktop PC is constantly fast USB (18 MB/s) transfers between disks?

  Latest lenovo drivers installed.  It seems to be a BIOS problem - please test this on your B450 - Lenovo, please test.

  All solutions?

  I tried all the solutions for slow usb noticed on the web.

  Thank you

  Ray

  SOLVED!  or rather a workaround solution was suggested by LENOVO TECH SUPPORT - a brilliant idea - run in safe MODE, make the file transfers according to normal - I found that speed was always faster to about 25 MB/s using the same synchronization program.

  It seems that some process running in normal mode interferes with USB file transfer speeds.  Could be antivirus, checking files on the fly or something else - weird * beep * huh - Anyhoo, I'll do the transfer of large files in safe mode in the future.  Thanks Lenovo support!

  see you soon,

• In Flex application feature sometimes works and sometimes does not...

  Hello

  Please help me on this...

  In my flex application features works sometimes and doesn't work sometimes does not...

  In my project, I have 5 sections with 5 separate screens... Each screen is a module of different.

  After logining in the application:

  I'll go to a screen... First time each feature works in this form...

  Ex: I have a screen with datagrid. This user select name from a datagrid job click on the next button...

  According to the name of the selected user work, I display information on the next screen and customer names.customer whose name is a drop-down list box.

  Here is the code:

  public void populateAllOEMCustomers(event:ResultEvent):void
  {

  1) var object_CustomerList:CustomerList = event.result as CustomerList; the values of the object //Assigining the object reference variable result.
  
  (2) var allOEMCustomersCollection:ArrayCollection = new ArrayCollection(); Variable declaration ArrayColliction referance.
  
  (3) var i: int = 0;
  (4) var customerComboLabel:Label = new Sun;
  
  (5) for (i = 0; i < object_CustomerList.arryCollCustName.length; i ++)
  {
  var strCustName:String = object_CustomerList.arryCollCustName.getItemAt (i) m:System.NET.SocketAddress.ToString ();
  var strCustId:String = object_CustomerList.arryCollCustId.getItemAt (i) m:System.NET.SocketAddress.ToString ();
  
  customerComboLabel = new Sun; Dynamic Declaration of the label.
  
  customerComboLabel.name = strCustName; Assinging the customer name in the label name box.
  customerComboLabel.text = strCustId; Assingning the customer id in the text box on the Label.
  
  allOEMCustomersCollection.addItem (customerComboLabel); Addition of Lable in the referace ArrayCollection variable collection.
  }
  customerComboID.selectedItem = ' - ';.
  OEMCustomersComboID.dataProvider = allOEMCustomersCollection;
  OEMCustomersComboID.selectedItem = - 1;

  }

  This feature works very well when I visit the first time on the screen... If you go back to another screen and return to the same screen and click the button following this names combo box customer time has no customer Details... I get Nullpointer Exception and it shows the number of the line 5 (I gave the above code number..)

  If I change the first line of the code to the following: each time the feature above works fine. Not getting no not an error msg...
  

  var object_CustomerList:Object = event.result;

  If I type cast in specific class (CustomerList), the feature does not work... do null pointer exception... If I type cast to object everything works fine... In my code each time I'm typecasted for the features of the specific class is not working (gettingNullpointerExcepion).

  Please help me on this... I don't get what could be the reason...

  I am using::Flex 3, Flash player 10.1

  Thanks in advance...

  Kind regards

  Satya

  Hi Satya,

  This sometimes as in your case may not work the way you have specified the RemoteClass attribute in your AS class. Because sometimes there may be a case because before it is mapped to a server-side, you are returned to the data and so that you can not get your custom class data but as normal object type.

  So to avoid this, you can map the class server-side for as classes in the Manager PreInitialize itself as shown below:

  Specify the preinitializeHandler in your main application and write the function below. That way, too, you can map as classes on the side server. So you will have no problem referring to your application AS class types.

  You can use the same line for recording of all classes. Using this, you can remove all of the [RemoteClass] attributes on all CLASSES and attach it to the unique place.

  preinitialize = "onPreinitialize ()" "

  private function onPreinitialize (): void
  {
  registerClassAlias ("com.expeditor.ScriptAdmin.Objects.CustomerList", list of clients);
  }

  In the line above the quoted string code refer to the namespace of the class on the server side and the second is your AS class. Also, remember to import the namespace from the correspondent as a class in the file.

  Try this and let me know...

  Thank you

• Click on an application and sometimes restarting the computer

  I just bought a mac 2nd hand and by the title of this post it sometimes restarts the computer, however this is most frequent during the first 20 minutes of switching on the mac, after that it seems pretty stable.

  I'm on a processor I7, Macbook pro running 10.11.3 El Captain with 4 GB of ram

  I don't know if it's a hardware or software problem clues?

• Do a right click in the Project Explorer is sometimes slow

  I have a big project of the AF with a lot of classes and libraries. I only really use these two (lvclass and lvlib) to structure and organize the project. Right click on VI sometimes takes a terribly long time to load, say up to 10 seconds, depending on the library/class. It appears to be vaguely related to how many things the owners have libraries/classes. What exactly is causing this loading time? Any ideas how I could get rid of this significant disadvantage?

  Here is more information and a few thoughts:

  • Windows 8.1
  • LabVIEW 2015 / 32 bit (I can't say for sure, but I think that I had no such problem on earlier versions 2014 and 2013)
  • Mass of compilation of all of the project (taken as 2 hours) had no effect

  Thanks for all the ideas and resources. I'm very, very happy to announce that this particular fix https://decibel.ni.com/content/docs/DOC-44159 (fix for the issue of AF project provider performance) made my problem disappear. Time has been reduced from ~ 7 sec less than a half second. Wonderful! That, to me, proves false the idea that the mere fact of having hundreds of classes or a large AF would make your current IDE experience terrible.

• sometimes slow acquisition

  Hello

  I developed a labview application, an infinite loop which performs a reading data via Ethernet, place the contents in a specific format and saves it to an oracle DB.

  This loop time varies between 90 ms and 300 ms.

  The strange thing that happens every 30 seconds or so, it's time for this loop is equal to 6 s 9 s and quickly return to the normal rate.

  I was wondering how do you know the reason?
  I disabled the firewall, antivirus, but nothing!

  I even changed the architecture of the Ethernet LAN, with only one cable between the NOR controller Ethernet and my PC, but it doesn't change anything.

  So... How can I find what is happening and conclude the problem please? I have my doubts about the BD (may be occupied by calculations) or Windows Server 2008 service that fires every 30 seconds maybe?

  If anyone can guide me

  Thank you in advance,

  Blue_Strike,

  This looks like a perfect situation for a producer/consumer architecture. The loop of the producer runs at the speed of ~ 90 ms and acquires data from the Ethernet connection. It places the data in a queue.  The consumer loop reads the queue and writes the data in the DB. This loop can run more slowly than the producer without loss of data (so that queue is busy not).  For this success, you need to write multiple DB data sets at the same time so that the loop of consumer can 'catch up' after that the DB was napping.

  Inifintie loops are generally not a good idea. Include a stop button or certain criteria based on data that cause blocking the program.  When a stop command occurs, close the Ethernet connection, write a data accumulated in the DB, close the DB connection, and then stop the program.  If you stop the program using the button abandon, you can do any of the normal shutdown process.
