• Series communication between computer and cRIO

  Hello

  I am not new to Labview or cRIO programming, however, venture in for my first try at the serial communication.  I have a controller (not original NOR) that sends data over a serial RS232 network I want to open a parallel session to the data that I collect with a cRIO.  Before we get to integrate, I try to test with a series, my computer cable and hyperterminal communications and the serial port cRIO.  I followed and validated exploitation and drivers with the following text:

  How to do a loopback Test series
  http://www.NI.com/white-paper/3450/en

  However, when I try to use the following example, I get nothing:

  Transfer data between cRIO and host series
  https://decibel.NI.com/content/docs/doc-3816

  Any ideas on where to start?  I appreciate very much all the advice.

  Thank you.

  I have confirmed that it is a right.  I'll try a null-modem cable.

  Thank you!

• What is the difference between virtual and physical CPU cores?

  I understand one is virtual and the other is physical. My question is, if I run a physical system with two physical processors quadricoeurs, which would be an equivalent virtual machine configuration, assuming I use VMware on a dual CPU quad-core server?

  Would be - this 4 x vCPU or 8?

  Run perfmon to see what treatment power is actually using a period reasonable period (x days)...

  You generally assign virtual servers less vCPU than you should in physical cores before conversion, or building a VM... Where you had processors dual core quad now, the reality of things would be that it is really only with the power equivalent of two hearts (crete)...

  Beauty to go with a virtual server is that you can assign a n vCPU VM start (for example, two for a multi-thread aware or SMP, application server) and add later if the performance requires it. The majority of the VMS is built with one vCPU to start, unless you KNOW (beyond doubt) that demand on the server will need vCPU more and the software running in the VM actually fully benefit the granting of vCPU more to her... I have, in general, set the alarms I know where the application of the CPU is abnormally high (or above the normal threshold) on VM (email is sent)... This allows me to monitor the requests to the server and adjust it accordingly.

  You can also grant a greater share value VM for resources, so it has a higher priority than the other virtual machines when he needs these resources.

  Of course, there is much to be said for having a host server (for ESX/ESXi) who has enough power too... These days, I wouldn't recommend becomes a new server (for a production environment) with anything less than the Interior, dual Xeon 5620... Larger environments might require higher speed Xeon 56xx or maybe even 65xx or popular 75xx Xeon series with more cores per socket... This is a capacity adequate session/run planning would have come into play...

• Communication between TNS_Listener and the listener of the Apex

  Hi all
  I how communication between TNS Listener, receiver of the Apex and Apex? For some reason, I got the following error of Apex listener:

  Caused by: oracle.dbtools.rt.web.WebException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource
  .
  .
  .
  Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
  ORA-12505, TNS:listener does not currently know of SID given in connect descriptor

  I truncated messages Java object.
  
  This has happened when I tried to connect to the Apex. So I can fix it by going to:

  http://localhost:8080/apex/listenerConfigure

  then everything worked fine.
  
  My listener.ora file:

  LISTENER =
    (DESCRIPTION_LIST =
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      )
      (DESCRIPTION =
        (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
      )
    )
  
  ADR_BASE_LISTENER = /usr/local/oracle
  
  ADR_BASE_ORACLE_LISTENER = /usr/local/oracle

  My tnsnames.ora file

  INARA =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = firefly.snowdrop.com)(PORT = 1521))
      (CONNECT_DATA =
        (SERVER = DEDICATED)
        (SERVICE_NAME = inara.snowdrop.com)
     )
    )

  When inara is the name of the instance and the firefly is the host name.
  
  Is that the order of start if first the TNS Listener or listener Apex matter first?
  
  Best regards
  Val

  Hi Val,

  My tnsnames.ora is configured for an existing server and there is no client configurations like sqlplus, sql or earpiece of the apex developer. However until now the server can connect to customers without problem (I just discover that unreproducible error on 'impossible to find the SID' sometimes occurs at the beginning of the Summit, the kick-off and can be solved by waiting for a while to connect to reconnect), so again I must modify the .ora?

  No, if your database listener is configured properly (i.e., he listens to the SID that you try to connect to the network interface/hostname/ip address /... she must use), there is no need to make any other configuration, especially not on another machine.

• [fpga] Faster communication between FPGA and host in real-time

  Hi all

  I received a card FPGA NI FlexRIO (SMU-7965R) installed on a chassis PXI (SMU-8135 embedded controller). I have an FPGA program to 40 MHz, and I use a real-time program to read a particular variable of FPGA on a regular basis. I do not stream. All I need is to get the most recent value during each execution of the loop of the program in real time (hence, DMA FIFO is not a good option). I am aware that you can read the FPGA indicators in the host program (real time) using the FPGA read/write control function. I used this feature to read a certain variable of indicator FPGA, as shown in the screenshot. The RT program takes 100 micro-seconds (10 kHz), which is not fast enough for my application.

  Is there a faster method to read the latest FPGA data, or the program shown in the screenshot can be modified to reduce the time of loop RT? Any help would be greatly appreciated.

  You're talking about an RT target a sitting in the RT himself FPGA card? If so, have you tried without the IP address of the target. See this thread to see why that would make a difference.

• Real-time communication between PHP and Flex application

  My client wants to replace the buttons 'Refresh' in their Flex/PHP app with updating in real time, so as to data changes, it is pushed to the client.
  
  I came across a few articles which cover this topic, but I'm hard-pressed to find the best approach. Can someone suggest possible solutions?
  
  Any help would be appreciated. Thanks in advance.

  If your server supports K 100 simultaneous connections with push (permanent connection)

  It can be used 100K users simultaneous apps. With polling stations, it can serve more

  100 k because it opens a connection and then it closes once the answer has

  been sent, so until this client polls again it can handle other requests of

  other customers...

• NIC not the same in virtual and real computers

  I have 4 servers running with different roles. (AD, files and DB).

  Both are HP Proliant and two DELL.

  I have virtulized all 4 machines in a single server.

  With the vSphereClient, I can start the machines.

  So far so good, unfortunately the drivers of NETWORK adapter in the virtual machine is NOT the

  even the machine real and for that (I think) the virtual machine cannot start the network card.

  I Don t have the original drivers copied within the real machine, so I activate it by the console cann´t

  What can I do to make it work on the network and not only on the console

  Thanks in advance

  Well, you never have the same network card driver in e physical and virtual hardware

  what VMware is "virtualize" the hardware for the virtual machine, and it includes a set of software drivers to do (the best practice is to install VMware Tools in the virtual machines, this way you will have the best performance for the network driver).

  by this abstraction, you can move your virtual machine on server A to Server B, even if they differ on the physical network interface cards (say A server has Intel NIC and ServerB has Broadcomm NIC)

  so:

  1 - install VMware Tools on your virtual machines

  2 - create a vswitch for virtual machines, by going to the Configuration tab / on the ESX networking and select at least one NETWORK card available

  hope this helps

• Communication between Labview and Acton spectrometer via USB or RS232

  I'm trying to communicate between a PC running XP and a spectrometer to Acton 2300i using Labview.  Windows recongizes the specification and assigns it to COM3 with the correct name.  Also, the software provided with the specification can communicate with him.  However, I was unable to communicate using VISA in Labview.  I downloaded the simple read and write example vi fromt the example finder and changed the entries at 9600 baud... but I am still unable to connect.  I also tried connecting via software of measurement and automation NOR, but getting the timeout error code.  I was able to connect using GPIB of Labview for another more old Acton Spec 500i but the onle new version connects via RS232 or USB.

  The problem was simply not having a return of carrage added at the end of my order.  Thank you for your help.

• Speed of communication between workstation and server

  Is there a way when I access my router settings that I can increase the amount of time it takes to run a report on the data of my server?  All I want to do is run a report of 100 emails or more leads is entered in the database today.  But it takes so long for the server to send this info to a spreadsheet on my workstation.  Don't you think that it is a router issue?

  What is the number of your router model. These are settings that you can set your may be this could solve the problem. If you have a firewall or an Antivirus on your computer try turning it off. Login to your configuration page of the router and under configuration tab change the MTU to 1365 size and click on save settings. After that you can try to transfer the files between your computer and check how his work.

• Prevent communication between virtual machines

  Hi all

  What we have is a VLAN in our network which consists of the entry door and a selection of VM connected to it. What I want to do is to stop the virtual machine to be able to communicate with each other, far from putting each its own dedicated VLAN?

  Anyone else has any better ideas?

  Thank you

  I have.

  You must use standard vSwitch or have you allowed for Distributed Switch? If have a dSwitch you could use the VLAN private and do what you want, i.e. a larger VIRTUAL local network and still does not allow virtual machines to communicate. They would be on a "vlan isolated private" I think.

• Communication between plugin and AcroJS

  Hello

  (1) me and my colleagues are trying to communicate between a plug-in and script objects.

  We have decided to do so through PDField. After the hard work and attempts, we have created

  a field via the plugin and the value of the field can be seen the the AcroJS

  calls. The problem is that the AcroJS is unable to set the value. Why?

  (2) is it necessary to remove the object from PDField once it is no longer necessary.

  We don't care if it is updated in the document, but want to know if

  cleaning and setting/free to use API calls.

  (3) if the cos objects used to create field released?

  Kind regards

  EmergentTime.

  A PDField is an interesting approach, but not recommended for many reasons - the XFA is just a case of edge question.

  The best solution (since it is not dirty the document and allows the richest data storage) is to use a global variable in JavaScript.

  Second best would be to use metadata to the document level.

  And there are several other methods as the data in JavaScript object.

  «Your Firefox is so far.»
  Should I uninstall my version of Firefox and try again?

  Yes, you can give it a try. Because the current stable version is Firefox 38.0.5 and you use 41.0. Which is a very unstable version.
  Then, before uninstalling to download the current version from here: https://www.mozilla.org/en-US/firefox/all/
  (You will see a lot of choice of language here. You can simply download (United States) English version for windows).
