What is the best method to implement the communication client-server TCP/IP of multiples?

I want to make a customer network and multiple server using the TCP/IP protocol.

I have 30 remote wireless sensors to send data to a server with LabView.  This problem is corrected.

The server has a router that communicates with the sensors and is connected to the PC via cable net.

I want to find the way the most effective communication from the point of view of resources and, above all, the response speed of the system, because I want to update the screen as quickly as possible, to send more data per second of the sensors.

I think I have (only?) two options:

(* 1) open 30 simultaneous ports and process them in parallel to decode and display the data from each sensor.
(* 2) using two loops: one to listen to new connections and the other to take the floor, placing them in the 'tail' and decoding and then each of them separately in order to display the data from each sensor. See http://www.ni.com/white-paper/3982/en/

NOTE: at the moment I have only 4 sensors tested with method 1: it takes about 3 minutes to establish communication (why?), and then it works properly.

What method would you recommend? Why?

Thank you all in advance!

I assume you mean to "Start Asynchronous Call. Which has been added to LV2011. If you are using an older version the method I posted above works fine. In fact, we always use this VI (Manager Spawn of connection, which is the one we wrote) in LV 2011 and 2012 LV.

In fact I posted this library recently. You can find the code here. That the code implements a queue-based network. You can watch as an example of a server that generates handlers for each client that connects.

  • What is the Fax man Server?

    My computer telling me that the man of fax server does not work.  What is the fax man Server

    Hi darla,.

    Possibly associated with the HP Ltwvc13n.dllfile. It seems that it is part of the Deskjet, Officejet or software or drivers (you have products HP?). If so, you can try to reinstall to see if it helps (because it can offer the possibility to use these HP products for fax).

    If this isn't the case, then you could see if it is listed in your list of startup programs . If so, disable it to see if it can prevent the error message for you. The procedure (method two) is in the link above.  If this file is not there, looking for something about fax server or HP man (unless you have an HP computer - then you need to be a little careful about what you choose) and disable them too to see if that helps.

    Go to start / Control Panel / programs and features and see if there is a program called man fax server or anything like it either sounds like what you do not recognize installed. If so, click on it and uninstall it (unless you use actually it or may want to use it at a time, as indicated in the first paragraph above).

    Go to start / Control Panel / Accessories / Services and check if there is an entry for Fax Server (or something similar) man.  If so, click it and then click stop if it is started and then click on disable if it shows automatic or manual.  Click OK to save and reboot and see if that helps.

    If this does not work, try a boot minimum http://support.microsoft.com/kb/929135.  If the problem goes away then it's just a matter of tracking down the culprit at the origin of the problem.   Follow the procedures described in the article.  Once found, remove, delete, disable or uninstall.  Once don't forget to reset your operating system to status normal, as explained in the procedures. If the problem occurs in clean mode then just restore the system to normal and reboot - this solution will not work.

    I hope this helps.

    Good luck!

    P.S., Some of these links and procedures are written for Vista.  If you have a different operating system, and then either try to use links or procedures even when (they are likely to be the same or quite close, you can figure out the differences) or searching for this procedure in your operating system using Bing or Google.

  • What is the function of server Orchestrator?

    What is the relationship between vcenter orchestrator server and the web client?

    and what is the function of server Orchestrator?

    The 'server' is the workflow engine. It holds all the configuration, workflow, resources, etc. It works / runs the necessary real when workflow and initiates communication with the 3 party systems, that it has been configured to Orchestrate. The 3rd party communication is facilitated through plug-ins such as vCenter, vRealize Automation, PowerShell, AD, Infoblox, F5, HTTP-REST, SOAP, etc...

    The 'Client' is your developer interface that allows to build and run the workflow manually. As noted by Christophe, the workflow you've built (or have been provided in the vast library of content that comes with the server) may be performed via the API REST Orchestrator.

  • What is the MacintoshHD/library/server/ServerDocs/Data folder used for?

    I use the latest version of the server software OS X on a Mac Mini with a 256 GB SSD.  I keep running out of space. The MacintoshHD/library/server/ServerDocs/Data folder seems to be where the files are placed which occupy all the storage space.  This single file is close to 140 GB. He seems to have a copy of all my files into it.

    Can I move it to an external hard drive, if yes how?

    Do I have to have the folder for the server software to work?

    This is a (known) bug in the server application. The workaround, assuming that you have no need of smb shares, is to disable smb on the file share points that you enabled.

    If you have need of smb shares, I'm afraid you can be out of luck. You can remove the data, but it will (probably) come back... He did it for me.

    I use of models, but if you do, make sure just that everyone uses the same and don't try and pass your own original work. Without a link to these models, I don't know what they are. Google brings nothing useful.

    For all of my animations Kinetic style that I have about 80 predefined animations that use expressions based on, in, and off-peak for layers. They add timing cursors to the layers. I create my project in Illustrator organisation layers in their Center rest in its position, because all my preset animations bring a view layer, let rest until just before the out point of the layer, then a flight out of the frame. I import this model of AI multi layers (usually one for each file have for each paragraph of copy, sometimes one for every sentence, in AE as a composition with cropped layers. I add an audio track I ran the speech recognition with a text file to copy in Premiere Pro to the comp. This puts markers on the audio track with the embedded words, then I cut all the layers of 3 seconds, sequence layers, then fall into my preset animations. I adjusted the points and output layers to correspond with the words, apply the appropriate animation preset as flyInRightBounceFlyOut or SpinDownSwintSlideOutRight to each layer, refine the date a bit, add any style or the adjustment of the colors to the project and then, for the most part, without ever launching a preview ram for more than a second or two, send the project for the rendering.

    The trick to almost all of this kind of animation is advance planning to production. Most of my work is involves a custom text so that most of the models are useless. Some time ago, I hit one of these projects in approximately 3 hours, including writing and recording of the audio track. Made by hand by using keyframes would have taken about 3 days. Adapting a model project could not possibly have taken less time than to use my preset animations. I would say that if you don't buy a model of you know if adjusting the calendar requires to move keyframes manually and if the animations can be saved as animation presets so you can build your own library.

    Just for fun, here's a preset for you to try. Simply adjust an in and out point of a layer, drag it to its rest position and then to apply the preset.

  • Best method for updating CompactRIO data to Server "National Instruments.Variable Engine.1"

    Hi all, I have an OPC Client of third-party I want to use for testing with the CompactRIO. Can I specify 'National Instruments.Variable Engine.1' in the OPC server, create a new item of the mutual FUND, go to a variable and then see its value. I use a CompactRIO and I want to send the updated data that I am acquisitionning of for third-party Client OPC, then, what is the best method? Currently, what works, is that I created a shared variable published to network on the LabVIEW host that I dragged in the CompactRIO project. I've created a small loop increment value every 500ms. I then created on the host computer, a little VI, who issued this national value to "" Instruments.Variable Engine.1". Now, is there a better way to do his? Is it something that can automatically fill in manually the Variable of the CompactRIO motor without publishing the shared inside a LabVIEW application variables? Thank you for your time, best regards!

    Thanks a lot for your replies, Drew,.

    I downloaded the OPC UA API and it will next week.

    Thanks again!

  • Give advice about uninstalling the database Client Oracle under Windows with multiple Oracle homes

    Hi all.

    Probably a Client of Oracle database uninstall will arrive in a Windows box, where there are several houses of Oracle:

    (1) the Oracle Database 11 g Client is.

    (2) the House of Oracle Oracle database server.

    (3) oracle 6i Oracle Home.

    I have these concerns:

    (1) do I stop Oracle Services NOT related to the Oracle Home being deleted? I guess that's not necessary, but it is recommended?

    (2) the YES program to run must be or is better to use the YES program located at removed Oracle (Oracle Client to Database 11 g in this situation)?

    "(3) I see there are additional post - installation according to section 5.3 steps"manually remove the Oracle database Client components remaining' the Oracle Client Installation Guide for Windows.

    Could someone provide the additional steps or recommendations?

    Sorry but I do not trust the windows plataform much!

    Thanks in advance!

    Best regards, Luis!

    Hello myluism,

    You can use the oracle supplied binary dinstall to uninstall oracle binaries that you can download from this url of Oracle Database 11 g Release 2 for Microsoft Windows (x 64) that looks good in your context.

    In addition, you can also uninstall the binary files by running the dinstall respecitive houses Oracle located in the path: ORACLE_HOME\dinstall.

    In short, the chips are what the telepresence server use to become more granular with use of the licenses of the screen - screen Licenses amounted to a certain number of chips the GST follows in-house - and different combinations of resolution, number of screens and audio type out the chips.

  • Beginner looking for best practices to implement my first ESXi server.

    Hello, tomorrow I will start my first company ESXi.  I ordered a HP Proliant ML350 with e200i Raid 5 controller.  I bought 4 1 TB Sata disks and plan to put them all in Raid 5 for 3 TB of data storage.  I currently have a file Win2k3 server which has approximately1.5TB of files on several physical disks spread now.  My question is how these data should be moved to the new server?  Should I build a new machine virtual server OS 2003 or 2008 and then allocate all 1.5 + TB I this one VM?  How the data will look like ESXi?  Have I not separated or just 1 virtual players a large?  Or is there a better solution?  What should I do when I start running out of space and should allocate more space to the descent to a certain VM?  I apologize if this is a stupid question, but I'm just a little confused and trying to get all oriented upward when I started on this project in the future.

    Thank you very much!

    Dave

    You can build on Windows Server as shown above, and then create a virtual disk to host your data. You can then use something like copy robo to synchronize the data from your original data source, you could kick off for a weekend and then use robocopy to just capture changes before making your actual failover. Just be aware of the limits that the other person has remarked with the 2 TB. You can select the block maximum size when you create your VMFS datastore for your data drive, otherwise the VMDK max, you create will be a little less then you are looking for.

  • Install and configure the Apache HTTP server plug-in

    Hello

    I use WL10.3 in a Linux machine.

    I have an environment where I have one WL server in a domain which is deployed with the web application

    And I have another area where I have two managed servers in a cluster that is deployed with the company.

    Now, I want to configure Apache HTTP server to make it work as a proxy with the weblogic.

    In my current scenario, the proxies of one seed server req in the cluster and that is defined in a jndi.properties.

    Now, what should I do if I want to use the Apache

    I have the following questions:

    1 forget my env, generally how to install and configure Apache HTTP plugin?
    I see that we have already seen libproxy_61.so file in /bea/wlserver_10.3/server/plugin/linux/i686

    Do I need to install the patch even then as said in http://www.oracle.com/technology/deploy/security/wls-security/2793.html?

    2. While am adding the lines in the httpd.conf file.
    LoadModule modules/mod_wl_22.so weblogic_module

    If I put ibproxy_61.so instead of mod_wl_22.so in this line?

    3. While configuring the proxy server, balancing and session replication will be assured?

    4. and for my setup, as stated at the beginning, a few lines, which may be the best architecture?

    Your help is really appreciated.

    Hi Subh
    1 so all external requests go to the single domain server with MoreWeb app. In this scenario, you don't need any additional Proxy Apache server. Because the basic concept of the Apache Web server is to route multiple applications on a cluster of managed servers. In your case, it is a single server, you don't need any additional Web front server. Now you have these EJB on another area that is clustered. I guess you use search standard JNDI to access the EJB. So, how do you make sure that only MoreWeb app requests are load balanced to the EJB. As each subsidiary request for EJB must go to MS1 and MS2 as robin in default mode. First request to MoreWeb need access EJB of MS1. Second request for MoreWeb need access EJB MS2 etc. This means in theory, you should have an Apache Web Server before the second area something like that. You have any servlet default weblogic cluster already deployed to the second area. Otherwise use that or care of apache in etc. Then in MoreWeb App when you search the EJB, make sure that you give the address Cluster and the direct port instead of the host/port MS1 or MS2. This Web server should in turn make the round robin for EJB on second domain clustered. When you get the InitialContext object instead of using empty default constructor as new InitalContext(), you may need to use something like InitalContext (aMap) new aMap corresponding to a hash table with the properties for the provider url, etc. etc. You can see the docs for more details. Here is the link for the EJB Clustering. See the section on EJB

  • What is the best method to move from an iPhoto from one Mac to another library?

    What is the I best method for export/transfer my iPhoto on MBP to the iPhoto library library on my iMac? I prefer to keep my metadata intact; I guess that to do a package contents 'show' of my iPhoto and AirDropping the 'masters' library, I won't lose it? I'm under El Capitan 10.11.4 on Mac.

    I just want to explain my situation because maybe I'm missing something. I have SUMMER will use the photo library iCloud for synchronization on all my Apple devices and as a backup off-site. Fortunately, I realized soon as enough it would become a management NIGHTMARE. I downloaded everything from iCloud to my MBP and want to get it all on my iMac, so I can clean up the mess of duplicates and others.

    I couldn't synchronize with realism of the iCloud photo library to my iMac because I would have had to download about 150 + GB of data, so that I can download the 30 or GBs who were on my families iOS devices iCloud and the MBP. ICloud photo library interface is NOT well designed or easy to use - download directly from the cloud is heavy at best.

    All tips are appreciated, thanks.

    Simply connect the two Macs together and drag the library in the pictures of the new mac folder - or use an external hard drive to the Mac OS extended (journaled) format and drag through - then launch iPhoto on the new system

    Move the masters moves original photos and metadata exactly as they were imported without organization

    And iCloud library isn't an option for iPhoto - it requires OS X 10.10.1 and photos 1 or later version
