Client-server applications with problems

We use appvolumes 2.10

We are certain to have issues with client-server applications such as launch winscp and subversion.they very well, but they can not connect to servers. The appstacks work fine on own vanilla but does not work on the main image with all the policies and basic applications. When install us it manually on the main image the applications work as expected. Indications on where we can make changes on the primary image for the appstacks works? Thank you

Lakshman thanks for you the directions. I tried to change the .cfg file last week, but had no luck. It's a known with Appsense AM incompatibility. We have uninstalled Appsense & h and it seems to have solved the problem.

LabVIEW DSC Client\Server application. How to install the executable on the client.

Hi all

I'm currently programming an Client\Server application. The server application must host shared variables, and the client application must read. The client application reads the shared variable in the indicator of their connection with the properties of the indicator. I started programming and the client application and the server are in the same project. In the client application I am lie the indicator to the library in my project that has the "My Computer" as the address. My question is how do I tell the executable installed on any computer, that I wanted to use the variables shared on the server? I have LabVIEW 2009 DSC.

Thank you

If by "data binding", you hear the Variables defined on your computer, then Yes, unless you want not linked to new variables on each executable, in this case here is an example that can help.

client-server application

I intend to transfer my application written in C/C++ for playbook... Basically, the application has a client and a server process communicating via sockets... Client process has a user interface with a few UI controls components, server process will run in the background... I would like to know if the client-server application can be written on the AIR platform?... If this support is available I think using AIR/native extension for C/C++ code porting

Also, I'm new to this platform, I would like to know if there is a support to launch the 3rd party app to another 3rd party app?... Say to use above customer case must be able to launch the server process...

Not too sure how you'll be able to do on the PB, because you can't start another application. Maybe in the future they will allow applications 'start-up' to be registered.

Newbie question on a client-server application architecture
I did some stuff in Java for awhile now, but I have never drawn in the network part of this one. I followed the tutorial to Oracle and I searched some other resources on the web. I don't have a very specific question, but I would be grateful if someone could help me understand all this. My goal in this learning project is to make a server application that will accept an unspecified number of independent of a client application connections. I think that I get the basics of establishing a ServerSocket on the server, put in place the socket on the client, and then open the entry and outflow on both and start a data transfer.

Now, I think I'm stuck in a misunderstanding on this transfer. All of the examples I see seem to treat data transfers when the order who speaks on each side is already known, so you send something good after connection and that you set the other side of eligibility receive something after the connection, and everything works fine. If the order is not known, but I can't seem to understand the flow of the application logic.

Let's say that the server gets 3 connections of 3 customers and save these Socket objects in an ArrayList. Then client B asks something, and the server responds accordingly. Later, the server needs to say something to client B, then it sends information through its support and client B responds accordingly. How should I go about setting up something like that? I think I should put listeners but I can't find examples like these, or do I define the infinite loops for each socket, try to read the data?

Any help to guide me in the right direction would be much appreciated.
Think of a very basic chat client-server application. When a client connects, it receives all messages written by other customers. It can also send messages that will go to all other customers. It is very similar to your uncertainty about who will speak in the first place, the server or the client. If users wait a bit after the connection, it is likely, that the server will talk first (because another user sent a message). If the customer/user is fast, he'll talk first ("Hello World" or something like that). There are examples of these applications of simple chat on the web, just google for them. And Yes, this is usually achieved with infinite loops. Every customer will have a such loop, try to read data from the server and the server will have as many endless loops simultaneously assets (think multi-threading) given that the connected clients.

Client Server application performance impact due to the strong issue of retransmission of TCP packets

People,
I'm having problem of performance of serious application with my vSphere environment where I deployed a couple of database SQL Server stand-alone VMs (4 x VM) to be used by some applications virtual computers servers (4 x stand alone VMs) running Oracle Forms (Java) servers. Users connect from their own workstation to various geographic locations in Asia, the data center is in Australia.
User (150 users of workstations Win7) - RDP-TCP/3389-> Terminal Server VM pool (one of the 45 x VM available) -Oracle Forms app TCP/80-> Application Server HTTP -SQL Server TCP/1433-> SQL Server VM.
Somehow, report of the team of the network there are some consistent event TCP retransmit the packet between the Application Server to the database, as well as between Terminal servers.
the accident occurred in any type of scenario same ESXi host or even different ESXi
Material:
HP BL 465c G7/G8 blades on c7000 enclosure
HP Virtual Connect modules
Software:
vSphere U1 5.1 for all blades HP running ESXi and VCenter server.
All terminal Servers Server (RDSH) and the OS: Windows Server 2008 R2 SP1 STD.
Database: SQL Server 2005 and 2008 R2
What could cause the TCP retransmission on the virtual environment?

wreedMH, what kind of problem you encounter on your server environment blade HP?

What I did:

1 perform the update firmware on blade HP, ANC and also updated the drivers of ESXi for last October 2015 using HP SPP.

2. upgrade to the last update of VMware ESXi 5.1 3 b build number 2323236.

3. switch to level the latest VMware tools v10.0.5 after having done both above.

4. follow VMware KB: big packet loss at the OS level invited on the VMXNET3 vNIC in ESXi small buffers Rx = 8192 and Rx ring #1 size = 4096

Hope that helps.

Sync phone to PC Client/Server applications use what security group to access the files on PC Win 7

Programs of client server that connects to the computer from a phone and store data on the PC as the synchronization programs have what user ID and are able to write to the disk by security group file permissions. Users authenticated Internet Explorer, system, administrators, customer ID current user appears on the phone and must be enabled (admin) and the password entered to connect. If the customer is logged as administrator? How can there be two users with the same user id? One by the PC and the other on the phone. If the phone connects the PC as a user in this group what id permissions?

Question 2: If I agree a technician to fix it to my PC and fix it, what is it connected as? and what group permissions is using? How to protect against the connection later?

Thank you

vmxnet3 adapter on windows server 2012 with problem of bottleneck for MSSQL Server

Hello!
We have a server windows 2012 R2 with MSSQL server 2014.
The client software uses the jdbc for database connection. If customers make a query which collects a massive amount of data the whole thing slowed down after a while.
Then, his need to wait 10-20 minutes to speed up again. I have tested and tried everything.
-measure the ethernet parameters
-replace the cables by cat7
-installed a virtual machine with the windows client and the real customer use the virtual environment via rdp
-activated the RSS in the vmxnet3 advanced settings and windows
-the mode SplitRx in vcenter vm settings and disabled ethernet Coalescent too
-set the VM to high latency
-tried to migrate the virtual machine to another host
Not for their help. If a massive sql query is run first its great, then the need for a second or more to check a single record.
checked the vm cpu stress but its less than 5% all the time. Checked the network with wireshark, there are a lot of small packets but nothing big. The bandwidth used is still low.
When its idle delay after two packets will increase from a few ms to 400-500 ms.
Our most powerful server is an HP DL380 G9 with two octa core Xeon processor 384 GB of ram, full SSD datastore. Its a lightning fast host.
The virtual machine have 8 core cpu and 64 GB of ram.
No matter where am I up the virtual machine or how many resources provide the custom aisle question.
The strange thing is when customers slowed down I can copy large files between the client and the server with fast speed, so the slow sql.
I can solved this question if I use the ethernet E1000 instead of the VMXNET3 adapter, but E1000 have much more load and the server need to transfer big files too, not only the sql service.
Vmxnet3 much faster and have less overhead, but this question of sql, I have a problem with that. So I go back to the E1000 for now. Its slower eat more cpu but the sql connections works very well without any problems.
Can someone tell me what I can try harder to identify the vmxnet3 problem? I really need it to improve network performance and lower overhead, but the rapid sql is the top priority.
Thank you!!!

We had exactly the same problem on our SQL servers once upgraded to Vsphere6.This is due to Receive Segment coalescence feature in new VMXNET3-nics on Win 2012.

More details here: http://nickmarshall.com.au/blog/2015/7/24/vsphere-6-hardware-version-11

The best way to solve this problem is to turn it off completely in the server operating system (in the admin command prompt):

netsh int tcp set global rsc = disabled

Check with:

netsh int tcp show global

It's fast and easy without downtime or disruptions and involves no change types of nic.

After doing this on all our SQL and application servers, everything was ok.

Test the Client/Server application on device inside WiFi

Hello

I need to test my application within the company wifi network.

My application survey exception I need to properly configure the APN.

If I understand correctly it will route all traffic through external servers? In this case it will not help me.

I saw on the form that you need to be a partner with RIM, so your applications will have easier access to netowrk. Anyone know how to make a claim for this? Thare are a lot of information on the website of RIM, but I havenot found place where to put my info.

Thank you

Alexander

test your application inside the WIFI device should work without any problem

Direct TCP will not work if you have not set the APN

How do you connect? If you try to connect with deviceside = true and no APN settings it will fail

with OS5, it's easy to configure your connections, allowed etc. TransportTypes.

could be something like this:
```
ConnectionFactory cf = new ConnectionFactory();
        cf.setPreferredTransportTypes(new int[]{
            TransportInfo.TRANSPORT_TCP_WIFI,
            TransportInfo.TRANSPORT_BIS_B,
            TransportInfo.TRANSPORT_TCP_CELLULAR,
            TransportInfo.TRANSPORT_WAP2});
        isBOptions biso = new BisBOptions(seekretConnectionType);
        cf.setTransportTypeOptions(TransportInfo.TRANSPORT_BIS_B, biso);
...
ConnectionDescriptor connectionDescriptor = cf.getConnection(getMyURL());
        if (connectionDescriptor == null) {
             reason = "no Connection could be made - please try later again";
             logger.warn( reason);
        } else {
            logger.debug("current TransportType: "+TransportInfo.getTransportTypeName(
                                    connectionDescriptor.getTransportDescriptor().getTransportType()));
            conn = (HttpConnection) connectionDescriptor.getConnection();
```
You can set the TransportType Options like BISB, WAP2...

in your case affecting TCP_WIFI should work

Consistency API solves all the problems of coherence Client/Server App.
While working on consistency client/server applications, I hope that only the consistency API would be enough for the part coding mainly for the management of the caches.
It is necessary to adopt some other APIs such as 'Spring AOP + Annontation' for the management of caches through webservices, pls?

Edited by: online247 July 19, 2011 15:02
Re: "I hope that only consistency API would be sufficient for the part coding mainly for the management of the caches.

Yes.

But hiding a lot more than simple 'management' (i.e. start then get / put.) You may want to use a larger section of the API to make "in place" data processing where he resides in fact (i.e. on the server side) using input processors, etc. etc. Same read/write of data from external sources, that is the basics. Good reading to the top of the dev Guide. What coherence do (some of them not even you force to actually encode anything via the API.)

Re: "is it necessary to adopt some other APIs such as 'Spring AOP + Annontation' for the management of caches through webservices, pls?

Well, only not for the 'management' of the caches. You tend to do more monitoring and management via JMX.

But for 'access' caches...

If you want a 'web services' interface on your registry caches, it's your call, how to go about it. I had good results with Apache CXF in the past, using the standard Java Web Service Annotations to the drive. The use of the spring and Spring AOP is yours. Consistency do respect, it's just a choice that you make about how you want to achieve the specific requirements of your project.

See you soon,.

Best practices for the application of client-server (Socket)

I want to build a client-server application

(1) getting started... client creates the connection to the server and keeps the reading of data from the server
(2) server continues to send different messages
(3) given the messages view (Async) client server must be changed

I tried different finished cases against IllegalStateChangeException updating GUI

So, what is the best way to do this?

Please give an example of work.

Thank you
Vijay

Well, without testing your code, I can say that if you want to update the ObservableList in updateLobby, you must be sure that this happens on the thread of JavaFX, because only this thread is allowed to update the properties / observable (who are currently in an active scene graph).

So, I would change the code in updateLobby to this:

  @Override
  public void updateLobby(LobbyListModel[] changes) {
      final String[] ar = new String[changes.length];
      for(int i=0;i!=null){System.out.println(changes[i].getName());ar[i] = changes[i].getName();}}

Platform.runLater(new Runnable() {@Overridepublic void run() {ol.addAll(ar);}});}

Good luck!

Need help on TCP/IP port multi Client-Server

Hi all, I'm trying to develop a client-server application to disseminate data on a few numbers of random ports (defined by myself) to the data on the server TCP stream (IE another computer) in LabVIEW. So far, I created my app using the examples OR for 'Simple Client + Server data' and it works fine. I also understand that VI 'TCP Listen' could not listen to the TCP 1 connection only and a way around this is to use the idea of queues to receive & process the incoming data. The disadvantage of the idea is that the 'port' basic (IE original port) must be the same (on each client TCP) with the TCP server and it is not suitable for the use I have planned.

Basically on the side of TCP server, I need to graph/control data on different port numbers that are currently broadcast in real time to client TCP one computer. Is this possible in LabVIEW?

Anyone (gurus OR incl.) advise and point me in the right direction?

* lost *.

Hello

http://zone.NI.com/DevZone/CDA/EPD/p/ID/2739 Here you can download this component. But you can also use the TCP icons which is available in the data communications > Protocals > TCp for communication and to read and write data using flattened string Variant. I have attached a small example where I'll copy a constant string to the PC to check the connection between the client and the host server. Hope this helps you.

Is it possible to Client/Server?

Our photography club is looking for ways that we can ask our members using PS, LR and possibly items. We would like to keep things simple, with only one copy of the software resides on our server and the possibility to attach up to eight or ten student computers. Is this possible in the Adobe environment today? Yes, I see the responses that say coming: subscribe to the cloud. This is not what I'm trying to do.
Thanks in advance for your help.

Photoshop is not available as a client/server application. If it was to buy a volume for the 600 users license would be incredibly expensive. You can of course use a network for the storage of files. I'm afraid that your option here would be to have the members of the club to buy a subscription to the CC for $10 per month or as a club buy a teaching edition (but do not qualify for that) stand-alone versions are not good / educational editions. If you are interested there is a link below

Pricing plans and creative Cloud membership | Adobe Creative Cloud

A rough calculation would put your monthly costs at about £7000 per month, but with the purchase of 600 licenses, I'm sure that you get a discount of heavy, still £84 000 a year for a club won't be very convenient.

Client/server JavaFX, how FX can do server-side?
So I am ultimately design a client/server application. Now, I'm curious to know how FX itself can do.

I know that Java EE is the server side of the platform, while that for the client side (right or...?) so I was curious to know how FX fits inside, just like a RIA (Rich Internet Application).

I have seen examples such as the application of DataApp that uses the resources of the ERA with JavaFX, so I'm curious to know how, if any, limitations exist for FX.

The reason I ask is because I'm trying to know where to start with EE and there is so much information it is overwhelming, and I have no idea where to start. It seems that there are a ton of "JSR" for different tasks, and I don't know exactly what I need and that, so I'm really confused: (all.

Any ideas of how I should go about it would be appreciated.

Thank you

Ignore the JSR for now.

Follow the JavaEE tutorial.
http://docs.Oracle.com/javaee/6/tutorial/doc/

The answers to many of your questions will be clear to you when you've completed the tutorial.
-----------------
I also like the tutorials here (they are a little dated, but still topical for most as the core of JEE6 specifications that the tutorial relies on have been released 5 years ago and JEE7 has yet to be published).
https://Schuchert.wikispaces.com/EJB+3+and+Java+Persistence+API
------------
zonski has a targeted spring + javafx tutorial if you prefer to learn and to use spring than JEE (they are different technologies, which cover roughly the same functional game):
http://www.zenjava.com/series/building-JEE-applications-in-JavaFX-2-0/
-----------------
JavaFX is a setting aside of client, so there is not a lot that you would do with it on the side server.
----------------

It seems that there are a ton of "JSR" for different tasks, and I don't know exactly what I need and that, so I'm really confused all

Nobody needs JEE, just use the pieces that you want that are a good target for any project you do - do not try to use everything at once.
Many things can be learned and used on its own.

Client server of executable activex LabVIEW project with excel vba

Hi all

I submitted a ticket to support nor on this problem, but my deadline for this project is very close, so I would like to ask the community to see if someone has encountered this problem before (I hope it's ok that I'm doing this!). I did a fair amount of forum-scouring, and I didn't know this even discussed problem.

I built a labView project which is essentially in the material data and
preforms various visualizations and transformations on the data. A bit of the
Screws in this project are available by VBA Excel as a Server ActiveX with LabView and
Excel as the customer - and it works! I recently discovered I would need to do a
executable version of my project, so I'm now trying to figure out how to do the same thing
with my executable file as the server instead of LabView. Here's a simplified version are
My VBA code:

Void Button1_Click()
Dim lvapp As MyServer.Application
Dim vi MyServer.VirtualInstrument

Set lvapp = CreateObject ("MyServer.Application")

VI the value is lvapp. GetVIReference ("Main.vi", "", True)

Sheet1.cells (1, 1) = vi. GetControlValue ("Path")

lvapp. Quit smoking
End Sub

I replaced LabView here with the name of my server. The code
failure of the CreateObject method with the following error:

Run-time error '13':
Type mismatch

Things, I'm pretty sure I'm doing it correctly:
-L'application is configured as an ActiveX server in the build options
-J' ran the VI once and close/re-open it just after each build before trying the
worksheet
-In excel, VBA method is configured to reference the type library of the server.
-J' have LabView itself closed when I run the .exe

Thank you

Alex

My versions and such:
Software of NEITHER: LabVIEW version 2012
OS: Windows 7

It's interesting - I'll have to look into the issue. In the meantime, I found a solution.

It's quite mysterious, but it seems that all I had to do was make sure you only the type library of the server executable has been referenced in VBA (no LabView or OLE type library) and declare the variable app as object, rather than MyServerName.Application. Honestly, I have no idea why this works, but it does. Also, I learned that you need to use the executable file paths, which are a little different than the paths of project files.

Thank you

Alex
