  • Applet in client-server infrastructure

    - by Andrey
    Hello! I have a general question concerning client-server design. We have a Java server with Spring, a GWT client program and some HTTP-servlets for our site. At the moment we also want to develop an applet which would communicate with that server in such a way GWT-client and site requests do. Is it a good idea to communicate with the server from applet by RMI? I.e. to create some Remote services, register them with Spring and call them from applet? Thanks in advance!

  • Forward DB requests after a DB move in SQL Server

    - by Nissan Fan
    I've moved database from one SQL Server instance on a machine to another machine completely. Is there any way to forward requests to the new server automatically so it doesn't require client config changes? Keep in mind it's only one DB out of many on the original server so I can't just forward all requests.

    - by Geetha
    I am trying to execute this following procedure in SQL Server 2005.

For more information, contact Customer Support Services". am using the same Database and the same format. when we searched in the web it shows some fixes to be used in sql server 2005 to avoid this error but my DBA has confirmed that all the patches are updated in our server. can anyone give me some clue on this.

  • Client-server application between two computers in the same network (using boost::asio)

    - by Edwin
    I'm trying to set up a basic communication between my desktop PC and my laptop (latter one using wireless connection) both being in the same network, using the boost::asio tutorials: synchronous client and synchronous server (in c++). When I run both the server and client on the same machine (using the localhost and the datetime port as parameters), it works splendidly. But if I try to set up the laptop as server (tested it with netstat -anb from the command prompt, it is indeed running and listening to port 13 as it's supposed to, and I even deactivated the firewall to make sure it doesn't cause any problems), I cannot connect to it with the client (set up on the PC), no matter what IP I tried (localhost, and basically any IPs that ipconfig -all gave me). So no matter what I tried, I cannot find the correct address that which the client can use to connect to the server. Could anyone help me please?

  • Access to SQL Server 2005 from a non-domain machine using Windows authentication

    - by user304582
    Hi, I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I thought that it would be a simple matter of doing something like this: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); However, this fails: the client-side error is: System.Data.SqlClient.SqlException: Login failed for user 'domain\user' and the server-side error is: Error 18456, Severity 14, State 5 I have tried various things including setting integrated security to true and false, and \ instead of \ in the User Id, but without success. In general, I know that it possible to connect to the SQL Server 2005 instance from a non-domain machine (for example, I am working with a Linux-based application which happily does this), but I don't seem to be able to work out how to do it from a Windows machine. Help would be appreciated! Thanks, Martin

  • Register a dll in Windows Server 2003

    - by Karee
    I'm trying to register some DLLs for a particular application but having some problems. The DLLs are stored in the application folder in the D: drive. I run cmd.exe, go to the D: drive and run regsvr32, but it gives me the error: "The was loaded, but the DllRegisterServer entry point was not found. This file cannot be registered." After searching for other solutions, I also tried copying the DLLs into the C:\WINDOWS\system32 folder and running regsvr32 directly there but that didn't work either. It gave me the same error. I'm not very familiar with Windows Administration, so I may need detailed instructions/explanations. Any help would be greatly appreciated! Thank you very much!

    This is the program I am trying to run: $host = "127.0.0.1"; $port = 25003; // don't timeout! set_time_limit(0); // create socket $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create socket\n"); // bind socket to port $result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n"); // start listening for connections $result = socket_listen($socket, 3) or die("Could not set up socket listener\n"); // accept incoming connections // spawn another socket to handle communication $spawn = socket_accept($socket) or die("Could not accept incoming connection\n"); // read client input $input = socket_read($spawn, 1024) or die("Could not read input\n"); // clean up input string $input = trim($input); echo "Client Message : ".$input; // reverse client input and send back $output = strrev($input) .

  • How do I install informix odbc on windows server 2003/2008?

    - by zombiegx
    I installed the informix client sdk on my pc (32 bit) and on the server, I could create an odbc connection on my pc easily, but on both windows 2003 and 2008 (64 bit) I can't. I don't know if there is a 64 bit sdk, maybe this is the issue. But I haven't found what to do. I need to use odbc since using the sdk by itself hangs IIS, and according to this post http://forums.asp.net/p/1269896/2425034.aspx#2425034 the solution is to use odbc. thanks

  • Could it be sane to use Windows Server 2012 as desktop

    - by nCdy
    what about using it on desktop? I've got enough strong PC with intel core i7 and 8GB Ram so what should I think about: why not? Were looking about major differences compared to windows 8, found less. for example new file system - can it affect me? In my usual day I need development instruments alike visual studio, virtualization tools, and some games So far I can't find something that must stop me, everything I need can work (seems like) there. Tell me why I must not do it or if that is sane to do.

  • Good Documentation on Avaya IP Office 500 r2 setup

    - by Cliff Racer
    I have set up a couple of Avaya IP Office systems over the course of my current job. I have a pretty good handle on the process, but now I am faced with something I have not done before. Both the IP office systems I have set up used all Digital phones. The new system we are putting in place will actually use IP phones for the first time. After tyring to track down some general documentation on my own, I was not able to find anything that left me feeling comfortable about setting up IP phones on an Avaya IP Office 500. Does anyone know of any good how-To's for setting up IP phones on IP Office? I get the impression its pretty simple but learend enough about Avaya to know that there are some tricky aspects to setting them up

  • Server 2012 intermittently fails to respond to pings from single host, even with firewall disabled, but responds to non-ICMP requests fine

    - by James Westbury
    This one is kind of weird. I've got the following machines involved: DC01 - 10.1.2.42, Server 2012, domain controller & DNS server, physical machine nagiosv - 10.1.2.35, CentOS 6.4, Nagios, virtual machine CB01 - 10.1.3.81, Ubuntu 12.04 LTS, couchbase server, virtual machine So, I noticed something was wrong while configuring this new Nagios VM. I started seeing DC01's state flapping. I logged into nagiosv when I saw this happening, and attempted to ping DC01, both by FQDN and its IP address. Neither worked. I tried pinging the machine from CB01, which is another VM on the same virtual switch/physical NIC as nagiosv, and that worked fine. Pings still failing from nagiosv at this time. DC01 is also an internal DNS server, so I ran dig google.com from nagiosv, and was able to run a query against DC01 just fine: ;; Query time: 1 msec ;; SERVER: 10.1.2.42#53(10.1.2.42) ;; WHEN: Fri Nov 1 07:53:51 2013 ;; MSG SIZE rcvd: 204 Pings still failing from nagiosv, though. I can ping from DC01 to nagiosv, and that works, and I can still ping from other VMs on the same physical NIC into DC01, and that works. I should mention at this point that I've disabled the firewall on DC01 for testing purposes, and it doesn't make a damned bit of difference. (Even with the firewall enabled, I have a blanket exception for ICMP from the local subnet, so it shouldn't make a difference, but I figured I should test it anyway.) I loaded up Wireshark on DC01 and pinged it from nagiosv again. What I see is a bunch of echo requests coming in and not a single reply going back out. Filtered results here, showing all ICMP traffic during a 15-second period. A few more bits of info: There are no IP conflicts on the network. MAC addresses on the incoming pings match the MAC on the VM. There are no duplicate MACs on the network, as far as I can see. I have absolutely no idea why DC01 is failing to respond, here. Any ideas?

  • Dates not recognized as dates in pivot table pulling directly from SQL Server

    - by Michael K
    My pivot pulls from an external data source with a date column. Excel doesn't see this column as a date and the 'Format Cells' option panel doesn't change how the dates are displayed. The cell data is left-aligned, suggesting a string rather than a date. I have tried cast(myvar as date) and convert(varchar, myvar, 101) and convert(varchar, myvar, 1) in the base table, but none of these have been picked up by Excel as dates. If the column is recognized as a date, I can group by week and month. I understand that if I can't fix this, the next step is to add columns with weeks and months for each date to the table, but I'd like to give formatting the column one more shot before doing that.

  • How to get data from a borked Windows Home Server

    - by harhoo
    Yesterday we had a power surge, followed by a power outage. This left my WHS borked: powering on just gives to a flashing blue light (the led on the power supply also flashes green) - no fan or boot activity, nothing. I urgently needed some files off there in the short term (and the 500GB of photos, music, personal video etc in the long term) so I took the hard drive out and put it in my computer. The files and folders showed up, but I couldn't access them - clicking on an image gave an invalid image error in Picasa, I couldn't play MP3s etc. I changed the ownership and permissions of the files, still nothing. I booted in with a LiveCD, the same: files appear, but won't open. Is there anything else I can do? I'm now wondering if it was just the power cable that's broken, but if so, why can;t I access my files from the hard drive? If it is the power cable, and I replace that and the hard drive, will I have done any harm messing around with ownership and file permissions?

  • Windows Server 2003 Terminal Services error

    - by Adrian S
    Hi! I have a Win2K3 machine which I want to access via remote desktop. When I try remote desktop on another machine the session just ends as soon as it attempts connection. I never see the log-on sceeen or anything. It just returns to the remote desktop connection dialog. I have checked the service on the target machine and it's up and running, so how can I determine the error? Is there any way to re-install terminal services and see if it just fixed?
