Shorting the timeout for socket connection

Hi everyone, i've got a client who owns a handle to a remote object. When the remote object quits, accesing it through a method invocation throws a java.net.SocketTimeoutException: Read timed out. That's fair, what's up is that it lasts about six seconds in sending it, and i would like to shorten the time it waits until it realises it can't connect. I've tried with sun.rmi.transport.connectionTimeout and sun.rmi.transport.tcp.readTimeout, and no success. Any idea?
Thanks in advance.

The "sun.rmi.transport.proxy.connectTimeout" parameter works only when HTTP is used.
We do it manually by utilizing RMI client and server socket factories and setting socket options as appropriate. For the connect timeout, there is connect(SocketAddress endpoint, int timeout) method of the Socket class. With this approach, the application has a full control over sockets used by the RMI engine.

I suppose it is the problem with socket connection,Please help

Hi,
I'm trying to build a chat server in Java on Linux OS.I've created basically 2 classes in the client program.The first one shows the login window.When we enter the Login ID & password & click on the ok button,the data is sent to the server for verification.If the login is true,the second class is invoked,which displays the messenger window.This class again access the server
for collecting the IDs of the online persons.But this statement which reads from the server causes an exception in the program.If we invoke the second class independently(ie not from 1st class) then there is no problem & the required data is read from the server.Can anyone please help me in getting this program right.I'm working on a p4 machine with JDK1.4.
The Exceptions caused are given below

You're connecting to the server twice. After you've successfully logged in, pass the Socket to the Messenger class.
public class Messenger {
    Socket connect;
    public static void main(String args[]) {
        Messenger mes = new Messenger(args[0]);
    Messenger(Socket s, String strg) {
        this.connect = s;

Workplace won't give me the password for wifi connection

My place of employment refuse to give me the password for wifi connection. Is there anyway around this?

Nothing legal. They do add password access for a reason.

Just bought an ipad mini. It recognizes my internet connection but doesn't connect. It shows a lock. How do I get to where I enter the password for my connection?

Just bought an ipad mini. Trying to set up internet connection. It recognizes my connection but will not load. There is a padlock shown. How do I get to where I need to enter the password for my connection?

On your router/modem, there will be a Wi-Fi password. If you enter that into your iPad for your connection, then your iPad will have permission to connect to that access point and then you will be able to use your internet.

How to extend the timeout for long running queries

I unfortunately have a query that needs to run for 2 hours (long story) to load a year's worth of data into PowerPivot (RTM). PowerPivot stops with an error after running for 1 hour. I tried changing the "General Timeout" setting from 0 to 28800
(8 hours) in the SQL conneciton settings (native client 10.0) and I also managed to get the server owner to increase the "Query Timeout" setting in the SQL Server's Connections dialog but PowerPivot still errors out after 1 hr.
A workaround will be to use SSIS to run the query and store the result in another database but I'd rather not do that if I don't have to.
Error Message
The refresh operation failed because the source data base or the table does not exist, or because you do not have access to the source
More Details:
OLE DB or ODBC error: Query timeout expired; HYT00.
An error occurred while processing the 'XXXX' table.
The operation has been cancelled.
Is there any other place where the timeout can be set or controlled that I've missed?

Try
1) Setting "ExternalCommandTimeout" in the server configuration file (msmdsrv.ini) to a multiple of seconds you want (in this case >7200, by default it is 3600(1hr)).
2) Restart the server.
3) Refresh the data.
Please let me know, if this doesn't work.

What s the solution for ' cannt connect to iTunes Store

I have just bought an ipad 3G with IOS6
Most of the time,i have not been able to download Apps which are originally from Apple or 3rd party.
The statement prompted has always been ' Cannt connect to iTunes Store '.
Pls advise me on this problem.

Hi All,
I'd like to revive this thread and ask for further clarification of why SWF reloading isn't supported in AoT builds for iOS for SWF assets that have ABC. When we package these assets using ADT it strips the bytecode from these files and packages it within the primary application SWF so I don't think that Apple ToU compliance is an issue any longer. I assume there must be a technical limiation in how the loaded SWF with stripped ABC is linked back up with it's bytecode after loading.
Is this a limitation of the AIR runtime that can be worked around in the future, or something that stems from a technical limitation of how the cross-compiled code actually executes under iOS? In otrher words, can it be fixed in a future release of AIR?
It seems to me that the promise of using AIR is the ability to target web and iOS from the same codebase. If you have an existing application of some complexity targeting web then it's likely loading assets on demand and reloading them later as needed (Ex. we have over 700 items in game that can be equipped on avatars and each is a separate SWF asset). Having to extensively modify the app's asset manager for the iOS platform crates the need for divergent codebases at the core level for each platform. It seems like this is an important flaw to address if Adobe wants to target mobile gaming.

OSB: Business Service Timeout for JCA Connection

Hi,
I am wondering if there's any way to configure timeout for a JCA connection in OSB? It's not configurable in Business Service.
Thanks.

Hi Anuj,
I am using DbAdapter. As for operation, which operation are you referring to? Where do I check to verify this?
Thanks.

What is the interface for MDD connected to monitor?

I got an used MDD 1 GHz for child, which does come with any cord or accessories. The most surprise to me is its port for connecting itself to a monitor. I cannot find an interface for connecting it to the cord of the monitor. What is the part number or where can I find the interface?
I would appreciate any help. Thank you very much.

It has 3 possible connectors for a Monitor...

Urgent:Need to add Timeout for getting connection

All,
While using DriverManager.getConnection to get the connection,I need to add Timeout in my code so if I don't get a connection with in 30 seconds,I need to say'Operation Timed out.
I was using DriverManager Api's setLoginTimeout method to set the desired time but it doesn't work.Can somebody tell me some other way to do it.

If I use this method then if second thread reports
Timed out after 30 seconds and then origional thread
gets connection after 30 seconds then it'll also
report.I dont want a connection if 30 second time
passes.I think if second thread reports 'timed out'
then I won't be able to explicitly kill the origional
thread as stop method is deprecated in Thread
class.Can you make it clear please?You can't stop the actual thread attempting the connection.
It will require some thought on your part to correctly wrap it.
It might not work at all because the getConnection() method, or something in it, might be synchronized.

How to control the timeout for StreamSocket.ConnectAsync(), and StreamSocketListener.AcceptAsync()?

I can not file API to do this.Ray_ni

Hi Ray,
Here is a simple sample...
async void btnGetData_Click(object sender, RoutedEventArgs e)
// separated all this out so it is clearer:
//Create a socket
StreamSocket aSocket = new StreamSocket();
//Cancellation token is inspected to determine if the async method should be cancelled
CancellationTokenSource cts = new CancellationTokenSource();
//In this case, after 2 seconds... signal cancel
cts.CancelAfter(2000);
//get the operation
StreamSocketConnectOperation op = aSocket.ConnectAsync(new Windows.Networking.HostName("localhost"), "22112", SocketProtectionLevel.PlainSocket);
//Create a task and pass the cancellation token
Task aTask = op.StartAsTask(cts.Token);
try
//kick off the task and wait for a result!
await aTask;
catch(TaskCanceledException tcEx)
string a = "Task Cancelled: " + tcEx.Message;
catch(Exception theEx)
string b = "Exception: " + theEx.Message;
finally
string c = "done, still might have had an exception though";
Enjoy!

How to switch off the timeout for cryptsetup on boot?

Hi,
like the title says... I have a problem with cryptsetup having a timeout value after the update yesterday. I don't want it. How to get rid of it?
Thank you in advance.

tomegun wrote:in options, append: "timeout=0"
Yes. Thank you. I found it now in the man page. This is really annoying to have a timeout there as a default setting. I did not setup any timeouts in crypttab and I thought it was a bug in some systemd stuff. Also the wiki pages are not up-to-date anymore where I've been looking first. They still refer to the old cryptsetup settings.
