问题 I'm writing a C++ app that will need to connect to various PLCs over modbus, the IPs of these PLCs is given by user input. Currently when the user puts in an IP that cannot be connected to, my program hangs for around 2 minutes in an attempt to connect and having my app hang for 2 minutes is not an option. An example program illustrates the issue and my attempted fixes: #include <modbus/modbus.h> #include <string> #include <errno.h> #include <iostream> #define PRINT_TIMEVAL(timeval) std::cout

问题 I need to add "test" functionality for RMI connection (checking if the server on the other side is available/existent). I have created this class/beans: public class MyRmiClientSocketFactory implements RMIClientSocketFactory { private int timeout; public void setTimeout(int timeout) { this.timeout = timeout; } @Override public Socket createSocket(String host, int port) throws IOException { final Socket socket = new Socket(); socket.setSoTimeout(timeout); socket.setSoLinger(false, 0); socket

问题 How can I set the time that Liquibase waits to establish a connection to a database server (specifically, PostgreSQL) before failing (i.e. the connection timeout)? How can I set the number of times that Liquibase will attempt to connect to a database server before aborting (i.e. the connection retry count)? 回答1: Liquibase uses a jdbc connection. According to this answer network timeout was only introduced to JDBC from spec 4.1 on. According to postgres jdbc doc there is a property like

问题 We have been facing weird connection timeouts on one of our websites. Our environment is composed of an IIS 7 web server (running on Windows Server 2008 R2 Standard Edition) and an SQL Server 2008 database server. When debugging the website functionality that provokes the timeout, we notice that the connection itself takes milliseconds to complete, but the SqlCommand , which invokes a stored procedure on the database, hangs for several minutes during execution, then raises the timeout

问题 When I try to do the following code, the program hangs indefinitely. I don't know why and there seems to be other unanswered topics on the matter. Although, if the IP\website cannot be reached, then it works as intended. private void DoStuff() { string connectionString = "Data Source=www.google.com;Connection Timeout=5"; using (SqlConnection connection = new SqlConnection(connectionString)) { connection.Open(); //Hangs here indefinitely Console.WriteLine("Test"); } } For example, if I set the
