1, modify the user process can open the number of files limitOn a Linux platform, regardless of whether you write a client or a service-side program, the highest concurrency is limited by the number of files that can be opened by the system at the same time as the user's single process (because the system creates a socket handle for each TCP connection) for high concurrent TCP connection processing. Each socket handle is also a file handle. You can use the Ulimit command to view the limit on the

SQL Server 2005 allows configuration instructions for remote connections When you try to connect to a Microsoft SQL Server 2005 instance from a remote computer, you may receive an error message. This problem may occur when you connect to SQL Server using any program. For example, when you use the SQLCMD utility to connect to SQL Server, you receive the following error message: Sqlcmd: Error: Microsoft SQL Native Client: An error occurred while estab

Network programmingIn a TCP application, the server listens to a fixed port beforehand, the client initiates the connection, and a TCP connection is established after a three-way handshake. So what is the maximum number of concurrent TCP connections for a single machine?How to identify a TCP connectionBefore determining the maximum number of connections, let's look at how the system identifies a TCP connect

The following articles mainly introduce three useful methods for correctly modifying the maximum number of MySQL connections. We all know that after the MySQL database is installed, the default MySQL database has a maximum number of connections of 100, generally, the number of connections to a forum or website with a slightly larger traffic is far from enough. Th

The timeout has reached. The timeout time has reached, but the connection has not been obtained from the pool. This may occur because all pool connections are in use and the maximum pool size is reached. Solution1. Close the unclosed connection in the code.2. Expand the sharing pool as follows:The solution is to modify the connection life of the Connection Pool, because the default value is 60 seconds, that is, the time when the connection can be save

The number of concurrent connections refers to the ability of a firewall or proxy server to handle its business information flow, is the maximum number of point-to-point connections that a firewall can handle at the same time, reflecting the ability of the firewall device to access and link state tracking for multiple connections, and the size of this parameter d

of files available for the client socket connection is only about 1024-10 = 1014 or so. In other words, Linux-based communication programs allow up to 1014 simultaneous TCP connections by default.For a communication handler that wants to support a higher number of TCP concurrent connections, you must modify the soft limit (soft limit) and the hard limit (hardlimit) of the number of files that Linux has ope

Push" technology based on Pure browser is starting to get more attention, Alex Russell (Project Lead of Dojo Toolkit) calls this "server push" technology that is based on HTTP long connections and does not need to install plugins in the browser. There have been some mature Comet applications and various open source frameworks, and some WEB servers such as Jetty are also making a lot of improvements to support a large number of concurrent long

Many users have a vague understanding of the concept of the number of connections, which is described as follows: 1. The visitor must establish a connection with the site through the TCP protocol to access the site. This connection exists when reading information from the server. When the read ends, it is generally automatically closed. Therefore, when a page is completely displayed on the client's display, the connection used may have been disabl
