Use C # to create a scheduled Task (How to create a Task scheduse use C #), This article describes how to use C # To create a windows scheduled task. Requirement: Run multiple background programs (winfrom, wpf, console, and so on) in an indefinite period of time to update data. Problem: Why do we need to use a scheduled task instead of simply using a timer in

disk reads and writes, resulting in excessive IO usage. Therefore, the number of concurrent connections cannot meet the requirements. Clear the log file.Considering that similar problems may occur in the future (of course, in reality, it is impossible to achieve the test results in a few days), we hope to use the method of regularly deleting logs. Here we take into account the need to use linux scheduled tasks, also known as routine commands.1. cycli

Today, in a project, I encountered a fault: The system is conducting a stress test on the Weblogic-based OA system, and the number of concurrent connections is very small (much lower than the normal number ), the system uses the red-flag DC 4.1 for anteng 2 and apache for web Service forwarding.After a series of checks, it was found that the previous two consecutive days of stress testing, resulting in 20 GB of space in the/var directory where logs are placed; as a result, new logs need to const

A common use in VPS is to perform tasks regularly, and to perform tasks regularly can reduce human workload and improve efficiency. The timing task of a Linux system is controlled by a cron (Crond) system service. The Linux system already has a lot of planned work on it, so this system service is started by default. In addition, because the user can set the scheduled task themselves, the Linux system also provides the user Control Scheduling task comm

Starting with Spring3.1, the implementation of the scheduled task in spring becomes unusually simple. The first step is to turn on support for the scheduled task by configuring the class annotation @enablescheduling, and then annotate the @scheduled declaration on the method to perform the scheduled task. This is a
