LOG4J is an Apache open source project that uses log4j to control log information delivery destinations for consoles, files, databases, GUI components, even socket servers, NT Event loggers, UNIX Syslog daemons, and more ; Can control the information content and information output format of each log; By defining the level of each log information, we are able to control the log generation process more carefully, even if you do not need to modify the bu

Description: This program demonstrates how to use Log4net to record program log information. Log4net is a feature-famous open source logging component. The log4net makes it easy to log information to files, consoles, Windows event logs, and databases (including MS SQL Server, Access, Oracle9i,oracle8i,db2,sqlite). And we can also record the level of log control to be recorded, log categories include: FATAL (fatal error), error (general error), WARN (w

It provides developers with features such as modular and plug-in, service-oriented architecture, and module extension support for consoles,WinForm,asp,WPF, and Windows services

system type is automatically detected. If the root file system mount fails, for example because you forgot to include related file system drivers in the core, the core will fail and the system stops (there is nothing left to do at this time). The root file system is usually read-only mount (this can be used in the same way as the location). This allows the file system to be checked on Mount time; It is not a good idea to check for a read-write file system that has been mount. The core then laun

Linux terminal and Terminal login process Introduction The shell is the system's user interface, which provides the interface that the user interacts with the kernel. It receives the command entered by the user and sends it to the kernel for execution, and then displays the results to the user. Linux Terminal usage Basics: Monitors and keyboards are called terminals because they can control the system, which is called the console (physical console). If the software is used in a computer to ach

process identification number. For example, in the top command, we see that the system runs many processes, and sometimes it is necessary to abort certain processes using kill to improve system resources. When explaining the installation and landing commands, it was mentioned that the function of multiple virtual consoles of a system is to switch to other virtual consoles to work off the program when a pro

logon week, month, day, time, and the Virtual Console used.4. Application TipsLinux is a true multi-user operating system that allows multiple users to log in at the same time, allowing one user to log in multiple times. This is because Linux, like many versions of UNIX, provides access to the Virtual console, allowing users to log in multiple times at the same time from the console (the system's console is a monitor and keyboard that is directly connected to the system). Each virtual Console c

Because the system defines 6 virtual consoles by default,So X is the 7th one. In fact, many people do not normally need so many virtual
