watchdog sys

A Overview Some important program must keep it running, and always care about its state------------can't let it deadlock. Of course, if a main program has a deadlock, it must be a design or programming error. The first thing we do is to get this bug out. But if the time is tight, this bug and "erratic", then, we still write a software "watchdog", temporarily should be urgent. Description of "Watchdog" req

/** Watchdog usage. * Author: serval li * Date: Jun 27th, 2012 **/# include CodeSave it first and use the watchdog implemented by softdog. C. Its kernel module is named softdog. Ko and is located under/lib/modules/$ kernelver/kernel/Drivers/watchdog.

Bug in STM32F4 Series MCU, window watchdog WWDG. 1. If it is possible to pre-feed the dog interrupt, then the following two points must be met (1) Before turning on the WWDG interrupt, the EWI flag bit in the SR register must be zeroed out, otherwise the watchdog will constantly reset (2) Add a small delay to the WWDG_IRQ, otherwise the watchdog will be const

Label: style ar use SP file data on log BS Because it is a software watchdog, his role can only be considered as a helper tool. However, its function should be meaningless. The implementation plan of this software is as follows: 1. Software form A module soft_wdt.ko runs in the kernel. 2. software startup Method Insmod soft_wdt.ko Dev =/dev/soft_wdt timeout = 5 log =/path/to/log.txt These parameters are: device files to be exposed to users,

The watchdog of recent projects has undergone three version numbers.First version number:With PS-EF, if the program hangs, it starts.Second version number:The program will not listen to the 7901port when it executes, so it is not easy to infer whether the machine is dead, but to infer if the port is listeningThird version number:When the 7901port is no longer listening, the original killall will be restarted first. Every time you output to a file, add

The Import Statement is imp sys/Sakura file = A. DMP, And the ORA-28009 connection to SYS shocould be as sysdba or sysoper error is returned. Solution: (1) set the parameter o7_dictionary_accessibility = true. This parameter defaults to true before 9i, but is false from 9i. If you do not change this parameter, use connect sys/password @ connectstring directly,

The system is set to 1024 by default, but this number is not enough for servers, especially large concurrency, so we need to change the actual situation to a larger and more reasonable value.Modify methodTemporary so
