Recently, my article has been very popular. I just want to summarize my knowledge from Marco Polo and send it to my blog. But I didn't expect that an article was first published nine times in the morning... If you really think my article is bad, please tell me the reason. Thank you very much. This week, Marco talked about Linux kernel compilation and Linux kernel modules, which are easy to understand. So I will share my learning achievements with you. First of all, this is just a simple compila

This is a creation in Article, where the information may have evolved or changed. A long time did not write a blog, recently really a bit depressed, the first level of their own limited, in the road to become Daniel struggling, ferocious struggle, followed by some people dissatisfied with certain attitudes, I think attitude is very important, good, spit groove is complete. SQL Server is required for the project. First Golang connect SQL Server with the official recommended package github.com/den

First, summaryThe following is a brief introduction to Windows proc Configuration development, this time we use the Linux platform to configure the Oracle proc OpenEnvironment (RedHat Linux 9 + Oracle 92).Oracle database Development (i). Windows configuration uses proc and Oracle database Development (II). Linux under Configuration using

Linux/proc meaning/proc is a virtual file system, that is, after the reboot, the modification will be re-initialized to provide process information, memory resources, hardware devices, kernel memory and other information such: NIC:/proc/sys/vm/ipv4/ip_forward: control ip Forwarding memory:/proc/sys/vm/drop_caches: inpu

The two differences between proc and lambda IN Ruby: proclamloud 1. In proc and lambda, the return keyword has different meanings.:In proc, return only indicates returning from this lambda.In lambda, return is not returned from proc, but from the scope that defines proc. C

The device under/proc/devices/is generated by the driver, which can generate a major for mknod as the parameter.The devices under/dev/are added by mknod. You can use this device name to access the driver.The following script, scull_load, is part of the scull distribution. The user of a driver that is distributed in the form of a module can invoke such a script from the system'sRC. LocalFile or call it manually whenever the module is needed.#! /Bin/shM

Implement a module that uses it to traverse the parent and task queues of the current process and output the traversed results to a proc file (the traversal can start from the current process, the parent process traverses to the initialization process, and the Traverse task queue can take advantage of the For_each_process macro).Here is the implementation part of my kernel module:/************************************************************* using ker

The file types of the Linux/unix system can be broadly categorized into three categories: normal files, directory files, and pseudo-files. Common pseudo-Files are special files, named pipes, and proc files, respectively.Pseudo-Files are not used to store data, so these files do not occupy disk space, although these files do exist in the directory tree, are part of the directory tree, and are also organized in the same way as license catalogs. The purp

When doing kernel-driven development, you can use the files under/proc to get the corresponding information for debugging.Most/proc files are read-only, but to demonstrate the integrity of the sample, a write method is provided.Method One: Create the proc file using Create_proc_entry (simple, but the write operation has a buffer overflow critical);Method Two: Use

The check_antp provided by nagios is too simple. In addition to the status statistics output, no parameters are provided. When faced with different application servers, alarm becomes a big problem.So I decided to write a check script myself. When running a script, it is different from the command operation, that is, to consider the efficiency issue. Running the netstat-ant command regularly on high-concurrency machines for statistics is obviously not suitable. You can retrieve data directly from

PROC simple use case -- connect ORACLE with VC Operating System: windows 7 Database Version: oracle 10g VS version: VS2010 There are many ways to connect to ORACLE. Here, we only use PROC as an example to explain how to connect to oracle. What's wrong with it? I hope you can learn more. 1. Install the Client Version corresponding to oracle 10 Gb.
