method, this scenario reads the configuration file when the server is started, and the OLC-oriented modifications are immediately available and do not require the service to be restarted. The OLC system validates and executes modifications using the standard LDAP method. Because of this, regular management of LDAP is often seamless because it uses the same knowledge, skills, and tools as the DIT data. However, for friends who have just contacted LDAP, it is often difficult to get started becaus

HDFs block of data Disk data block is the smallest unit of data read/write for disk, typically 512 bytes, There are also data blocks in the HDFs, and the default is 64MB. So the large files on the HDFs are divided into many chunk. Files that are small (less than 64MB) on HDFs will not occupy the entire block of space. The reason for the large set of HDFS data blocks is to reduce the addressing overhead, and the data backup is also in blocks. Use the Hadoop fsck/-files-blocks command to check

Use of the command will undoubtedly improve the efficiency of system management. In addition, the use of hidden parameters in the command can be implemented in some graphics interface can not be easily implemented tasks. A significant number of command tools have been integrated into Windows 7, and these tools are powerful weapons for our system management. The following is a list of several command-line tools in Windows 7 that you can use to achieve

In Coos, the task has four states, namely: Ready state, running state, waiting state, dormant state. Why do you want to separate the state? The goal is to give the CPU to more needed tasks, for example, you open a browser and open a game (need full screen), so when you play the game, let the browser this task hangs, to enter the waiting state. Then the entire CPU is serving the game, without the advent of the card. The same principle, can also be

For example, as soon as a user enters a command, the shell process creates a new process, and the new process runs another copy of the shell and executes the command entered by the user. The Linux system is used to create a new process through fork/vfork system tuning. This article describes how to use the Fork/vfork system tune to create a new proc

In the previous Post, we have read several common synchronization types. This article will introduce the implementation of declarative synchronization and the sharing of Set-type data, first, let's look at the implementation of declarative synchronization. Declarative SynchronizationWe can identify a class by using the Synchronization feature, so that all fields and methods of a type can be synchronized. When Synchronization is used, we need to inherit the class of our target Synchronization fro

2.6 scheduled tasks In Linux, there are two types of scheduled tasks: one is to execute only one at scheduled task, and the other is to execute cron scheduled tasks cyclically. 2.6.1 at one-time scheduled task Before using at to specify a one-time scheduled task, make sure that the atd service is enabled. Otherwise, the scheduled task is not executed. Use Servic
