ubuntu memcached Installation and Configuration
It is divided into two processes: Memcache server-side installation and memcached client installation.
The so-called server-side installation is to install Memcache on the server (generally Linux system) to implement data storage
The so-called client installation refers to PHP (or other programs, memcache and other good API interface) to use the server-side memcache provided functions, PHP needs to add extensions.
1) Install Memcache server

One day Vasya was sitting on a not so interesting Maths lesson and making an origami from a rectangularAMm? ×?BMm sheet of paper (A?>?B). Usually the first step in making an origami is making a square piece of paper from the rectangular sheet by folding the sheet along the bisector of the right angle, and cutting the excess part.
After making a paper ship from the square piece, Vasya looked

Chapter 1 Why dynamic link library (DLL)
When you mention a DLL, you will not be unfamiliar. in Windows, there are a large number of files suffixed with DLL, which are an important guarantee to ensure the normal operation and maintenance of Windows. (For example, the Win95 System directory contains more than 500 DLL files .) In fact, DLL is a special executable file. It is special because it generally cannot be directly run and can be used only when the host Program, such as *. EXE or dynamic ca

Memcachesize sets the maximum amount of memory that IIS will use for its File Cache. if IIS does not need this much memory, it will be left for other applications to use. by default, IIS uses 50 percent of the available memory. the valid range is from 0 megabytes to the total amount of physical memory available in megabytes.
Objectcachettl sets the length of time (in milliseconds) that objects are held in

Master table: records the metadata of the database object in dumpfile. When the expdp ends, it is written to dumpfile and read from impdp, so that the content in dumpfile can be known.
Worker processes: executes the Export and Import tasks. Multiple worker processes are automatically created and executed in PARALLEL according to the actual situation, but cannot exceed the number defined by the PARALLEL parameter.

The system still has several hundred MB of memory, which is enough. This issue should be considered in wince.
