A swap is an area of high-speed storage devices and an important part of the virtual memory system. Through the swap zone, we are no longer limited to limited physical memory space. Theoretically, we can infinitely expand the virtual memory system to run more programs and conduct more business transactions, make full use of hardware resources. The swap zone uses

use scenes for swap Swap has two main uses 1, when the system needs more memory space than physical memory, the kernel will use less memory inside the memory page swap out to the swap partition, to empty out the physical memory to the current should be used for fast running. 2, some applications started when the appli

Swap is a Swap partition in Linux, similar to Windows virtual memory. when the physical memory is insufficient, the system can put some programs that are not frequently used in the memory into Swap to solve the problem of insufficient physical memory. If the Swap space opened during system installation is too small, yo

I believe that the word "Swap" is certainly not unfamiliar, and even has the idea that this is not a simple element exchange. Indeed, swap exchange functions are not old words that are second only to hello word. However, the general algorithm is a little bit of charm in C ++ STL. This article not only elaborates on the STL generic algorithm swap, but also demonst

In fact, the adjustment of Swap partitions is crucial to the performance of Linux servers, especially Web servers. By adjusting the Swap partition, you can sometimes bypass the system performance bottleneck and reduce system

When installing Oracle 11g R2, the following message is displayed: swap size failed. The SIZE of SWAP space is smaller than the SIZE of SWAP space required by ORACLE. You do not want to re-partition the SWAP partition. Therefore, create a SWAP file and add 2 GB of file space
