Tags: Linux swap resizingI. Introduction:To improve read and write efficiency and speed, the Linux kernel caches files in memory, which is the cache memory. The Cache memory will not be released automatically even after your program has finished running. This will cause you to read and write files frequently in your Linux system, and you will find that there is less available physical memory. When the system's physical memory is not sufficient, it is

1, use the partition:When the OS is installed, a dedicated swap partition is created, and the size of the space must be planned in advance and mount automatically when the system is booted.This method can only be set when the OS is installed, and once the settings are changed very hard, unless the system is reinstalled.2. Use Swapfile: (or the entire free partition)Create a new temporary swapfile or an idle partition, set to

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

Swap partition, that is, Swap zone. How many people care about it except when installing Linux? 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
