In C + +, it is well known that in a resource management class (such as a pointer to heap memory), you need to redefine the copy constructor, assignment operator, and destructor (Big Three), and you may need to define the move constructor and the move assignment operator under the new standard (big Five). But in fact, this rule can also have a small extension. In resource management classes, it is often necessary to redefine their own swap functions a

Understanding the pseudo-exchange, first of all we have to understand the concept of the exchange zone and the exchange mechanism of HP-UX! In the swap zone, when the system's physical memory is insufficient, the OS is used to temporarily store some data in the physical memory to free up more physical memory space! HP-UX swap mechanism: each time the system starts a process, it will reserve a certain am

The use of Digitalocean for a long time, a few days ago in the compilation of PHP when the process was killed situation, after my spit and communicate with others found that the reason for the memory exhaustion. In fact, because the MySQL process at that time consumed a lot of memory, and then feel the need to manually add swap (swap partition), so as not to compile any later when the process is K.On Linux

Install Oracle to change swap space size 1. Check the current partition: www.2cto.com [root @ localhost] # free-m 2. Increase the swap partition file and size, if you want to increase the swap partition size by 2 GB, the command is written as follows, where count is equal to the expected block size. [Root @ localhost] # dd if =/dev/zero of =/home/

The swap partition is a Linux swap partition. The swap partition actually exists on the disk, but the Linux system can use it as memory, and swapping partitions can exchange data with real memory when the physical real memory is low. To put it simply is to take a space out of the disk as a storage area for memory. Although the disk is used as memory, the speed is
