The swap space on Solaris is similar to the virtual memory on windows. It is used to temporarily cache the data in the memory on the hard disk and load the data into the memory as needed.The swap space is set when the system is installed. It is specially divided into a partition (equivalent to a partition) in the disk for the swap zone. however, in actual use,

Using the dd command to temporarily add swap partitions sometimes causes insufficient memory. you can use the method provided in this article to temporarily add swap partitions.

CentOS and Redhat Adjust the size of the Exchange partition is the same way, I have done;The first step, you want to make sure that there is enough space on your disk to do swap partition, swap partition really find an empty space on the disk to simulate into memory, when the memory is not enough, put some unimportant content into the swap partition, so, execute

Add Swap to CentOS DigitalOcean has been used for a long time. A process was killed when PHP was compiled a few days ago. After I spoke with others, I found that the memory was exhausted. In fact, it was because the MySQL process at that time consumed a lot of memory, and later felt it was necessary to manually add Swap (Swap partition), so as to avoid the proce

1. swap OverviewSwap partition, that is, Swap zone. The role of Swap space can be simply described as: when the physical memory of the system is insufficient, a part of the physical memory needs to be released, for the currently running program. The released space may come from some programs that haven't been operated for a long time. The released space is tempor

Under Linux You can create two types of swap space, one swap partition and one swap file. The former is suitable for free partition can be used, the latter is suitable for the non-empty hard disk partition, the hard disk space has been allocated. For example: When installing Redhat, you can divide the hard disk space by default, the size of the

When compiling the Dlib library on my Raspberry Pi pi3, I found that the compilation failed because of insufficient memory. The Raspberry Pi is 1G memory, swap only 50M, so the swap is increased to 500M, compiled through. Here's how to set it up: Using the free command with the M parameter to see the swap file size, the official recommendation is that when RA

Swap area (swap) is an area that exists on a high speed storage device and is an important part of a virtual memory system. Through the swap area, we are no longer limited to the limited physical memory space, theoretically can expand the virtual memory system, so as to run more programs, more business transactions, more fully play hardware resources.
