In this issue, the editor will bring you about the meaning of / dev/shm in the Linux system catalog. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

There is a directory in the Linux file system: / dev/shm, where dev is an abbreviation for device (device) and shm is shared memory.

Think of / dev/shm as the entrance to system memory, as a physical storage device, and the directory maps not disk, but memory.

The file system mounted on / dev/shm is tmpfs,temp file system, which means temporary file system.

By default, the capacity of / dev/shm under linux is half the size of memory. But it doesn't really take up this piece of memory, and if there are no files under / dev/shm/, it actually takes up 0 bytes of memory.

ORACLE's memory_target takes advantage of / dev/shm. The typical error associated with it is ORA-00805.

The above is the meaning of / dev/shm in the Linux system directory shared by Xiaobian. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
