안녕하세요.
9.4 부터는 dynamic_shared_memory 라는 파라미터가 생긴거 같더라구요..
값이 posix, sysv, windows, mmap, none 이렇게 있는거 같은데
메뉴얼을 봐도 잘 이해가 가질 않습니다..
이해하기 쉽게 설명해주실분 계신가요..
Specifies the dynamic shared memory implementation that the server should use.
Possible values are posix (for POSIX shared memory allocated using shm_open),
sysv (for System V shared memory allocated via shmget),
windows (for Windows shared memory),
mmap (to simulate shared memory using memory-mapped files stored in the data directory),
and none (to disable this feature). Not all values are supported on all platforms; the first supported option is the default for that platform.
The use of the mmap option, which is not the default on any platform, is generally discouraged because the operating system may write modified pages back to disk repeatedly,
