MaxSharedMemorySize
|
This parameter sets the maximum total size of the shared memory area used by solidDB®.This parameter sets the maximum total size of the shared memory area used by solidDB®.
If the SMA server tries to allocate more, an “out of memory” error occurs. With value “0”, the maximum value is set automatically to be the size of the physical memory of the computer (platform specific).
Note The value set with the SharedMemoryAccess.MaxSharedMemorySize parameter takes precedence over the value set with any corresponding kernel parameter (for example, SHMALL in Linux environments). Thus, the value set with the SharedMemoryAccess.MaxSharedMemorySize parameter must not be higher than the value set with the corresponding kernel parameter.
If you set the SharedMemoryAccess.MaxSharedMemorySize parameter, do not use the Srv.ProcessMemoryLimit parameter.

▪user – access is granted only to the same user as the one that started the SMA server
▪group – access is granted to any user belonging to the same group as the one that started the SMA server
▪all – access is granted to all users
