Now the policy of the Linux kernel is to use as much of the memory as it can for something useful. First priority obviously goes to os / application code. All the rest is used for buffer/cache (more on that here:http://stackoverflow.com/questions/6345020/linux-memory-buffer-vs-cache)....
In 9.3, PostgreSQL has switched from using SysV shared memory to using Posix shared memory and mmap for memory management. This allows easier installation and configuration of PostgreSQL, and means that except in usual cases, system parameters such as SHMMAX and SHMALL no longer need to be adjust...

关于权限我们已经在《Memory Window》一文中有过介绍,MR和MW的权限是一样的,因此我们不再重复介绍了; 防止换页(Pin页) 关于Pin页我们已经在《Queue Buffer》一文中讲解过了,Pin是为了防止虚拟地址和物理地址的映射关系发生改变,否则会导致RDMA网卡在翻译VA时获得错误的PA,进而产生错误访问和安全隐患; ...
