However, Wei just said that the DDR4 version of ECC So-dimm, VLP RDIMM, LRDIMM and other types are also being developed, will soon be introduced.
These memory are used by servers and workstations, and Wei Gang said they have been working closely with Intel, and its DDR4 me

Configuration of swap on Oracle serverOn Oracle servers, setting the appropriate swap size can improve Oracle's performance, and for Oracle 11g, the physical memory on the Oracle server and the swap size to be set are as follows:If the physical memory is less than or equal to 2GB, then swap should be 1.5 times times the physical memory;If the physical presence between 2GB to 16GB, then the swap size is best equal to physical memory;If the physical mem
of the shared memory segment is an integer multiple of the shared memory page size. The maximum size of a shared memory segment is 16G, then the number of shared memory pages is 16gb/4kb=16777216kb/4kb=4194304 (page), which is 64Bit system 16GB physical memory, set Kernel.shmall = 4194304 to meet the requirements (almost twice times the original setting 2097152). At this time can adjust the Shmmax paramete
wal_keep_segments heavily. The idea of this postgresql.conf setup is to keep master in more Xlog files than is theoretically needed. If you set the variable to 1000, it means that master will keep the xlog above 16GB. In other words, your slave can disappear 16GB compared to normal (convert to master). This greatly increases the slave's advantage of joining a cluster without having to fully synchronize its

The size of the Linux Shared memory page is 4KB, and the size of the shared memory segment is an integer multiple of the shared memory page size. The maximum size of a shared memory segment is 16G, then the number of shared memory pages is 16gb/4k

that you have a great app that can do something different, maybe be able to go online to a social network, work with PIM data, or provide a new way to play. Then you have a way to make your app stand out from thousands of apps. But then there will be countless developers who develop clones to pull down the price of your app and compete with you. The Android store is almost a lawless society. If we do not solve this problem and let developers face unfair competition, how many developers are will
