Shmmax to the 32-bit number limit), which is 4G. So in general, 1-4g physical memory, you can directly set the Shmmax to the maximum physical memory, then the SGA must be in a shared memory segment, 32Bit Linux system physical memory greater than 4G set to 4G. In summary, general settings Shmmax >=SGA (32Bit system support to 1.7G above SGA needs attention). If the Linux operating system is 64Bit, Shmmax is set to be greater than sga_max_size.

. NTFS uses smaller clusters to manage disk space more efficiently. In the case of the FAT32 file system of Win 2000, the size of the partition at 2GB~8GB is 4KB, the size of the cluster is 8KB when 8GB~16GB, and the cluster size is 16KB when the partition size is 16GB~32GB. The NTFS file system of Win 2000, when the size of the partition below 2GB, the size of the cluster is smaller than the corresponding

Mainstream preferred: Reitna MacBook Pro 13 The Retina MacBook Pro Series is your best option if you're going to buy a computer for everyday learning, or if you often need to deal with heavy work like video or a lot of pictures. Among them, the Retina MacBook Pro Series has 13 and 152 sizes, their shape is not small, 13 inches in the portability of more advantages, suitable for white-collar

2015 MacBook Pro 15 How much less money? The Apple 2015 MacBook Pro 15 notebook has a low and a high version of two versions, both CPU and graphics card are different, and thus the price is not the same. The 2015 MacBook Pro 15 low version is equipped with the latest Intel Core i7 processor, 16GB memory, 256GB SSD, and Intel Iris Pro Core graphics (not paired with a separate video card) for a price of 14288 yuan; The 2015 MacBook Pro 15 high edition

IPhone 6 has made a big upgrade on the screen, but Apple still has room for improvement in this area. Given that Apple has a larger screen of IPhone6 Plus, users will be watching more video on it, so the iphone 7 screen will be bigger and more high-definition. Later, the movie is on the iphone 7! 　　 5, better battery endurance, support the replacement of batteries The iphone 6 may have more battery power than previous generations of iphones, but users have always want

this AMD graphics card is that it is far less energy than the latest Maxwell architecture GPU, it can be in the MacBook Pro full play we are not sure. To be sure, this GPU has improved performance compared to the pre-upgraded GT 750M, and users who desperately need an apple laptop with a more robust GPU performance can opt for a highly-equipped MacBook Pro 15 with a standalone video card. 　Memory 8GB up Storage 256GB Best We all know that Apple notebook hardware upgradeable options are very

huge array and then accesses the data in bytes, leaving the operating system (OS) to handle the rest. This is the design decision that allows MongoDB to run in RAM without any modification. Implementation Methods All this is done by using a special type of file system called Tmpfs . It looks like a regular file system (FS) in Linux, except it's completely in RAM (unless it's larger than RAM, and it can be swap at this point, which is useful.) ）。 My server has 32GB of RAM, let's create a

1. Open "Start" menu, click "Run" button 2. Enter "CMD" in the pop-up window, then confirm or press ENTER. 3. Enter "Wmicmemphysical get Maxcapacity" in the command window and hit enter. 4, then the computer will give a string in kilobytes units of the number. We'll convert this number to our common GB units. The conversion method is: "Obtained number/(divided by) 1024/(divided by) 1024" Figure: My computer gets the number of 16777216K bytes, then I divide by 1024 and divided by 1024,

got 5202 points, easily exceeding the average score of 4433. However, this result is still downwind compared to MSI GT70 (7352 points) and Alienware 17 (5903 points) with Nvidia GeForce 780M graphics. In the test "World of Warcraft" game, g750jx-db71 maximum support frame number of 102fps, also exceed the average of 100fps, but still with Alienware 17 103fps and MSI GT70 105fps compared to some low. Also in the "Biochemistry: Infinite" test, g750jx-db71 in 1080p resolution of the results

system failure event occurs. 3. NTFS supports compression of partitions, folders, and files. Any windows-based application that reads and writes compressed files on an NTFS partition does not need to be uncompressed by other programs, and the files are automatically decompressed when the file is read, and the files are automatically compressed when the file is closed or saved. 4. NTFS uses smaller clusters to manage disk space more efficiently. In the case of the FAT32 file system of Win 2000

Many children's shoes want to give their old computer installation Win8 system to try to know whether the hardware configuration to meet the requirements, in fact, the minimum configuration of WIN8 system requirements is not very high, if your computer to meet the configuration requirements of the following diagram, installation Win8 system without pressure.

The Linux shared memory page size is 4KB and the shared memory segment is an integer multiple of the size of the shared memory page. The maximum size of a shared memory segment is 16G, then the number of shared memory pages is 16gb/4kb=16777216kb/4kb=4194304 (page), that is, 64Bit system under

Asus always attaches great importance to the audio-visual entertainment notebook market, Asus N Series notebook as the first to enter this part of the market products, has been deeply loved by consumers. A few years due to similar technology, product shape similar, the homogeneity of the brand between the serious, the brand began to open ideas to strive for product differentiation, especially in the mid-range products. ASUS has also undergone this transformation, innovating N-Series notebooks to
