Label:4. Data chapter of SQL Server storage engine (4.1) Documents (0) Primary data file. MDF initial file size is at least 3MB, secondary data file. ndf initial size, the same log file at least 512KB; (1) SQL Server logically uses filegroups to manage files in batches (similar to Oracle's tablespace), a filegroup can contain multiple files, and when data is inserted, all files in the same filegroup grow proportionally. For example: There are two files in the filegroup, the initial size is 100M

I use PHP locally to export a database table of data into a CSV file, can be fully exported, the size can go to more than 800 K And I have the same PHP program on the site to export the same data table, can only export 8k multi-data. Try using Ini_set (' memory_limit ', ' 32M '); No, you can only export more than 8k, for a data table export can only export 8k mor

numeric value between 1 and 8,000. Storage size is the actual length of bytes of input data, not n bytes. The input data character length can be zero.2. Difference:1. From the storage mode, nvarchar is stored by character, while varchar is stored by byte;2. In terms of storage, varchar saves space because the storage size is the actual length of bytes, while nvarchar is a double-byte storage;3. In the use, if the storage contents are English characters and no other language symbols such as Chin

length of the field will be fixed in 2 bytes. If your business data has a maximum length of only 10, but defines a length of 256, each record will waste a byte to store the length. Oracle does not have such a problem, it will dynamically select the length identification based on the actual length of each record field. 3, the length of the field definition also has a greater impact on the index. Oracle has a certain limit on index length, 8i Official document description A single record index i

Numowners to 2-our configuration also has a 2.5GB of memory capacity. However, there is a problem: if we have a lot of 1K of data items, but only a small number of 200MB size of data items, which will result in uneven distribution of data. Some servers consume almost all of the memory heap because they store 200MB of data items, while other servers may not have the memory to use. Another problem is that if the current data item is larger than the available memory heap for a given single serve

at the application layer, Winsock copies the data sent by the application call send from the application's buffer to the Winsock kernel buffer. The Microsoft TCP stack uses a method similar to the Nagle algorithm to decide when to actually post data to the network. The default size of the kernel buffer is 8K, and you can change the size of the Winsock kernel buffer using the SO_SNDBUF option. If necessary, Winsock can buffer data larger than the S

The address space of a process, from the user's point of view, consists of a number of segments (segment), which can be divided into two types: Private segment, shared segment (GKFX). The CPU is also in accordance with the user's logic for memory management (fragmentation), Intel Pentium specifies that each segment has a maximum of 8K, each segment maximum 4G. A CPU pair should have a GDT (Global descriptor Table), which describes the shared segment i
