ObjectiveOn a SharePoint server that has been running for more than 2 years, it is strange to find that Sharepoint_config's database files are getting bigger and larger and have reached 90 gigabytes, shrinking by 20 gigabytes, but recovering to 90 gigabytes of size a week later.Because of insufficient disk space, there are only 200GB size, there are a number of l
this, go to the Control Panel, open the Programs and features window, and see a list of installed software. The size column shows that each application occupies an entire disk-something that is often dispersed across multiple disk locations in the total size of the program files. It is easy to see if an application takes up too much space and decides whether to uninstall it-or, if it is a modular installation, just remove some components. The complete installation package for Microsoft office a
the following information: Century, year, month, date, hour, minute, and second. Typically consumes 7 bytes of storage space. 3.2 Timestamp type This is a 7-byte or 12-byte fixed-width date/time data type. It differs from the date data type because timestamp can contain fractional seconds, and timestamp with fractional seconds can hold up to 9 digits to the right of the decimal point 3.3 TIMESTAMP with time zone type This is a variant of the timestamp type, which contains the value of the time

This function finds transactions that have not been spent on output. Since the transaction is stored in a chunk, it iterates through each chunk within the blockchain, checking every transaction inside. As of September 18, 2017, there are already 485,860 blocks in bitcoin, and the entire database requires more than three gigabytes of disk space.
to three minutes to transmit a MB file at a speed of KB (different from the wired network, because there is interference uncertainty in the wireless access network transmission, so the time cannot be accurate ). It takes at least 25 minutes to transfer a 1 GB file. For games with more than several gigabytes of video files, HD video files, or hard disk WLAN copies with dozens of gigabytes of hard drives, un
minutes to transfer a 1 GB file. For games with more than several gigabytes of video files, HD video files, or hard disk WLAN copies with dozens of gigabytes of hard drives, unless you are patient or impatient, so 802.11b, like a 10 m wired network, is not applicable to copying large-capacity Local Area Network files.

Because 802.11a is a mainstream non-market consumer, we will not introduce it
() specifies the size of the buffer to be described by the allocated MDL. If the length is less than 4 kb,Then the MDL mapped to it only describes a locked physical page;If the length is an integer multiple of 4 kb, the MDL mapped to it describes the corresponding number of physical pages (through the PFN array following the MDL)For Windows Server 2003, Windows XP, and Windows 2000,The maximum buffer length (in bytes) supported by this routine is:PAGE_SIZE * (65535-sizeof (MDL)/sizeof (ULONG_PT

Append the letter K or K to indicate kilobytes, m or m to indicate megabytes, g or G to indicate gigabytes.-xmx4g Specifies the maximum size (in bytes) of the memory allocation pool in bytes.

PHP backup MySQL database is a lot of personal webmaster site features, of course, if you want to back up a few gigabytes or larger database when the PHP backup method feel a little hard.

The hardware on the x86 platform supports two-level page tables. models above the Intel Pentium pro support PAE and three-level page tables, so that the maximum addressing capacity of the system is 36 bits, that is, 64 GB of memory. However, when a system process is running, it uses a virtual address. on a

Preventive Measures to Prevent DNS attacks
DNS amplification attacks on the Internet is growing rapidly. This attack is a large variety of data packets that can generate a large number of fake communications for a target. How many fake communications are there? Several gigabytes per second, enough to prevent anyone from accessing the Internet.
Similar to the old-fashioned "smurf attacks" atta
Computer storage unit bit (BIT) (binary digits): stores a bit of binary, that is, 0 or 1, the smallest storage unit. Byte: eight binary bits are one byte (B), the most common unit. That is, 1B (byte bytes) = 8 bit computer storage units are generally represented by B, kb, MB, GB, TB, Pb, EB, ZB, Yb, BB, the relationship between them is: 1 kb (kilobyte kilobytes) = 1024b, 1 MB (megabyte megabytes referred to as "megabytes") = 1024kb, 1 GB (gigabyte gigabytes
If you configure SQL Server to contain only several gigabytes (GB) of data and do not undertake heavy read or write operations, you do not need to pay too much attention to disk I/O topics, and balance SQL server I/O activities between hard disks for optimal performance. However, to create a large SQL Server database that contains hundreds of gigabytes of data and/or undertakes heavy read and/or write activ
