Exposure to computers all day, inevitably with a variety of measurement units to deal with, especially data, but you know bit, Byte, KB, GB, TB and so on all means how much data? Have you heard of EB, ZB, YB?
Bit (bit) is the initials of binary digit, the unit that measures information, and the smallest unit that represents the amount of content, only 0 or 12 binary states. 8 bits make up a byte (byte), can hold an English character, and a Chinese ch
In a file-processing system, it is easy to get the size out of some system's own method, the problem is that the size is often just a byte B.If you want to convert this byte number to a KB, MB, GB final rendering to the user, it involves the arithmetic operation of dividing and taking the remainder.Here's how:public static String getprintsize (long size) {///If the number of bytes is less than 1024, it is directly in B, otherwise except for 1024, the

Today, I saw a friend using a 168 network hard disk on the red link BBS. Actually, the 168 network hard disk is really good, but it is too inconvenient: 1. The total space is only 80 Mb (free of charge)
2. Only files smaller than five MB can be uploaded

Previously we introduced:Oracle 10 Gb Memory StructureIn this section, we will introduce the 10 Gb memory structure of Oracle.Sharing poolNext, let's take a look at this part.
The third component of SGA is the shared pool. The shared pool is the memory area for syntax analysis, compilation, and execution of SQL, pl, and SQL programs. The shared pool includes the library cache of the library Buffer and the D
What we want to introduce today is the operating language (DML) for Oracle to use FIRALL to process some non-consecutive arrays and execute relevant data in PL/SQL loops) in fact, it is a very time-consuming task, because every cycle needs to be switched from the PL/SQL engine to the SQL engine. Applying FORALL is a better way to submit a set of temporary values to SQL statements at a time.
Before Oracle 10 Gb, The FORALL statement syntax can only pro
Php obtains the file size and converts the file size to gb, mb, and kb. this code uses the php program to obtain the file size and displays the file size as gb, mb, the code of kb code is very intelligent. the code is as follows:

If ($ filesize> = 1073741824 ){
$ Filesize = round ($ filesize/1073741824*100)/100. 'GB ';

1. Get the file size
1. Use the stat function to obtain the file size.
Let's take a look at the struct structure. The file size is defined as follows:
# Ifndef _ use_file_offset64_ Off_t st_size;/* size of file, in bytes .*/# Else_ Off64_t st_size;/* size of file, in bytes .*/# Endif
Generally, we use _ off_t, that is, long int (4 bytes,-2147438648 ~ + 2141438647), while _ off64_t is long int (8 bytes,-9223372036854775808 ~ + 9223372036854775807 ).

Oracle uses Incomplete Database-level recovery to solve the logical errors caused by data loss or human error before 10 Gb. After 10 Gb, RMAN introduces a new feature called "tablespace point-in-time recovery", TSPITR for short, which can actually achieve Incomplete recovery at the tablespace level, of course we know that after 10 Gb, the flashback feature can al
If you want to restore a database on a colleague's machine to your own machine, the DMP file provided by the colleague cannot be used.
