Customer site, telecommunications-related 7*24h business, a province database two node alert constantly produce ORA-7445 error, and throw trace dump file, TRC file. One node alert does not have 7445 related errors, only the core file is generated. CRS, syslog and other logs no obvious alarm. Does not cause a restart and does not cause a business impact. Just constantly error, due to Oracle directory space 40G, in order to prevent the database instance rammer, the customer decided to resolve the

The modulo is 1000 0000 (0 Less Than the complement code)All the bits of the complement code can be added, and the modulo is 10000 0000 (the highest bit is not a sign bit, And the complement code is obtained by subtracting the absolute value of the negative number)5.

From the time we touched Java, we were told that the underlying type, byte, is a byte, which occupies 8 bits, and the range represented is -128~127. So why is this range??? Let's take a look at the basics of computers: 1. In the computer internal data storage and operation are used binary;2. The data in the computer is divided into signed number and unsigned number, for the signed number, the computer specifies the highest bit to represent th

Why is the range of 8-Bit Signed numbers "-128-+ 127 "? (Reposted and supplemented) 11:22:57 | category:It | Tag:| Large font size, medium/small subscription This is a problem that has puzzled me for several years. It has left me extremely dissatisfied with the current textbooks and teachers. Since I started to touch my computer N years ago, in almost every C ++ textbook, the 8-Bit Signed value range is-128

minus 1 is 01111111, and then 10000000 is reversed.Because the complement of a negative number is reversed by its absolute value, that is, 10000000 is the absolute value of the minimum negative number, and 10000000 of the decimal representation is 128, so the minimum negative number is-1284, it can be concluded that the value range of byte is 128 to +1275, Description: The calculation method of each type o

When interacting with Java programs, the Java side uses AES 128-bit fill mode: Aes/cbc/pkcs5padding encryption method, the corresponding AES-128-CBC encryption method in the Nodejs can be corresponding, because there is the use of vector (iv), So the Createcipheriv method should be used in Nodejs, not createcipher.In this kind of encryption and decryption calculation, the most important thing to pay attenti

Some Linux (Chinese version) Installation manuals often show that the swap space cannot exceed 128 MB. Why is there such a saying? Before explaining the history of the number "M", I would like to give a question: there is no m limit at all! The current limit is 2 GB! Swap space is paging. The size of each page is the same as that of the Memory Page, facilitating data exchange between swap space and memory. In the earlier version of Linux, when impleme
