the relationship between the server parameter file (SPFILE) of Oracle 11g parameter file and instance startup
what is a server parameter file
a server parameter file can be considered as an initialization parameter file, which is stored in the system running Oracle database server. It is designed as a server initialization parameter file, which is stored in the server parameter file The initialization parameters in the file are permanent. When the instance is running, any changes to the parameters are still valid after the database is restarted. This eliminates the need to manually modify the initialization parameters in order to make the change of alter system statement permanent. It also provides the basis for automatically adjusting the database server.
a server parameter file is created by using create sp The server parameter file is a binary file and cannot be modified by using a text editor. Oracle database provides other interfaces to view and modify the parameters in the server parameter file.
note: Although you can use a text editor to open a binary server You can't restart the instance. If the instance is running, it will stop running
1. What is blockchain
in short, blockchain is a super ledger, which is used to record public data and has the characteristics of non repudiation and non tampering
for example, a borrows 10000 yuan from B. the traditional way is that both parties write IOU or bank transfer records, and both parties have records of borrowing and repaying money. This IOU or bank transfer record is a "center". When there is a dispute, the records of the "center" shall prevail. If the "center" makes mistakes and the records disappear, the dispute will be difficult to solve
in the blockchain network, each computer is an account book. As long as a borrows 10000 yuan from B in the computer, there are data records in the computers of a and B, and there are also records in thousands of other computers. The account book is updated in real time, and any transaction in the blockchain network will be recorded in the personal account book. There is no need for the participation of third parties such as banks or so-called "authoritative institutions" or "certification bodies"
How doesblockchain technology enable digital economy
however, although blockchain technology is so great and revolutionary, blockchain itself is still limited to an ideal and ideological trend in many fields, and there are not many real applications. From the domestic and foreign point of view, the more mature application is mainly in the financial field such as digital currency
. In the field of cross-border remittance, ant gold clothing uses block chain technology to provide low rate and high-speed cross-border remittance services to China, Hongkong, Philippines, Pakistan and Malaysia. p>
in the clearing and settlement field, the HKEx plans to use the blockchain settlement system to simplify the northbound trading process of mainland stocks under interconnection, so as to facilitate European and American investors to invest in a shares
The real breakthrough and implementation ofblockchain technology application will take time. So, in addition to the financial field, what other scenarios may blockchain technology be applied to in the future
1) digital identity. Now when we travel far away or go out to do business, we always have to provide various certificates, such as birth certificate, ID card, degree certificate, real estate certificate, marriage certificate, etc.. With blockchain, we don't have to worry about the problem that we can't find certificates to prove that "I am me"
2) medical and health care. For example, a person's case can be managed by a blockchain. For example, when a doctor sees a doctor, an indivial can be authorized by the doctor to see the case, but the doctor can't even tell who it is
3) public management. The main applications are food safety traceability and drug traceability
(4) intellectual property protection. If a professional's own works are put on the blockchain, and someone uses his works, he will know immediately. The corresponding royalty will also be automatically paid to the creator. Blockchain technology not only protects right, but also helps creators sell their works to consumers more directly without the assistance of distribution companies5) supply chain management. In the supply chain management system based on blockchain, it is very easy to record, store and trace the source, because the enterprise information can obtain the proct information through the built-in sensors and RFID tags. The process of procts from origin to destination can be traced by blockchain. Moreover, this kind of accurate traceability method can be used to detect the defects in the supply chain
in addition, it is also the application scenario of blockchain technology in many fields such as trade and charity
