However, since the refresh time of DNS domain name mapping relationships in various cities and even different regions of the world is often asynchronous or unknown, it usually takes 6 hours or even up to 72 hours for all domain name mapping relationships to take effect.
At the same time, due to various reasons such as time difference, routing, gateway, etc., during the time period when the website server data is migrated and the DNS servers in various places are not fully updated, some users often access the new IP address corresponding to the domain name, and some users access the new IP address corresponding to the domain name. It is an old IP address, which causes some users to be unable to open the website and use the website business normally

The present application provides a data migration processing method and device. The method may include: establishing a data communication link between the first database of the first address and the second database of the second address; setting the database connection of the business system of the second address to point to the first database , so that the business system at the second address accesses the data in the first database through the data communication link; synchronously copies the data in the first database to the second database; condition, set the database connection of the business system of the second address to point to the second database. By using various embodiments in this application, the integrity and uniqueness of the data accessed by the business system can be guaranteed during the entire data migration process, and the computer room and domain name can be switched without interruption of system services, reducing the risk of data migration.
Description
technical field [0001] The present application belongs to the field of computer data migration operations, and in particular relates to a data migration processing method and device. Background technique [0002] With the development and application of Internet technology, the number of visits to web servers has also increased dramatically. In order to ensure the normal operation of the business, especially in today's big data era, the security, stability, and reliability of server data storage and processing are particularly important. [0003] The data stored by the server may generally include system business data and business service data according to business functions, and these data may usually be stored in a data storage unit of the server, such as a database. However, with the development of business or due to factors such as design requirements, when the structure of the data storage unit of the server changes, upgrades or even merges, etc., the process of data mi...
