Processing method and apparatus for data migration

Abstract

The invention provides a processing method and apparatus for data migration. The method comprises the following steps: creating a data communication link between a first database for a first address and a second database for a second address; setting the connection of the database of the second address's business system as indicating the first database so that the second address's business system could access the data in the first database through the data communication link; synchronously copying the data in the first database to the second database; and setting the connection of database of the second address's business system as indicating the second database when the preset switching condition is fulfilled. According to the various embodiments of the invention, it is possible to ensure the integrity and uniqueness of data that a business system accesses in the entire data migration process so as to accomplish the switching between machine rooms and domain names without the interruption of system service, therefore, 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...

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
