Abstract

The invention provides a database upgrading method and device. The database upgrading method comprises the steps that data of old data tables of an old database are received, the received data of the old data tables are processed, the processed data are obtained, the processed data are stored in new data tables of a new database, if it is judged that the difference between the data size of the new database and the data size of the old database is smaller than a set value, connection between a service system and the old database is switched to connection between the service system and the new database, and therefore it is guaranteed that the service system is not interrupted, and the data in the oil database are not lost.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a database upgrade method and device. Background technique [0002] With the rapid development of the mobile Internet, people can use various services provided by the Internet anytime and anywhere, so the continuity and stability of Internet services are particularly important. Upgrading Internet services is bound to face database upgrades. How to ensure that business is not interrupted during database upgrades and ensure that the upgraded new database is consistent with the old database has become the key to improving Internet services. [0003] At present, most of the database upgrades are carried out in the following ways: each data table in the old database is upgraded in a circular manner, the upgraded data tables form a new database, and finally the business system is switched from the connection with the old database to the new database. Connection. For example...
