Problems solved by technology

[0002] At present, due to the continuous upgrading of database technology, it is necessary to upgrade the old database (that is, migrate the data to the new database), but in practice, it is found that when using the new database, errors may occur in operations such as data addition, deletion, query, and modification , these errors are likely to cause service interruption, resulting in system unavailability

Embodiment approach

[0078] As an optional implementation, the method also includes:

[0079] If the target database is abnormal after performing the first operation, generate abnormality warning information;

[0080] Send the abnormality alarm information to the abnormality management device.

[0081] In this optional implementation manner, if the target database is abnormal after performing the first operation, abnormal alarm information may be generated, and the abnormal alarm information may be sent to the abnormal management device to remind relevant personnel to Troubleshoot the above target database.

[0082] S17. Determine the performance index of the target database.

[0083] Wherein, the performance index may be the remaining capacity of the target database, the query speed of the target database, the response time of the corresponding operation of the target database, and the like.

[0084] S18. If the performance index of the target database is greater than a preset performance inde...

Abstract

The data migration method comprises the steps of establishing connection with a to-be-migrated database, and determining operation activity of the to-be-migrated database at each time; determining target time according to the operation activity; at the target time, forbidding first operation on the to-be-migrated database; establishing a connection with a target database, and migrating the data inthe to-be-migrated database to the target database, the target database being forbidden to perform a second operation; when an instruction for carrying out a first operation on the migration databaseis received, carrying out the first operation on the target database; if the target database is not abnormal after the first operation, determining a performance index of the target database; and ifthe performance index of the target database is greater than a preset performance index threshold, determining that data migration is completed. The invention further provides a data migration device,a server and a storage medium. According to the invention, the stability of data migration can be improved to ensure the availability of the system.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data migration method, device, server and storage medium. Background technique [0002] At present, due to the continuous upgrading of database technology, it is necessary to upgrade the old database (that is, migrate the data to the new database), but in practice, it is found that when using the new database, errors may occur in operations such as data addition, deletion, query, and modification , these errors are likely to cause service interruption, resulting in system unavailability. [0003] Therefore, how to improve the stability of data migration to ensure the availability of the system is a technical problem that needs to be solved urgently. Contents of the invention [0004] In view of the above, it is necessary to provide a data migration method, device, server and storage medium, which can improve the stability of data migration to ensure the avail...
