Abstract

The invention relates to the technical field of database synchronization, and discloses a heterogeneous database synchronization data consistency verification method and device. The verification method comprises the following steps of establishing a submission transaction table in a target end database, and recording synchronized source library transaction information in the submission transactiontable; capturing and analyzing a source end transaction log of a source end database; capturing and analyzing a target end transaction log of the target end database; sending the target end transaction log to a source end data synchronization verification service; and comparing the source end transaction log with the target end transaction log according to the synchronized source library transaction information, and verifying the consistency of the synchronization data. When consistency verification is carried out on the synchronous data of the heterogeneous database, normal work of the source end database cannot be influenced, and stability of the real-time data synchronization process cannot be influenced.

Description

technical field [0001] The invention relates to the technical field of database synchronization, in particular to a method and device for checking the consistency of synchronous data in heterogeneous databases. Background technique [0002] In the process of synchronizing data in the heterogeneous database synchronization system, it is necessary to verify the data consistency of the synchronization tables of the source database and the target database to verify the correctness of data synchronization. Hereinafter referred to as the source end database is the source end, and the target end database is the target end. Since the source database is always in the production environment, the data in the source data table is constantly changing. On the other hand, due to the synchronization performance problem of the heterogeneous database synchronization system, there may be a certain period of synchronization delay when the changes in the data table at the source end are synchro...
