Problems solved by technology

[0007] For the situation where multiple types of data sources are distributed on multiple machines, the existing transaction processing methods cannot meet the requirements, because if one of the database servers fails, it cannot ensure that other databases still have uncommitted data rollback
In other words, without the ability to coordinate multiple transactions happening in different places, there is no way to guarantee transaction atomicity
[0008] Therefore, how to solve the data inconsistency caused by abnormalities in the cross-database operation in the distributed system has become a technical problem to be solved urgently

Abstract

The invention provides a crossing-base transaction processing method and system based on relational databases. The method comprises the steps of building a plurality of database connection pools, and allocating corresponding names to the database connection pools for storing a plurality of data sources; building the incident relation between a plurality of SQL statements and the data source names, and storing the incident relation into a buffer region; traversing the SQL statements, obtaining the corresponding data source names from the buffer region according to the SQL statements, obtaining the data source from the database connection pools through the data source names, and writing the SQL statements into log files; executing the SQL statements, storing a plurality of corresponding execution results, and setting data source transaction control switch states according to the execution results. According to the technical scheme, data synchronization among all the databases can be effectively ensured.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a relational database-based cross-database transaction processing method and a relational database-based cross-database transaction processing system. Background technique [0002] With the increasing business requirements, the application program becomes more and more complex, and often needs to access multiple databases, and these databases are usually distributed in different places, which constitutes a distributed transaction. Data modified by a distributed transaction is stored in multiple or types of data sources distributed across multiple machines, and there are even more complex cases. [0003] All operations in the transaction are either completed or not performed. The condition for the success of the transaction is that all operations in the transaction are successful. As long as one operation fails, the entire transaction fails and needs to be rolled back. For exam...
