Abstract

An embodiment of the invention provides a distributed transaction committing failure handling method and device. The method includes the steps: recording the state of a distributed transaction as an unfinished state by a first node after committing the distributed transaction at a first stage; transmitting a transaction state query request including the sign of the distributed transaction to a second node according to the recorded unfinished state of the distributed transaction after the first node fails or network connection between the first node and the second node fails and failure recovers; repairing the distributed transaction at a second stage according to the state of the distributed transaction returned by the second node. By the method, the problem that the distributed transaction cannot be automatically repaired when second-stage committing failure of the distributed transaction occurs can be solved, and atomicity and uniformity of the distributed transaction are ensured.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method, device and system for processing distributed transaction commit failures. Background technique [0002] Transaction is the smallest logical unit of work for an operation sequence to access the database for specific business functions, usually including local transactions and distributed transactions, also known as global transactions. [0003] A distributed transaction means that a transaction may involve multiple database operations, for example, several different databases may be updated in one transaction. After operations are performed on these databases, all modifications to these databases must be committed or rolled back. Committing refers to writing the modified data to disk, and rolling back refers to canceling the modification. Some databases are not allowed to be submitted while others are not. Commit, this feature is called transactio...
