Problems solved by technology

[0008] In the above process, the transaction coordinator may fail to receive the branch transaction addition request within the specified time or the transaction participant may fail to receive the call request within the specified time due to a network timeout. At this time, timeout processing will be performed. That is, a rollback request is initiated to the transaction initiator to request rollback processing
Because the rollback process may occur before the transaction coordinator creates the branch transaction record locally, or before the transaction participant creates the preprocessing record locally, the branch transaction executed by the transaction participant will not be rolled back, resulting in rollback suspension

Abstract

The invention provides a rollback processing method and apparatus. The method is suitable for distributed transaction, and the distributed transaction relates to a transaction initiator, a transaction participant and a transaction coordinator. The method comprises the steps that a rollback request initiator receives a rollback processing request, wherein the rollback request initiator is the transaction participant or the transaction coordinator; the rollback request initiator obtains first time according to starting time of the distributed transaction and a specified time interval; and the rollback request initiator performs rollback processing when the first time is earlier than current time. According to the rollback processing method and apparatus, the problem of rollback suspension in the distributed transaction can be solved.

Description

【Technical field】 [0001] The present application relates to the field of computer technology, in particular to a rollback processing method and device. 【Background technique】 [0002] The transaction participants, transaction initiators, and transaction coordinators involved in distributed transactions are located on different nodes of different distributed systems. The transaction initiator is responsible for initiating distributed transactions; the transaction coordinator is responsible for managing the life cycle of distributed transactions and all branch transactions in distributed transactions; transaction participants are responsible for executing branch transactions in distributed transactions. [0003] The existing distributed transaction processing flow is as follows: [0004] The transaction initiator sends a transaction request to the transaction coordinator to indicate the initiation of a distributed transaction; the transaction coordinator creates a master tran...
