Anti-duplication method and device for double-log-surface cross-day switching period

Abstract

The invention discloses an anti-duplication method and an anti-duplication device for a double-log cross-day switching period, which can be used in the financial field or other technical fields, and the method comprises the following steps: when a platform calls a host to carry out transaction processing, if the transaction processing of the host is abnormal, judging whether the current system date of the host is the same as the transaction date of the transaction; if the current system date of the host is different from the transaction date of the transaction, registering empty rollback records corresponding to the transaction in a host channel log table corresponding to the current system date and a host channel log table corresponding to the transaction date respectively, wherein the empty rollback records comprise event number fields, and the field value of the event number field is equal to the field value of the forward host event number field. According to the method, the null rollback and anti-suspension functions of the distributed platform transaction accessed by the host during the cross-day switching period are realized.

Description

technical field [0001] The present invention relates to the technical field of distributed transaction processing, in particular, to a method and device for anti-duplication during a double-log plane cross-day cut period. Background technique [0002] As more and more applications are implemented in distributed systems, the logical complexity of the system increases, and the requirements for handling emergencies are higher. However, in production, the relationship between different applications and service calls is intricate. Once a network delay or logic problem appears suspicious in a certain link, the program will rely on the channel log to achieve empty rollback and anti-hanging. If the channel is initiated repeatedly and the service provider does not control it, it may lead to repeated transactions; if the service provider only controls the repetition and does not return the processing result of the previous transaction, the customer will not be able to perceive the tra...

AI Technical Summary

Problems solved by technology

However, in a small number of cases, due to the double-sided design of the channel log, the idempotent, empty rollback, and anti-suspension mechanisms will fail during the cross-day switch period.

For example, for empty rollback and anti-suspension, if a transaction order registers an empty rollback record on T day, but due to reasons such as the DSR network or system environment on T day, the order resumes sending on T+1 day, resulting in a There are two different transaction states in the pen command at the same time, resulting in empty rollback and failure of the anti-suspension mechanism

[0004] In order to solve the situation of empty rollback and anti-suspension mechanism failure caused by specific circumstances, this solution proposes an anti-heavy method during the period of double-log face cross-day cut
