AI Technical Summary

Technical Problem

In a dual-machine RBM environment, the lack of a message ordering mechanism can easily lead to one-sided session remnants on the standby machine, affecting the accuracy and reliability of the session and potentially causing service interruptions.

Method used

By triggering the session deletion operation by sending the first message from the RBM host to the RBM standby host, and then performing local session deletion after receiving the standby host's confirmation message, a confirmation mechanism is introduced to ensure the synchronization of the primary and standby host session states.

Benefits of technology

It eliminates the residual sessions on the standby machine, avoids resource waste and business anomalies, and improves the reliability and robustness of the RBM dual-machine hot standby system.

Abstract

The application provides a session hot backup method, an RBM host and a session hot backup system. The method comprises the following steps: sending a first message to an RBM backup machine to trigger the RBM backup machine to perform a deletion operation on a target session of the RBM backup machine; and performing a deletion operation on a local target session when a second message returned by the RBM backup machine in response to the first message is received, wherein the second message is sent by the RBM backup machine after the deletion operation on the target session is completed. Through the confirmation mechanism, the deletion operation of the host is bound to the actual deletion state of the backup machine, which fundamentally eliminates the phenomenon of unilateral session residue of the backup machine, and avoids the problems of resource waste and business anomaly caused by unilateral session residue.
