AI Technical Summary

Technical Problem

In heterogeneous redundant systems, the state synchronization between heterogeneous executors cannot be directly restored by copying in the existing technology, which causes normally functioning executors to have to wait, and the system cannot run continuously.

Method used

By generating a mapping table, determining the first instruction address based on the first synchronization point identifier and the pre-generated mapping table, and jumping to that address through a roll-forward recovery mechanism, the state recovery and progress alignment of the erroneous execution body are achieved.

Benefits of technology

It effectively solves the state synchronization problem between heterogeneous executors, ensuring that executors that are working normally do not wait during the state synchronization process, thus guaranteeing the continuous operation of the system.

Abstract

The application provides a fault point front rolling recovery method, device and storage medium, and belongs to the technical field of computers. The fault point front rolling recovery method comprises the following steps: in the case that a first execution body in a heterogeneous redundant system fails, the first execution body determines a first instruction address based on a first synchronization point identifier and a pre-generated mapping table; and the first execution body jumps to the first instruction address through a front rolling recovery mechanism. The fault point front rolling recovery method provided by the application enables the faulty execution body to recover the state and jump to the instruction address at which the progress of the other normally working execution body is aligned, effectively solves the state synchronization problem between the heterogeneous execution bodies in the front rolling recovery mechanism, and thus realizes that the normally working execution body does not need to wait during the state synchronization process, and guarantees the continuous operation of the system.
