Embodiment 2

[0072] as attached image 3 As shown, the execution system of the distributed timing task adopting the implementation method of the distributed timing task in Embodiment 1 includes several nodes, and several nodes share a database, and each node is provided with a task execution module and a heartbeat monitoring module ;

[0073] Among them, the task execution module is mainly responsible for task execution and update of task status;

[0074] The heartbeat monitoring module is mainly responsible for updating the heartbeat time and resetting the state when the task execution is abnormal.

Abstract

The invention relates to the technical field of a computer and specifically provides a realization method and performance system for distributed timed tasks. The performance system for the distributed timed tasks comprises a plurality of nodes, wherein the plurality of nodes share the same database; each node is equipped with a task performance module and a heartbeat monitoring module; the task performance module is mainly responsible for performing the tasks and updating task states; and the heartbeat monitoring module is mainly responsible for updating heartbeat time and resetting the states when task performance is abnormal. Compared with the prior art, the realization method and performance system for the distributed timed task provided by the invention have the advantages that distributed cluster deployment is supported, so a single-point fault can be effectively avoided; moreover, the tasks can be effectively prevented from being performed repeatedly, the realization complexity is low, and the research and development cost can be effectively reduced; the dependence of software products on external software products can be effectively reduced, so the risk and uncontrollability are reduced; and moreover, the realization method and the performance system can be integrated with the software product rapidly, and the realization method and the performance system have high popularization and application value.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for realizing distributed timing tasks and an execution system. Background technique [0002] In the software field, scheduled tasks are often used. When deployed on a single node, there are single point of failure and performance problems; when deployed in a cluster, there is a problem of repeated execution of tasks; external professional scheduled task plug-ins are used, which are intrusive to the business code Strong, high risk, uncontrollable. [0003] Patent No. CN 106569878A discloses a distributed timing task management method and system, wherein the method includes: judging whether the current time matches the execution time of the task to be executed; Server state information; when the current time matches the execution time, select an execution server that matches the task to be executed from the plurality of distributed servers according to the server state informati...
