Problems solved by technology

[0004] In the research on the prior art, the inventor found that: although the above scheme can prevent a task from being reloaded by multiple server nodes, since the task can only be executed on a specific server node, when a server node fails When , the task bound to the server node will also fail, and the failure of the task will reduce the reliability of the system

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0023] First introduce the task switching system provided by the embodiment of the present invention, figure 1 The structure of an embodiment of a task switching system is described in which:

[0024] The first server node 101 is used to obtain the update timestamp of the second server node 103 from the database 102; after judging that the second server node 103 is invalid according to the update time in the update timestamp, the second server node 10...

Abstract

The invention relates to the technical field of communication, disclosing a target switching method, a server node and a colony system. The target switching method comprises: a first server node obtains a update time stamp of a second server node from a database; the first server node judges whether the second server node is invalid according to the update time in the update time stamp; if the second server node is invalid, the first server node updates a task bound with the second server node in the database to be bound with an effective server node and sends the definition of the task bound with the second server node to the effective server node. The technical scheme provided by the embodiment of the invention causes the task bound with the invalid server node to be performed on other effective server nodes so as to improve the reliability of the colony system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a task switching method, a server node and a cluster system. Background technique [0002] The execution of tasks in the application system is exclusive, and there is one instance of a task at any time, and the task can be a scheduled task or a non-scheduled task. In order to improve the disaster recovery capability and performance of the application system, the cluster technology is applied more and more. In a cluster environment, each server node is deployed with the same system, and these server nodes share a database. Therefore, multiple server nodes may obtain the same task in the same database at the same time (such as starting or restarting the process), so that It will cause a task to be reloaded by multiple server nodes, so that one task becomes multiple task execution. [0003] In order to prevent one task from being executed by multiple tasks, an existing solut...
