Abstract

The invention discloses a master and slave switch method and device of a task scheduling example. According to one specific implementation mode of the method, at least two examples which are set in advance and used for executing task scheduling work judge whether an election time arrives or not according to a respective election cycle and opening time, wherein attribute information of all the examples comprises an example identification, the election cycle, whether to participate in a main example election or not and master and slave states; if the election time arrives, the attribute information is information recorded in a main example information table which is created in advance in an example renewing database in which the main example election participates; if renewing is successful, the master and slave states of the examples which are renewed successfully are in master states, and the master and slave states of other examples except the examples which are renewed successfully are in slave states; the examples of which the master and slave states are the master states execute task scheduling work. The master and slave switch method and device of the task scheduling example are simple in implementation mode, and efficiently achieve master and slave switch of the task scheduling example.

Description

technical field [0001] The present application relates to the field of computer technology, specifically to the field of Internet technology, and in particular to a master-slave switching method and device for task scheduling instances. Background technique [0002] In systems that require distributed processing of time-series-based high-concurrency tasks, if the program instance performing task scheduling fails, it may result in missing tasks or even the unavailability of the entire system. Therefore, in order to ensure that each task is executed on time without omission, it is necessary to consider using at least two program instances responsible for task scheduling. When the program instance in the working state fails, one of the other program instances can automatically take over its work to make the system run normally. At the same time, in order to ensure that the tasks in the same time period are not executed repeatedly, it needs to be satisfied that only one of the ...
