Embodiment Construction

[0025] Introduced below are some of the various embodiments of the invention, intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of protection.

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] In the task scheduling mutual backup method of the present invention, the task scheduling service schedules the tasks in the manner of "preempting" the tasks respectively, and after the task scheduling service obtains the tasks, it distributes the tasks, that is, calls the subsequent task processing services. After the current round of task scheduling is over, the task server will start a new round of task acquisition.

[0028] Specifically, the core of the task scheduling mutual backup method of the present invention is that task scheduling services are independently deployed on different hosts, and each task...

Abstract

The invention relates to a task scheduling mutual backup method. The method is used for performing scheduling mutual backup tasks stored in a database server by utilizing more than two applying masters, and includes an initialization step, namely reading the task number X of each scheduling in the configuring files in the applying masters through task scheduling service of the applying masters; a task scheduling service step, namely acquiring last X task records from a task information list of the database server through the task scheduling service in a mutex manner according to task time sequences; a task distribution step, namely distributing the acquired tasks from the applying masters one by one through the task scheduling service. By the aid of the task scheduling mutual backup method, system reliability can be improved effectively.

Description

technical field [0001] The present invention relates to a computer data processing technology, more specifically to a method for improving the reliability of a computer system. Background technique [0002] In the existing computer data processing technology, for a multi-task concurrent processing system, if the 24-hour uninterrupted operation of the system cannot be guaranteed, the stability of the system will often be greatly reduced. Especially for some systems that require high real-time processing of tasks, if the task scheduling service stops working when an exception occurs in the system, it will not help even if the system can support a large amount of concurrency. [0003] In many multi-task concurrent processing systems, the cold standby mechanism is generally adopted for the task scheduling service. The so-called cold standby mechanism means that under normal circumstances, only one task scheduling service performs task scheduling, and other task scheduling servi...
