Embodiment Construction

[0074] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0075] In order to solve the problem of cross-sky scheduling, the present application provides a task scheduling method and device, which can solve the problem of system limitations in task scheduling.

[0076] A log is a record of transactions or actions that have taken place on a computer system. By analyzing the log files, you can learn more about the entire running process of the system. In the process of log parsing, it is necessary to perform various operations on the log. The operation performed on the log can be regarded as a task. For example, downloading the log can be regarded as a task. To perform the task of downloading the log, the Tasks need to be scheduled, and then the tasks are sent to...

Abstract

The invention provides a task scheduling method and a system and aims at solving the problem of limitation of a system in task scheduling. The task scheduling method includes the following steps. Firstly, a task which is mature based on a set time are selected and designated as a postposed task. Plan performing time of a preposed task is calculated through a task scheduling reliance dimension table of the postposed task and a task sequence number of the preposed task is read from the task scheduling reliance dimension table. A performing state of the preposed task in a task scheduling operation result list is found out according to the task sequence number and the plan performing time of the preposed task. If performing is successful, the postposed task is lined up in a task queue and waits for scheduling performing. Under all circumstances, as long as a postposed task is confirmed, a preposed task can be found out and the postposed task can be performed as the preposed task is successfully performed so that the task scheduling system is modified. Scheduling time is shortened, scheduling efficiency is improved and fault rate is reduced.

Description

technical field [0001] The present application relates to log technology, in particular to a task scheduling method and system. Background technique [0002] A log is a record of transactions or actions that have taken place on a computer system. In various application systems, such as banking system, portal system, e-commerce system, company's internal financial system and other application systems, everything that happens during the system operation will be recorded as a log, and log files will be generated, and then passed By analyzing the log files, you can get a detailed understanding of the entire running process of the system. [0003] In the process of log parsing, it is necessary to perform various operations on the log. The operation performed on the log can be regarded as a task. For example, downloading the log can be regarded as a task. To perform the task of downloading the log, the Tasks need to be scheduled, and then the tasks are sent to the operating syst...
