Problems solved by technology

[0003] The crond program in a UNIX-like system can realize the scheduled execution of tasks, but it uses plain text to define and manage, which is not convenient for task definition, retrieval, and operation monitoring, and lacks fine control over task execution
[0004] There is no additional control on the concurrent execution of tasks. When a large number of tasks are concurrently executed, the system resources are greatly impacted, which may cause the system to be unresponsive for a short time.
[0005] There is no control over the execution time limit of the task, and the task process may hang indefinitely, continuousl

Embodiment Construction

[0068] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0069] The database product adopts MySQL, and the shared memory mechanism adopts the shared memory of the System V standard built into UNIX-like systems. In order to coordinate the synchronous access of multiple processes to the shared memory, the System V standard semaphore is used as the lock synchronization mechanism. The scheduling queue adopts the System V standard message queue and supports message priority.

[0070] In order to improve the concurrency of task information shared memory access, two signal lights are used to control memory synchronous access: one "refresh light" and one "read light". The target effect has three points: multiple processes can read the shared memory at the same time, prohibit other processes from accessing the memory when the memory is refreshed, and prohibit the refresh operation when other processes are accessing t...

Abstract

The invention discloses an optimization method and an optimization system for task scheduling in a large-scale virtualization environment. The optimization method, as a friendly and efficient operation interface for task scheduling, includes task centralized management, distributed execution, smooth control for concurrency, execution time limit control, priority definition, operation monitoring, self-diagnosis, etc. The method is realized in accordance with crond program in a UNIX system, which enhances fine control function and supports cooperation between hosts to realize distributed execution and centralized monitoring of tasks. Task definitions managed by multiple hosts are under centralized management through a database to simplify configuration operation, so as to relieve burden of the database; the tasks are guided into a shared memory after being defined, and the database is not visited in subsequent scheduling. A scheduling platform has self-diagnosis ability, to guarantee sustained and steady scheduling work.

Description

technical field [0001] The invention relates to an optimization method and an optimization system for task scheduling in a large-scale virtualization environment. Background technique [0002] There are a large number of management tasks that need to be performed periodically in a virtualized environment, such as starting and stopping of virtual machines, change detection of configuration parameters, abnormal detection of hosts and application systems, collection and analysis of performance indicators, data backup and cleaning of expired data, etc. . [0003] The crond program in a UNIX-like system can realize the scheduled execution of tasks, but it is defined and managed in plain text, which is not convenient for task definition, retrieval, and operation monitoring, and lacks fine control over task execution. [0004] There is no additional control over the concurrent execution of tasks. When a large number of tasks are concurrently executed, the system resources are grea...
