Abstract

The invention relates to a method, a device and a system for realizing a task under a cluster environment. In the embodiment of the invention, the designated application in the cluster environment obtains the task from a database, and the obtained task is loaded; a task example is created, and is stored in a memory of a server where the designated application belongs to, thereby avoiding the circumstances that the task in the database is loaded repeatedly in the cluster environment.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a method, system and device for realizing tasks in a cluster environment. Background technique

[0002] In order to improve the disaster recovery capability and performance of the system, cluster technology is more and more applied. However, once many functions of the previous stand-alone version are migrated to the cluster environment, problems may arise. For example, to realize the task function, because the application of each server node shares the database in the cluster (as shown in the attached figure 1 shown), therefore, multiple applications in different servers may obtain the same task in the same database at the same time (such as the startup or restart process), which will make a task may be repeatedly loaded by multiple applications, resulting in a Tasks were mistakenly turned into multiple tasks executing.

[0003] In order to avoid the occurrence of the a...
