Embodiment Construction

[0129] The application will be described in further detail below in conjunction with the accompanying drawings.

[0130] figure 1 A topological diagram of a system for serving distributed locks according to one aspect of the present invention is shown, which includes a network device 1 and a plurality of user devices 2 connected to it via a network.

[0131] Among them, the network device 1 can be connected to multiple user devices 2 via the network. After the user device 2 (that is, the user device 2) establishes a connection with the network device 1 (that is, the network device 1) in the distributed lock service system, a The user equipment 2 thread (Session) binds the user equipment 2 to the session with the network equipment 1, and the user equipment 2 and the network equipment 1 update the session lifetime through regular heartbeats. The user equipment 2 will update the lifetime of the user equipment 2 thread on the corresponding connection through regular heartbeats wi...

Abstract

The invention aims at providing equipment and a method used for realizing distributed lock management, and the equipment and the method are based on public management information. Through disclosing management information of a distributed lock owner and validity period information, the distributed lock owner and the validity period information which are originally entrusted to thread management between user equipment and network equipment are publicized so that a service layer can high-efficiently and flexibly customize a distributed lock service according with a service scene. Further, a user equipment process which fails to grasp distributed locks actively subscribes a distributed lock file; when a distributed lock possessor process actively releases the distributed locks, each user equipment process can timely acquire a change notice so as to grasp the distributed locks again; and finally a switching process of a distributed lock owner is accelerated.

Description

technical field [0001] The present application relates to the field of computers, and in particular to a technology for implementing distributed lock management. Background technique [0002] Each computing node in a large-scale cloud computing system needs to coordinate its own actions, or access a group of shared resources with mutual exclusion. These actions all need to rely on distributed lock services to prevent mutual interference and ensure distributed data consistency. Distributed locks are widely used in large-scale distributed computing environments. User device processes distributed on different computing nodes usually rely on distributed locks to access shared resources to ensure data distributed consistency. [0003] Under the existing implementation technology, the management of the owner and validity period of the distributed lock is actually the distributed lock management established between the user equipment and the network equipment, and the distributed l...
