Embodiment Construction

[0066] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. .

[0067] Embodiments of the present invention provide a lock management method and system, and a lock management system configuration method and device, which can configure the lock management system according to the number of processing processes and manage the locks of the processing processes. The present invention is applied to a distributed system. The distributed system includes at least two business execution nodes and a central control node. Each of the business execution nodes runs a corresponding system instance through at least one processing process, and at the same time executes the process through the central control node. Sharing and contro...

Abstract

An embodiment of the invention discloses a lock management method, a lock management system, a lock management system configuration method and a lock management system configuration device, and relates to the field of computers. Lock access delay can be decreased, and the running performance of the system is improved. The specific scheme includes that a corresponding lock management system level is set for each business execution node according to the number of business execution nodes in a distributed system, the number of system cases on all the business execution nodes, the number of processes and access delay from each business execution node to a central control node of the distributed system; at least one lock manager is distributed for each business execution node according to the lock management system level corresponding to each business execution node; a lock level context is configured for each lock manager and used for determining a lock manager adjacent to each lock manager. The lock management system configuration method is used for the lock management system of the distributed system.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a lock management method and system, and a lock management system configuration method and device. Background technique [0002] In a distributed system, data is shared by processes distributed among multiple business execution nodes. To perform operations on any resource, a process must obtain a lock in advance. The control of concurrent access between different processes is implemented by the global lock manager, which records the status of each process accessing resources and holding locks, and maintains the lock waiting queue. When the global lock manager receives a lock request, it decides whether to satisfy the lock request according to the lock type, lock compatibility and lock holding status. [0003] The existing lock management system adopts global and node lock manager coordination technology. Each system instance in the business execution node has a node lock manager...
