Information synchronization system and method

Abstract

The invention provides an information synchronization system and method. The system comprises a data processing module, a positioning module, an information acquiring module and a notifying module. The data processing module acquires shared resource information and / or requester information of shared resources of a distributed system and transmits the information to the positioning module. The positioning module is used for acquiring an identification of a requester of the shared information and / or the identification of an occupier of the shared resources according to the requester information and transmitting the identification to the information acquiring module. The information acquiring module is used for respectively converting the identification of the requester of the shared information and / or the identification of the occupier of the shared resources into corresponding the occupier attribute information identification and / or the requester attribute information identification and transmitting the occupier attribute information identification and / or the requester attribute information identification to the notifying module. The notifying module is used for notifying sharing state of the shared resources. By the system, positioning of the shared resource occupier and sharing of state of the shared information can be achieved conveniently.

Description

technical field [0001] The present application relates to the technical field of distributed networks, in particular to an information synchronization system and method in a distributed system. Background technique [0002] In a distributed system, resources that can only be uniquely occupied at a time are called shared resources. Shared resources have the characteristics of global uniqueness, such as the designated port (Port) of the centralized server and a specific piece of data in the database table. Such resources will be locked when they are occupied by a certain user to prevent conflicts caused by concurrent access by other users. [0003] Due to the exclusiveness of the shared resources of the distributed system, when the shared resources are occupied, other users' applications (preemption) for the shared resources will be rejected. At this time, the preemptor needs to find the occupant of the shared resource, and the occupant also needs to receive a notification th...

Problems solved by technology

At this time, it is usually necessary to locate the person who is currently Remote Debugging and communicate with him offline to coordinate the use of the problem. For a large or geographically dispersed development team, it is very difficult to locate the occupant of the resource. Similarly Difficulty increases with team size

[0005] The occupancy location of Internet shared resources mainly relies on offline communication between users of the distributed system, combined with certain technical means, such as searching occupancy information on the server, manually searching occupant information based on occupancy information, etc., there are the following One or more questions: (1) Question 1, certain skills are required, and users need to have a deep understanding of relevant positioning technologies in order to quickly and effectively locate shared resource occupants; (2) Question 2, because it is manual positioning, positioning is often more difficult Large, affecting work efficiency, if there are many shared resources, it will be a lot of work to find; (3) Problem 3, offline communication costs are high; (4) Problem 4, too much reliance on manual work, low degree of automation
