Embodiment Construction

[0041] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042]The reason for the conflict between clustering technology and caching technology is that the cached data between servers is not synchronized. The effective solution is to synchronize the cached data on different servers. The invention provides a method and an application system for synchronizing cached data in a cluster environment. The cache technology is used on each cluster server. The server judges whether there is data to be called by the client in the local cache, and further judges the data in the cache. Whether the data is invalid, to solve the problem of out-of-sync between the cache and the database, and ensure that the data returned to the client is the latest data.

[0043] In the database application system, som...

Abstract

This invention discloses a data buffer storing method and a system under cluster environment, in which, the method includes: a customer end sends a data calling request, a server enquires if there are data to be called in the loca buffer storage, if not, it enquires the database, if so, it judges if the buffer storage data are invalid, if not, it returns the data result to the customer end directly, if so, it enquires the database to return the result to the customer end and writes it in the buffer storage, therefore, it guarantees that the data result to the customer end by the server is the newest and the method will not break the character of cluster technology.

Description

technical field [0001] The invention relates to database application technology, in particular to a data caching method and system in a cluster environment. Background technique [0002] In the database application system, in order to meet the performance requirements of large-scale applications, there are usually two technical solutions on the server side of the application system: cluster technology and cache technology. Among them, the cluster technology is to enable individual servers to be connected physically and programmatically, and to carry out cooperative communication between the servers so that they can perform common tasks; even if a certain server stops running, the emergency process will automatically The server's workload is shifted to another server to ensure continuous service. Therefore, cluster technology can improve the computing power of the system through parallel computing of multiple servers. The caching technique refers to avoiding repeated calcul...
