Abstract
The invention relates to a system for refreshing caches on the basis of an HTTP (hypertext transfer protocol). The system is communicated with at least one host monitor, and comprises a host information table module, a host display page module, a cache scheduler, a refreshing monitor and a cache information table module; the host information table module is used for storing URLs (uniform resource locators) of all the host monitors and comprises host IPs (internet protocols) and refreshing ports corresponding to the host IPs; the host display page module is used for reading the URLs of the host monitors and displaying the host IPs and the refreshing ports corresponding to the host IPs to a user; the cache scheduler is used for analyzing the certain host IP selected by the user and the refreshing port corresponding to the certain host IP to form HTTP information, and then transmits the HTTP information to the refreshing monitor; the refreshing monitor is used for calling the HTTP information transmitted by the cache scheduler and reading HTTP information, which is processed by the corresponding port, in the cache information table module; and the cache information table module is used for storing all refreshable ports. The system has the advantage that the caches can be remotely refreshed in real time in a batch manner.
Description
Technical field
The present invention relates to the caching process technical field, particularly relate to a kind of cache flush system based on http protocol and buffer memory method for refreshing.
Background technology
The most application for performance considered all can adopt caching technology at present, generally is that the data that some are commonly used read out former data and be cached from the data sources such as configuration file when starting in system, needs flush buffers if former data have modification.
Each channel can recognize that existing cache flush mainly passes through dual mode by inquiry:
One, periodic refreshing, it adopts the apache-configuration framework, and this framework provides FileChangedReloadingStrategy periodic refreshing scheme, namely is configured at set intervals the inspection of file modification date.Its drawback is: 1. the bad control of refresh interval, arrange too smallly, and the consumption useless to system is larger; Arrange excessively, then real-time is very poor, and buffer memory can not get in time refreshing.2. it can only be for the configuration of document form, if adopt the buffer memory of other form of database then helpless.
Two, staff refreshes, namely when former data modification, certain monitoring URL of artificial access triggers and refreshes, its real-time is very strong, but drawback is: each interface has the URL that refreshes of a correspondence, needs manually to carry out URL to each interface to be refreshed and calls, if in the more situation of the interface that refreshes, very waste of manpower also easily makes mistakes.Especially under cluster environment, need to carry out time operation of M interface of N platform main frame *.。
