Embodiment

[0065] Such as figure 2 Shown is the architecture diagram of the application of the monitoring switchback device based on file changes in the embodiment of the present invention, describing the relationship between sending service, receiving service and monitoring service. In this embodiment, take the following market situation as an example: satellite market (main) and ground market (backup). After the present invention detects that the main market is abnormal, it starts to receive the market from the backup source. out, so the market is consistent, and the present invention is used to realize automatic monitoring and switching, and the specific description is as follows:

[0066]First, the business is running normally, and the main system is a third-party application. The third-party receiving program receives real-time files from the upper-level server and writes them to the local or the specified directory on the mapping disk. The third-party receiving program can be a sa...

Abstract

The invention discloses a monitoring back-switching method and device based on file change, and the method comprises the following steps: S1, configuring a monitoring directory and a file, carrying out the real-time scanning through a monitoring module, obtaining the attributes of a local file, and detecting whether the file updating is overtime or not; S2, when it is detected that file updating is overtime, stopping a monitoring module, starting a receiving module, and establishing the connection with a standby server; S3, acquiring the contents of the corresponding file from a standby server, and synchronously updating the data of real-time changes into the corresponding local file. According to the invention, under the condition that the file is updated abnormally, the file updating method and device can be operated rapidly according to an alternative scheme; meanwhile, after an original main program is recovered, main application can be switched immediately, and it is guaranteed that the file cannot be abnormal due to concurrent writing.

Description

technical field [0001] The invention relates to the fields of computer data analysis and data disaster recovery, in particular to a method and device for monitoring and switching back based on file changes. Background technique [0002] With the rapid development of information technology, the requirements for informatization construction in all walks of life are gradually increasing, and the requirements for real-time data transmission and high data availability are also getting higher and higher. [0003] Generally speaking, the quotation files of securities companies will be transmitted from the headquarters to the sales department, and the sales department will generally use the satellite quotations as the main purpose, and the ground quotations at the headquarters as a backup. However, satellite signals are easily affected by extreme weather or interference signals, and market reception is often interrupted. At this time, an automatic switching and switching technology ...
