Problems solved by technology

[0003] Due to the isolation characteristics of the one-way optical gate, it is impossible to use the database synchronization tool provided by the database developer itself for database synchronization. The single-direction manufacturer must realize the database synchronization function by itself according to the demand

Abstract

The invention discloses a method for realizing heterogeneous database synchronization of unidirectional optical gates on the basis of data flow analysis. According to the method, data synchronizationof heterogeneous databases in unidirectional optical gate systems is realized through monitoring package capture analysis manners of source database server ports.

Description

technical field [0001] The invention relates to the field of single guide applications, in particular to a heterogeneous database synchronization method for realizing one-way optical gates based on data flow analysis. Background technique [0002] The heterogeneous database synchronization technology in the one-way shutter system is to realize data synchronization on the basis of the one-way shutter system. The transmission of the one-way shutter system is to use the physical one-way transfer characteristic of optical technology. Sending mode, the shutter system is composed of an inner end and an outer end, the outer end includes a database synchronization module and a data sending module, the outer end sending module is only responsible for sending data; the inner end includes a database synchronization module and a data receiving module, and the inner end receiving module only Responsible for receiving data, there is only data flow information but no control information fl...
