Method and system for dynamic data synchronization

Abstract

The invention relates to a method for dynamic data synchronization. When the dynamic data of a host computer is changed, the method includes the steps as follows: the host computer builds the synchronous request data of the record according to the record corresponding to the changed dynamic data, and transmits the synchronous request data to the record level synchronous process; the operation information is recorded according to the synchronous request data or the synchronous request data and the buffer zone of the global data, and the synchronous information is built through the synchronous rule and transmitted to a standby unit; the standby unit performs the synchronous operation for the required synchronous record in a synchronous manner according to the synchronous information transmitted by the host computer; after the standby unit achieves the synchronous operation of the record, the synchronized record is deposited and the response information which is synchronously achieved istransmitted to the host computer; after the host computer receives the response information, the changed dynamic data is synchronously achieved, and the synchronous operation is finished; the invention also discloses a system for dynamic data synchronization, and the method and the system of the invention can synchronize the dynamic data between the memory databases of the host computer and the standby unit in real time.

Description

technical field [0001] The invention relates to a memory database backup technology, in particular to a method and a system for synchronizing dynamic data between main and standby memory databases. Background technique [0002] In-memory databases are often used in telecommunications equipment for data management. To ensure data security, an active and standby database must be used. The main database is on the main machine, and the standby database is on the standby machine. In the application, all services are operated on the main machine, and the generated data is also stored in the memory database of the main machine; the function of the standby database is to actively or passively communicate with the main machine. The database synchronizes data. When the primary database is decommissioned, the standby database becomes the primary one to keep the business running normally. [0003] Due to the continuous operation of the business on the host, the data in the memory datab...

Problems solved by technology

However, these two methods are not real-time for the synchronization processing of the main and standby memory databases, and take up a lot of memory space, resulting in a waste of memory space and increasing memory overhead; at the same time, due to the Data synchronization messages are records that need to be synchronized one by one, so the amount of synchronization messages exchanged between the master and backup machines is very large, which affects the performance of the system
