Abstract

The invention discloses a data synchronization method during the process of software upgrade, and is mainly applied to the hot-standby systems of a mainframe and a main processor of the mainframe, a standby host and a standby processor of the standby host; the main processor is provided with a main data synchronization management module and a business module of the mainframe; the standby processor is provided with a standby data synchronization management module and a business module of the standby host; the method includes the steps as follows: step 1, description information in the data field of the standby host can be registered and sent to the standby host synchronously by the main data synchronization management module; description information in data field of the mainframe can be registered and sent to the mainframe synchronously by the standby data synchronization management module; step 2, after the business module of the mainframe send the contents of the data field to the standby host synchronously, the standby data synchronization management module carries out the reconstruction processing of the contents in the data field according to the description information in the data fields on the mainframe and the standby host; The invention realizes the seamless software upgrade of the hot-standby system during the process of the version upgrade of the mainframes and standby hosts.

Description

technical field

[0001] The invention relates to data synchronization technology, in particular to a method for data synchronization in the software upgrade process in a dual-machine hot backup system. Background technique

[0002] Dual-system hot backup is a widely used technology in systems that require high reliability. Dual-system hot backup can seamlessly switch the standby processor to be the main one in the event of a failure of the main processor. In the event of a point failure, the business of the entire system is guaranteed to be uninterrupted. This technology is widely used in communication and other fields.

[0003] In a dual-machine system, in addition to running the same software program on the active and standby machines and having mutual status monitoring and active-standby switching logic, data synchronization is also an important part, because each business module needs to record a large number of intermediate data during operation. These data need to be ...
