Dynamic management system and method for C++ application program version

Abstract

The invention provides a dynamic management system and a dynamic management method for a C++ application program version. The system comprises an application plug-in module, a host program module, an application processing interface module, an application processing interface dynamic registration module, an application plug-in loading / unloading module, an application version distribution module and an application version acquisition module. Application logics are encapsulated into a dynamic shared library by reasonably using dynamic shared library technology, and meanwhile, the application logics are dynamically loaded by designing a system framework; and when the application program version is upgraded, only corresponding dynamic shared library files are upgraded and then loaded through the system framework to realize online update of an application program, and the whole process does not need to shut down and interrupt the service, namely hot plug.

Description

technical field [0001] The invention relates to a system and method for dynamic management of C++ application program version, which updates, expands and enhances application logic without stopping service, and realizes "plug and play". Background technique [0002] At the current stage, when an application system needs to be upgraded when the business logic is adjusted and changed, the following implementation schemes are mainly adopted: one is to apply for a planned downtime and update the application program; the other is to switch to the backup system and update the application program; the third is to adopt Cluster solution, update applications by machine and in batches. No matter which solution is adopted, some systems need to interrupt system services; some online operations or rollback operations after failures are very complicated, which increases the workload of operation and maintenance personnel; some require additional equipment resources to increase operation a...

Problems solved by technology

[0005] Taking the application of TravelSky’s open platform as an example, since the types of business data used and processed by different departments vary greatly, and the business process is also complex and changeable, it is necessary to develop its own special application logic according to the actual situation. If each new application project requires developers to start from scratch Construction is undoubtedly a waste of intelligence and experience, and it also wastes valuable development time
