Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0034] For the updated target component, the status and jump semantics of the component life cycle are as follows image 3 As shown, the specific explanation is as follows:

[0035] 1) When the component does not receive a dynamic update request, it is in the Normal state;

[0036] 2) When the component receives the update request, it is in the Ondemand state during the update initialization process;

[0037] 3) The update initialization is completed and the component enters the Valid state;

[0038] 4) The component reaches the safe state that can be updated, and the component enters the Free state;

[0039] 5) During the update process, the component is in the Updating state;

[0040] 6) The update is completed, but in the process of clearing the update-related data, the component is in the Updated state.

[0041] For non-target components, the status and ju...

Abstract

The invention discloses a method of service component architecture supporting a software dynamic update. According to the method, an existing SCA (service component architecture) standard is expanded, so that a transaction module and a component life cycle module which support the dynamic update are added, and finally, a Conup platform supporting the dynamic update on Apache Tuscany on an open source of the SCA, and therefore the component dynamic update can be supported in a uniform and efficient mode.

Description

Technical field [0001] The invention relates to a service component architecture technology supporting software dynamic update, and belongs to the technical field of software maintenance. Background technique [0002] Component-Based Software Development (CBSD) technology is considered to be an effective way to improve the efficiency and quality of software development, and has gained wide attention and applications, and has produced many component models and component frameworks. However, as the Internet / WWW gradually evolves into an open computing platform, CBSD derived from the traditional static environment cannot fully respond to the dynamic and variability of user needs and software platforms in an open network environment. [0003] An effective way to respond to changes in requirements and environment is to allow the running component system to be dynamically updated. The mainstream component models and component frameworks have weak support for dynamic updates, while the h...
