Digital Organisms Database Research And Implementation Of Exception Handling Mechanism

Internet and computer technology along with the rapid development of technology for distributed and parallel processing technologies are deeper study. The research of 8010 laboratory based on the concept of the digital organisms, through the distributed system will be geographically separated resources (nodes) into an organic whole, forming a complete computer platform, and really provide services in parallel. The digital organisms database is essential in this creative component. This article is a discussion and implementation of fault in the digital organisms.Compared to traditional databases, digital organism database need more data security and consistency demanding.In the digital organism database design philosophy, we demand that any fault can not affect the overall performance of the system, unless all the resources of all the damage. So, dealing fault of digital organisms database has become the focus of unusual and difficult. In this paper, we use a lot of ink to discuss the digital organisms database happen abnormal treatment methods, trying to be justified.Through detailed design and many tests, the digital organisms database may have a variety of anomalies have a full understanding, we are likely to respond to various situations, trying to ensure that services are not affected the whole system, or try less affected. In this article we should be adopted for testing methods and the program also has a detailed description.Generally speaking, the digital organisms database for the study of exception handling must have the innovative. In order to verify the exception handling mechanism of an organism database study, we realize the digital organisms database consistency at the Weakly consistent state. Node information through the real-time and timing inquiries, and the node directory synchronization measures, the reliability of the database implementation. These also have be discussed in this article.Digital organisms database platform as the database system in e-government, multimedia services, such as availability and reliability for demanding application areas and sectors shows that the number of organisms to solve the multi-node database changes and fault status of the remodeling questions to ensure the system's high reliability and high availability.At present, the digital organism database is running well.
