Database resource integration of shared cloud platform based on RAC architecture

This paper focuses on the core problem of database resource integration mode. The theme of this paper is the construction and implementation of database resource integration model, and some legal and commercial constraints related to it, so the content of the research involves the integration of technology, integration system, the integration of the status analysis and other aspects. The basic concept, classification, structure system and basic principles of Oracle RAC are discussed. Combined with business needs, a solution based on Oracle RAC is proposed. We implemented the planning and deployment of shared storage, file storage and network setup based on Oracle RAC database. The automatic failover without user intervention is realized, which greatly improves the reliability of the database, and has a certain guiding significance for the application and construction of the enterprise database. First, the research status of database resources integration at home and abroad is expounded through literature analysis. Secondly, the model of database resource integration is put forward, and its realization is discussed. Thirdly, the status of database resource integration is analyzed. Finally, the problems to be solved are put forward in the end. Through the research of this topic, it provides some reference and basis for the database resource integration model. At the same time, it also makes a paving for the maximum elimination of information isolated island and promoting the sharing of database resources.
