Research On The Optimization Of Oracle Database RAC Clusters Based On Linux

In recent years, Oracle RAC cluster server to obtain a wide range of development and application. Particularly in data services for SMEs, a significant reduction in operating costs, improve resource utilization. This paper first describes the deployment and maintenance issues Oracle RAC cluster server under Linux system, combined with the theory and practice of a bold attempt to achieve the Oracle RAC cluster server, perfect RAM data backup and recovery manager and Data Guard Data Guard combined, significantly enhance the security of the data in the database of resources, little change can be applied directly in the production environment. At higher data security requirements for the database environment, this system is particularly outstanding.In view of this, the main work of this paper focuses on the following aspects. First, the background and significance of the research outlined Oracle RAC server clustering technology for Oracle RAC server clustering technology background to do extensive market analysis. Elaborated on the basic concepts of Oracle RAC Real Application Clusters, composition structure, working principle and part of the basic principles of critical components is described in detail. Then the process and considerations to deploy Red Hat Linux system environment were elaborated on the steps to create a database instance to make a note, and integrated RAM and DataGuard technology cluster servers, making the database system in high availability and data security on has been further improved. Finally, Oracle RAC Real Application Clusters optimized for performance and stress testing, including speed mass data import, failure transparent switching, etc., makes the ORACLE RAC cluster server performance has intuitive evaluation.
