Oracle Real Application Clusters 10g Release 2 - Technical Comparison with Microsoft SQL Server 2005
http://www.oracle.com/technology/products/database/clustering/pdf/twp_rac_compare_sqlserver2005.pdfThe cluster database market is rife with competing marketing claims, with each vendor touting the benefits of its own architecture. The buyer has to make the choice of a mission-critical software platform while sifting through a mass of rapidly evolving benchmark results, conflicting analyst reviews and uniformly positive customer testimonials.
This paper is a technical evaluation of three different database technologies from Microsoft: the ‘Federated Architecture’, the ‘Failover Clustering Architecture’ (managed by MS Cluster Server) and the ‘Database Mirroring Architecture’ as represented by Microsoft SQL Server 2005. Each of these technologies is compared to Oracle’s clustered architecture: Oracle Real Application Clusters10g Release 2. Oracle RAC forms part of Oracle’s High Availability Architecture, which further enhances protection for the database from disasters.
The Federated and Failover Clustering architectures have existed in previous versions of SQLServer. The Microsoft Database Mirroring technology is a new SQLServer 2005 feature.
