The Oracle white paper "Oracle Exadata Database Machine Consolidation: Segregating Databases and Roles" demonstrates how to isolate and secure each of the application databases on Exadata Database Machine so that the grid infrastructure as well as the application database can be administered separately and securely. Even while conceding that administrative roles in reality may not be as clearly delineated as the paper considers them, treating the segregation of all databases and their administration from one another with separate diskgroups in a consolidated environment nevertheless offers an opportunity to consider such predictable variations as chargeback requirements or hybrid implementations that involve control by a single administrator of multiple databases, for example. The authors note that the paper does not consider such aspects of the topic as capacity planning, workload management, improved manageability, resulting lower TCO, improved efficiency in the utilization of computing resources, improved service levels and availability, improved skill utilization and reductions in real estate costs.
