Summary
In this chapter, we discussed the concepts of High Availability Disaster Recovery and auxiliary topics. We also discussed a framework to design a Business Continuity Plan (BCP) that can be used to map business processes to IT infrastructure needs for mission-critical Oracle application environments. Among the core topics, we have covered:
High availability concepts
How Oracle 11g RAC provides high availability
High availability solutions for Oracle 11g R1 and 11g R2 Real Application Clusters (RAC)
After explaining high availability, we discussed how each of the various Oracle technologies provide the Maximum Availability Architecture (MAA) for the large data center environment, as well as how to leverage these to best achieve maximum Return on Investment (ROI) within the Oracle data center. Finally, we explained why Oracle RAC is a high availability solution, as well as why it is not a disaster recovery solution.
In the next chapter, we will provide you with a detailed blueprint of how to design a solid Oracle RAC infrastructure for your data center environment and how to select and implement hardware, storage, and software for a robust Oracle 11g RAC configuration in the best possible manner.
