Chapter 3 - High
Performance and Highly Available
Database Clusters
Conclusion
In this chapter, we have discussed details
about high performance and high available database systems, overview
of cluster technology, and various types of clusters. There was
particular emphasis on database clusters and its requirements for
data consistency and concurrency.
Failover clusters are widely used for deploying
high available databases. Many cluster vendors provide cluster
software or agents, which support relational database failover
process. Parallel Database Clusters, which allow concurrent access
to data blocks form multiple nodes or instances, have to deal with
more complicated issues like cache coherency and lock management. We
have also covered different architectures of parallel database
clusters, and we also focused on the requirements for a stable
parallel database cluster product.
In next chapter, we will cover concepts and
general features of Real Application Clusters (RAC), including
architectural details and all the components.
