Kellyn Gorman continues a series on Oracle Real Application Clusters:
Furthering on our Oracle Real Application Clusters (RAC) knowledge, we’re going to go deeper into what we watch for a RAC database that may be different than a single instance. RAC is built for scale and instance resilience, distributing workloads across multiple nodes. At the same time, what gives it strength introduces monitoring complexity, especially when you’re not just watching a single instance but multiple, interconnected ones. To manage performance effectively in RAC, you need to understand the difference between V$ and GV$ views, what they show you, and how to interpret cluster-level wait events. Along with performance, the overall health of the RAC cluster and interconnect must be known, too.
