Under the covers of Oracle Real Application Cluster deployments
summary
Shows concrete 23c features and deployment tradeoffs: introduces PDB ranking/importance plus CPU fractional min guarantees, placement policies Fill vs Spread and a new duplex service, Smart Connection rebalancing to keep hot updates on one node, and pre‑drain remastering for smooth re-configuration and a “last node standing” data‑only mode. Explains OCI options (Co‑Managed, Exadata Cloud Service on dedicated infra up to 32 nodes and 4 PB, Autonomous DB on RAC), ODA limits (2 nodes, 64 CPUs, 160 TB), and practical advice: create services, use Connection Manager, tune connect timeouts.
