Oracle Real Application Cluster

Oracle Real Application Clusters (RAC) on Oracle Exadata Database Machine provides active-active database availability and elastic scale by running multiple Oracle instances against a single database. Oracle Exadata Info by Jasmine evaluates your HA/DR objectives, SLA targets, and failure domains, then designs an Exadata-optimized RAC topology (node count, interconnect, voting/OCR layout, SCAN/VIP strategy, and service-based workload placement). We validate cluster health, networking latency, load balancing, and failover behavior, and tune services to isolate workloads, reduce planned downtime, and maintain predictable performance during peaks and node outages.
