Cache Fusion
The Oracle RAC mechanism that transfers current or consistent database blocks between instance buffer caches over the private interconnect.
Oracle Runtime Context
Cache Fusion avoids forcing every shared-block transfer through disk, but hot blocks can create global-cache contention and interconnect pressure. RAC scalability therefore depends on access locality, block ownership patterns, service placement, and workload partitioning.
