Veritas Cluster Server inter-process communication
To coordinate access to a single database by multiple instances, Oracle uses extensive communications between nodes and instances. Oracle uses Inter-Process Communications (VCSIPC) for Global Enqueue Service locking traffic and Global Cache Service cache fusion. SF Oracle RAC uses LLT to support VCSIPC in a cluster and leverages its high-performance and fault-resilient capabilities.
Oracle has an API for VCSIPC, System Kernel Generic Interface Inter-Process Communications (skgxp), that isolates Oracle from the underlying transport mechanism. As Oracle conducts communication between processes, it does not need to know how data moves between systems; the cluster implementer can create the highest performance for internode communications without Oracle reconfiguration.
