VCSIPC VCS Cluster Inter-Process Communication

VCSIPC defines the protocols and interfaces required for the RAC environment to transfer messages between instances. RAC Inter-Process Communications uses the VCSIPC shared library for interprocess communication. In turn, VCSIPC uses LMX, an LLT multiplexer, to provide fast data transfer between Oracle processes on different cluster nodes.
