What are the RAC/Grid specific daemons in Oracle 12c

CRSD (Cluster Ready Service Daemon):


CRSD is primarily responsible for maintaining the availability of the application resources such as DB instances. Main responsibility of the CRSD daemon is starting and stopping of the resources, relocating the resources when required to another node in the event of failure and updating the resource profiles in the OCR file and also responsible for backing up the OCR file.
