Resources such as database services, ASM instances, RAC databases, database services, listeners, ASM disk groups and VIP addresses are called Cluster ready services (CRS). And the status and cluster configuration information of these resources are stored in OCR (Oracle Clusterware Registry) shared storage and are used by oracle clusterware to manage them.
We can use CRSCTL command to check the status of the resources. And to manage each individual resource we can also use the SRVCTL command.
