Explanation

• CRSCTL is an interface between you and Oracle Clusterware, parsing and calling Oracle Clusterware APIs for Oracle Clusterware objects. * CSS- Cluster Synchronization Services - a daemon process that is used for synchronization between different RAC nodes and synchronization between ASM and Oracle database instances. * CRS - Oracle Clusterware is run by Cluster Ready Services (CRS) D: SRVCTL Node-Level Tasks The node-level tasks are: Adding and deleting node level applications. Setting and unsetting the environment for node-level applications. Administering node applications. Administering ASM instances. Starting and stopping a group of programs that includes virtual IP addresses, Listeners, Oracle Notification Services, and Oracle Enterprise Manager agents (for maintenance purposes). Note: The Server Control (SRVCTL) utility is installed on each node by default. You can use SRVCTL to start and stop the database and instances, manage configuration information, and to move or remove instances and services. You can also use SRVCTL to add services. SRVCTL also manages configuration information. Some SRVCTL operations store configuration information in the Oracle Cluster Registry (OCR). SRVCTL performs other operations, such as starting and stopping instances, by sending requests to the Oracle Clusterware process (CRSD), which then starts or stops the Oracle Clusterware resources. * OCR - Oracle Cluster Registry
