CRSCTL Overview

CRSCTL is an interface between you and Oracle Clusterware, parsing and calling Oracle Clusterware APIs for Oracle Clusterware objects.

Oracle Clusterware 11g release 2 (11.2) introduces cluster-aware commands with which you can perform check, start, and stop operations on the cluster. You can run these commands from any node in the cluster on another node in the cluster, or on all nodes in the cluster, depending on the operation.

You can use CRSCTL commands to perform several operations on Oracle Clusterware, such as:

Starting and stopping Oracle Clusterware resources

Enabling and disabling Oracle Clusterware daemons

Checking the health of the cluster

Managing resources that represent third-party applications

Integrating Intelligent Platform Management Interface (IPMI) with Oracle Clusterware to provide failure isolation support and to ensure cluster integrity

Debugging Oracle Clusterware components

Overview of SRVCTL

Use SRVCTL to manage configuration information. You can use SRVCTL commands to add, remove, start, stop, modify, enable, and disable a number of entities, such as databases, instances, listeners, SCAN listeners, services, grid naming service (GNS), and Oracle ASM.

Some SRVCTL operations modify the configuration data stored 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.
