The CRSCTL – CRS Oracle (Cluster Ready Service Control) commands perform some cluster control operations, with which it is possible to execute control, start, and stop operations on the cluster.
These commands can be executed from any node in the cluster on another node or on all nodes in the cluster, depending on the operation.
The operations that the CRSCTL command allows are:
Starting and stopping Oracle Clusterware resources Enabling and disabling Oracle Clusterware daemons Checking the status of the cluster Managing resources that represent third-party applications Integrating Intelligent Platform Management Interface (IPMI) with Oracle Clusterware to provide support for fault isolation and to ensure cluster integrity Debugging Oracle Clusterware components
In the CRSCTL Commands – Oracle CRS category, we provide the most commonly used operations with the CRSCTL command.
CRS START ALL With the CRS START ALL article: Complete startup of all CRS cluster resources, we provide the command to initiate the opening of all online resources registered in the CRS, including the opening of databases, by executing the command from a node of an RAC. If the first Read more…

In this post, we’ll discuss how to enable CRS, so welcome to the “Enable CRS” article, where we provide the command to enable CRS upon operating system reboot. To enable CRS, only one command is needed, but make sure to type it correctly. For this purpose, we suggest using the Read more…
Disable CRS With the article “Disable CRS,” we provide the command to disable CRS upon operating system reboot to disable autostart. The command is just one, but we advise executing it with caution, as with any command on server platforms, of course. Disabling CRS disables CRS on the system and Read more…
With the article CRS start, we provide the command to perform a complete start of the CRS along with all its related resources. In the event that the RAC node has undergone maintenance activities or a change in some hardware component, and the CRS has been previously shut down and Read more…
With the article CRS stop, we provide the command to perform a complete stop of the CRS. The command provided is very convenient, as it shuts down all resources present on the node where it is executed. Complete CRS shutdown is very convenient because there is no need to first Read more…
