The crsctl utility is used to invoke certain OHASD functions.
To check the viability of Cluster Synchronization Services (CSS) across nodes:
- To stop Oracle High Availability Services:
- Stop the Clusterware stack:
- # crsctl stop cluster
- Stop Oracle High Availability Services on the local server:
- # crsctl stop crs
- To display Oracle High Availability Services automatic startup configuration:
- # crsctl config crs
If you intend to stop Oracle Clusterware on all or a list of
nodes, then use the crsctl stop
cluster command, because it prevents certain
resources from being relocated to other servers in the cluster before the
Oracle Clusterware stack is stopped on a particular server. If you must stop
the Oracle High Availability Services on one or more nodes, then wait until the
crsctl stop cluster command completes and then run the crsctl stop crs command on any particular nodes, as
necessary.
Use the crsctl config
crs command to display Oracle High
Availability Services automatic startup configuration.
To determine the overall health on a specific node:
