Using Oracle Enterprise Manager (OEM): Log in to the OEM console, select the “Cluster” tab, and then choose “Display Cluster Status” to view the cluster status.
To utilize the Clusterware command line tool, log in to the command line interface of the cluster node and use the command “crsctl check cluster -all” to check the cluster status.
Utilize cluster management tools: If you are using cluster management tools like Oracle Grid Infrastructure (GI) or Oracle Real Application Clusters (RAC), you can use the relevant commands or interface to check the status of the cluster.
Use SQL query to check the cluster status by logging into the database instance and executing the following query statement in SQL*Plus or SQL Developer.

SELECT NAME, VALUE FROM V$CLUSTER_ACTIVE_INSTANCES;
