disable

Disables a specified object (cluster database, database instance, Oracle ASM instance, or service). Use the srvctl disable command when you must shut down an object for maintenance. The disabled object does not automatically restart.

When you run the disable command, the object is disabled and unavailable to run under Oracle Clusterware for automatic startup, failover, or restart. Additionally, you cannot run the srvctl start command on a disabled object until you first re-enable the object. If you specify -instance instance_name or -node node_name, then SRVCTL only disables the object on the specified instance or node.

If you do not specify -instance instance_name or -node node_name, then the disable action applies to the object that you specified, globally, on all nodes in the cluster and also supersedes any per-node disable settings. Any object you disable globally is also disabled on any nodes you add to the cluster in the future.

Disabling an object globally is different from disabling an object, individually, on each node in the cluster. For example, if you disable a database on several nodes, individually, in a cluster, then, when you run the srvctl start database command, the database starts only on nodes where the database is enabled. If, however, you disable the database globally, then the srvctl start database command is rejected because the database is disabled, clusterwide.
