+# google_oracle_database_db_nodes
+
+List all DbNodes of a Cloud VmCluster.
+
+For more information see the
+[API](https://cloud.google.com/oracle/database/docs/reference/rest/v1/projects.locations.cloudVmClusters.dbNodes).
+
+## Example Usage
+
+```hcl
+data "google_oracle_database_db_nodes" "my_db_nodes"{
+	location = "us-east4"
+	cloud_vm_cluster = "vmcluster-id"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `cloud_vm_cluster` - (Required) The ID of the VM Cluster.
+
+* `location` - (Required) The location of the resource.
+
+* `project` - (Optional) The project in which the resource belongs. If it
+    is not provided, the provider project is used.
+
+## Attributes reference
+
+The following attributes are exported:
+
+* `db_nodes` - List of dbNodes. Structure is [documented below](#nested_dbnodes).
+
+<a name="nested_dbnodes"></a> The `db_nodes` block supports:
+
+* `name` - The name of the database node resource in the following format: projects/{project}/locations/{location}/cloudVmClusters/{cloudVmCluster}/dbNodes/{db_node}
+
+* `properties` - Various properties of the database node. Structure is [documented below](#nested_properties).
+
+<a name="nested_properties"></a> The `properties` block supports:
+
+* `ocid`- OCID of database node.
+
+* `ocpu_count` - OCPU count per database node.
+
+* `memory_size_gb` - The allocated memory in GBs on the database node.
+
+* `db_node_storage_size_gb` - The allocated local node storage in GBs on the database node.
+
+* `db_server_ocid` - The OCID of the Database server associated with the database node.
+
+* `hostname` - The host name for the database node.
+
+* `state` - State of the database node.
+<a name="nested_states"></a>Possible values for `state` are:<br>
+`PROVISIONING` - Indicates that the resource is being provisioned.<br>
+`AVAILABLE` - Indicates that the resource is available.<br>
+`UPDATING` - Indicates that the resource is being updated.<br>
+`STOPPING` - Indicates that the resource is being stopped.<br>
+`STOPPED` - Indicates that the resource is stopped.<br>
+`STARTING` - Indicates that the resource is being started.<br>
+`TERMINATING` - Indicates that the resource is being terminated.<br>
+`TERMINATED` - Indicates that the resource is terminated.<br>
+`FAILED` - Indicates that the resource has failed.<br>
+
+* `total_cpu_core_count` - The total number of CPU cores reserved on the database node.
