psm dhcs scale-in -s|--service-name cluster-name

	[-of|--output-format short|json|html]
	[-wc|--wait-until-complete true|false]

Parameters

Parameter Description

-s|--service-name cluster-name

Specifies the name of the Oracle Data Hub Cloud Service cluster.

-c|--config-payload path-to-json-file

Specifies the path to a JSON file containing the information necessary to scale in a cluster. The format of this file is the same as the request body you provide when scaling in a service instance by using the REST API. For information about this format, see the “Body Parameter” section of Scale In a Service Instance in REST API for Oracle Data Hub Cloud Service.

-of|--output-format short|json|html

(Optional) Specifies the output format of the command’s response:

  • short— output is formatted as a brief summary.

  • json— output is formatted as a JSON array.

  • html— output is formatted as HTML

The default output format is the one you specified when using the psm setup command to configure the psm CLI.

–wc|--wait-until-complete true|false

(Optional) If set to true, the command behaves synchronously. That is, it does not return until the submitted job is complete. The following message is displayed until the job is complete:

Waiting for the job to complete... (it cannot be cancelled)

The default value is false.

Examples

The following example removes the node cluster1-cass-2 and scales-in the cluster1 cluster.

$ psm dhcs scale-in -s cluster1 -c remove-dhcs-2.json

        "jobId":"7126059"
    }
