3.4.10. Configure an Attribute with the Management CLI

Summary

The write-attribute operation is a global operation used to write or modify a selected resource attribute. You can use the operation to make persistent changes and to modify the configuration settings of your managed server instances. The request properties include the following parameters.

Request Properties

name
The name of the attribute to set the value for under the selected resource.
value
The desired value of the attribute under the selected resource. May be null if the underlying model supports null values.

Procedure 3.23. Task

  • Run the write-attribute operation

    From the Management CLI, use the write-attribute operation to modify the value of a resource attribute. The operation can be run at the child node of the resource or at the root node of the Management CLI where the full resource path is specified.

Example 3.13. Disable the deployment scanner with the write-attribute operation

The following example uses the write-attribute operation to disable the deployment scanner. The operation is run from the root node, using tab completion to aid in populating the correct resource path.
[standalone@localhost:9999 /] /subsystem=deployment-scanner/scanner=default:write-attribute(name=scan-enabled,value=false)
{"outcome" => "success"}
The results of the operation can be confirmed directly with the read-attribute operation.
[standalone@localhost:9999 /] /subsystem=deployment-scanner/scanner=default:read-attribute(name=scan-enabled)
{
    "outcome" => "success",
    "result" => false
}
The results can also be confirmed by listing all of the node's available resource attributes with the read-resource operation. In the following example, this particular configuration shows the scan-enabled attribute is now set to false.
[standalone@localhost:9999 /] /subsystem=deployment-scanner/scanner=default:read-resource                                 
{
    "outcome" => "success",
    "result" => {
        "auto-deploy-exploded" => false,
        "auto-deploy-xml" => true,
        "auto-deploy-zipped" => true,
        "deployment-timeout" => 600,
        "path" => "deployments",
        "relative-to" => "jboss.server.base.dir",
        "scan-enabled" => false,
        "scan-interval" => 5000
    }
}
Result

The resource attribute is updated.
