This example shows how to modify the *wlm_json_configuration* parameter for workload management.

Command::

   aws redshift modify-cluster-parameter-group --parameter-group-name myclusterparametergroup --parameters '{"parameter_name":"wlm_json_configuration","parameter_value":"\[{\\"user_group\\":\[\\"example_user_group1\\"],\\"query_group\\":\[\\"example_query_group1\\"],\\"query_concurrency\\":7},{\\"query_concurrency\\":5}]"}'

Result::

    {
       "ParameterGroupStatus": "Your parameter group has been updated but changes won't get applied until you reboot the associated Clusters.",
       "ParameterGroupName": "myclusterparametergroup",
       "ResponseMetadata": {
          "RequestId": "09974cc0-64cd-11e2-bea9-49e0ce183f07"
