You need to select the region where the parameter is located, parameter name, and parameter association mode from Creating a Parameter.

   If you select parameter warehouse, you need to create the parameters to be selected on the Parameter Management > Parameter Center page.

4. Enter the execution user and execution timeout interval. Executed by: the user who executes the script on the target instance node. The default user is root. Timeout Interval: the timeout interval for executing the script on a single instance. The default value is 300.
