Click the Custom Templates tab, find the new template DescribeInstances, and then click Create Execution in the Actions column.
On the Create Execution page that appears, set the parameters in the Basic Information section.
In this example, set Execution Mode to Automatic. The following table describes the parameters.

Click Next: Parameter Settings. On the page that appears, set the parameters and confirm the permissions of the RAM role.
In this example, set Status to Stopped.
To ensure that the template can be successfully executed, follow these steps to check the authorization policies of the RAM role that OOS will use:
Click View Authorization Policies. Then, log on to the RAM console. Verify that the RAM role to be used by OOS exists and that this RAM role has the permissions required for template execution. That is, the permissions of this role are not fewer than the result of View Authorization Policies. If the RAM role to be used by OOS is not created, or this role is created but is not granted the permissions required for template execution, click Automatic Authorization. You can also click Manual Authorization, and grant the required permissions to the role. For more information, see Configure RAM permissions for OOS.
Click Next: Preview.
Click Create Execution.
On the Executions tab, view the execution result.
If you set the execution mode to Automatic, the template will be automatically executed. After the execution is completed, the execution status becomes Success.
If you set the execution mode to Manual or set the risk confirmation mode to Require Confirmation for High-risk Tasks, you need to manually execute the template.
To view the execution details, click the execution ID or click Details in the Actions column.
