After you make changes to the configuration parameters, you must restart the agent in order to bring into effect the configuration changes. You can use the Restart Agent option from the Agents view. You can also use the option to restart the agent service.
When you restart the agent service, it terminates any jobs that are running on the agent.
To restart the agent
Go to Manage > Asset System > Agents.
Select an agent in the table pane and click Restart Agent from the Agent Tasks on the taskbar.
