All kernel tasks are maintained on the page of the menu (http://YourGateway:8080/sapr3gateway/manager/run). For information about the SAP R/3 Gateway GUI and how to use System Manager, see the section System Manager.
The following figure illustrates the page. The first column shows the instance of a Running Task. The link points to parameters of an
The tasks can be started and stopped with the button in the Operation column. The stop command cancels the task at the operating-system level. The start command starts a process as a child of this Application Server. The button is toggled between start/stop commands.
There are 3 startup types (the Startup column):
| attach | There is no controller for starting and stopping. |
| manual | This task must be started by the user. If this task terminates abnormally, it will restart automatically. |
| auto | This task is started automatically when this Application Server is booted. If this task terminates abnormally, it will restart automatically. |
To display more information about the parameters of a Running Task, you can choose the link in the first column.

A and a command are available for some tasks. These buttons are only available if the configuration of a task defines the shutdown command.
| Shutdown | The defined shutdown command is executed and the Task Controller is disabled. |
| Restart | The defined shutdown command is executed and the Task Controller is unchanged. Therefore, if the startup type is set to "manual" or "auto", the task will be started immediately. This feature can be used when changing parameters. Please check the associated Start-at time. |
In general, it is possible to disable the Task Controller for all running tasks. This is necessary if you want to stop all tasks for a period using an Operating System command or other tool. In this case, the autostart is inactive. Please do not forget to enable the Task Controller.
For more detailed information on the configuration of runnings tasks, refer to the section Running Tasks under the heading "Workers".
