Components must work together to complete a service request
successfully.
Figure 1. Components running a service

This diagram shows how components work together to run a service:
- The application server administrator starts the management server
and the manager, and the administrator of the proxy computer starts
the proxy. The management server, the proxy, and the manager are designed
to run continuously.
- An operator uses the manager to run or schedule a service.
- The manager sends the service request to the management server
to which the service is assigned.
- The management server forwards the service request to the proxy
to which the service is assigned.
- The proxy starts the service by using the component specified
in the service. For services that the executor runs, the proxy starts
an instance of the executor to process the service request. For services
that another component runs, the proxy passes the service request
to that component.
- The executor or the other service execution component runs the
service.
- The service performs the tasks in its service plan.
- For services that are run by the executor, the proxy continuously
monitors the executor while the executor runs the service.
- When the service is complete, the executor or the component that
ran the service returns the service request status to the proxy. The
executor instance also closes itself.
- The proxy returns the service request status to the management
server and the manager.
