Hi Michel, as we are working together on this a quick addition : the ESS present in every domain in the architecture schematic is the Enterprise Scheduler Service. Quoting from the concepts guide :
“Oracle Enterprise Scheduler provides the ability to define, schedule, and run different types of jobs. You can run jobs on demand, or schedule them to run in the future.
Oracle Enterprise Scheduler provides scheduling services for the following purposes:
To distribute job request processing across a grid of application servers
To run Java, PL/SQL, spawned jobs, binary processes, and Oracle Business Intelligence Publisher reports
To process multiple jobs concurrently
To schedule job requests to run a single time in the future, on a recurring basis, or based on triggering events
To run the same job in different languages
Oracle Enterprise Manager Fusion Applications Control (Fusion Applications Control) enables you to start and stop, monitor, configure, and manage Oracle Enterprise Scheduler services, components, and job requests.”
