Which three statements are true about the background Workflow Engines that are set up as a
required component while setting up Oracle Workflow? (Choose three.)
A.
It handles stuck processes.
B.
It handles deferred activities.
C.
It handles timed outnotifications.
D.
It cleans up the WF_CONTROLqueue.
E.
Ithandles listeners forlocal outbound agents.
Explanation:
A:Abackground engine must be set up to handle stuck processes. A process is
identified as stuck when it has a status of ACTIVE, but cannot progress any further.
B: When the Workflow Engine initiates and performs a process, it completes all necessary
activities before continuing to the next eligible activity. In some cases, an activity can require a
large amount of processing resource or time to complete. Oracle Workflow lets you manage the
load on the Workflow Engine by setting up supplemental engines to run these costly activities as
background tasks. In these cases, the costly activity is deferred by the Workflow Engine and run
later by a background engine. The main Workflow Engine can then continue to the next available
activity, which may occur on some other parallel branch of the process. A workflow process can
also include a Wait activity, which defers the continuation of a process until a later time. This type
of deferred activity is also completed by a background engine.
C:A background engine must also be set up to handle timed out notification activities.
