Chapter 6 Managing Process Execution 163
ACTIVE When a client application accepts an offered activity or takes it off a
queue, it is placed in ACTIVE state. The engine performs any work
specified by an OnActive method in the process definition and then
provides the client application with process attribute data needed to
perform the activity. The client application is responsible for
performing the work associated with the activity. When the client
determines that the work is complete, it informs the engine, which
removes the activity from the session’s activity list and places the
activity in a COMPLETED state. When the client aborts the activity, it
informs the engine, which removes the activity from the session’s
activity list and places the activity in an ABORTED state.
COMPLETED The COMPLETED state signifies successful completion of an activity.
The engine performs any additional work specified by the
OnComplete method in the process definition, and then executes the
activity’s OnComplete router methods. Once any successor activities
specified in the routers are created, the engine deletes the
COMPLETED activity from memory.
ABORTED The ABORTED state signifies unsuccessful completion of an activity.
The engine performs any additional work specified by the OnAbort
method in the process definition, and then executes the activity’s
OnAbort router methods. Once any successor activities specified in
the routers are created, the engine deletes the ABORTED activity
from memory. If the process definition does not provide OnAbort
routers and the activity is aborted from ACTIVE state, the engine will
abort the process instance.
