Monitoring and Managing Process Execution

As described in “Process Execution” on page 165, an iIS process engine executes process instances by creating a succession of activities, moving them through a number of states, checking timers, and locking, modifying, and unlocking process attributes.

For each process instance, it maintains information about activities, timers, and process attributes (and locks placed on each process attribute). The information provided about these objects and their relationship to one another are illustrated in Figure 6-2:
