If a child activity fails, it may be appropriate to retry it. The parent
should (if it has not already done so) issue a CHECK ACTIVITY command to check
the current completion status of the child activity.
To retry a child activity that has failed:
- Issue a RESET ACTIVITY command. The child activity is reset to its initial
state: its completion event is added to the parent’s event pool, with
the status set to NOTFIRED; any children of the child activity are deleted.
Note that the child activity’s data-containers are not disturbed.
- Issue a RUN ACTIVITY command. The child activity is invoked with a DFHINITIAL
event.
