Managing orphaned activities

Orphaned activities are child elements that do not have a parent element. This is an
unexpected condition and would usually indicate that an error had occurred during
configuration of the batch or procedural operation. It is important to deal with orphaned
activities however, as they consume resources in the Server and the Controller and could
potentially prevent another batch or procedural operation from proceeding.
You will be alerted to the existence of orphaned activities by a system alarm raised on the
server system point. The alarm will return to normal when there are no more orphan activities
in the system.
To manage an orphaned activity
1. From the Alarm Summary, double click the alarm indicating the existence of the
orphan activity to display the Orphan Activity Summary display, which lists all
orphan activities in the system.
2. Select an orphan activity from the list and click F12 to navigate to the Activity Detail
display for that activity.
From here, you have access to all the usual activity options so you can command the
batch or procedure as you would any other activity.
