Automatic vary off and deletion of controller descriptions

The automatic vary off and delete function is controlled by the AUTODLTCTL parameter in the line description. When a controller description that specifies CTLOWN(*SYS) is varied on manually or automatically:

• The system copies the current value of the AUTODLTCTL parameter associated with the controller description.
• When a controller goes to a vary on pending status, a timer based on the AUTODLTCTL parameter is started. If this controller remains in a vary on pending status, and it is not varied off manually by the operator for the entire time specified by the AUTODLTCTL parameter, then the system automatically varies off and deletes the controller description and all of its attached APPN device descriptions.
