Description

The XRF ZCP tracking queue organizer allows pending XRF tracking activity to be stored in a way that honors interdependencies, while allowing such requests to be met as soon as all their prerequisites are fulfilled. This component consists of a data structure and accessing program that uses the CICS catalog key structure to identify all the actions for a single resource and the dependencies between them. Actions are put into the structure on receipt in DFHTCRP, and removed by DFHTCRP and at the end of DFHZNAC processing for standby BIND and CLSDST completion. The structure is freed at the end of DFHTCRP tracking.
