Indicates whether or not the ordering of coupling facilities in the preference list will be strictly enforced when the structure is allocated. Using this option can help ensure structure availability when the coupling facility and the systems in the sysplex reside on the same processor.
Specify No when you want the system to reorder the list of coupling facilities in the preference list to choose the coupling facility that most closely fits the application's requirements.
Specify Yes when you do not want the system to reorder the list of coupling facilities in the preference list. The system might choose a coupling facility based on its order in the list rather than on how well it satisfies the structure allocation requirements. If you specify Yes for Enforce order of preference list, the system ignores the exclusion list.
