The installation needs to know how you handle your structure when there are no active connectors to it. Console messages might require that an operator take some action against the structure, so it is important that the installation understands the structure's use.

A structure that you define as persistent will remain allocated in the coupling facility even when there are no active connectors to it. To delete a persistent structure from a coupling facility, the operator must issue a SETXCF FORCE,STRUCTURE command.
