Structures, dump space, and coupling facility LP storage
A coupling facility allocates storage for structures and for dump space based on values specified in the SIZE, INITSIZE, and DUMPSPACE parameters of the coupling facility resource management (CFRM) policy used for the coupling facility.
Structures consist of control objects and data elements. The control objects include entries and various other control structures used to manipulate the entries. The data elements store user data associated with structure entries.
Dump space is storage in the coupling facility set aside for use as a dump table when a structure dump is taken. Dump tables are used for application development and problem determination purposes.
