Cache structures for VSAM sharing z/OS DFSMStvs Planning and Operating Guide SC23-6877-00 |
|
The coupling-facility cache structures provide a level of storage between local memory and DASD cache. They are also used as a system buffer pool for VSAM RLS data with cross-invalidation being done when data is modified on other systems. Each coupling-facility cache structure is contained in a single coupling facility. You might have multiple coupling facilities and multiple coupling-facility cache structures. |
