首页 > Term: VSAM record-level sharing (VSAM RLS)
An extension to the Virtual Storage Access Method (VSAM) that provides direct record-level sharing of VSAM data sets from multiple address spaces across multiple systems. Record-level sharing uses the z/OS Coupling Facility (CF) to provide cross-system locking, local buffer invalidation, and cross-system data caching. Contrast with global shared resources and local shared resources. See also SMSVSAM, global shared resource, local shared resource.
