DSECT NAME - STOSHR FUNCTION - Map a Monitor record. LOCATED BY - Through the Monitor Control Area REFERENCED CONTROL BLOCKS - MRRECHDR Monitor Record Header NAME - MRSTOSHR DESCRIPTIVE NAME - Monitor Sample Record Domain 3 - Storage Domain Record 3 - Shared Storage Management (per NSS or DCSS) DESCRIPTION - Describes shared storage use for Named Saved Systems (NSSs), Discontiguous Saved Segments, (DCSSs), and Segment Spaces (SSPs). A separate record is generated for each active saved system/segment.
