DSECT NAME - SYTSHS
FUNCTION - Map a Monitor record.
LOCATED BY -
Through the Monitor Control Area
REFERENCED CONTROL BLOCKS -
MRRECHDR Monitor Record Header
NAME - MRSYTSHS
DESCRIPTIVE NAME - Monitor Sample Record
Domain 0 - System Domain
Record 7 - Shared Storage Data
DESCRIPTION - Named Saved System(NSS), Discontiguous saved
segment(DCSS) and Shared Address Spaces
management.
Virtual disk in storage information is also
included in this record since the disk is
supported by storage, not DASD.

A value of -1 indicates that
there is no limit.

This includes 1 for each
virtual disk in storage
created with the define
command.

disks in storage. "Active"
being a disk that is
currently linked by at least
one user.
