Enscribe and NonStop SQL/MP file types; creates TMF audit trail records; performs
logical REDO operations for Remote Duplicate Database Facility (RDF); and manages
disk space, disk controllers, and paths to the disks. This disk process provides
enhanced performance, throughput, recoverability, and reliability improvements in high-
volume, online transaction processing situations.
Distributed Systems Management/Software Configuration Manager (DSM/SCM). A
GUI-based program that installs new software and creates a new operating system.
DSM/SCM creates a new software revision and activates the new software on the
