DSM/SCM

The Distributed Systems Management/Software Configuration Manager (DSM/SCM) is

a system for the centralized planning, management, and installation of software on

distributed NonStop S-series systems and Integrity NonStop NS-series systems.

DSM/SCM performs the activities associated with installing and managing software

revisions.

NonStop Kernel Subsystem

On NonStop S-series servers and on Integrity NonStop NS-series servers, the

NonStop Kernel subsystem configures, starts, and stops a QIOMON process. A

configuration file can optionally be specified when starting the QIOMON process. For

more information about the NonStop Kernel subsystem, see the SCF Reference

Manual for the Kernel Subsystem.

Event Management Service (EMS)

EMS provides event-collection, logging, and distribution facilities. The QIO subsystem

reports events to EMS, as illustrated in Figure 1-2 on page 1-8. Operators and

applications can retrieve these event messages from EMS. EMS lets each operator or

application specify filters that determine the event messages received. EMS supports

network analysis, problem determination, and remote operations.

Event messages are sent directly from the subsystem to the EMS event collector ($0).

You can select (filter) the types of event messages to be displayed, printed, or stored.

For more information, see the DSM/SCM User’s Guide and the EMS Reference

Summary.

Note. The Subsystem Programmatic Interface (SPI) is not supported externally for the QIO subsystem.
