DSC

The Dynamic System Configuration (DSC) program allows you to change the

configuration of X25AM and TLAM peripherals, controllers, and communication

processes interactively, without stopping the system. The user interface to DSC is the

Configuration Utility Program (COUP). You can use this tool to add X.25 and LAN

subnetwork lines to OSI/AS without having to bring your NonStop system down to

generate a new operating system image.

SCF

The Subsystem Control Facility (SCF), a Distributed Systems Management (DSM) tool,

allows you to configure the OSI/AS subsystem and the underlying OSI/TS subsystem.

In G-series releases, SCF is also used to configure the underlying X25AM controllers

and the PAM subsystem (for G06 and above releases). The OSI manager is used to add

and delete objects and to alter the characteristics of OSI/AS and OSI/TS interactively.

SCF also provides status and statistics information and tracing capabilities. For a

description of the general features, syntax, and semantics of SCF, see the Subsystem

Control Facility (SCF) Reference Manual (for D-series releases) or the SCF Reference

Manual for G-Series Releases. For a description of the OSI/AS-specific syntax and

semantics, see the OSI/AS SCF Reference Manual.

SCP

The Subsystem Control Point (SCP) is an intermediate process between SCF and the

OSI/AS subsystem. It provides security by restricting access to certain commands and

also provides tracing support for OSI/AS. SCP is opened automatically by SCF. For

more details about SCP, see the SCF Reference Manual for SCP and the Subsystem

Control Facility (SCF) Reference Manual (for D-series releases) or the SCF Reference

Manual for G-Series Releases.

EMS

The Event Management Service (EMS) provides event collection, event logging, and

event distribution facilities for OSI/AS and underlying subsystems. You can use this tool

to set up filters that select event messages of particular interest. Event messages issued

by the OSI/AS subsystem are described in Operator Messages: Distributed Systems

Management (DSM) Display Format, Operator Messages: Console Format, and the

OSI/AS Management Programming Manual.

PTrace

PTrace selects, formats, and displays trace data that has been gathered by the SCF

TRACE command. More detailed information on the PTrace displays for the OSI/AS

subsystem is in the OSI/AS SCF Reference Manual.
