Stopping a LINE Object

To make changes to the LINE object, first stop or abort the line, then change it and

restart it. The following example shows how to stop a line by issuing an SCF

command:

-> STOP LINE $EXF01

Changing a LINE Object

You can change line attributes by issuing SCF commands directly to the EnvoyACP/XF

subsystem. These changes persist until you stop the DEVICE (in the WAN subsystem)

associated with the line, until after a system load or processor reload, or until an

application procedure call overrides the attributes.

The following example shows how to change a line’s attributes directly through the

EnvoyACP/XF subsystem:

> SCF

-> ALTER LINE $EXF01

, ABMSETP ON

Starting a LINE Object

To start the line after you have changed it, issue the SCF START command to the

EnvoyACP/XF subsystem as in the following example:

> SCF

-> START LINE $EXF01

DSM and SCF Basics

This subsection gives you a brief introduction to Distributed Systems Management

(DSM) and to SCF. If you need more information than is provided here, see the

DSM/SCM User’s Guide. If you are already familiar with DSM and SCF, you can

proceed to NonStop S-Series Servers, Integrity NonStop NS-Series Servers, and

EnvoyACP/XF on page 4-7.

The DSM product supports integrated management of system and network resources

and operations. DSM architecture consists of the following:

•

An operations environment providing applications and tools for operations tasks

and for controlling the subsystems

•

A subsystem environment in which subsystems (such as EnvoyACP/XF) and the

objects they control are managed (by the tools and applications in the operations

environment)

•

A set of management services that support the programmatic interface between

the subsystem and operations environments
