DSM/SCM Environment
Host System
From a host system, use the Planner Interface on the host system to perform these
tasks:

Transfer software files to target systems

Receive software into the DSM/SCM environment

Archive the software

Plan and create software revisions

Package and initiate the placement of software on distributed target systems
One host system can centrally control the configurations of many target systems or
several host systems can manage different systems in one site. If you maintain
separate development and production systems, you could use one host system for the
development systems and another host system for the production systems.
Target Systems
DSM/SCM also runs on each target system, where it places (applies) the software
received from the host system. Any system managed by DSM/SCM that is not a host
system is a target system. The host system includes its own target because the host
activates and manages the system software on itself.
Host and Target System Communication
A host system can be connected to a target system in one of three ways:

Network connected using Expand

Network connected without Expand (Transfer the files using either file transfer tools
or disk.)

Not network connected (Transfer the files to the remote system using magnetic
tape.)
When configuring the network connection between a host system and a target system,
use the REMOTEPASSWORD command to run the RPASSWRD program with which
you can establish passwords for the target system as needed. For more information,
see the Guardian User’s Guide.
Physical Targets
A physical target system (often referred to as target system) is any system managed
by DSM/SCM that is not the host system and to the physical target system on the host
system. A physical target system is defined with one or more logical targets.
