TS/MP 2.5 Release Supplement

process broker (PB)
process
A process that executes in each processor within a system to manage the resources and link
reservations for the processor.
NOTE: The PB is part of the ACS Subsystem.
product module A process that resides in each ACS subsystem for communicating with SCF. The product module
is responsible for subsystem-specific command processing.
Q-R
redirector (RD)
process
Processes that provide link management functionality to Pathsend requestors.
requestor A process that uses the Pathsend API to communicate with server class processes. This is also
called the client process.
ROUT redirector (RD) processes that provide LINKMON like functionality to Pathsend requestors. They
are also referred to as RD processes.
NOTE: The RD is part of the ACS Subsystem.
S-Z
sensitive command A command that can be issued only by a restricted set of Guardian users, for example the owner
of the subsystem process or a member of the supergroup. Sensitive commands can change the
state of the configuration of objects. See also non-sensitive command.
Subsystem Control
Facility (SCF)
A common interactive management interface for configuring, controlling and collecting information
from subsystems.
Subsystem Control
Point (SCP)
The management process for a number of subsystems. There can be several instances of this
process. Applications using SPI send the commands for a subsystem to an instance of the SCP,
which in turn sends the command on to the manager process of the targeted subsystem (which
is $ZACS for ACS subsystems).
subsystem
manager process
In DSM, a NonStop server subsystem process that the SCP process uses to communicate with the
subsystem. The ACS subsystem manager process is the domain coordinator, $ZACS.
Subsystem
Programmatic
Interface (SPI)
A set of NonStop operating system procedures, message formats, and definition files that allows
management commands and applications to communicate directly with subsystem processes,
such as the TS/MP PATHMON process and the ACS subsystem link management processes, for
configuration and control of objects and for event management.
