NonStop System Glossary

start mode
An attribute of Subsystem Control Facility (SCF) PROCESS objects that controls when and if an
application process starts.
startup file
A file invoked by the local operator or by another startup file that contains commands to start up
system devices, communications lines, and system and application software. Contrast with shutdown
file.
state
In Subsystem Control Facility (SCF), one of the generally defined possible conditions of an object
with respect to the management of that object. Examples of states are DEFINED, STARTED, and
STOPPED.
static information
Information that represents the set of customer-replaceable units (CRUs) on a NonStop server.
Contrast with dynamic information.
static server
In the Guardian environment, a process that runs continuously and provides a specific service to
other processes. A static server differs from a traditional UNIX demon in that a demon actively
looks for tasks to perform. A static server performs only tasks brought to its attention by a client
(requestor) process. See also demon.
static translation
A TNS translation step explicitly invoked from the command line before a TNS object file is executed.
The Accelerator and the TNS Object Code Accelerator (OCA) are static translators.
STFs
See super time factors (STFs).
storage pool
A set of physical disk volumes administered as a set of logical disk volumes. A logical disk volume
can span multiple physical disk volumes. When a logical disk volume becomes full, more physical
disk volumes can be added.
storage subsystem
A subsystem of the NonStop operating system that handles configuration and management of disk
and tape devices.
storage subsystem manager process
The generic process that starts and manages disk and tape drives. The $ZZSTO storage subsystem
manager process is started and managed by the $ZZKRN Kernel subsystem manager process
through the $ZPM persistence manager process.
storage-pool file
A file containing a list of disk volumes to be used by an Open System Services (OSS) fileset. As
these volumes are filled, more volumes can be added to the storage-pool file.
