SIT
SIT. See system image tape (SIT).
site ID. A unique 6-digit number assigned by HP to identify a particular system.
site-specific subvolume. A subvolume containing files unique to the target system, such
as a list of products belonging to the target. Its format is Annnnnn, where nnnnnn is
the system site ID.
site update tape (SUT). One or more tapes that contain a target system’s site-specific
subvolume and various products. Each product contains a softdoc and a complete set
of files. A SUT is delivered with every new NonStop system and can be ordered
whenever a new RVU of the system software is available. A full SUT contains the
current RVU of the operating system and all product software that has been ordered
with it, including release documentation.
snapshot. A list of the target system tape and disk locations, file fingerprints for files
managed by DSM/SCM, and DSM/SCM target information. It is compiled on the target
system from the target database and sent to the host system to store in the host
database. It contains information about the software running on the target system and
the products placed on the target by the most recent revision. An instruction to create a
snapshot is part of every activation package sent from the host and can also be
requested independently through the Target Interface (ZPHITI).
softdoc. A software document provided with each NonStop product that describes new
features, corrected problems, and remaining known problems. The softdoc also gives
the product name and number; the required hardware, firmware, and software; and the
names of supporting manuals.
software input. A collection of one or more products received by DSM/SCM into the
archive. The products can be either HP software (an RVU, SPR, or new PVU) or
software from a third-party vendor or customer.
software product revision (SPR). The HP method of releasing incremental software
updates for the NonStop operating system. An SPR is one or more files that contain
one or more fixes to NonStop code. It can also contain code that adds new functions to
a NonStop software product. An SPR is identified by a three-letter code attached to the
product number; for example, T9050AAB.
software release. See
release version update (RVU).
software revision. See revision.
SPI definitions. Subsystem Programmatic Interface files that are included in programs,
macros, and routines using the interface procedures; and definition files in data
definition language (DDL) for programmers writing their own subsystems.
SPR. See software product revision (SPR).
