ASSIGN
ASSIGN. An HP Tandem Advanced Command Language (TACL) command you can use to
associate a file name with a logical file of a program or to assign a physical device to
logical entities that an application uses.
assign message. Within Subsystem Control Facility (SCF), a message created by SCF for
each ASSIGN command. A new process must request its assign message following
receipt of the startup message. All assign messages set by the SCF ASSIGN
command, plus the ones read from the HP Tandem Advanced Command Language
(TACL) command interpreter, are passed to the new process.
assumed object. The object type or object name specified by a Subsystem Control Facility
(SCF) ASSUME command. If an ASSUME command has been used to establish a
default object type and fully qualified default object name, and if that object type and
object name together refer to a valid object,
object-spec can be omitted entirely
from an SCF command, and the command is applied to the object known as the
assumed object.
asynchronous wide area network (AWAN) servers. A local area network (LAN)-based
communications device that provides (1) asynchronous connections to terminals,
printers, and terminal emulators for HP NonStop S-series and K-series servers; (2)
remote-access disk operating system (DOS), Windows, and Macintosh platforms; (3)
VT-to-6530 protocol conversion; and (4) dial-out connections for LAN-attached DOS,
Windows, and Macintosh platforms.
ATM3SA. See ATM 3 ServerNet adapter (ATM3SA).
ATM 3 ServerNet adapter (ATM3SA). A ServerNet adapter that provides access to
Asynchronous Transfer Mode (ATM) networks from an HP NonStop™ S-series server.
The 3860 ATM3SA supports the ATM User-Network Interface (UNI) specification over
a 155-megabit/second (Mbps) OC-3 Sonet (Synchronous Optical Network) connection.
atomic. Behaving as a single, indivisible operation. For example, an atomic write operation
on a file cannot write data that is interleaved with data from another, concurrent write
operation on that file.
attachment. A file that contains information that augments the information in an incident
report.
attribute. (1) For the Subsystem Control Facility (SCF), a characteristic of an entity. For
example, two attributes of a process might be its program file and its user ID. An
attribute is sometimes called a modifier. (2) In OSM and TSM client interfaces, a data
item associated with a system or cluster resource. All attributes can be viewed, and
some can be modified.
audit. A Distributed Systems Management/Software Configuration Manager (DSM/SCM)
activity initiated by the operator at a target system that updates the target database
with the fingerprints of all the files in a selected set of target subvolumes (TSVs).
