asynchronous wide area network (AWAN) servers
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 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 system
enclosure. 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).
authentication attributes. Security attributes of a process that do not change unless a
successful reauthentication occurs or the super ID changes them. For Open System
Services (OSS) processes, the authentication attributes include the login name, real
user ID, real group ID, authentication system (node name), and group list.
authorization attributes. Security attributes of a process that can change through use of
functions such as
setuid() (or of Guardian procedures such as
PROCESS_CREATE_) without reauthentication. For Open System Services (OSS)
processes, the authorization attributes include the effective user ID, saved-set user ID,
saved-set group ID, user audit flags, and effective user name.
