object-name template.
object-name template. A name that stands for more than one Subsystem Control Facility
(SCF) object. Such a name includes one or more wild-card characters, such as *
(asterisk) and ? (question mark). See also wild-card character.
object type. The category of Subsystem Control Facility (SCF) objects to which a specific
SCF object belongs. For example, a specific disk has the object type DISK, and a
specific terminal can have the object type SU. Each subsystem has a set of object
types for the objects it manages.
obsolescent. An indication that a feature or facility exists for compatibility with older
versions or drafts of a standard. Obsolescent features or facilities should not be used
because they might be removed from future versions of a standard and therefore might
not be portable.
offline. (1) Used to describe tasks that are performed outside of the control of an application
or computer system. (2) Used to describe tasks that require system resources to be
shut down. Contrast with online.
offline change. Any change that requires system resources to be shut down. Offline
changes are usually performed during a planned outage. Contrast with online change.
offline configuration. Configuration performed offline by Distributed Systems
Management/Software Configuration Manager (DSM/SCM). If necessary, you edit the
CONFTEXT configuration file to create a new configuration and then run DSM/SCM to
generate a system image for the new configuration.
ohm. The standard unit for measuring resistance. A one-ohm resistor will conduct one
ampere when one volt is applied.
online. Used to describe tasks that can be performed while the HP NonStop™ operating
system and system utilities are operational. Contrast with offline.
online change. Any change that can be performed while an application or its system
resources are operational. In some situations, online changes might temporarily affect
subsystem and application availability. For example, altering the characteristics of a
communications line might temporarily affect applications that use the communications
line. Contrast with offline change.
Online Support Center (OSC). The group of support specialists within the HP Global
Customer Support Center (GCSC) who respond to telephone calls regarding system
problems and diagnose malfunctioning systems using remote diagnostic links.
open file. In the Open System Services (OSS) file system, a file with a file descriptor.
open file description. In the Open System Services (OSS) file system, a data structure
within an HP NonStop™ Expand node that contains information about the access of a
process or of a group of processes to a file. An open file description records such
attributes as the file offset, file status, and file access modes. An open file description
