might have the object type SU (subdevice). A subsystem identifies a set of object
types for the objects it manages. The SCF interfaces to NonStop data communications
subsystems use standard keywords to identify the types. The corresponding
programmatic interfaces have object-type numbers (represented by symbolic names
such as ZCOM-OBJ-SU) suitable for passing to the SPI SSINIT procedure.
In the GPI, a category of objects having a common purpose and structure is called a
“class.”
octet. A sequence of eight bits. Also called a “byte” or “character.”
octet string. A string comprising octets.
open system. A computer system based on standard technologies: for example, one that
adheres to the OSI standards.
originator. The person or application that prepares and submits messages for delivery
through an X.400 message handling system.
O/R (originator/recipient) address. A list of attributes that describes a user and locates
that user in relation to the physical or organizational structure of the MHS or the
underlying network. An O/R address, which is part of the O/R name, provides routing
information for an X.400 message handling system.
O/R (originator/recipient) name. A list of attributes that identifies a user as an originator or
potential recipient of a message or probe. An O/R name contains an O/R address.
OSI (Open Systems Interconnection). A set of standards used for the interconnection of
heterogeneous computer systems, thus providing universal connectivity.
OSI manager process. A process in the OSI/AS subsystem that performs subsystem
management functions. The OSI manager process is the focal point for all OSI
management activities. It maintains a management information base (MIB) that
contains the configuration information about the OSI environment. There is one OSI
manager process per OSI/AS subsystem.
OSI/MHS (Open Systems Interconnection/Message Handling System). The HP NonStop
implementation of an X.400 message handling system for HP NonStop systems.
OSI/MHS database. The database that consists of the registration database and OSI/MHS
configuration database.
OSI/MHS ISV. The installation subvolume for OSI/MHS The Install process creates this
subvolume as ZOSIMHS.
OSI/MHS subsystem. The set of all processes and files defined through the installation
procedure, and through SCF or management applications, to be part of an OSI/MHS
