PROCESS object. An object type, used in OSI/MHS management interfaces, that defines a
process to the OSI/MHS subsystem. You use the PROCESS object to trace and
monitor OSI/MHS processes.
programmatic command. In DSM, a command issued by a program rather than by a
human operator. See also interactive command.
programmatic interface. A mechanism by which a program can interact with other
software.
programmed operator. In DSM, a management application that performs functions that
might otherwise be performed by a human operator.
protocol. The set of rules governing the format and meaning of the frames, packets, or
messages that are exchanged by the peer entities within a layer. See also service.
PSAP (presentation service access point). A logical location between the Presentation and
Application Layers, through which presentation services are made available to local
users and through which application services are made available to remote systems.
PSEL (presentation selector). An address at the boundary between the Presentation and
Application Layers, through which connections are established and maintained. A
single PSEL can service one or more connections simultaneously and can refer to one
or more presentation service access points (PSAPs).
P-selector. See PSEL.
PTrace. A program that enables you to display trace files. Trace criteria are specified with
SCF.
queue file. In the Transfer X400 gateway, a file in the queue manager that consists of three
logical queues: the ADMIN queue with entries for MR group registration, the
MESSAGE queue with entries for import work, and the EXPORT queue with entries for
export work.
queue manager. A queuing facility that lets Transfer requesters add an entry and retrieve an
entry from a queue for processing. The queue manager can be used independently of
Transfer; it is automatically installed when you configure the Transfer X400 gateway
and is also required for gateways using the Gateway Programmatic Interface (GPI).
reason code. A value indicating why a message could not be delivered (called a “non-
delivery-reason-code,” in the X.411 standard).
