printing distributor. An EMS distributor process that obtains formatted text for select event
messages and distributes it to a printer or other display device, or to a file.
priority. In OSI/MHS, the order in which alternate routes are attempted. Priority values are
relative only to the other priorities for a particular MTA.
Private Management Domain. See PRMD.
PRMD (Private Management Domain). An X.400 domain managed by a private
organization, such as a corporation. See also domain.
probe. An X.400 communication sent by an originator into the MTS to test the likelihood of
delivery of a message or report. It consists of an envelope and the description of the
actual content of the message or report. The envelope is similar to, but not the same as,
an envelope that would be used for an actual message or report.
process. A running entity that is managed by the operating system, as opposed to a program,
which is a collection of code and data. A process is a unique execution of a program.
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.
