NonStop operation
NonStop operation. A Tandem system behavior characterized by continued operation even
when a component fails, when equipment is being repaired or replaced, or while new
processors or peripheral devices are being added to the system. Legally used only to
describe the Tandem Nonstop system or its features, such as NonStop process pairs.
Obey file. See command file
.
object. (1) One or more of the devices, lines, processes, and files in a Tandem subsystem; any
entity subject to independent reference or control by one or more subsystems. (2) In
Subsystem Control Facility (SCF), a resource controlled by an SCF subsystem. SCF
objects include processes, disks, disk files, and data communications lines. Each object
has an object type and an object name. See also object name
and object type.
object name. A unique name for a Subsystem Control Facility (SCF) object within an SCF
subsystem.
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 may have the object type SU. An SCF subsystem has a set of object types for
the objects it manages.
parallel sessions. In SNA, two or more concurrently active sessions between the same two
logical units using different pairs of network addresses. Each session can have
independent session parameters.
PARAM. A Tandem Advanced Command Language (TACL) command you can use to create
a parameter and give it a value. The TACL process stores the values of parameters
assigned by the PARAM command and sends the values to applications, such as
SYSGENR, that request parameter values.
partner LU. An LU in session with the LU under discussion.
password. A form of system security whereby users must identify themselves using a unique,
nondisplayed code before being allowed to gain access to the system, an application, or
data within a file.
PATHCOM. (1) The interactive interface to the PATHMON process, through which users
enter commands to configure and manage Pathway applications. (2) The process that
provides this interface.
PATHMON environment . The servers, server classes, TCPs, terminals, SCREEN COBOL
programs, and tell messages that run together under the control of one PATHMON
process.
PATHMON process. The central controlling process in the Pathway environment. The
PATHMON process maintains configuration-related data; grants links to server classes
in response to requests from TCPs (terminal control processes) and LINKMON
processes; and performs all process control (starting, monitoring, restarting, and
stopping) of server processes and TCPs.
