TS/MP 2.5 System Management Manual

intelligent device
support (IDS)
facility
A feature of the TCP that supports access to Pathway server classes by intelligent devices. This
facility allows SCREEN COBOL requestor programs to interact with external processes that, in
turn, control devices such as personal computers, automated teller machines, and point-of-sale
devices.
intelligent mode An operating mode in which data and messages are sent between an intelligent device and the
Pathway environment. See also conversational mode (definition 1), intelligent device, and
message-oriented requestor.
interactive mode An operating mode in which commands are entered from a terminal keyboard.
interoperability The ability to communicate, execute programs, or transfer data between dissimilar environments.
interoperate To communicate, execute programs, or transfer data between dissimilar environments.
interprocess
communication
(IPC) message
The unit of communication between requestors and servers. An IPC message consists of a request
message and a reply message.
IPC message See interprocess communication (IPC) message.
keyword A word in a command string or programming language that must be spelled and positioned in
a prescribed way, usually to indicate the meaning of an adjacent parameter.
library A set of related files or common files that can be accessed by multiple programs or processes.
linear
expandability
See scalability.
link
An open of a server process within a server class. When a link manager—that is, a TCP or
a ACS subsystem process—sends a request to a PATHMON process for a link to a server
•
in a specified server class, the PATHMON process selects a server process in that server
class (possibly starting a new server process if necessary) and then returns the name of the
server process to the requesting link manager. See also link granting and link manager.
• To examine, collect, associate together, and modify code and data blocks from one or more
object files to produce a target object file. On Tandem NonStop systems, linking for TNS/R
native object files is performed by the nld utility.
link access The actual transfer of data from a requestor to a server process. In the Pathway environment, link
access is provided by TCPs and ACS subsystem processes. See also link granting.
link granting The process of selecting a particular server process in a server class to handle a request from a
link manager (TCP or ACS subsystem process) on behalf of a requestor. In the Pathway
environment, link granting is done by the PATHMON process. See also link and link access.
link management The act of coordinating the sharing of links between requestor or client processes and server
processes.
link manager A process that requests links to server processes and provides link access after the link is granted.
TCPs and ACS subsystem processes are the link managers in the Pathway environment. See also
link access and link granting.
LINKMON process A Guardian process that supports access to servers in the Pathway, NonStop TUXEDO, and PTP
environments. LINKMON processes act as link managers for requestors and clients that use the
Pathsend procedure calls and other interfaces such as RSC, POET, and the NonStop TUXEDO
ATMI. See also link manager.
lock A mechanism that coordinates access to the same data; locks are either shared or exclusive.
log file See PATHMON log file and event log file.
low PIN A process identification number (PIN) in the range 0 through 255. (PIN 255 is reserved by the
system; it is never assigned to a running process, but is used by high-PIN processes to communicate
with low-PIN processes.) See also process identification number (PIN) and high PIN.
MAKEUL A TACL macro used to perform pTAL compilation of user-written conversion routines for use with
the Pathway/TS TCP and SCREEN COBOL requestors and to create the TNS/R native TCP user
library containing these routines.
manageability The ability to easily and comprehensively manage a subsystem, system, or network.
management
application
An application program that automates configuration and management tasks. Such a program
can request from the PATHMON process the same kinds of services that system managers can
