TS/MP Pathsend and Server Programming Manual (H06.05+, J06.03+)

library A set of related files or common files that can be accessed by multiple programs or processes.

link An open of a server process within a server class. When a link manager—that is, a TCP or
a LINKMON process—sends a request to a PATHMON process for a link to a server in a
1.
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.
2. To examine, collect, associate together, and modify code and data blocks from one or more
object files to produce a target object file. On NonStop systems, linking for TNS/R native
object files is performed by the nld utility.
link access The actual transfer of data from a requester to a server process. In the Pathway environment, link
access is provided by TCPs and LINKMON 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 LINKMON process) on behalf of a requester. 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 requester 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 LINKMON 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 and NonStop Tuxedo
environments. LINKMON processes act as link managers for requesters and clients that use the
Pathsend procedure calls and other interfaces such as RSC/MP, 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 requesters 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
request through the PATHCOM interface. A management application can also interact with
subsystems other than the Pathway subsystem. Management applications use the Subsystem
Programmatic Interface (SPI) to send commands to subsystems and the Event Management Service
(EMS) to receive notification of significant events.
Message Section A section in the Data Division of a SCREEN COBOL source program that describes the data type,
size, and relative position (sequence) of each field in a message template. This section also
defines the editing and conversion that must be performed on each field. See also message-oriented
requester.
message-oriented
requester
A SCREEN COBOL requester that sends data from working storage to a device (or to a front-end
process that controls a device) and receives data from the device or process into working storage
by way of Message Section templates. SCREEN COBOL requesters that use the intelligent device
support (IDS) facility are message-oriented. These requesters use SEND MESSAGE statements
and their REPLY clauses in the Procedure Division to interact with the intelligent devices or front-end
processes. See also screen-oriented requester.
mixed data item A data item that contains both single-byte and double-byte characters; in a COBOL or SCREEN
COBOL program, these data items are declared as PIC X.
