link management
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,
NonStop TUXEDO, and PTP environments. LINKMON processes act as link managers
for requesters 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.
manageability. The ability to easily and comprehensively manage a subsystem, system, or
network.
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.
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-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.
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.
