link access
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 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, 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.
