deleted) by the PATHMON process in response to a RUN PROGRAM command, using
a template you configure as a PROGRAM object. (A PROGRAM object is simply a
mechanism for creating temporary TERM objects as they are needed.)
Router Processes
A router process listens and distributes connection requests from web clients and from
intelligent devices that use the raw sockets protocol. A router process works together
with a TCP that is interpreting and executing either the Pathway/iTS gateway process
(for web clients) or a user-written IDS requester (for sockets intelligent devices). Each
router process is configured with a TCP/IP port used to associate an application with
connection requests.
The router processes distribute connection requests from web clients or intelligent
devices to started TERM objects within the TCPs in such a way that the connection
load is optimally balanced among all the TCPs in the Pathway environment. When all
the TERM objects in all the configured TCPs are in use, the router queues new
connection requests until a TERM object is available. The router also queues the
TERM objects that are ready for a connection until a connection request arrives.
Transaction Sources
A variety of devices and processes may interact with the PATHMON process and its
objects to supply required resources and services or to make requests. These include
PATHCOM or a management application process, in addition to terminals controlled by
TCP objects. In addition, these devices and processes might include:
•
Browser-based web clients
•
Personal computers and workstations (using the RSC/MP product)
•
External TCP objects, that is, terminals running outside of your PATHMON
environment
•
Intelligent devices such as an automated teller machine (using intelligent device
support (IDS) )
•
SNA devices (using the SNAX High-Level Support (SNAX/HLS) product)
•
Unsupported or special-function I/O devices (using the Extended General Device
Support (GDSX) product)
•
Pathsend processes (using Pathsend procedure calls to communicate with the
LINKMON process)
Figure 1-4 on page 1-14 shows examples of devices that interact with PATHMON-
controlled objects, either directly or through the LINKMON process. Note that the
LINKMON, PATHMON, and PATHCOM processes are provided by TS/MP. Server
processes are defined and managed under TS/MP. For information on these
processes, see the TS/MP System Management Manual.
