Configuring TCP, TERM, and PROGRAM Objects
Configuring TCP, TERM, and PROGRAM
Objects
After specifying global limits and issuing the START command (as described in the
TS/MP System Management Manual), you configure TCPs and the TERM, PROGRAM
and SERVER objects that run under the PATHMON process to support your
application. Note that only the TCPs and the TERM and PROGRAM objects are
configured as part of the Pathway/iTS product. SERVER objects are configured with
TS/MP, described in the TS/MP System Management Manual.
You create and control objects using PATHCOM commands and naming conventions
that you determine. The SET and ADD commands define and change object attributes.
The SHOW command allows you to display attributes for an object. PATHCOM
maintains a list of attributes that describe configuration information for each object:
how it relates to other objects and how it should be managed by the PATHMON
process. The attributes for a TCP, for instance, specify the TCP’s name, the
processors on which the TCP runs, the TCP’s execution priority, the name of the file
that contains the object code that the TCP runs, and other characteristics of the TCP.
For a complete description of the SET, ADD, and SHOW commands and guidelines for
using them, in addition to guidelines for object naming conventions, see the TS/MP
System Management Manual. For descriptions of the SET, ADD, and SHOW
commands as they apply to TCP, TERM, and PROGRAM objects, see Sections 9, 10,
and 11, respectively, in this manual.
Configuring TCPs
As a multitasking process, a TCP can concurrently manage many user terminals and
execute many SCREEN COBOL programs. To accomplish this work, the TCP runs its
TERM objects as tasks, interleaving the concurrent processing of requests from many
input-output devices or processes. This multithreading allows the TCP to handle
complex groups of operations for many users at the same time.
The tasks performed by the TCP include:
•
Interpreting and executing a SCREEN COBOL program for each TERM or
PROGRAM object (for web clients, this program is the gateway program provided
by Pathway/iTS)
•
Verifying and storing terminal context data in an extended data segment
•
Establishing links for screen programs with server processes
•
Coordinating with the router processes for web clients and sockets IDS requesters
•
Servicing SCREEN COBOL SEND requests by sending request messages to
server processes and receiving reply messages back
•
Gathering statistics about TERM objects, server processes, and the TCP itself
