Objects and Processes Provided by Pathway/iTS
Pathsend requesters. (Under Pathway/iTS, the TCP is the link manager for
SCREEN COBOL requesters.)
•
Application Cluster Services (ACS) Subsystem Processes—these processes use
Pathsend requesters to provide link management functions for applications.
(Pathsend requesters are user applications that use Pathsend procedure calls to
send requests to server classes.) In TS/MP 2.3, ACS subsystem core processes
replace the TS/MP 2.0 LINKMON process. (Although TS/MP 2.3 has a ROUT
process with $ZLnn names, similar to what TS/MP 2.0 uses, the TS/MP 2.3 ROUT
is a redirector process that is part of the ACS subsystem. The TS/MP 2.3 ROUT
object is also located in the SYSnn subvolume, not in the SYSTEM subvolume.)
The ACS subsystem must be configured and started (that is, $ZACS must be
running) before using Pathsend requesters. For more information on ACS
subsystem, see the TS/MP Release Supplement.
•
Pathway Domain Management Interface (PDMI)—is a new management interface
introduced in TS/MP 2.3. It is an interactive management interface with a set of
commands to configure, operate, control, and collect information for multiple
PATHMON processes, with replicated configurations, under a single Pathway
domain. Additionally, TS/MP 2.3 has enhanced PATHMON and PATHCOM
processes, which now provide support for the new PDMI. For more information on
PDMI, see the TS/MP Release Supplement.
Objects and Processes Provided by Pathway/iTS
These elements of a Pathway environment are provided by the Pathway/iTS product.
Information about configuring and managing these items is covered in the Pathway/iTS
System Management Manual.
•
TCP objects—terminal control processes that run screen (SCREEN COBOL)
programs and coordinate communication between screen programs, input-output
devices or processes, server processes, and the PATHMON process.
•
TERM objects—definitions of tasks that use screen programs to control input-
output devices such as terminals and workstations, or input-output processes that
enable users to communicate with an OLTP application.
•
PROGRAM objects—templates for creating and starting temporary TERM objects.
Pathway Environment Configurations
Depending on your configuration, a Pathway environment may also include other
software, such as TMF and the run-time portion of the Remote Server Call (RSC)
product, and the Pathway Open Environment Toolkit (POET) run-time environment.
Note. PDMI is configured and managed by a new program, called PDMCOM, which
provides a command-line interface. The PDMCOM program is a superset of the
PATHCOM command interface and the PDMCOM object resides in $SYSTEM.SYSTEM,
by default.
