NonStop TS/MP PATHCOM Interface
•
The Parallel Transaction Processing (PTP) environment, which runs in the Guardian
operating environment, supports the CICS command-level API, and enables CICS
applications to run on Tandem NonStop systems and to communicate with other
CICS applications.
•
The Pathway transaction-processing environment, which also runs in the Guardian
operating environment, provides a client/server model for both terminal-based and
workstation-based applications, with the benefits of the Tandem fundamentals.
Transactions can be initiated by workstations, terminals, intelligent devices, and
general devices. The Pathway environment always includes the NonStop TS/MP
core service product. It might also include other software, such as the Pathway/TS
product and the Remote Server Call (RSC) product.
NonStop TS/MP PATHCOM Interface
The PATHCOM interface is an interactive interface to the NonStop TS/MP core
services. Through PATHCOM, you send commands and instructions to the PATHMON
process-management process. Process management includes all tasks related to the
starting, monitoring, and stopping of server processes and other processes specific to a
transaction-processing environment.
In a PTP environment, use PATHCOM to:
•
Start, stop, restart, and display information (configuration, status, and statistics)
about a PTP region
•
Specify attributes for server classes and server processes, such as the Guardian
security for a server class, the priority at which the server class will run, the number
of server processes per server class, and the processors in which a server process
will run
•
Alter and delete server class definitions
•
Start and stop server classes
•
Control the NonStop TS/MP monitor process (PATHMON)
In a Pathway environment, use PATHCOM to:
•
Configure objects controlled by the PATHMON process
•
Reconfigure an existing PATHMON environment to add new terminals, screen
programs, terminal control processes (TCPs), and servers as required
•
Monitor a PATHMON environment to obtain statistics on the behavior of the objects
controlled by PATHMON
In a NonStop TUXEDO environment, the NonStop TS/MP infrastructure is virtually
transparent to the NonStop TUXEDO administrator. For example, when the
administrator starts a NonStop TUXEDO application, the underlying NonStop TS/MP
processes are automatically started and maintained. The administrator will notice a few
added parameters in the configuration file, however, and might want to use PATHCOM
to check the status of the underlying service.
