NonStop TS/MP Objects and Processes
NonStop TS/MP Objects and Processes
This subsection contains additional detail on the transaction services objects and
processes provided by the NonStop TS/MP product. Information on defining and
managing these items is provided in this manual.
PATHMON Object
The PATHMON object represents the PATHMON process. The PATHMON process
and the objects it controls make up the PATHMON environment. Each PATHMON
environment has only one PATHMON process, the main control process in the
environment.
The PATHMON process defines, configures, and manages all the objects under its
control. These objects include server objects and—if your environment includes
Pathway/iTS—TCPs, TERM objects, and PROGRAM objects. The PATHMON
process creates and maintains a file in which it stores the configuration information for
each of these objects. When your application is running, the PATHMON process
communicates with all the objects, receiving information about them and managing
their activities.
The PATHMON process enforces global limits you set for the environment and
monitors the operation of the objects under its control by performing these:
•
Keeping a record of the object definitions in the PATHMON configuration file
•
Starting SERVER processes (available only if you are running the NonStop TS/MP
product)
•
Starting TCPs, TERM objects, and PROGRAM objects (available only if you are
running the Pathway/iTS product)
•
Facilitating access between link managers, such as LINKMON processes or TCPs,
and server processes to support requester/server communication
•
Reporting status information about PATHMON-controlled objects
•
Reporting system errors caused by invalid or unsuccessful operations
•
Shutting down all or part of a PATHMON environment by stopping individual
objects
•
Automatically restarting failed objects
PATHWAY Object
The PATHWAY object represents the entire set of objects controlled by the PATHMON
process. You refer to it to set attributes affecting the entire PATHMON environment,
start up and shut down the PATHMON-controlled objects, and obtain status
information about the PATHMON environment. For information on the attributes that
