PATHMON
PATHMON is a monitoring process that defines and manages
server objects and -if your environment includes Pathway/iTS – TCPs, TERM
objects and program objects. Each PATHMON environment includes only one PATHMON
process.
PATHCOM
PATHCOM is command line interactive interface to communicate
with PATHMON process. As an alternative to using PATHCOM, management
application program can be written.
SERVER Object
Definitions of server classes is called SERVER object.
Server class is multiple copies are SERVER programs. Executing Server program
is called SERVER process.
LINKMON
LINKMON is process that manages communication between
PATHSEND process and SERVER Classes. PATHSEND processes are user application
which use PATHSEND procedure calls to send requests to SERVER classes.
Note: Above
objects and processes are provided by Nonstop TS/MP.
TCP objects
Terminal control process that runs screen(SCREEN COBOL)
programs and coordinate communication between screen programs, input-output
devices or processes, server processes and the PATHMON processes.
TERM Objects
Definitions of tasks that uses screen programs to control
input-output devices such as terminals and workstations.
Program object:
Templates for creating and starting temporary TERM objects. Above objects and processes are provided by the Pathway/iTS
product.
System Management Tools:
We can use one of two ways to configure and control
PATHMON-controlled objects in Pathway.
1.
Interactively, by entering commands
2.
Programmatically, by writing a management
application program.
Interacting with PATHMON:
Interactive way
PATHCOM $PPX (PATHMON process name)
6:56:34 (qdev) $AUDIT.C997240 14> PATHCOM $PPX
$X7CY: PATHCOM - T0845H09 - (01JUL13)
(C)2008-2013 Hewlett Packard Development Company, L.P.
Non-interactive way
IN-COMMAND
PATHCOM
/IN PWCMD, OUT $S.#LP, CPU 1, NOWAIT/ $PMX
OBEY Command:
>>PATHCOM $PMX
>> OBEY PWCMD
TACL Routines: TACL inline facility allow us to interact
with PATHMON in non-interactive way.
USING defines:
12>ADD DEFINE =CMD-FILE, CLASS MAP, FILE $DATA.PW.CONFIG
13> ADD DEFINE =OUT-FILE, CLASS SPOOL,LOC $S, REPORT
“CONFIG”
14> PATHCOM/IN =CMD-FILE, OUT =OUT-FILE/ $PMX
Configuring Global parameters
SET PATHWAY command is used to define the limits for your
overall configuration and to specify node-independent, owner and security
attributes.
Specifying
Limits:
Limits are global values
that determine the maximum number of objects of each type that you can define
when you are ready to configure individual objects. For example, suppose that
you suppose that you want to indicate that your system will permit a maximum
of:
- 5
server classes
- 25
server processes
- 5
server STARTUP messages
- 7
server ASSIGN messages
- 5
server PARAM messages
To establish these limits, you can use these commands.
= SET PATHWAY MAXSERVERCLASSES 5
= SET PATHWAY MAXSERVERPROCESSES 25
= SET PATHWAY MAXSTARTUPS 5
= SET PATHWAY MAXASSIGNS 7
= SET PATHWAY MAXPARAMS 5
PATHMON process save the configuration details in the memory
until you start the PATHMON process. After starting PATHMON process it will
write to PATHMON configuration file.
Specifying Owner and Security Attributes:
