PDMCOM RUN Options
You can enter the remainder of the commands from your terminal, or you can create a
command file that contains the commands and then run the commands in that file.
Running PDMCOM interactively is most useful when you plan to enter only a few
commands. It is a good way to monitor the status of objects, dynamically start and stop
objects, run a program, and send messages to user terminal operators about changing
conditions. It is generally easier and faster, however, to set up lengthy configurations
non-interactively.
PDMCOM RUN Options
The command to run PDMCOM, like the command to run the PATHMON process,
allows you to select several RUN options. For instance, you can select the CPU in
which PDMCOM runs or specify a device other than your terminal as the destination of
output from PDMCOM. If you do not specify these options, the operating system
supplies standard default values.
Getting HELP for PDMCOM Syntax and Errors
To use the HELP command through PDMCOM, the PDMHELP file must also reside in
the same subvolume as PDMCOM.
You can display a complete list of all PDMCOM commands available by entering the
following PDMCOM command:
PDMI 1>> HELP COMMANDS
You can also display help for a specific command as follows:
PDMI 2>> HELP START
In response, PDMCOM displays:
START { <entity-list> }
{ PATHWAY <pw-starttype> [ ! ] }
{ <scname> , PROCESS <process-name> }
{ <termname-list> [ , INITIAL <puname> ] }
You can also request information about specific command parameters. For instance, to
request information about the <
pw-starttype> parameter of the START command,
enter:
PDMI 3>> HELP <pw-starttype>
In response, PDMCOM displays:
<pw-starttype> ::= { COLD } { COOL }
Finally, you can also request help in interpreting message numbers that appear on
object status reports from the PATHMON processes. For example, if you encounter
