Starting and Stopping a PATHMON Environment

Configuring the PATHMON Process
For example, these commands indicate that the owner is the super ID and that only the
owner can add, modify, or delete PATHMON-controlled objects:
= SET PATHWAY OWNER 255,8
= SET PATHWAY SECURITY "O"
Configuring the PATHMON Process
Use PATHCOM commands to configure your PATHMON process. For example, you
might want to specify a backup processor or request error dumping.
Specifying a Backup Processor
Because the PATHMON process is a crucial control process, it typically runs with a
backup process.
To define the backup process’s location, use the SET PATHMON command. For
example, this command selects processor 1 as the processor for the backup process:
= SET PATHMON BACKUPCPU 1
You must specify a processor other than the one in which the PATHMON primary
process is currently running.
Requesting Error Dumping
You can request error dumping by specifying either the SET PATHMON DUMP ON
command or the CONTROL PATHMON, DUMP ON command.
•
Use the SET PATHMON command if you want to request error dumping and you
have not yet started your Pathway environment.
•
Use the CONTROL PATHMON command if you want to request error dumping but
you have already started your Pathway environment. This command is described
in more detail in Changing Backup CPUs and Dump Files on page 5-19.
In case of an internal or fatal error, the PATHMON process generates an error dump
and writes it to a file. You may specify a name for the dump file if you wish. For
example, this command directs the PATHMON process to write error information to a
file named PMDUMP:
= SET PATHMON DUMP ON (FILE PMDUMP)
The PATHMON process writes the information in its data stack to PMDUMP.
If you request your HP representative’s help in analyzing a problem, the representative
will likely require a DUMP file. It is therefore recommended that DUMP be set to ON
for production systems.
