PATHMON Environment Control Commands
NonStop TS/MP System Management Manual—541819-001

CONTROL PATHMON Command
If you do not specify the volume and subvolume portions of file-name, the
PATHMON process creates a dump file on the same subvolume as the
PATHMON configuration file.
The format of the file name is ZZPMnnn, where nnn is a 3-digit number. The
file code is 130.
OFF
directs the PATHMON process not to write data stack to a file when it
encounters an internal error.
DUMPMEMORY (FILE file-name )
Forces the PATHMON process to write the information in its data stack to a file.
Note that the DUMPMEMORY option is not a substitute for setting the DUMP
option to ON. DUMPMEMORY is primarily useful in a controlled troubleshooting
situation where you need to take a snapshot of the internal state of the PATHMON
process at a particular time—before it encounters a fatal error. You should only
force a dump if your representative specifically requests it.
FILE file-name
specifies the name of the file that the PATHMON process creates for its dump
operation.
If you do not specify file-name, the PATHMON process creates a dump file
on the same subvolume as the PATHMON configuration file. The format of the
file name is ZZPMnnn, where nnn is a 3-digit number. The file code is 130.
Considerations
•
If the primary PATHMON process is running in the processor defined for the
backup PATHMON process because of a SWITCH command or some other
processor change, the BACKUPCPU option causes the PATHMON process to
change the PATHMON configuration file so that it contains the current processor
numbers for both the primary and backup PATHMON processes.
•
When you cool start a Pathway environment (that is, when you use a pre-existing
configuration file to start a Pathway environment) after using the CONTROL
PATHMON command, the PATHMON process uses the values you changed with
the CONTROL PATHMON command.
•
When the creation of a backup process fails more than ten times, the PATHMON
process delays trying to create a backup process. The delay is 1 minute if stopped
Note. If file-name specifies a file that already exists and the PATHMON process attempts to
dump to this file, a dump is not performed and error *1123* PATHMON, MEMORY DUMP NOT
TAKEN is generated.
