Maintaining a PATHMON Environment

Exchanging Primary and Backup CPUs
To direct the memory dump for the PATHMON process to a file named PMDUMP,
enter:
= CONTROL PATHMON, DUMP ON (FILE PMDUMP)
The PATHMON configuration file is updated to reflect these changes.
To change the file for logging output, use the PATHCOM commands LOG1 and LOG2.
For example, to specify $0 as the log file for errors reported in tokenized event
message format, and to specify the disk file LOGCOPY as a log file for both error and
status change information in text format, enter:
= LOG1 $0, EVENTFORMAT
= LOG2 LOGCOPY, STATUS
Be sure to create a disk file (using the FUP CREATE command) for logging purposes
before specifying it.
Exchanging Primary and Backup CPUs
You can exchange the primary and backup CPUs used for your PATHMON process by
using the SWITCH command, as shown in this example:
= SWITCH PATHMON
At any time after this operation, you can also reestablish the primary processor for the
the PATHMON process (as recorded in the PATHMON configuration file) by using the
PRIMARY command, as shown in the next example:
= PRIMARY PATHMON
Neither of these operations alters information recorded in the PATHMON configuration
file.
Changing the Owner and Security Attributes
You can change OWNER and SECURITY attributes by using the SET PATHWAY
command. For example, these commands specify that only the owner—user ID 8,60—
can modify the PATHMON environment:
= SET PATHWAY OWNER 8,60
= SET PATHWAY SECURITY "O"
You cannot change the OWNER and SECURITY attributes while a PATHMON
environment is running; you must first shut down the environment, as shown in this
example. Recall that when you configure global limits after a shutdown, you must
specify all limits, not just the ones you are changing. Once you have specified old and
new limits, and changed the OWNER and SECURITY attributes, you must use the
COLD! start option to restart the PATHMON environment:
= SHUTDOWN2, MODE ORDERLY
= OPEN $PM
.
. (specify old limits)
