SWITCH PATHMON Command
Consideration
All processes started by the PATHMON process and still running when the STOP
PATHMON command completes successfully are orphaned.
To avoid orphaned processes, first use the STATUS PATHWAY command, before
executing the STOP PATHMON command, to determine what type of processes are
running. Use the STATUS command on each type of object to find the names of the
active processes, then stop each process. After all processes are stopped, then
execute the STOP PATHMON command.
Errors
This table lists the most common error that can occur during the processing of the
STOP PATHMON command:
SWITCH PATHMON Command
Use the SWITCH command to direct the PATHMON process to exchange the function
of its primary process with the function of its backup process while the PATHMON
process is running.
This command does not change the PATHMON processor definitions in the
PATHMON configuration file.
Considerations
•
Use the STATUS PATHMON command to identify the CPUs in which the
PATHMON primary and backup processes are actually running after you have
repeatedly entered the SWITCH command.
•
Whenever the PATHMON primary or backup process is stopped more than 10
times by a STOP command, the PATHMON process delays creating a backup
process. The PATHMON process delays creating a backup process by 1 minute if
stopped 11 times, 2 minutes if stopped 12 times, and so forth.
However, the PATHMON process does not delay creating a backup process if any
of these occur:

*1045* REQUEST NOT VALID FOR
CURRENT STATE
You have issued a STOP PATHMON command
but the PATHMON process is not in the shutting-
down state.
Issue a SHUTDOWN2 PATHWAY command
before issuing the STOP PATHMON command.
