SWITCH PM
Consideration
All processes started by the PATHMON process and still running when the STOP PM
command completes successfully are orphaned. Orphaned processes are processes
no longer recognized by the PATHMON process.
To avoid orphaned processes, first use the STATUS PATHWAY command, before
executing the STOP PM 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 and then stop each process. After all processes are stopped, execute the
STOP PM command.
SWITCH PM
Use the SWITCH PM 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 CPU definitions in the PATHMON
configuration file.
Continuation
You cannot use continuation with this command.
