Goal
The goal of this document is to provide some details about the Alive check mechanism and to provide some guidance on how to manage hang-up situations on OPL domains.
There is a mechanism in place that monitors the domains and detects any hang-up situation : the Alive Checking / Monitoring (aka Host Watchdog).
There are 2 parts :
-
the Alive monitoring which is monitored by SCF driver (Solaris[TM]) and XSCF,
-
the Alive monitoring which is monitored by POST/OBP and XSCF.
